COUNCIL DIRECTIVE 96/49/EC of 23 July 1996 on the approximation of the laws of the Member States with regard to the transport of dangerous goods by rail THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty establishing the European Community, and in particular Article 75 thereof, Having regard to the proposal from the Commission (1), Having regard to the opinion of the Economic and Social Committee (2), Acting in accordance with the procedure referred to in Article 189c of the Treaty (3), (1) Whereas in recent years the transport of dangerous goods by rail has considerably expanded, thus increasing the risks of accidents occurring; whereas measures must therefore be taken to ensure that such transport is carried out under the best possible conditions of safety; (2) Whereas all Member States are Contracting Parties to the Convention concerning international carriage by rail (COTIF), which, in Appendix B thereto, defines uniform rules concerning the contract for international carriage of goods by rail (CIM), Annex 1 to which constitutes the regulations concerning the international carriage of dangerous goods by rail (RID); whereas the geographical scope of the Convention extends beyond the Community; (3) Whereas the Convention does not cover the national carriage of dangerous goods by rail; whereas it is therefore important to ensure the uniform application of harmonized safety rules throughout the Community; whereas the most appropriate way of achieving this is to align the laws applied by the Member States on the RID; (4) Whereas, in compliance with the principle of subsidiarity, these laws must be approximated in order to ensure a high level of safety for national and international transport operations, to guarantee the elimination of distortions of competition by facilitating the free movement of goods and services throughout the Community and to ensure consistency with the other Community provisions; (5) Whereas the provisions of this Directive are without prejudice to the commitment entered into by the Community and its Member States, in accordance with the goals set under Agenda 21, Chapter 19, at the UNCED Conference in June 1992 in Rio de Janeiro, to strive for the future harmonization of systems for the classification of dangerous substances; (6) Whereas no specific Community legislation yet governs the safety conditions under which biological agents and genetically modified micro-organisms, regulated under Directives 90/219/EEC (4), 90/220/EEC (5) and 90/676/EEDC (6) should be transported; (7) Whereas the provisions of this Directive are without prejudice to the application of other Community provisions in the field of worker safety and environmental protection; (8) Whereas the Member States must be able to apply specific traffic regulations to the transport on their territory of dangerous goods by rail; (9) Whereas, the Member States should retain the right, with regard to the transport of dangerous goods by rail, provisionally to implement rules in conformity with the United Nations recommendations on the multimodal transport of dangerous goods, in so far as the RID is not yet harmonized with those regulations, which should facilitate the inter-modal transport of dangerous goods; (10) Whereas each Member State must retain the right to regulate or prohibit, strictly for reasons other than safety, the internal transport of certain dangerous goods by rail; (11) Whereas account should be taken of the more stringent safety measures applied in the Channel Tunnel because of its specific characteristics, in particular its route and length; whereas provision should also be made for Member States to be able to introduce the same kind of measures where similar situations arise; whereas it must be possible for some Member States to apply more stringent standards for material intended for transport because of the ambient temperature in their countries; (12) Whereas, in view of the volume of investment required in this sector, a transitional period should be laid down to enable Member States to retain temporarily certain specific national provisions concerning construction requirements or the use of tanks, receptacles, packaging or an emergency action code; (13) Whereas the introduction of new developments in technology and industry must not be hindered; whereas temporary derogations should be provided for that purpose; (14) Whereas the provisions of the RID authorize the conclusion of agreements derogating therefrom; whereas the large number of agreements concluded bilaterally between Member States impedes the free provision of dangerous-goods transport services; whereas including the necessary provisions in the Annex to this Directive should overcome the need for such derogations; whereas provision should be made for a transitional period during which the Member States may continue to apply existing agreements amongst themselves; (15) Whereas the transport of dangerous goods by rail to or from a third country is authorized, provided it is carried out in accordance with the requirements of the RID; whereas, however, in the case of transport operations from and to the Republics of the former Soviet Union which are not contracting parties to the COTIF, the Member States are entitled to adopt appropriate measures with regard to such operations; whereas they guarantee a level of safety equivalent to that provided for in the RID; (16) Whereas it must be possible to adapt this Directive rapidly to technical progress, notably by adoption of the new provisions laid down within the framework of the RID; whereas, for that purpose, a Committee should be set up and a procedure established for close cooperation between Member States and the Commission within that Committee, HAS ADOPTED THIS DIRECTIVE: CHAPTER I Scope Article 1 1. This Directive shall apply to the transport of dangerous goods by rail within Member States or between Member States. Member States may, however, exempt from the scope of this Directive the transport of dangerous goods conducted by means of transport equipment belonging to or under the responsibility of the armed forces. 2. This Directive shall not, however, affect the Member State's right, having due regard to Community law, to lay down specific safety requirements for the national or international transport of dangerous goods by rail, in so far as the Annex thereto does not cover that area, in particular as regards, inter alia: - the running of trains; - the marshalling of freight wagons in trains in national traffic; - operating rules for operations ancillary to transport such as marshalling and stabling; - the training of staff and the management of information concerning the dangerous goods transported; - special rules for the transport of dangerous goods in passenger trains. Article 2 For the purposes of this Directive: - 'RID` shall mean the regulations concerning the international carriage of dangerous goods by rail, appearing as Annex I to Appendix B to the Convention concerning international carriage by rail (COTIF), together with its amendments; - 'CIM` shall mean the uniform rules concerning the contract for international carriage of goods by rail, appearing as Appendix B to the Convention concerning international carriage by rail (COTIF), together with its amendments; - 'dangerous goods` shall mean those substances and articles the transport by rail of which is prohibited or authorized only on certain conditions by the Annex to this Directive; - 'transport` shall mean any operation for the transport of dangerous goods by rail, conducted wholly or partially within the territory of a Member State, including the activities of loading, unloading and transfer to or from another mode of transport and the stops necessitated by the circumstances of the transport, covered by the Annex to this Directive, without prejudice to the arrangements laid down by the laws of the Member States concerning liability in respect of such operations; it shall not include transport wholly performed within the perimeter of an undertaking. Article 3 1. Without prejudice to Article 6, dangerous goods the transport of which is prohibited by the provisions of the Annex may not be transported by rail. 2. Save as otherwise provided in this Directive and without prejudice to the rules on market access for railway undertakings or to the rules generally applicable to the transport of goods by rail, the transport of dangerous goods by rail shall be authorized, subject to compliance with the rules laid down in the Annex. CHAPTER II Derogations, restrictions and exemptions Article 4 Each Member State may, for the purposes of national rail transport operations within its territory, retain provisions of its national law on the transport of dangerous goods by rail which are consistent with the United Nations recommendations on the transport of dangerous goods, until such time as the Annex to this Directive is revised to reflect those recommendations. In such cases, the Member State concerned shall inform the Commission thereof. Article 5 1. Without prejudice to other Community provisions, each Member State shall retain the right to regulate or prohibit, strictly for reasons other than safety during transport connected in particular with national security or environmental protection, the transport of certain dangerous goods within its territory. 2. (a) For transport via the Channel Tunnel, France and the United Kingdom may impose more stringent provisions than those provided for in the Annex. The Commission shall be informed of such provisions and it shall inform the other Member States. (b) Where a Member State considers that stricter provisions should be applied to transport through tunnels with characteristics similar to the Channel Tunnel within its territory, it shall inform the Commission. The Commission, acting in accordance with the procedure laid down in Article 9, shall decide whether the tunnel in question has similar characteristics. Provisions adopted by a Member State shall be notified to the Commission, which shall inform the other Member States. (c) A Member State in which the ambient temperature is regularly lower than - 20 °C may impose more stringent standards as regards the operating temperature of material intended for use in the national transport of dangerous goods by rail within its territory until provisions on the appropriate reference temperatures for given climatic zones are incorporated in the Annex. 3. If, on the occasion of an accident or an incident, a Member State considers that the safety provisions applicable have been found to be insufficient to limit the hazards involved in the transport operation and if there is an urgent need to take action, that Member State shall notify the Commission at the planning stage of the measures which it proposes to take. Acting in accordance with the procedure laid down in Article 9, the Commission shall decide whether the implementation of the measures in question should be authorized and shall determine the duration thereof. 4. Member States may maintain all national provisions applicable on 31 December 1996 to the transport and packaging of substances containing dioxins or furans. Article 6 1. Each Member State may authorize the transport by rail within its territory of dangerous goods classified, packed and labelled in accordance with international requirements for maritime or air transport whenever the transport involves a sea or air voyage. Where a national or international journey involves carriage by sea, a Member State may apply provisions additional to those of the Annex to take account of international rules governing maritime transport, including international rules governing ferry transport. 2. The provisions of the Annex concerning the format of transport documentation and the use of languages in marking or in the documentation required shall not apply to transport operations confined to the territory of a single Member State. A Member State may authorize the use of documentation and languages other than those provided for in the Annex for transport operations confined to its territory. 3. Within its territory a Member State may allow the use of rail wagons constructed before 1 January 1997 which do not conform with the provisions of this Directive, but were constructed according to national provisions in force on 31 December 1996, provided that those wagons are maintained to the required safety levels. 4. A Member State may retain national provisions in force on 31 December 1996 relating to the construction, use and conditions of carriage of new tanks, and new receptacles as defined in Class 2 of the Annex, which differ from the provisions of that Annex, until references to standards for the construction and use of tanks and receptacles are added to the Annex, with the same binding force as the provisions therein, but in any event no later than 31 December 1998. Receptacles and tanks constructed before 1 January 1999 and maintained to the required safety levels may continue to be used under the original conditions. 5. A Member State may retain national provisions other than those in the Annex with regard to the reference temperature for the transport in its territory of liquefied gases or mixtures of liquefied gases, until provisions relating to appropriate reference temperatures for designated climatic areas are incorporated into European standards and referred to in the Annex. 6. A Member State may allow the use, in transport within its territory, of packaging constructed but not certified in accordance with the RID before 1 January 1997, provided that such packaging bears the date of its manufacture, is capable of passing the tests laid down in national provisions in force on 31 December 1996 and provided that they are maintained to the relevant safety levels (including testing and inspection where required), according to the following scheme: metal intermediate bulk containers and metal drums exceeding 50 litres in capacity may be used for up to 15 years after the date of their manufacture; other metal packagings and all plastic packagings may be used for up to five years after the date of their manufacture, but not after 31 December 1998. 7. A Member State may authorize the transport within its territory of certain dangerous goods packed before 1 January 1997 until 31 December 1998, provided that the goods are classified, packed and labelled in accordance with the requirements laid down in national provisions in force before 1 January 1997. 8. A Member State may retain the provisions of its national legislation which are in force on 31 December 1996 and relate to the display of an emergency action code in place of the hazard identification number, laid down in the Annex, for national rail transport operations conducted within its territory. 9. Any Member State may, after consulting the Commission, maintain provisions less stringent than those in the Annex for the transport by rail within its territory of small quantities of certain dangerous goods, with the exception of substances having a medium or high level of radioactivity. 10. A Member State may authorize within its territory ad hoc transport operations involving dangerous goods or transport operations which are prohibited by the Annex or transport operations performed under conditions different from those laid down in the Annex. 11. With due regard to Community law, this Directive shall not prejudice the right of a Member State, after consultation with the Commission, to authorize regular transport operations on particular designated routes within its territory, of dangerous goods, forming part of a defined industrial process, which are either prohibited by the Annex or are performed under conditions different from those laid down in the Annex where those operations are of a local nature and are tightly controlled under clearly specified conditions. 12. Provided that there is no loss of safety, a Member State may grant temporary derogations from the Annex for the purpose of carrying out within its territory the trials necessary before the amendment of that Annex in order to adapt them to technological and industrial developments. The Commission shall be informed accordingly and shall in turn inform the other Member States. Those temporary derogations, agreed among the Member States' competent authorities on the basis of the Annex, shall take the form of a multilateral agreement proposed to all the Member States' competent authorities by the authority that takes the initiative on any agreement. The Commission shall be informed. The derogations referred to in the first and second subparagraphs shall be applied without discrimination on grounds of the nationality or place of establishment of the consignor, operator or consignee; they may last for up to five years and shall be non-renewable. 13. A Member State may, until 31 December 1998 at the latest, apply existing agreements with other Member States, without discrimination on grounds of the nationality or place of establishment of the consignor, operator or consignee. Any future derogations shall comply with paragraph 12. 14. In accordance with Community law, this Directive shall not affect a Member State's right, after consulting the Commission, to authorize the transport of dangerous goods under conditions less stringent than those laid down in the Annex to this Directive in the case of local transport over short distances within the perimeters of ports, airports or industrial sites. Article 7 1. Subject to national or Community provisions on market access, the transport of dangerous goods by rail between Community territory and third countries shall be authorized in so far as it complies with the requirements of the RID. 2. This Directive shall not affect a Member State's right, after informing the Commission, to adopt regulations for its territory on the transport of dangerous goods by rail from and to those Republics of the former Soviet Union that are not contracting parties to the COTIF. Such regulations shall apply only to the transport of dangerous goods by rail (in packaging, in bulk or in tanks) by means of railway wagons authorized in a State which is not a contracting party to the COTIF. By means of appropriate measures and obligations the Member States concerned shall guarantee the maintenance of a level of safety equivalent to that provided for in the RID. In the case of certain Member States the provisions referred to in this paragraph shall apply only to tank wagons. CHAPTER III Final provisions Article 8 The amendments necessary to adapt the Annex to scientific and technical progress in the fields covered by this Directive, in particular to take account of amendments to the RID, shall be adopted in accordance with the procedure laid down in Article 9.

CHAPTER 1.7 General requirements concerning Class 7 1.7.1. General 1.7.1.1. This Directive establishes standards of safety which provide an acceptable level of control of the radiation, criticality and thermal hazards to persons, property and the environment that are associated with the carriage of radioactive material. These standards are based on the IAEA Regulations for the Safe Transport of Radioactive Material (ST-1), IAEA, Vienna (1996). Explanatory material on ST-1 can be found in "Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material (1996 Edition)", Safety Standard Series No ST-2, IAEA, Vienna (to be published). 1.7.1.2. The objective of this Directive is to protect persons, property and the environment from the effects of radiation during the transport of radioactive material. This protection is achieved by requiring: (a) Containment of the radioactive contents; (b) Control of external radiation levels; (c) Prevention of criticality; and (d) Prevention of damage caused by heat. These requirements are satisfied firstly by applying a graded approach to contents limits for packages and wagons and to performance standards applied to package designs depending upon the hazard of the radioactive contents. Secondly, they are satisfied by imposing requirements on the design and operation of packages and on the maintenance of packagings, including a consideration of the nature of the radioactive contents. Finally, they are satisfied by requiring administrative controls including, where appropriate, approval by competent authorities. 1.7.1.3. This Directive applies to the transport of radioactive material by rail including transport which is incidental to the use of the radioactive material. Transport comprises all operations and conditions associated with and involved in the movement of radioactive material; these include the design, manufacture, maintenance and repair of packaging, and the preparation, consigning, loading, carriage including in-transit storage, unloading and receipt at the final destination of loads of radioactive material and packages. A graded approach is applied to the performance standards in this Directive that is characterized by three general severity levels: (a) Routine conditions of transport (incident free); (b) Normal conditions of transport (minor mishaps); (c) Accident conditions of transport. 1.7.2. Radiation protection programme 1.7.2.1. The transport of radioactive material shall be subject to a Radiation Protection Programme which shall consist of systematic arrangements aimed at providing adequate consideration of radiation protection measures. 1.7.2.2. The nature and extent of the measures to be employed in the programme shall be related to the magnitude and likelihood of radiation exposures. The programme shall incorporate the requirements in 1.7.2.3, and 1.7.2.4, CV33 (1.1) and (1.4) of 7.5.11 and applicable emergency response procedures. Programme documents shall be available, on request, for inspection by the relevant competent authority. 1.7.2.3. Protection and safety shall be optimised in order that the magnitude of individual doses, the number of persons exposed, and the likelihood of incurring exposure shall be kept as low as reasonably achievable, economic and social factors being taken into account, and doses to persons shall be below the relevant dose limits. A structured and systematic approach shall be adopted and shall include consideration of the interfaces between transport and other activities. 1.7.2.4. For occupational exposures arising from transport activities, where it is assessed that the effective dose: (a) is most unlikely to exceed 1 mSv in a year, no special work patterns, detailed monitoring, dose assessment programmes or individual record keeping shall be required; (b) is likely to be between 1 mSv and 6 mSv in a year, a dose assessment programme via work place monitoring or individual monitoring shall be conducted; (c) is likely to exceed 6 mSv in a year, individual monitoring shall be conducted. When individual monitoring or work place monitoring is conducted, appropriate records shall be kept. 1.7.3. Quality assurance Quality assurance programmes based on international, national or other standards acceptable to the competent authority shall be established and implemented for the design, manufacture, testing, documentation, use, maintenance and inspection of all special form radioactive material, low dispersible radioactive material and packages and for transport and in-transit storage operations to ensure compliance with the relevant requirements of this Directive. Certification that the design specification has been fully implemented shall be available to the competent authority. The manufacturer, consignor or user shall be prepared to provide facilities for competent authority inspection during manufacture and use and to demonstrate to any cognizant competent authority that: (a) the manufacturing methods and materials used are in accordance with the approved design specifications; and (b) all packagings are periodically inspected and, as necessary, repaired and maintained in good condition so that they continue to comply with all relevant requirements and specifications, even after repeated use. Where competent authority approval is required, such approval shall take into account and be contingent upon the adequacy of the quality assurance programme. 1.7.4. Special arrangement 1.7.4.1. Special arrangement shall mean those requirements, approved by the competent authority, according to which consignments which do not satisfy all the requirements of this Directive applicable to radioactive material may be carried. NOTE Special arrangement is not considered to be a temporary derogation in accordance with 1.5.1. 1.7.4.2. Consignments for which conformity with any requirement applicable to Class 7 is impracticable shall not be carried except under special arrangement. Provided the competent authority is satisfied that conformity with the Class 7 requirements of this Directive is impracticable and that the requisite standards of safety established by this Directive have been demonstrated through alternative means the competent authority may approve special arrangement transport operations for single or a planned series of multiple consignments. The overall level of safety in transport shall be at least equivalent to that which would be provided if all the applicable requirements had been met. For international consignments of this type, multilateral approval shall be required. 1.7.5. Radioactive material possessing other dangerous properties In addition to the radioactive and fissile properties, any subsidiary risk of the contents of the package, such as explosiveness, flammability, pyrophoricity, chemical toxicity and corrosiveness, shall also be taken into account in the packing, labelling, marking, placarding, stowage, separation and carriage, in order to be in compliance with all the relevant requirements of this Directive. CHAPTER 1.8 Checks and other support measures to ensure compliance with safety requirements 1.8.1. Administrative controls of dangerous goods 1.8.1.1. The competent authorities of the Member States may, on their national territory, at any time, conduct spot checks to verify whether the requirements concerning the carriage of dangerous goods have been met. These checks shall, however, be made without endangering persons, property or the environment and without major disruption of rail services. 1.8.1.2. Participants in the carriage of dangerous goods (Chapter 1.4) shall, without delay, in the context of their respective obligations, provide the competent authorities and their agents with the necessary information for carrying out the checks. 1.8.1.3. The competent authorities may also, for the purposes of carrying out checks on the premises of the enterprises participating in the carriage of dangerous goods (Chapter 1.4), make inspections, consult the necessary documents and remove samples of dangerous goods or packagings for examination, provided that safety is not jeopardized thereby. The participants in the carriage of dangerous goods (Chapter 1.4) shall also make the wagons or parts of wagons and the equipment and installations accessible for the purpose of checking where this is possible and reasonable. They may, if they deem necessary, designate a person from the enterprise to accompany the representative of the competent authority. 1.8.1.4. If the competent authorities observe that the requirements of this Directive have not been met, they may prohibit a consignment or interrupt a transport operation until the defects observed are rectified, or they may prescribe other appropriate measures. Immobilization may take place on the spot or at another place selected by the authorities for safety reasons. These measures shall not cause a major disruption in rail services. 1.8.2. Mutual administrative support 1.8.2.1. The Member States shall agree on mutual administrative support for the implementation of this Directive. 1.8.2.2. When a Member State has reasons to observe that the safety of the carriage of dangerous goods on its territory is compromised as a result of very serious or repeated infringements by an enterprise which has its headquarters on the territory of another Member State, it shall notify the competent authorities of this Member State of such infringements. The competent authorities of the Member State on the territory of which the very serious or repeated infringements were observed may request the competent authorities of the Member State on the territory of which the enterprise has its headquarters to take appropriate measures against the offender(s). The transmission of data referring to persons shall not be permitted unless it is necessary for the prosecution of very serious or repeated infringements. 1.8.2.3. The authorities notified shall communicate to the competent authorities of the Member State on the territory of which the infringements were observed, the measures which have, if necessary, been taken with respect to the enterprise. 1.8.3. Safety adviser 1.8.3.1. Each undertaking, the activities of which include the transport, or the related loading, unloading, filling or packing of dangerous goods by rail shall appoint one or more safety advisers for the transport of dangerous goods, responsible for helping to prevent the risks inherent in such activities with regard to persons, property and the environment. 1.8.3.2. The competent authorities of the Member States may provide that these requirements shall not apply to undertakings: (a) the activities of which include the carriage of dangerous goods in means of transport belonging to the armed forces or for which the armed forces are responsible, or (b) the activities of which concern quantities in each wagon smaller than those referred to in 1.1.3.1, 2.2.7.1.2 and in Chapters 3.3 and 3.4, or (c) the main or secondary activities of which are not the carriage or the related loading or unloading of dangerous goods but which occasionally engage in the national carriage or the related loading or unloading of dangerous goods posing little danger or risk of pollution. 1.8.3.3. The main task of the adviser shall be, under the responsibility of the head of the undertaking, to seek by all appropriate means and by all appropriate action, within the limits of the relevant activities of that undertaking, to facilitate the conduct of those activities in accordance with the requirements applicable and in the safest possible way. With regard to the undertaking's activities, the adviser has the following duties in particular: - monitoring compliance with the requirements governing the transport of dangerous goods; - advising his undertaking on the transport of dangerous goods; - preparing an annual report to the management of his undertaking or a local public authority, as appropriate, on the undertaking's activities in the transport of dangerous goods. Such annual reports shall be preserved for five years and made available to the national authorities at their request. The adviser's duties also include monitoring the following practices and procedures relating to the relevant activities of the undertaking: - the procedures for compliance with the requirements governing the identification of dangerous goods being carried; - the undertaking's practice in taking account, when purchasing means of transport, of any special requirements in connection with the dangerous goods being transported; - the procedures for checking the equipment used in connection with the transport, loading or unloading of dangerous goods; - the proper training of the undertaking's employees and the maintenance of records of such training; - the implementation of proper emergency procedures in the event of any accident or incident that may affect safety during the transport, loading or unloading of dangerous goods; - investigating and, where appropriate, preparing reports on serious accidents, incidents or serious infringements recorded during the transport, loading or unloading of dangerous goods; - the implementation of appropriate measures to avoid the recurrence of accidents, incidents or serious infringements; - the account taken of the legal requirements and special requirements associated with the transport of dangerous goods in the choice and use of sub-contractors or third parties; - verification that employees involved in the transport, loading or unloading of dangerous goods have detailed operational procedures and instructions, - the introduction of measures to increase awareness of the risks inherent in the transport, loading and unloading of dangerous goods; - the implementation of verification procedures to ensure the presence on board means of transport of the documents and safety equipment which must accompany transport and the compliance of such documents and equipment with the regulations; - the implementation of verification procedures to ensure compliance with the requirements governing loading and unloading. 1.8.3.4. The adviser may also be the head of the undertaking, a person with other duties in the undertaking, or a person not directly employed by that undertaking, provided that that person is capable of performing the duties of adviser. 1.8.3.5. Each undertaking concerned shall, on request, inform the competent authority or the body designated for that purpose by each Member State of the identity of its adviser. 1.8.3.6. Whenever an accident affects persons, property or the environment or results in damage to property or the environment during transport, loading or unloading carried out by the undertaking concerned, the adviser shall, after collecting all the relevant information, prepare an accident report to the management of the undertaking or to a local public authority, as appropriate. That report shall not replace any report by the management of the undertaking which might be required under any other international or national legislation. 1.8.3.7. An adviser shall hold a vocational training certificate, valid for transport by rail. That certificate shall be issued by the competent authority or the body designated for that purpose by each Member State. 1.8.3.8. To obtain a certificate, a candidate shall undergo training and pass an examination approved by the competent authority of the Member State. 1.8.3.9. The main aims of the training shall be to provide candidates with sufficient knowledge of the risks inherent in the transport of dangerous goods, of the legal and administrative requirements and of the duties listed in 1.8.3.3. 1.8.3.10. The examination shall be organized by the competent authority or by an examining body designated by the competent authority. The examining body shall be designated in writing. This approval may be of limited duration and shall be based on the following criteria: - competence of the examining body; - specifications of the form of the examinations the examining body is proposing; - measures intended to ensure that examinations are impartial; - independence of the body from all natural or legal persons employing safety advisers. 1.8.3.11. The aim of the examination is to ascertain whether candidates possess the necessary level of knowledge to carry out the duties incumbent upon a safety adviser as listed in 1.8.3.3, for the purpose of obtaining the certificate prescribed in 1.8.3.7, and it shall cover at least the following subjects: (a) knowledge of the types of consequences which may be caused by an accident involving dangerous goods and knowledge of the main causes of accidents; (b) requirements under national law, international conventions and agreements, with regard to the following in particular: - classification of dangerous goods (procedure for classifying solutions and mixtures, structure of the list of substances, classes of dangerous goods and principles for their classification, nature of dangerous goods carried, physical, chemical and toxicological properties of dangerous goods); - general packing requirements, requirements for tanks and tank-containers (types, code, marking, construction, initial and periodic testing); - marking, labelling, placarding and orange plates (marking and labelling of packages, placing and removal of placards and orange plates); - information in the consignment note [necessary information]; - method of consignment and restrictions on forwarding (wagon load, full wagon load, carriage in bulk, carriage in IBCs, carriage in containers; carriage in fixed or demountable tanks); - carriage of passengers; - prohibitions and precautions relating to mixed loading; - segregation of goods; - limited and exempted quantities; - handling and stowage (loading and unloading, degree of filling, stowage and segregation); - cleaning and/or degassing before loading and after unloading; - crews, vocational training; - documents to be carried on board (consignment note, copies of any derogations, other documents); - operational and accidental discharges of pollutants; - requirements relating to transport equipment. 1.8.3.12.

Member States shall lay down uniform conditions for the measures referred to in 1.9.1 and for those concerning communications with the States, carriers and railway infrastructure managers. Part 2 CLASSIFICATION CHAPTER 2.1 General requirements 2.1.1. Introduction 2.1.1.1. The classes of dangerous goods according to this Directive are the following: Class 1 Explosive substances and articles Class 2 Gases Class 3 Flammable liquids Class 4.1 Flammable solids, self-reactive substances and solid desensitized explosives Class 4.2 Substances liable to spontaneous combustion Class 4.3 Substances which, in contact with water, emit flammable gases Class 5.1 Oxidizing substances Class 5.2 Organic peroxides Class 6.1 Toxic substances Class 6.2 Infectious substances Class 7 Radioactive material Class 8 Corrosive substances Class 9 Miscellaneous dangerous substances and articles 2.1.1.2. Each entry in the different classes has been assigned a UN number. The following types of entries are used: A. Single entries for well defined substances or articles including entries for substances covering several isomers, e.g.: UN No 1090 ACETON UN No 1104 AMYL ACETATES UN No 1194 ETHYL NITRITE SOLUTION B. Generic entries for a well defined group of substances or articles, which are not n.o.s. entries, e.g.: UN No 1133 ADHESIVES UN No 1266 PERFUMERY PRODUCTS UN No 2757 CARBAMATE PESTICIDE, SOLID, TOXIC UN No 3101 ORGANIC PEROXIDE TYPE B, LIQUID C. Specific n.o.s. entries covering a group of substances or articles of a particular chemical or technical nature, not otherwise specified, e.g.: UN No 1477 NITRATES, INORGANIC, N.O.S. UN No 1987 ALCOHOLS, N.O.S. D. General n.o.s. entries covering a group of substances or articles having one or more dangerous properties, not otherwise specified, e.g.: UN No 1325 FLAMMABLE SOLID, ORGANIC, N.O.S. UN No 1993 FLAMMABLE LIQUID, N.O.S. The entries defined under B, C and D are defined as collective entries. 2.1.1.3. For packing purposes, certain substances may be assigned to packing groups in accordance with their degree of danger. The packing groups have the following meanings: Packing group I: Substances presenting high danger Packing group II: Substances presenting medium danger Packing group III: Substances presenting low danger 2.1.2. Principles of classification 2.1.2.1. The dangerous goods covered by the heading of a class are defined on the basis of their properties according to sub-section 2.2.x.1 of the relevant class. Assignment of dangerous goods to a class and a packing group is made according to the criteria mentioned in the same sub-section 2.2.x.1. Assignment of one or several subsidiary risk(s) to a dangerous substance or article is made according to the criteria of the class or classes corresponding to those risks, as mentioned in the appropriate sub-section(s) 2.2.x.1. 2.1.2.2. All dangerous goods entries are listed in table A of Chapter 3.2 in the numerical order of their UN Number. This table contains relevant information on the goods listed, such as name, class, packing group(s), label(s) to be affixed, packing and carriage requirements. NOTE: An alphabetical list of these entries is given in table B of Chapter 3.2. 2.1.2.3. Dangerous goods which are listed or defined in sub-section 2.2.x.2 of each class are not to be accepted for carriage. 2.1.2.4. Goods not mentioned by name, i.e. goods not listed as single entries in table A of Chapter 3.2 and not listed or defined in one of the above-mentioned sub-sections 2.2.x.2 shall be assigned to the relevant class in accordance with the procedure in 2.1.3. In addition, the subsidiary risk (if any) and the packing group (if any) shall be determined. Once the class, subsidiary risk (if any) and packing group (if any) have been established the relevant UN number shall be determined. The decision trees in sub-sections 2.2.x.3 (list of collective entries) at the end of each class indicate the relevant parameters for selecting the relevant collective entry (UN number). In all cases the most specific collective entry covering the properties of the substance or article shall be selected, according to the hierarchy indicated in 2.1.1.2 by the letters B, C and D respectively. If the substance or article cannot be classified under entries of type B or C according to 2.1.1.2, then, and only then shall it be classified under an entry of type D. 2.1.2.5. On the basis of the test procedures of Chapter 2.3 and the criteria set out in sub-sections 2.2.x.1 of classes when it is so specified, it may be determined that a substance, solution or mixture of a certain class, mentioned by name in Table A of Chapter 3.2, does not meet the criteria of that class. In such a case, the substance, solution or mixture is deemed not to belong to that class. 2.1.2.6. For the purposes of classification, substances with a melting point or initial melting point of 20 °C or lower at a pressure of 101,3 kPa shall be considered to be liquids. A viscous substance for which a specific melting point cannot be determined shall be subjected to the ASTM D 4359-90 test or to the test for determining fluidity (penetrometer test) prescribed in 2.3.4. 2.1.3. Classification of substances, including solutions and mixtures (such as preparations and wastes), not mentioned by name 2.1.3.1. Substances, including solutions and mixtures, not mentioned by name shall be classified according to their degree of danger on the basis of the criteria mentioned in sub-section 2.2.x.1 of the various classes. The danger(s) presented by a substance shall be determined on the basis of its physical and chemical characteristics and physiological properties. Such characteristics and properties shall also be taken into account when such experience leads to a more stringent assignment. 2.1.3.2. A substance not mentioned by name in table A of Chapter 3.2 presenting a single hazard shall be classified in the relevant class under a collective entry listed in sub-section 2.2.x.3 of that class. 2.1.3.3. A solution or mixture containing only one dangerous substance mentioned by name in table A of Chapter 3.2, together with one or more non-dangerous substance(s), shall be regarded as the dangerous substance listed by name, unless: (a) the solution or mixture is specifically mentioned by name in table A of Chapter 3.2; or (b) it is quite clear from the entry for the dangerous substance that it is applicable only to the pure or technically pure substance; or (c) the class, physical state or packing group of the solution or mixture is different from that of the dangerous substance. In the case of (b) or (c), the solution or mixture shall be classified as a substance mentioned by name in the relevant class under a collective entry according to sub-section 2.2.x.3 of that class, taking account of any subsidiary risks, unless the substance or mixture does not meet the criteria of a particular class and is not therefore subject to the requirements of this Directive. 2.1.3.4. Solutions and mixtures containing one of the following substances mentioned by name shall always be classified under the same entry as the substance they contain, provided they do not have the hazard characteristics as indicated in 2.1.3.5: - Class 3 UN No 1921 PROPYLENEIMINE, INHIBITED; UN No 2481 ETHYLISOCYANATE; UN No 3064 NITROGLYCERIN SOLUTION IN ALCOHOL with more than 1 % but not more than 5 % nitroglycerin - Class 6.1 UN No 1051 HYDROGEN CYANIDE, STABILIZED, containing less than 3 % water; UN No 1185 ETHYLENEIMINE, INHIBITED; UN No 1259 NICKEL CARBONYL; UN No 1613 HYDROGEN CYANIDE, AQUEOUS SOLUTION (hydrocyanic acid), with not more than 20 % hydrogen cyanide; UN No 1614 HYDROGEN CYANIDE, STABILIZED, containing not more than 3 % water and absorbed in a porous inert material; UN No 1994 PENTACARBONYL; UN No 2480 METHYL ISOCYANATE; UN No 3294 HYDROGEN CYANIDE, SOLUTION IN ALCOHOL, with not more than 45 % hydrogen cyanide - Class 8 UN No 1052 HYDROGEN FLUORIDE, ANHYDROUS; UN No 1744 BROMINE or UN No 1744 BROMINE SOLUTION; UN No 1790 HYDROFLUORIC ACID with more than 85 % hydrogen fluoride; UN No 2576 PHOSPHORUS OXYBROMIDE, MOLTEN - Class 9 UN No 2315 POLYCHLORINATED BIPHENYLS; UN No 3151 POLYHALOGENATED BIPHENYLS, LIQUID or UN No 3151 POLYHALOGENATED TERPHENYLS, LIQUID; UN No 3152 POLYHALOGENATED BIPHENYLS, SOLID or UN No 3152 POLYHALOGENATED TERPHENYLS, SOLID, unless they contain one of the substances of Class 3 or Class 6.1 or Class 8 listed above; in which case they shall be classified accordingly. 2.1.3.5. Substances not mentioned by name in table A of Chapter 3.2, having more than one hazard characteristic and solutions or mixtures containing several dangerous substances shall be classified under a collective entry (see 2.1.2.4) and packing group of the appropriate class in accordance with their hazard characteristics. Such classification according to the hazard characteristics shall be carried out as follows: 2.1.3.5.1. The physical and chemical characteristics and physiological properties shall be determined by measurement or calculation and the substance, solution or mixture shall be classified according to the criteria mentioned in sub-section 2.2.x.1 of the various classes. 2.1.3.5.2. If this determination is not possible without disproportionate cost or effort (as for some kinds of wastes), the substance, solution or mixture shall be classified in the class of the component presenting the major hazard. 2.1.3.5.3. If the hazard characteristics of the substance, solution or mixture fall within more than one class or group of substances listed below then the substance, solution or mixture shall be classified in the class or group of substances corresponding to the major hazard on the basis of the following order of precedence: (a) Material of Class 7 (apart from radioactive material in excepted packages where the other hazardous properties take precedence); (b) Substances of Class 1; (c) Substances of Class 2; (d) Liquid desensitized explosives of Class 3; (e) Self-reactive substances and solid desensitized explosives of Class 4.1; (f) Pyrophoric substances of Class 4.2; (g) Substances of Class 5.2; (h) Substances of Class 6.1 or Class 3 which, on the basis of their inhalation toxicity, are to be classified under Packing group I (substances meeting the classification criteria of Class 8 and having an inhalation toxicity of dust and mist (LC50) in the range of Packing group I and a toxicity through oral ingestion or dermal contact only in the range of Packing group III or less, shall be allocated to Class 8); (i) Infectious substances of Class 6.2. 2.1.3.5.4. If the hazard characteristics of the substance fall within more than one class or group of substances not listed in 2.1.3.5.3 above, the substance shall be classified in accordance with the same procedure but the relevant class shall be selected according to the precedence of hazards table in 2.1.3.9. 2.1.3.6. The most specific applicable generic entry (see 2.1.2.4) shall always be used, i.e. a general n.o.s. entry shall only be used if a generic entry or a specific n.o.s. entry cannot be used. 2.1.3.7. Solutions and mixtures of oxidizing substances or substances with an oxidizing subsidiary risk may have explosive properties. In such a case they are not to be accepted for carriage unless they meet the requirements for Class 1. 2.1.3.8. For the purposes of this Directive, substances, solutions and mixtures (such as preparations and wastes) which cannot be assigned to Classes 1 to 8 or Class 9 entries other than UN Nos 3077 and 3082, but which may be assigned to UN Nos 3077 or 3082 on the basis of the test methods and criteria of section 2.3.5 shall be considered to be pollutant to the aquatic environment. Solutions and mixtures (such as preparations and wastes) for which no data conforming to the classification criteria are available shall be considered to be pollutant to the aquatic environment if the LC50 (see definitions in 2.3.5.1, 2.3.5.2 and 2.3.5.3) evaluated according to the following formula: >PIC FILE= "L_2004121EN.003901.TIF"> is equal to or lower than: (a) 1 mg/l; or (b) 10 mg/l if the pollutant is not readily biodegradable or, being biodegradable, has a log Pow >= 3,0 (see also 2.3.5.6) 2.1.3.9. Precedence of hazards table >TABLE> SOL = Solids and mixtures LIQ = Liquids, mixtures and solutions DERMAL = Dermal toxicity ORAL = Oral toxicity INHAL = Inhalation toxicity NOTE: 1. Examples to explain the use of the table Classification of a single substance Description of the substance to be classified: An amine not mentioned by name meeting the criteria for Class 3, packing group II as well as those for Class 8, packing group I. Procedure: The intersection of line 3 II with column 8 I gives 8 I. This amine has therefore to be classified in Class 8 under: UN No 2734 AMINES LIQUID, CORROSIVE, FLAMMABLE, N.O.S. or UN No 2734 POLYAMINES, LIQUID, CORROSIVE, FLAMMABLE, N.O.S. packing group I Classification of a mixture Description of the mixture to be classified: Mixture consisting of a flammable liquid classified in Class 3, packing group III, a toxic substance in Class 6.1, packing group II and a corrosive substance in Class 8, packing group I. Procedure: The intersection of line 3 III with column 6.1 II gives 6.1 II. The intersection of line 6.1 II with column 8 I LIQ gives 8 I. This mixture has therefore to be classified in Class 8 under: UN No 2922 CORROSIVE LIQUID, TOXIC, N.O.S. packing group I. 2. Examples for the classification of mixtures and solutions under a class and a packing group: A phenol solution of Class 6.1, (II), in benzene of Class 3, (II) is to be classified in Class 3, (II); this solution is to be classified under UN No 1992 FLAMMABLE LIQUID, TOXIC, N.O.S., Class 3, (II), by virtue of the toxicity of the phenol.

The heading of Class 1 covers: (a) Explosive substances: solid or liquid substances (or mixtures of substances) capable by chemical reaction of producing gases at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances: substances or mixtures of substances designed to produce an effect by heat, light, sound, gas or smoke or a combination of these as the result of non-detonating self-sustaining exothermic chemical reactions. NOTES: 1. Substances which are not themselves explosive but which may form an explosive mixture of gas, vapour or dust are not substances of Class 1. 2. Also excluded from Class 1 are: water- or alcohol-wetted explosives of which the water or alcohol content exceeds the limits specified and those containing plasticizers - these explosives are assigned to Class 3 or Class 4.1 - and those explosives which, on the basis of their predominant hazard, are assigned to Class 5.2. (b) Explosive articles: articles containing one or more explosive substances or pyrotechnic substances. NOTE: Devices containing explosive or pyrotechnic substances in such small quantity or of such a character that their inadvertent or accidental ignition or initiation during carriage would not cause any manifestation external to the device by projection, fire, smoke, heat or loud noise are not subject to the requirements of Class 1. (c) Substances and articles not mentioned above which are manufactured with a view to producing a practical effect by explosion or a pyrotechnic effect. 2.2.1.1.2. Any substance or article having or suspected of having explosive properties shall be considered for assignment to Class 1 in accordance with the tests, procedures and criteria prescribed in Part I, Manual of Tests and Criteria. A substance or article assigned to Class 1 can only be accepted for carriage when it has been assigned to a name or n.o.s. entry listed in table A of Chapter 3.2 and meets the criteria of the Manual of Tests and Criteria. 2.2.1.1.3. The substances and articles of Class 1 shall be assigned to a UN Number and a name or n.o.s. entry listed in table A of Chapter 3.2. Interpretation of the names of substances and articles in table A of Chapter 3.2 shall be based upon the glossary in 2.2.1.1.7. Samples of new or existing explosive substances or articles carried for purposes including: testing, classification, research and development quality control, or as a commercial sample, other than initiating explosive, may be assigned to UN No 0190 SAMPLES, EXPLOSIVE. The assignment of substances and articles not mentioned by name as such in table A of Chapter 3.2 to an n.o.s. entry or UN No 0190 SAMPLES, EXPLOSIVE as well as the assignment of certain substances the carriage of which is subject to a specific authorization by the competent authority according to the special requirements referred to in column (6) of table A of Chapter 3.2 shall be made by the competent authority of the country of origin.

The compatibility group shall be determined in accordance with the definitions in 2.2.1.1.6. The classification code shall consist of the division number and the compatibility group letter. 2.2.1.1.5. Definition of divisions >TABLE> NOTE: The risk from articles of Division 1.6 is limited to the explosion of a single article. 2.2.1.1.6. Definition of compatibility groups of substances and articles >TABLE> NOTES: 1. Each substance or article, packed in a specified packaging, may be assigned to one compatibility group only. Since the criterion of compatibility group S is empirical, assignment to this group is necessarily linked to the tests for assignment of a classification code. 2. Articles of compatibility groups D and E may be fitted or packed together with their own means of initiation provided that such means have at least two effective protective features designed to prevent an explosion in the event of accidental functioning of the means of initiation. Such packages shall be assigned to compatibility groups D or E. 3. Articles of compatibility groups D and E may be packed together with their own means of initiation, which do not have two effective protective features (i.e. means of initiation assigned to compatibility group B), provided that they comply with mixed packing provision MP 21 of section 4.1.10. Such packages shall be assigned to compatibility groups D or E. 4. Articles may be fitted or packed together with their own means of ignition provided that the means of ignition cannot function during normal conditions of carriage. 5. Articles of compatibility groups C, D and E may be packed together. Such packages shall be assigned to compatibility group E. 2.2.1.1.7. Glossary of names NOTES: 1. The descriptions in the glossary are not intended to replace the test procedures, nor to determine the hazard classification of a substance or article of Class 1.

Criteria 2.2.2.1.1. The heading of Class 2 covers pure gases, mixtures of gases, mixtures of one or more gases with one or more other substances and articles containing such substances. A gas is a substance which: (a) at 50 °C has a vapour pressure greater than 300 kPa (3 bar); or (b) is completely gaseous at 20 °C at the standard pressure of 101,3 kPa. NOTES: 1. UN No 1052 HYDROGEN FLUORIDE is nevertheless classified in Class 8. 2. A pure gas may contain other components deriving from its production process or added to preserve the stability of the product, provided that the level of these components does not change its classification or its conditions of carriage, such as filling ratio, filling pressure, test pressure. 3. N.O.S. entries in 2.2.2.3 may cover pure gases as well as mixtures. 2.2.2.1.2. The substances and articles of Class 2 are subdivided as follows: 1. Compressed gases: gases having a critical temperature below 20 °C; 2. Liquefied gases: gases having a critical temperature of 20 °C or above; 3. Refrigerated liquefied gases: gases which when carried are partially liquid because of their low temperature; 4. Gases dissolved under pressure: gases which when carried are dissolved in a solvent; 5. Aerosol dispensers and receptacles, small, containing gas (gas cartridges); 6. Other articles containing gas under pressure; 7. Non-pressurized gases subject to special requirements (gas samples). 2.2.2.1.3. Substances and articles of Class 2, classified under an entry in 2.2.2.3 are assigned to one of the following groups according to their hazardous properties, as follows: >TABLE> For gases and gas mixtures presenting hazardous properties associated with more than one group according to the criteria, the groups designated by letter T take precedence over all other groups. The groups designated by letter F take precedence over the groups designated by letters A or O. NOTES: 1. In the UN Model Regulations, the IMDG Code and the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air, gases are assigned to one of the following three divisions, based on the primary hazard: Division 2.1: flammable gases (corresponding to the groups designated by the capital letter F); Division 2.2: non-flammable, non-toxic gases (corresponding to the groups designated by the capital letters A or O); Division 2.3: toxic gases (corresponding to the groups designated by the capital letter T (i.e. T, TF, TC, TO, TFC and TOC). 2. Aerosols and receptacles, small, containing gas shall be assigned, according to the hazard of the contents, to the letters A to TOC. The contents are considered to be flammable if they include more than 45 % by mass, or more than 250 g, of flammable components. Flammable components are gases which are flammable in air at normal pressure or substances or preparations in liquid form which have a flash-point less than or equal to 100 °C. 3. Corrosive gases are considered to be toxic, and are therefore assigned to the group TC, TFC or TOC. 4. Mixtures containing more than 21 % oxygen by volume shall be classified as oxidizing. 2.2.2.1.4. If a mixture of Class 2 mentioned by name in table A of Chapter 3.2 meets different criteria as mentioned in 2.2.2.1.2 and 2.2.2.1.5, this mixture shall be classified according to the criteria and assigned to an appropriate N.O.S. entry. 2.2.2.1.5. Substances and articles of Class 2 which are not mentioned by name in table A of Chapter 3.2 shall be classified under a collective entry listed in 2.2.2.3 in accordance with 2.2.2.1.2 and 2.2.2.1.3. The following criteria shall apply: Asphyxiant gases Gases which are non-oxidizing, non-flammable and non-toxic and which dilute or replace oxygen normally in the atmosphere. Flammable gases Gases which at 20 °C and a standard pressure of 101,3 kPa: (a) are ignitable when in a mixture of 13 % or less by volume with air; or (b) have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit. Flammability shall be determined by tests or by calculation, in accordance with methods adopted by ISO (see ISO 10156:1996). Where insufficient data are available to use these methods, tests by a comparable method recognized by the competent authority of the country of origin may be used. If the country of origin is not a COTIF Member State these methods shall be recognized by the competent authority of the first COTIF Member State reached by the consignment. Oxidizing gases Gases, which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does. Oxidizing ability is determined either by tests or by calculation methods adopted by ISO (see ISO 10156:1996). Toxic gases NOTE: Gases meeting the criteria for toxicity in part or completely owing to their corrosivity are to be classified as toxic. See also the criteria under the heading "Corrosive gases" for a possible subsidiary corrosivity risk. Gases which: (a) are known to be so toxic or corrosive to humans as to pose a hazard to health; or (b) are presumed to be toxic or corrosive to humans because they have a LC50 value for acute toxicity equal to or less than 5000 ml/m3 (ppm) when tested in accordance with 2.2.61.1. In the case of gas mixtures (including vapours of substances from other classes) the following formula may be used: >PIC FILE= "L_2004121EN.006101.TIF"> where fi= mole fraction of the ith component substance of the mixture; Ti= toxicity index of the ith component substance of the mixture; The Ti equals the LC50 value as found in ISO 10298:1995. When no LC50 value is listed in ISO 10298:1995, a LC50 value available in scientific literature shall be used. When the LC50 value is unknown, the toxicity index is determined by using the lowest LC50 value of substances of similar physiological and chemical effects, or through testing if this is the only practical possibility. Corrosive gases Gases or gas mixtures meeting the criteria for toxicity completely owing to their corrosivity shall be classified as toxic with a subsidiary corrosivity risk. A gas mixture that is considered to be toxic due to the combined effects of corrosivity and toxicity has a subsidiary risk of corrosivity when the mixture is known by human experience to be destructive to the skin, eyes or mucous membranes or when the LC50 value of the corrosive components of the mixture is equal to or less than 5000 ml/m3 (ppm) when the LC50 is calculated by the formula: >PIC FILE= "L_2004121EN.006102.TIF"> where fci= mole fraction of the ith corrosive component substance of the mixture; Tci= toxicity index of the ith corrosive component substance of the mixture; The Tci equals the LC50 value as found in ISO10298:1995. When no LC50 value is listed in ISO 10298:1995, a LC50 value available in scientific literature shall be used. When the LC50 value is unknown the toxicity index is determined by using the lowest LC50 value of substances of similar physiological and chemical effects, or through testing if this is the only practical possibility. 2.2.2.2. Gases not accepted for carriage 2.2.2.2.1. Chemically unstable substances of Class 2 shall not be accepted for carriage, unless the necessary steps have been taken to prevent all possibility of a dangerous reaction e.g. decomposition, dismutation or polymerisation under normal conditions of transport. To this end particular care shall be taken to ensure that receptacles and tanks do not contain any substances liable to promote these reactions. 2.2.2.2.2. The following substances and mixtures shall not be accepted for carriage: - UN No 2186 HYDROGEN CHLORIDE, REFRIGERATED LIQUID; - UN No 2421 NITROGEN TRIOXIDE; - UN No 2455 METHYL NITRITE; - Refrigerated liquefied gases which cannot be assigned to classification codes 3A, 3O or 3F; - Gases dissolved under pressure which cannot be classified under UN Nos 1001, 2073 or 3318. 2.2.2.3.

Criteria 2.2.41.1.1. The heading of Class 4.1 covers flammable substances and articles, desensitized explosives which are solids according to subparagraph (a) of the definition "solid" in 1.2.1 and selfreactive solids or liquids. The following are assigned to Class 4.1: - readily flammable solid substances and articles (see 2.2.41.1.3 to 2.2.41.1.8); - self-reactive solids or liquids (see 2.2.41.1.9 to 2.2.41.1.16); - solid desensitized explosives (see 2.2.41.1.18); - substances related to self-reactive substances (see 2.2.41.1.19). 2.2.41.1.2. The substances and articles of Class 4.1 are subdivided as follows: >TABLE> Flammable solids Definition and properties 2.2.41.1.3. Flammable solids are readily combustible solids and solids which may cause fire through friction. Readily combustible solids are powdered, granular, or pasty substances which are dangerous if they can be easily ignited by brief contact with an ignition source, such as a burning match, and if the flame spreads rapidly. The danger may come not only from the fire but also from toxic combustion products. Metal powders are especially dangerous because of the difficulty of extinguishing a fire since normal extinguishing agents such as carbon dioxide or water can increase the hazard. Classification 2.2.41.1.4. Substances and articles classified as flammable solids of Class 4.1 are listed in table A of Chapter 3.2. The assignment of organic substances and articles not mentioned by name in table A of Chapter 3.2 to the relevant entry of sub-section 2.2.41.3 in accordance with the requirements of Chapter 2.1 can be based on experience or on the results of the test procedures in accordance with Part III, sub-section 33.2.1 of the Manual of Tests and Criteria. The assignment of inorganic substances not mentioned by name shall be based on the results of the test procedures in accordance with Part III, sub-section 33.2.1 of the Manual of Tests and Criteria; experience shall also be taken into account when it leads to a more stringent assignment. 2.2.41.1.5. When substances not mentioned by name are assigned to one of the entries listed in 2.2.41.3 on the basis of the test procedures in accordance with the Manual of Tests and Criteria, Part III, sub-section 33.2.1, the following criteria apply: (a) With the exception of metal powders or powders of metal alloys, powdery, granular or pasty substances shall be classified as readily flammable substances of Class 4.1 if they can be easily ignited by brief contact with an ignition source (e.g. a burning match), or if, in the event of ignition, the flame spreads rapidly, the burning time is less than 45 seconds for a measured distance of 100 mm or the rate of burning is greater than 2,2 mm/s. (b) Metal powders or powders of metal alloys shall be assigned to Class 4.1 if they can be ignited by a flame and the reaction spreads over the whole length of the sample in 10 minutes or less.

On the basis of the test procedure in accordance with the Manual of Tests and Criteria, Part III, Section 33.2.1 and the criteria set out in 2.2.41.1.4 and 2.2.41.1.5, it may also be determined whether the nature of a substance mentioned by name is such that the substance is not subject to the requirements for this Class. 2.2.41.1.7. If substances of Class 4.1, as a result of admixtures, come into different categories of risk from those to which the substances mentioned by name in table A of Chapter 3.2 belong, these mixtures shall be assigned to the entries to which they belong on the basis of their actual degree of danger. NOTE: For the classification of solutions and mixtures (such as preparations and wastes) see also 2.1.3. Assignment of packing groups 2.2.41.1.8. Flammable solids classified under the various entries in table A of Chapter 3.2 shall be assigned to packing groups II or III on the basis of test procedures of the Manual of Tests and Criteria, Part III, sub-section 33.2.1, in accordance with the following criteria: (a) Readily flammable solids which, when tested, have a burning time of less than 45 seconds over a measured distance of 100 mm shall be assigned to: Packing group II: if the flame passes the wetted zone; Packing group III: if the wetted zone stops the flame for at least four minutes; (b) Metal powders or powders of metal alloys shall be assigned to: Packing group II: if, when tested, the reaction spreads over the whole length of the sample in five minutes or less; Packing group III: if, when tested, the reaction spreads over the whole length of the sample in more than five minutes. For solids which may cause fire through friction, the packing group shall be assigned by analogy with existing entries or in accordance with any special requirement. Self-reactive substances Definitions 2.2.41.1.9. For the purposes of this Directive, self-reactive substances are thermally unstable substances liable to undergo a strongly exothermic decomposition even without participation of oxygen (air). Substances are not considered to be self-reactive substances of Class 4.1, if: (a) they are explosives according to the criteria of Class 1; (b) they are oxidizing substances according to the assignment procedure of Class 5.1 (see 2.2.51.1); (c) they are organic peroxides according to the criteria of Class 5.2 (see 2.2.52.1); (d) their heat of decomposition is less than 300 J/g; or (e) their self-accelerating decomposition temperature (SADT) (see Note 2 below) is greater than 75 °C for a 50 kg package. NOTES: 1. The heat of decomposition can be determined using any internationally recognised method e.g. differential scanning calorimetry and adiabatic calorimetry. 2. The self-accelerating decomposition temperature (SADT) is the lowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used during carriage. Requirements for the determination of the SADT are given in the Manual of Tests and Criteria, Part II, Chapter 20 and section 28.4. 3. Any substance which shows the properties of a self-reactive substance shall be classified as such, even if this substance gives a positive test result according to 2.2.42.1.5 for classification in Class 4.2. Properties 2.2.41.1.10. The decomposition of self-reactive substances can be initiated by heat, contact with catalytic impurities (e.g. acids, heavy-metal compounds, bases), friction or impact. The rate of decomposition increases with temperature and varies with the substance. Decomposition, particularly if no ignition occurs, may result in the evolution of toxic gases or vapours. For certain self-reactive substances, the temperature shall be controlled. Some self-reactive substances may decompose explosively, particularly if confined. This characteristic may be modified by the addition of diluents or by the use of appropriate packagings. Certain self-reactive substances burn vigorously. Self-reactive substances are, for example, some compounds of the types listed below: - aliphatic azo compounds (-C-N=N-C-); - organic azides (-C-N3); - diazonium salts (-CN2+Z-); - N-nitroso compounds (-N-N=O); - aromatic sulphohydrazides (-SO2-NH-NH2). This list is not exhaustive and substances with other reactive groups and some mixtures of substances may have similar properties. Classification 2.2.41.1.11. Self-reactive substances are classified into seven types according to the degree of danger they present. The types of self-reactive substances range from type A, which is not accepted for carriage in the packaging in which it is tested, to type G, which is not subject to the requirements for self-reactive substances of Class 4.1. The classification of types B to F is directly related to the maximum quantity allowed in one packaging. The principles to be applied for classification as well as the applicable classification procedures, test methods and criteria and an example of a suitable test report are given in Part II of the Manual of Tests and Criteria. 2.2.41.1.12. Substances which have already been classified and assigned to the appropriate collective entry are listed in 2.2.41.4 together with the applicable UN number and packing method. The collective entries specify: - self-reactive substances types B to F, see 2.2.41.1.11 above; - physical state (liquid/solid). The classification of the self-reactive substances listed in 2.2.41.4 is based on the technically pure substance (except where a concentration of less than 100 % is specified). 2.2.41.1.13. Classification of self-reactive substances or formulations of self-reactive substances not listed in 2.2.41.4 and assignment to a collective entry shall be made by the competent authority of the country of origin on the basis of a test report. The statement of approval shall contain the classification and the relevant transport conditions. If the country of origin is not a COTIF Member State, the classification and the conditions of carriage shall be recognized by the competent authority of the first COTIF Member State reached by the consignment. 2.2.41.1.14. Activators, such as zinc compounds, may be added to some self-reactive substances to change their reactivity. Depending on both the type and the concentration of the activator, this may result in a decrease in thermal stability and a change in explosive properties. If either of these properties is altered, the new formulation shall be assessed in accordance with the classification procedure. 2.2.41.1.15. Samples of self-reactive substances or formulations of self-reactive substances not listed in 2.2.41.4, for which a complete set of test results is not available and which are to be carried for further testing or evaluation, shall be assigned to one of the appropriate entries for self-reactive substances type C provided the following conditions are met: - the available data indicates that the sample would be no more dangerous than self-reactive substances type B; - the sample is packaged in accordance with packing method OP2 and the quantity per wagon is limited to 10 kg; Samples requiring temperature control shall not be accepted for carriage by rail. Desensitization 2.2.41.1.16. In order to ensure safety during carriage, self-reactive substances are in many cases desensitized by use of a diluent. Where a percentage of a substance is stipulated, this refers to the percentage by mass, rounded to the nearest whole number. If a diluent is used, the self-reactive substance shall be tested with the diluent present in the concentration and form used in carriage. Diluents which may allow a self-reactive substance to concentrate to a dangerous extent in the event of leakage from a packaging shall not be used. Any diluent shall be compatible with the self-reactive substance. In this regard, compatible diluents are those solids or liquids which have no detrimental influence on the thermal stability and hazard type of the self-reactive substance. 2.2.41.1.17. (reserved) Solid desensitized explosives 2.2.41.1.18. Solid desensitized explosives are substances which are wetted with water or alcohols or are diluted with other substances to suppress their explosive properties. Such entries in table A of Chapter 3.2 are: UN Nos 1310, 1320, 1321, 1322, 1336, 1337, 1344, 1347, 1348, 1349, 1354, 1355, 1356, 1357, 1517, 1571, 2555, 2556, 2557, 2852, 2907, 3317, 3319 and 3344; and, if special requirement 15 of Chapter 3.3 is complied with: UN Nos 0154, 0155, 0209, 0214, 0215 and 0234; and, if special requirement 18 of Chapter 3.3. is complied with: UN No 0220.

Criteria 2.2.42.1.1. The heading of Class 4.2 covers: - Pyrophoric substances which are substances, including mixtures and solutions (liquid or solid), which even in small quantities ignite on contact with air within five minutes. These are the Class 4.2 substances the most liable to spontaneous combustion; and - Self-heating substances and articles which are substances and articles, including mixtures and solutions, which, on contact with air, without energy supply, are liable to self-heating. These substances will ignite only in large amounts (kilogrammes) and after long periods of time (hours or days). 2.2.42.1.2. The substances and articles of Class 4.2 are subdivided as follows: >TABLE> Properties 2.2.42.1.3. Self-heating of these substances, leading to spontaneous combustion, is caused by reaction of the substance with oxygen (in the air) and the heat developed not being conducted away rapidly enough to the surroundings. Spontaneous combustion occurs when the rate of heat production exceeds the rate of heat loss and the auto-ignition temperature is reached. Classification 2.2.42.1.4. Substances and articles classified in Class 4.2 are listed in table A of Chapter 3.2. The assignment of substances and articles not mentioned by name in table A of Chapter 3.2 to the relevant specific N.O.S. entry of 2.2.42.3 in accordance with the requirements of Chapter 2.1 can be based on experience or the results of the test procedures in accordance with the Manual of Tests and Criteria, Part III, Section 33.3. Assignment to general N.O.S. entries of Class 4.2 shall be based on the results of the test procedures inaccordance with the Manual of Tests and Criteria, Part III, section 33.3; experience shall also be taken into account when it leads to a more stringent assignment. 2.2.42.1.5. When substances or articles not mentioned by name are assigned to one of the entries listed in 2.2.42.3 on the basis of the test procedures in accordance with the Manual of Tests and Criteria, Part III, section 33.3, the following criteria shall apply: (a) Solids liable to spontaneous combustion (pyrophoric) shall be assigned to Class 4.2 when they ignite on falling from a height of 1 m or within five minutes; (b) Liquids liable to spontaneous combustion (pyrophoric) shall be assigned to Class 4.2 when: (i) on being poured on an inert carrier, they ignite within five minutes, or (ii) in the event of a negative result of the test according to (i), when poured on a dry, indented filter paper (Whatman No. 3 filter), they ignite or carbonize it within five minutes; (c) Substances in which, in a 10 cm sample cube, at 140 °C test temperature, spontaneous combustion or a rise in temperature to over 200 °C is observed within 24 hours shall be assigned to Class 4.2. This criterion is based on the temperature of the spontaneous combustion of charcoal, which is at 50 °C for a sample cube of 27 m3. Substances with a temperature of spontaneous combustion higher than 50 °C for a volume of 27 m3 are not to be assigned to Class 4.2. NOTES: 1. Substances carried in packages with a volume of not more than 3 m3 are exempted from Class 4.2 if, tested with a 10 cm sample cube at 120 °C, no spontaneous combustion nor a rise in temperature to over 180 °C is observed within 24 hours. 2. Substances carried in packages with a volume of not more than 450 litres are exempted from Class 4.2 if, tested with a 10 cm sample cube at 100 °C, no spontaneous combustion nor a rise in temperature to over 160 °C is observed within 24 hours. 2.2.42.1.6.

Class 5.2 Organic peroxides 2.2.52.1. Criteria 2.2.52.1.1. The heading of Class 5.2 covers organic peroxides and formulations of organic peroxides. 2.2.52.1.2. The substances of Class 5.2 are subdivided as follows: - P1 Organic peroxides, not temperature controlled; - P2 Organic peroxides, temperature-controlled (not to be accepted for carriage). Definition 2.2.52.1.3. Organic peroxides are organic substances which contain the bivalent -O-O- structure and may be considered derivatives of hydrogen peroxide, where one or both of the hydrogen atoms have been replaced by organic radicals. Properties 2.2.52.1.4. Organic peroxides are liable to exothermic decomposition at normal or elevated temperatures. The decomposition can be initiated by heat, contact with impurities (e.g. acids, heavy-metal compounds, amines), friction or impact. The rate of decomposition increases with temperature and varies with the organic peroxide formulation. Decomposition may result in the evolution of harmful, or flammable, gases or vapours. For certain organic peroxides the temperature shall be controlled during transport. Some organic peroxides may decompose explosively, particularly if confined. This characteristic may be modified by the addition of diluents or by the use of appropriate packagings. Many organic peroxides burn vigorously. Contact of organic peroxides with the eyes is to be avoided. Some organic peroxides will cause serious injury to the cornea, even after brief contact, or will be corrosive to the skin. NOTE: Test methods for determining the flammability of organic peroxides are set out in the Manual of Tests and Criteria, Part III, sub-section 32.4. Because organic peroxides may react vigorously when heated, it is recommended to determine their flash-point using small sample sizes such as described in ISO 3679:1983. Classification 2.2.52.1.5. Any organic peroxide shall be considered for classification in Class 5.2 unless the organic peroxide formulation contains: (a) Not more than 1,0 % available oxygen from the organic peroxides when containing not more than 1,0 % hydrogen peroxide; (b) Not more than 0,5 % available oxygen from the organic peroxides when containing more than 1,0 % but not more than 7,0 % hydrogen peroxide. NOTE: The available oxygen content (%) of an organic peroxide formulation is given by the formula >PIC FILE= "L_2004121EN.008601.TIF"> where: ni= number of peroxygen groups per molecule of organic peroxide i; ci= concentration (mass %) of organic peroxide i; and mi= molecular mass of organic peroxide i. 2.2.52.1.6. Organic peroxides are classified into seven types according to the degree of danger they present. The types of organic peroxide range from type A, which is not accepted for carriage in the packaging in which it is tested, to type G, which is not subject to the requirements of Class 5.2. The classification of types B to F is directly related to the maximum quantity allowed in one packaging. The principles to be applied to the classification of substances not listed in 2.2.52.4 are set out in the Manual of Tests and Criteria, Part II. 2.2.52.1.7. Organic peroxides and formulations of organic peroxides which have already been classified and assigned to the appropriate generic entry are listed in 2.2.52.4 together with the applicable UN number and packing method. These generic entries specify: - the type (B to F) of organic peroxide (see 2.2.52.1.6 above); - physical state (liquid/solid). Mixtures of these formulations may be classified as the same type of organic peroxide as that of the most dangerous component and be carried under the conditions of transport given for this type. However, as two stable components can form a thermally less stable mixture, the self-accelerating decomposition temperature (SADT) of the mixture shall be determined. 2.2.52.1.8. Classification of organic peroxides, formulations or mixtures of organic peroxides not listed in 2.2.52.4 and assignment to a collective entry shall be made by the competent authority of the country of origin. The statement of approval shall contain the classification and the relevant transport conditions. If the country of origin is not a COTIF Member State, the classification and conditions of carriage shall be recognized by the competent authority of the first COTIF Member State reached by the consignment. 2.2.52.1.9. Samples of organic peroxides or formulations of organic peroxides not listed in 2.2.52.4, for which a complete set of test results is not available and which are to be carried for further testing or evaluation, shall be assigned to one of the appropriate entries for organic peroxides type C provided the following conditions are met: - the available data indicate that the sample would be no more dangerous than organic peroxides type B; - the sample is packaged in accordance with packing method OP2 and the quantity per wagon is limited to 10 kg; - samples requiring temperature control shall not be accepted for carriage by rail. Desensitization of organic peroxides 2.2.52.1.10. In order to ensure safety during carriage, organic peroxides are in many cases desensitized by organic liquids or solids, inorganic solids or water. Where a percentage of a substance is stipulated, this refers to the percentage by mass, rounded to the nearest whole number. In general, desensitization shall be such that, in case of spillage, the organic peroxide will not concentrate to a dangerous extent. 2.2.52.1.11. Unless otherwise stated for the individual organic peroxide formulation, the following definition(s) shall apply to diluents used for desensitization: - diluents type A are organic liquids which are compatible with the organic peroxide and which have a boiling point of not less than 150 °C. Type A diluents may be used for desensitizing all organic peroxides. - diluents type B are organic liquids which are compatible with the organic peroxide and which have a boiling point of less than 150 °C but not less than 60 °C and a flash-point of not less than 5 °C. Type B diluents may be used for desensitization of all organic peroxides provided that the boiling point of the liquid is at least 60 °C higher than the SADT in a 50 kg package. 2.2.52.1.12. Diluents, other than type A or type B, may be added to organic peroxide formulations as listed in 2.2.52.4 provided that they are compatible. However, replacement of all or part of a type A or type B diluent by another diluent with differing properties requires that the organic peroxide formulation be re-assessed in accordance with the normal acceptance procedure for Class 5.2. 2.2.52.1.13. Water may only be used for the desensitization of organic peroxides which are listed in 2.2.52.4 or in the competent authority decision according to 2.2.52.1.8 as being "with water" or "as a stable dispersion in water". Samples of organic peroxides or formulations of organic peroxides not listed in 2.2.52.4 may also be desensitized with water provided the requirements of 2.2.52.1.9 are met. 2.2.52.1.14. Organic and inorganic solids may be used for desensitization of organic peroxides provided that they are compatible. Compatible liquids and solids are those which have no detrimental influence on the thermal stability and hazard type of the organic peroxide formulation. 2.2.52.1.15. - 2.2.52.1.18. (Reserved) 2.2.52.2. Substances not accepted for carriage The following organic peroxides shall not be accepted for carriage under the requirements of Class 5.2: - Organic peroxides, type A (see Manual of Tests and Criteria, Part II, paragraph 20.4.3 (a)); - The following organic peroxides requiring temperature control are not to be accepted for carriage by rail: - organic peroxides, types B and C with an (SADT) <= 50 °C: UN 3111 ORGANIC PEROXIDE TYPE B, LIQUID, TEMPERATURE CONTROLLED; UN 3112 ORGANIC PEROXIDE TYPE B, SOLID, TEMPERATURE CONTROLLED; UN 3113 ORGANIC PEROXIDE TYPE C, LIQUID, TEMPERATURE CONTROLLED; UN 3114 ORGANIC PEROXIDE TYPE C, SOLID, TEMPERATURE CONTROLLED; - organic peroxides type D showing a violent or medium effect when heated under confinement with an SADT <= 50 °C or showing a low or no effect when heated under confinement with an SADT <= 45 °C: UN 3115 ORGANIC PEROXIDE TYPE D, LIQUID, TEMPERATURE CONTROLLED; UN 3116 ORGANIC PEROXIDE TYPE D, SOLID, TEMPERATURE CONTROLLED; - organic peroxides types E and F with an SADT<= 45 °C: UN 3117 ORGANIC PEROXIDE TYPE E, LIQUID, TEMPERATURE CONTROLLED; UN 3118 ORGANIC PEROXIDE TYPE E, SOLID, TEMPERATURE CONTROLLED; UN 3119 ORGANIC PEROXIDE TYPE F, LIQUID, TEMPERATURE CONTROLLED; UN 3120 ORGANIC PEROXIDE TYPE F, SOLID, TEMPERATURE CONTROLLED; 2.2.52.3.

Class 6.1 Toxic substances 2.2.61.1. Criteria 2.2.61.1.1. The heading of Class 6.1 covers substances of which it is known by experience or regarding which it is presumed from experiments on animals that in relatively small quantities they are able by a single action or by action of short duration to cause damage to human health, or death, by inhalation, by cutaneous absorption or by ingestion. 2.2.61.1.2. Substances of Class 6.1 are subdivided as follows: >TABLE> Definitions 2.2.61.1.3. For the purposes of this Directive: LD50 for acute oral toxicity is that dose of the substance administered which is most likely to cause death within 14 days in one half of both male and female young adult albino rats. The number of animals tested shall be sufficient to give a statistically significant result and be in conformity with good pharmacological practice. The result is expressed in milligrams per kg body mass. LD50 for acute dermal toxicity is that dose of the substance which, administered by continuous contact for 24 hours with the bare skin of albino rabbits, is most likely to cause death within 14 days in one half of the animals tested. The number of animals tested shall be sufficient to give a statistically significant result and be in conformity with good pharmacological practice. The result is expressed in milligrams per kg body mass. LC50 for acute toxicity on inhalation is that concentration of vapour, mist or dust which, administered by continuous inhalation to both male and female young adult albino rats for one hour, is most likely to cause death within 14 days in one half of the animals tested. A solid substance shall be tested if at least 10 % (by mass) of its total mass is likely to be dust in a respirable range, e.g. the aerodynamic diameter of that particle-fraction is 10 μm or less. A liquid substance shall be tested if a mist is likely to be generated in a leakage of the transport containment. Both for solid and liquid substances more than 90 % (by mass) of a specimen prepared for inhalation toxicity shall be in the respirable range as defined above. The result is expressed in milligrams per litre of air for dusts and mists or in millilitres per cubic metre of air (parts per million) for vapours. Classification and assignment of packing groups 2.2.61.1.4. Substances of Class 6.1 shall be classified in three packing groups according to the degree of danger they present for carriage, as follows: Packing group I: highly toxic substances Packing group II: toxic substances Packing group III: slightly toxic substances. 2.2.61.1.5. Substances, mixtures, solutions and articles classified in Class 6.1 are listed in table A of Chapter 3.2. The assignment of substances, mixtures and solutions not mentioned by name in table A of Chapter 3.2 to the relevant entry of 2.2.61.3 and to the relevant packing group in accordance with the requirements of Chapter 2.1, shall be made according to the following criteria in 2.2.61.1.6 to 2.2.61.1.11. 2.2.61.1.6. To assess the degree of toxicity, account shall be taken of human experience of instances of accidental poisoning, as well as special properties possessed by any individual substances: liquid state, high volatility, any special likelihood of cutaneous absorption, and special biological effects. 2.2.61.1.7. In the absence of observations on humans, the degree of toxicity shall be assessed using the available data from animal experiments in accordance with the table below: >TABLE> 2.2.61.1.7.1. Where a substance exhibits different degrees of toxicity for two or more kinds of exposure, it shall be classified under the highest such degree of toxicity. 2.2.61.1.7.2. Substances meeting the criteria of Class 8 and with an inhalation toxicity of dusts and mists (LC50) leading to packing group I shall only be accepted for an allocation to Class 6.1 if the toxicity through oral ingestion or dermal contact is at least in the range of packing groups I or II. Otherwise an assignment to Class 8 shall be made if appropriate(see footnote (6) in 2.2.8.1.4). 2.2.61.1.7.3. The criteria for inhalation toxicity of dusts and mists are based on LC50 data relating to 1-hour exposure, and where such information is available it shall be used. However, where only LC50 data relating to 4-hour exposure are available, such figures can be multiplied by four and the product substituted in the above criteria, i.e. LC50 value multiplied by four (4 hour) is considered the equivalent of LC50 (1 hour). Inhalation toxicity of vapours 2.2.61.1.8. Liquids giving off toxic vapours shall be classified into the following groups where "V" is the saturated vapour concentration (volatility) (in ml/m3 of air) at 20 °C and standard atmospheric pressure: >TABLE> These criteria for inhalation toxicity of vapours are based on LC50 data relating to 1-hour exposure, and where such information is available, it shall be used. However, where only LC50 data relating to 4-hour exposure to the vapours are available, such figures can be multiplied by two and the product substituted in the above criteria, i.e. LC50 (4 hour) × 2 is considered the equivalent of LC50 (1 hour). Group borderlines inhalation toxicity of vapours >PIC FILE= "L_2004121EN.010301.TIF"> In this figure, the criteria are expressed in graphical form, as an aid to easy classification. However, due to approximations inherent in the use of graphs, substances falling on or near group borderlines shall be checked using numerical criteria. Mixtures of liquids 2.2.61.1.9. Mixtures of liquids which are toxic on inhalation shall be assigned to packing groups according to the following criteria: 2.2.61.1.9.1. If LC50 is known for each of the toxic substances constituting the mixture, the packing group may be determined as follows: (a) calculation of the LC50 of the mixture: >PIC FILE= "L_2004121EN.010401.TIF"> where fi= molar fraction of constituent i of the mixture. LC50i= average lethal concentration of constituent i in ml/m3. (b) calculation of volatility of each mixture constituent: >PIC FILE= "L_2004121EN.010402.TIF"> where Pi= partial pressure of constituent i in kPa at 20 °C and at standard atmospheric pressure. (c) calculation of the ratio of volatility to LC50: >PIC FILE= "L_2004121EN.010403.TIF"> (d) the values calculated for LC50 (mixture) and R are then used to determine the packing group of the mixture: Packing group I R >= 10 and LC50 (mixture) <= 1000 ml/m3; Packing group II R >= 1 and LC50 (mixture) <= 3000 ml/m3, if the mixture does not meet the criteria for packing group I Packing group III R >= 1/5 and LC50 (mixture) <= 5000 ml/m3, if the mixture does not meet the criteria of packing groups I or II. 2.2.61.1.9.2. In the absence of LC50 data on the toxic constituent substances, the mixture may be assigned to a group based on the following simplified threshold toxicity tests. When these threshold tests are used, the most restrictive group shall be determined and used for carrying the mixture. 2.2.61.1.9.3. A mixture is assigned to packing group I only if it meets both of the following criteria: (a) A sample of the liquid mixture is vaporized and diluted with air to create a test atmosphere of 1000 ml/m3 vaporized mixture in air. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have an LC50 equal to or less than 1000 ml/m3; (b) A sample of vapour in equilibrium with the liquid mixture is diluted with 9 equal volumes of air to form a test atmosphere. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have a volatility equal to or greater than 10 times the mixture LC50. 2.2.61.1.9.4. A mixture is assigned to packing group II only if it meets both of the following criteria, and does not meet the criteria for packing group I: (a) A sample of the liquid mixture is vaporized and diluted with air to create a test atmosphere of 3000 ml/m3 vaporized mixture in air. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have an LC50 equal to or less than 3000 ml/m3; (b) A sample of the vapour in equilibrium with the liquid mixture is used to form a test atmosphere. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have a volatility equal to or greater than the mixture LC50. 2.2.61.1.9.5. A mixture is assigned to packing group III only if it meets both of the following criteria, and does not meet the criteria for packing groups I or II: (a) A sample of the liquid mixture is vaporized and diluted with air to create a test atmosphere of 5000 ml/m3 vaporized mixture in air. Ten albino rats (5 male and 5 female) are exposed to the test atmosphere for 1 hour and observed for 14 days. If five or more of the animals die within the 14-day observation period, the mixture is presumed to have an LC50 equal to or less than 5000 ml/m3; (b) The vapour concentration (volatility) of the liquid mixture is measured and if the vapour concentration is equal to or greater than 1000 ml/m3, the mixture is presumed to have a volatility equal to or greater than 1/5 the mixture LC50. Methods for determining oral and dermal toxicity of mixtures 2.2.61.1.10. When classifying and assigning the appropriate packing group to mixtures in Class 6.1 in accordance with the oral and dermal toxicity criteria (see 2.2.61.1.3), it is necessary to determine the acute LD50 of the mixture. 2.2.61.1.10.1. If a mixture contains only one active substance, and the LD50 of that constituent is known, in the absence of reliable acute oral and dermal toxicity data on the actual mixture to be carried, the oral or dermal LD50 may be obtained by the following method: >PIC FILE= "L_2004121EN.010501.TIF"> 2.2.61.1.10.2. If a mixture contains more than one active constituent, there are three possible approaches that may be used to determine the oral or dermal LD50 of the mixture. The preferred method is to obtain reliable acute oral and dermal toxicity data on the actual mixture to be carried. If reliable, accurate data is not available, then either of the following methods may be performed: (a) Classify the formulation according to the most hazardous constituent of the mixture as if that constituent were present in the same concentration as the total concentration of all active constituents; or (b) Apply the formula: >PIC FILE= "L_2004121EN.010502.TIF"> where: C= the percentage concentration of constituent A, B, ... Z in the mixture T= the oral LD50 values of constituent A, B, ... Z TM= the oral LD50 value of the mixture. NOTE: This formula can also be used for dermal toxicities provided that this information is available for all constituents. The use of this formula does not take into account any potentiation or protective phenomena. Classification of pesticides 2.2.61.1.11. All active pesticide substances and their preparations for which the LC50 and/or LD50 values are known and which are classified in Class 6.1 shall be classified under appropriate packing groups in accordance with the criteria given in 2.2.61.1.6 to 2.2.61.1.9. Substances and preparations which are characterized by subsidiary risks shall be classified according to the precedence of hazard table in 2.1.3.9 with the assignment of appropriate packing groups. 2.2.61.1.11.1. If the oral or dermal LD50 value for a pesticide preparation is not known, but the LD50 value of its active substance(s) is known, the LD50 value for the preparation may be obtained by applying the procedures in 2.2.61.1.10. NOTE: LD50 toxicity data for a number of common pesticides may be obtained from the most current edition of the document "The WHO Recommended Classification of Pesticides by Hazard and Guidelines to Classification" available from the International Programme on Chemical Safety, World Health Organisation (WHO), 1211 Geneva 27, Switzerland. While that document may be used as a source of LD50 data for pesticides, its classification system shall not be used for purposes of transport classification of, or assignment of packing groups to, pesticides, which shall be in accordance with the requirements of this Directive. 2.2.61.1.11.2. The proper shipping name used in the transport of the pesticide shall be selected on the basis of the active ingredient, of the physical state of the pesticide and any subsidiary risks it may exhibit (see 3.1.2). 2.2.61.1.12. If substances of Class 6.1, as a result of admixtures, come into categories of risk different from those to which the substances mentioned by name in table A of Chapter 3.2 belong, these mixtures or solutions shall be listed under the entries to which they belong on the basis of their actual degree of danger. NOTE: For the classification of solutions and mixtures (such as preparations and wastes), see also 2.1.3. 2.2.61.1.13. On the basis of the criteria of 2.2.61.1.4 to 2.2.61.1.10, it may also be determined whether the nature of a solution or mixture mentioned by name or containing a substance mentioned by name is such that the solution or mixture is not subject to the requirements for this Class. 2.2.61.1.14. Substances, solutions and mixtures, with the exception of substances and preparations used as pesticides, which do not meet the criteria of Directives 67/548/EEC(11) or 88/379/EEG(12) as amended and which are not therefore classified as highly toxic, toxic or harmful according to these directives, as amended, may be considered as substances not belonging to Class 6.1. 2.2.61.2. Substances not accepted for carriage 2.2.61.2.1. Chemically unstable substances of Class 6.1 shall not be accepted for carriage unless the necessary steps have been taken to prevent their dangerous decomposition or polymerization during carriage. To this end, it shall in particular be ensured that receptacles and tanks do not contain any substance(s) likely to cause such a reaction. 2.2.61.2.2. The following substances and mixtures shall not be accepted for carriage: - Hydrogen cyanides (stabilized or in solutions), other than UN Nos 1051, 1613, 1614 and 3294; - metal carbonyls, having a flash-point below 23 °C, other than UN Nos 1259 NICKEL CARBONYL and 1994 IRON PENTACARBONYL; - 2,3,7,8-TETRACHLORODIBENZO-P-DIOXINE (TCDD) in concentrations considered highly toxic in accordance with the criteria in 2.2.61.1.7; - 2249 DICHLORODIMETHYL ETHER, SYMMETRICAL; - preparations of phosphides without additives inhibiting the emission of flammable gases. The following substances shall not be accepted for carriage by rail: - barium azide, dry or with less than 50 % water or alcohols - UN 0135 MERCURY FULMINATE, WETTED 2.2.61.3.

Criteria 2.2.62.1.1. The heading of Class 6.2 covers infectious substances. Infectious substances are those substances known or reasonably expected to contain pathogens. Pathogens are defined as micro-organisms (including bacteria, viruses, rickettsia, parasites, fungi) or recombinant micro-organisms (hybrid or mutant), that are known or reasonably expected to cause infectious disease in animals or humans. For the purposes of this Class, viruses, micro-organisms as well as articles contaminated with these shall be considered as substances of this Class. NOTES: 1. However, they are not subject to the requirements applicable to this Class if they are unlikely to cause human or animal disease. 2. Infectious substances are subject to the requirements applicable to this Class only if they are capable of spreading disease to humans or animals when exposure to them occurs. 3. Genetically modified micro-organisms and organisms, biological products, diagnostic specimens and infected live animals shall be assigned to this Class if they meet the conditions for this Class. 4. Toxins from plant, animal or bacterial sources which do not contain any infectious substances or organisms or which are not contained in them are substances of Class 6.1, UN No 3172. 2.2.62.1.2. Substances of Class 6.2 are subdivided as follows: >TABLE> Definitions and classification 2.2.62.1.3. Infectious substances shall be classified in Class 6.2 and assigned to UN Nos 2814 or 2900, as appropriate, on the basis of their allocation to one of three risk groups based on criteria developed by the World Health Organization (WHO) and published in the WHO "Laboratory Biosafety Manual, second edition (1993)". A risk group is characterized by the pathogenicity of the organism, the mode and relative ease of transmission, the degree of risk to both an individual and a community, and the reversibility of the disease through the availability of known and effective preventive agents and treatment. The criteria for each risk group according to the level of risk are as follows: (a) Risk group 4: a pathogen that usually causes serious human or animal disease and that can be readily transmitted from one individual to another, directly or indirectly, and for which effective treatment and preventive measures are not usually available (i.e., high individual and community risk). (b) Risk group 3: a pathogen that usually causes serious human or animal disease but does not ordinarily spread from one infected individual to another, and for which effective treatment and preventive measures are available (i.e. high individual risk and low community risk). (c) Risk group 2: a pathogen that can cause human or animal disease but is unlikely to be a serious hazard, and, while capable of causing serious infection on exposure, for which effective treatment and preventive measures are available and the risk of spread of infection is limited (i.e. moderate individual risk and low community risk). NOTE: Risk group 1 includes micro-organisms that are unlikely to cause human or animal disease (i.e. no, or very low, individual or community risk). Substances containing only such micro-organisms are not considered infectious substances for the purposes of these requirements. 2.2.62.1.4. Infectious substances affecting animals only (group I2 in 2.2.62.1.2) and of risk group 2 are assigned to packing group II. 2.2.62.1.5. Biological products are those products derived from living organisms, that are manufactured and distributed in accordance with the requirements of national governmental authorities which may have special licensing requirements, and are used either for prevention, treatment, or diagnosis of disease in humans or animals, or for development, experimental or investigational purposes related thereto. They include, but are not limited to, finished or unfinished products such as vaccines and diagnostic products. For the purposes of this Directive, biological products are divided into the following groups: (a) Those which contain pathogens in risk group 1; those which contain pathogens under such conditions that their ability to produce disease is very low to none; and those known not to contain pathogens. Substances in this group are not considered infectious substances for the purposes of this Directive; (b) Those manufactured and packaged in accordance with the requirements of national governmental health authorities and transported for the purposes of final packaging or distribution, and use for personal health care by medical professionals or individuals. Substances in this group are not subject to the requirements applicable to Class 6.2; (c) Those known or reasonably expected to contain pathogens in risk groups 2, 3, or 4 and which do not meet the criteria of (b) above. Substances in this group shall be classified in Class 6.2 under UN Nos 2814 or 2900, as appropriate. NOTE: Some licensed biological products may present a biohazard in certain parts of the world only. In that case competent authorities may require these biological products to comply with the requirements for infectious substances or may impose other restrictions. 2.2.62.1.6. Diagnostic specimens are any human or animal material including, but not limited to, excreta, secreta, blood and its components, tissue and tissue fluids being transported for purposes of diagnosis or research, but excluding live infected animals. For the purposes of RID, diagnostic specimens are divided into the following groups: (a) Those known or reasonably expected to contain pathogens in risk groups 2, 3 or 4 and those where a relatively low probability exists that pathogens of risk group 4 are present. Such substances shall be classified in Class 6.2 under UN Nos 2814 or 2900, as appropriate. Specimens carried for the purposes of initial or confirmatory testing for the presence of pathogens fall within this group; (b) Those where a relatively low probability exists that pathogens of risk groups 2 or 3 are present. Such substances shall be classified in 6.2 under UN No 2814 or 2900, as appropriate. Specimens carried for the purpose of initial diagnosis for other than the presence of pathogens or specimens arried for routine screening fall within this group; (c) Those known not to contain pathogens. Such substances are not considered as substances of Class 6.2. 2.2.62.1.7. Genetically modified micro-organisms and organisms(13) are micro-organisms and organisms in which the genetic material has been deliberately altered by technical methods or by means that cannot occur naturally in nature. For the purposes of RID, genetically modified micro-organisms and organisms are divided into the following groups: (a) Genetically modified micro-organisms which meet the definition of an infectious substance given in 2.2.62.1.1 shall be classified in Class 6.2 and assigned to UN Nos 2814 or 2900; (b) Genetically modified organisms, which are known or suspected to be dangerous to humans, animals or the environment, shall be carried in accordance with conditions specified by the competent authority of the country of origin; (c) Animals which contain or are contaminated with genetically modified micro-organisms and organisms that meet the definition of an infectious substance shall be carried in accordance with conditions specified by the competent authority of the country of origin; (d) Except when authorized for unconditional use by the Governments of the countries of origin, transit and destination, genetically modified micro-organisms which do not meet the definition of infectious substances but which are capable of altering animals, plants or microbiological substances in a way not normally the result of natural reproduction shall be classified in Class 9 and assigned to UN No 3245. NOTE: Genetically modified micro-organisms which are infectious within the meaning of this Class may not be assigned to UN No 3291. 2.2.62.1.8.

Where the chemical form of each radionuclide is known, it is permissible to use the A2 value related to its solubility class as recommended by the International Commission on Radiological Protection, if the chemical forms under both normal and accident conditions of transport are taken into consideration. Alternatively, the radionuclide values in Table 2.2.7.7.2.2 may be used without obtaining competent authority approval.

In the calculations of A1 and A2 for a radionuclide not in Table 2.2.7.7.2.1, a single radioactive decay chain in which the radionuclides are present in their naturally occurring proportions, and in which no daughter nuclide has a half-life either longer than 10 days or longer than that of the parent nuclide, shall be considered as a single radionuclide; and the activity to be taken into account and the A1 or A2 value to be applied shall be those corresponding to the parent nuclide of that chain. In the case of radioactive decay chains in which any daughter nuclide has a half-life either longer than 10 days or greater than that of the parent nuclide, the parent and such daughter nuclides shall be considered as mixtures of different nuclides. 2.2.7.7.2.4. For mixtures of radionuclides, the determination of the basic radionuclide values referred to in 2.2.7.7.2.1 may be determined as follows: >PIC FILE= "L_2004121EN.013601.TIF"> where, f(i) is the fraction of activity or activity concentration of radionuclide i in the mixture; X(i) is the appropriate value of A1 or A2, or the activity concentration for exempt material or the activity limit for an exempt consignment as appropriate for the radionuclide i; and Xm is the derived value of A1 or A2, or the activity concentration for exempt material or the activity limit for an exempt consignment in the case of a mixture. 2.2.7.7.2.5. When the identity of each radionuclide is known but the individual activities of some of the radionuclides are not known, the radionuclides may be grouped and the lowest radionuclide value, as appropriate, for the radionuclides in each group may be used in applying the formulas in 2.2.7.7.2.4 and 2.2.7.7.1.4.2. Groups may be based on the total alpha activity and the total beta/gamma activity when these are known, using the lowest radionuclide values for the alpha emitters or beta/gamma emitters, respectively. 2.2.7.7.2.6.

General Unless otherwise provided for in Chapter 2.2 or in this section, the test methods to be used for the classification of dangerous goods are those described in the Manual of Tests and Criteria. 2.3.1. Exudation test for blasting explosives of type A 2.3.1.1. Blasting explosives of type A (UN 0081) shall, if they contain more than 40 % liquid nitric ester, in addition to the testing specified in the Manual of Tests and Criteria, satisfy the following exudation test. 2.3.1.2. The apparatus for testing blasting explosive for exudation (figs. 1 to 3) consists of a hollow bronze cylinder. This cylinder, which is closed at one end by a plate of the same metal, has an internal diameter of 15,7 mm and a depth of 40 mm. It is pierced by 20 holes 0,5 mm in diameter (four sets of five holes) on the circumference. A bronze piston, cylindrically fashioned over a length of 48 mm and having a total length of 52 mm, slides into the vertically placed cylinder. The piston, whose diameter is 15,6 mm, is loaded with a mass of 2220 g so that a pressure of 120 kPa (1,2 bar) is exerted on the base of the cylinder. 2.3.1.3. A small plug of blasting explosive weighing 5 to 8 g, 30 mm long and 15 mm in diameter, is wrapped in very fine gauze and placed in the cylinder; the piston and its loading mass are then placed on it so that the blasting explosive is subjected to a pressure of 120 kPa (1,2 bar). The time taken for the appearance of the first signs of oily droplets (nitroglycerin) at the outer orifices of the cylinder holes is noted. 2.3.1.4. The blasting explosive is considered satisfactory if the time elapsing before the appearance of the liquid exudations is more than five minutes, the test having been carried out at a temperature of 15 °C to 25 °C.

After this, it is left standing for half an hour, then the liberated iodine is titrated with a decinormal solution of sodium thiosulphate, no indicator being added; complete discoloration indicates the end of the reaction. If n is the number of cm3 of thiosulphate solution required, the percentage of peroxide (calculated as H2O2) present in the sample is obtained by the formula >PIC FILE= "L_2004121EN.015001.TIF"> 2.3.4. Test for determining fluidity To determine the fluidity of liquid, viscous or pasty substances and mixtures, the following test method shall be used. 2.3.4.1. Test apparatus Commercial penetrometer conforming to ISO Standard 2137-1985, with a guide rod of 47,5 g ± 0,05 g; sieve disc of duralumin with conical bores and a mass of 102,5 g ± 0,05 g (see Figure 1); penetration vessel with an inside diameter of 72 mm to 80 mm for reception of the sample. 2.3.4.2. Test procedure The sample is poured into the penetration vessel not less than half an hour before the measurement. The vessel is then hermetically closed and left standing until the measurement. The sample in the hermetically closed penetration vessel is heated to 35 °C ± 0,5 °C and is placed on the penetrometer table immediately prior to measurement (not more than two minutes). The point S of the sieve disc is then brought into contact with the surface of the liquid and the rate of penetration is measured. 2.3.4.3. Evaluation of test results A substance is pasty if, after the centre S has been brought into contact with the surface of the sample, the penetration indicated by the dial gauge: (a) after a loading time of 5 s ± 0,1 s, is less than 15,0 mm ± 0,3 mm; or (b) after a loading time of 5 s ± 0,1 s, is greater than 15,0 mm ± 0,3 mm, but the additional penetration after another 55 s ± 0,5 s is less than 5,0 mm ± 0,5 mm. NOTE: In the case of samples having a flow point, it is often impossible to produce a steady level surface in the penetration vessel and, hence, to establish satisfactory initial measuring conditions for the contact of the point S. Furthermore, with some samples, the impact of the sieve disc can cause an elastic deformation of the surface and, in the first few seconds, simulate a deeper penetration. In all these cases, it may be appropriate to make the evaluation in (b). Figur 1 - Penetrometer >PIC FILE= "L_2004121EN.015101.TIF"> 2.3.5. Test for determining the ecotoxicity, persistence and bioaccumulation of substances in the aquatic environment for assignment to Class 9 NOTE: The test methods used shall be those adopted by the Organization for Economic Cooperation and Development (OECD) and the European Commission (EC). If other methods are used, they shall be internationally recognized, be equivalent to the OECD/EC tests and be referenced in test reports. 2.3.5.1. Acute toxicity for fish The object is to determine the concentration which causes 50 % mortality in the test species; this is the (LC50) value, namely, the concentration of the substance in water which will cause the death of 50 % of a test group of fish during a continuous period of testing of at least 96 hours. Appropriate types of fish include: striped brill (Brachydanio rerio), fathead minnow (Pimephales promelas) and rainbow trout (Oncorhynchus mykiss). The fish are exposed to the test substance added to the water in varying concentrations (+1 control). Observations are recorded at least every 24 hours. At the end of the 96-hour activity and, if possible, at each observation, the concentration causing the death of 50 % of the fish is calculated. The no observed effect concentration (NOEC) at 96 hours is also determined. 2.3.5.2. Acute toxicity for daphnia The object is to determine the effective concentration of the substance in water which renders 50 % of the daphnia unable to swim (EC50). The appropriate test organisms are daphnia magna and daphnia pulex. The daphnia are exposed for 48 hours to the test substance added to the water in varying concentrations. The no observed effect concentration (NOEC) at 48 hours is also determined. 2.3.5.3. Algal growth inhibition The object is to determine the effect of a chemical on the growth of algae under standard conditions. The change in biomass and the rate of growth with algae under the same conditions, but without the presence of the test chemical, are compared over 72 hours. The results are expressed as the effective concentration which reduces the rate of algal growth by 50 %, IC50r, and also the formation of the biomass, IC50b. 2.3.5.4. Tests for ready biodegradability The object is to determine the degree of biodegradation under standard aerobic conditions. The test substance is added in low concentrations to a nutrient solution containing aerobic bacteria. The progress of degradation is followed for 28 days by determining the parameter specified in the test method used. Several equivalent test methods are available. The parameters include reduction of dissolved organic carbon (DOC), carbon dioxide (CO2), generation of oxygen (O2) depletion. A substance is considered to be readily biodegradable if within not more than 28 days the following criteria are satisfied-within 10 days from when degradation first reaches 10 %: Reduction of DOC: 70 % Generation of CO2: 60 % of theoretical CO2 production Depletion of O2: 60 % of theoretical O2 requirement. The test may be continued beyond 28 days if the above criteria are not satisfied, but the result will represent the inherent biodegradability of the test substance. For assignment purposes, the "ready" result is normally required. Where only COD and BOD5 data are available, a substance is considered to be readily biodegradable if: >PIC FILE= "L_2004121EN.015301.TIF"> BOD (Biochemical Oxygen Demand) is defined as the mass of dissolved oxygen required by a specific volume of solution of the substance for the process of biochemical oxidation under prescribed conditions. The result is expressed as grams of BOD per gram of test substance. The normal test period is five days (BOD5) using a national standard test procedure. COD (Chemical Oxygen Demand) is a measure of the oxidizability of a substance, expressed as the equivalent amount in oxygen of an oxidizing reagent consumed by the substance under fixed laboratory conditions. The results are expressed in grams of COD per gram of substance. A national standard procedure may be used. 2.3.5.5. Tests for bioaccumulation potential 2.3.5.5.1. The object is to determine the potential for bioaccumulation either by the ratio at equilibrium of the concentration (c) of a substance in a solvent to that in water or by the bioconcentration factor (BCF). 2.3.5.5.2. The ratio at equilibrium of the concentration (c) of a substance in a solvent to that in water is normally expressed as a log10. The solvent and water shall have negligible miscibility and the substance shall not ionize in water. The solvent normally used is n-octanol. In the case of n-octanol and water, the result is: >PIC FILE= "L_2004121EN.015302.TIF"> where Pow is the partition coefficient obtained by dividing the concentration of the substance in n-octanol (co) by the concentration of the substance in water (cw). If log Pow >= 3,0 then the substance has a potential to bioaccumulate. 2.3.5.5.3. The bioconcentration factor (BCF) is defined as the ratio of the concentration of the test substance in the test fish (cf) to the concentration in the test water (cw) at steady state: >PIC FILE= "L_2004121EN.015303.TIF"> The principle of the test involves exposing fish to a solution or dispersion at known concentrations of the test substance in water. Continuous flow, static or semi-static procedures may be used according to the test procedure selected, based on the properties of the test substances. Fish are exposed to the test substances over a given period of time, followed by a period of no further exposure. During the second period, measurements are made of the rate of increase in the water of the test substance (i.e. the rate of excretion or depuration). (Full details of the various test procedures and the calculation method for the BCF are given in the OECD Guidelines for Testing of Chemicals, methods 305A to 305E, 12 May 1981). 2.3.5.5.4. A substance may have a log Pow greater than 3 and a BCF less than 100 which would indicate little or no potential to bioaccumulate. In cases of doubt, the BCF value takes precedence over log Pow, as indicated in the flow chart of the Procedure in 2.3.5.7. 2.3.5.6. Criteria A substance may be regarded as a pollutant to the aquatic environment if it satisfies one of the following criteria: The lowest of the values of the 96-hour LC50 for fish, the 48-hour EC50 for daphnia or the 72-hour IC50 for algae: - is less than or equal to 1 mg/l; - is greater than 1 mg/l but less than or equal to 10 mg/l, and the substance is not biodegradable; - is greater than 1 mg/l but less than or equal to 10 mg/l, and the log Pow is greater than or equal to 3,0 (unless the experimentally determined BCF is less than or equal to 100). 2.3.5.7 Procedure to be followed >PIC FILE= "L_2004121EN.015401.TIF"> Part 3 DANGEROUS GOODS LIST, SPECIAL PROVISIONS AND EXEMPTIONS RELATED TO DANGEROUS GOODS PACKED IN LIMITED QUANTITIES CHAPTER 3.1 General 3.1.1. Introduction In addition to the requirements referred to or given in the tables of this Part, the general requirements of each Part, Chapter and/or Section are to be observed. These general requirements are not given in the tables. When a general requirement is contradictory to a special requirement, the special requirement prevails. 3.1.2. Proper shipping name 3.1.2.1. The proper shipping name is that portion of the entry most accurately describing the goods in table A in Chapter 3.2, which is shown in upper case characters (plus any numbers, Greek letters, "sec", "tert", and the letters m, n, o, p, which form an integral part of the name). An alternative proper shipping name may be shown in brackets following the main proper shipping name (e.g. ETHANOL (ETHYL ALCOHOL)). Portions of an entry appearing in lower case need not be considered as part of the proper shipping name. 3.1.2.2. When conjunctions such as "and" or "or" are in lower case or when segments of the name are punctuated by commas, the entire name of the entry need not necessarily be shown in the consignment note or package markings. This is the case particularly when a combination of several distinct entries are listed under a single UN Number. Examples illustrating the selection of the proper shipping name for such entries are: (a) UN 1057 LIGHTERS or LIGHTER REFILLS - The proper shipping name is the most appropriate of the following possible combinations: - LIGHTERS - LIGHTER REFILLS; (b) UN 3207 ORGANOMETALLIC COMPOUND or COMPOUND SOLUTION or COMPOUND DISPERSION, WATER-REACTIVE, FLAMMABLE, N.O.S. The proper shipping name is the most appropriate of the following possible combinations: - ORGANOMETALLIC COMPOUND, WATER-REACTIVE, FLAMMABLE, N.O.S. - ORGANOMETALLIC COMPOUND SOLUTION, WATER-REACTIVE, FLAMMABLE, N.O.S. - ORGANOMETALLIC COMPOUND DISPERSION, WATER-REACTIVE, FLAMMABLE, N.O.S. each supplemented with the technical name of the goods (see 3.1.2.6.1). 3.1.2.3. Proper shipping names may be used in the singular or plural as appropriate. In addition, when qualifying words are used as part of the proper shipping name, their sequence on the consignment note or package markings is optional. For instance, "Dimethylamine aqueous solution" may alternatively be shown as "aqueous solution of dimethylamine". Commercial or military names for goods of Class 1 which contain the proper shipping name supplemented by additional descriptive text may be used. 3.1.2.4. Unless it is already included in capital letters in the name indicated in table A in Chapter 3.2, the qualifying word "LIQUID" or "SOLID", as appropriate, shall be added as part of the proper shipping name when a substance specifically listed by name may, due to the differing physical states of the various isomers of the substance, be either a liquid or a solid (e.g. DINITROTOLUENES, LIQUID; DINITROTOLUENES, SOLID). 3.1.2.5. Unless it is already included in capital letters in the name indicated in table A in Chapter 3.2, the qualifying word "MOLTEN" shall be added as part of the proper shipping name when a substance, which is a solid in accordance with the definition in 1.2.1, is carried or handed over for carriage in the molten state (e.g. ALKYLPHENOL, SOLID, N.O.S., MOLTEN). 3.1.2.6. Names of generic or "not otherwise specified" (N.O.S.) entries 3.1.2.6.1. For the purposes of documentation and marking of packages, when an "N.O.S." or "generic" proper shipping name is used, the proper shipping name shall be supplemented with the technical name of the goods, unless a national law or international convention prohibits its disclosure if it is a controlled substance. The particular "N.O.S." or "generic" entries for which this supplementary information is considered necessary have been allocated Special Provision 274 in column (6) of table A in Chapter 3.2. 3.1.2.6.1.1. The technical name (see definition in 1.2.1) shall be shown immediately following the proper shipping name. Trade names shall not be used for this purpose. In the case of pesticides, only ISO common name(s), other name(s) in the WHO Recommended Classification of Pesticides by Hazard and Guidelines to Classification, or the name(s) of the active substance(s) may be used. It shall be a recognized chemical name or another name currently used in scientific and technical handbooks, journals and texts. 3.1.2.6.1.2. When a mixture of dangerous goods is described by one of the "N.O.S." or "generic" entries to which Special Provision 274 has been allocated in column (6) of table A in Chapter 3.2, not more than the two constituents which most predominantly contribute to the hazard or hazards of a mixture need to be shown, excluding controlled substances when their disclosure is prohibited by national law or international convention. If a package containing a mixture is labelled with any subsidiary risk label, one of the two technical names shown in parentheses shall be the name of the constituent which compels the use of the subsidiary risk label. NOTE: see 5.4.1.2.2 3.1.2.6.1.3. Examples illustrating the selection of the proper shipping name supplemented with the technical name of goods for such N.O.S. entries are: UN 2003 METAL ALKYL, N.O.S. (trimethylgallium) UN 2902 PESTICIDE, LIQUID, TOXIC, N.O.S. (drazoxolon). 3.1.2.7. Mixtures and solutions containing one dangerous substance When mixtures and solutions have to be regarded as the dangerous substance listed by name in accordance with the classification requirements of 2.1.3.3, the qualifying word "SOLUTION" or "MIXTURE", as appropriate, shall be added as part of the proper shipping name, e.g. "ACETONE SOLUTION". In addition, the concentration of the solution or mixture may also be indicated, e.g. "ACETONE 75 % SOLUTION". CHAPTER 3.2 List of dangerous goods in UN number order 3.2.1. Explanations concerning table A: List of dangerous goods in UN number order As a rule, each row of table A in this Chapter deals with the substance(s) or article(s) covered by a specific UN number. However, when substances or articles belonging to the same UN number have different chemical properties, physical properties and/or transport conditions, several consecutive rows may be used for that UN number. Each column of table A is dedicated to a specific subject as indicated in the explanatory notes below. The intersection of columns and rows contains information concerning the subject treated in that column, for the substance(s) or article(s) of that row: - the first four cells identify the substance(s) or article(s) belonging to that row (additional information in that respect may be given by the special requirements referred to in column (6)); - the following cells give the applicable special requirements, either in the form of complete information or in coded form. The codes cross-refer to detailed information that is to be found in the Part, Chapter, Section and/or Sub-section indicated in the explanatory notes below. An empty cell means either that there is no special requirement and that only the general requirements apply, or that the transport restriction indicated in the explanatory notes is in force. The applicable general requirements are not referred to in the corresponding columns. The explanatory notes below indicate for every column the Part(s), Chapter(s), Section(s) and/or Sub-section(s) where these are to be found. >TABLE> >TABLE> CHAPTER 3.3 Special Requirements Applicable to certain articles or substances 3.3.1. When Column 6 of table A of Chapter 3.2 indicates that a special requirement is relevant to a substance or article, the meaning and requirements of that special requirement are as set out below. >TABLE> CHAPTER 3.4 Exemptions for the carriage of dangerous goods packed in limited quantities 3.4.1. Packagings used in accordance with 3.4.3 to 3.4.6 below, need only to conform to the general requirements of 4.1.1.1, 4.1.1.2 and 4.1.1.4 to 4.1.1.8. 3.4.2. When the code LQ 0 is shown in column (7) of table A in Chapter 3.2 for a given substance or article, that substance or article is not exempted from any of the applicable requirements of this Directive when it is packed in limited quantities, unless otherwise specified. 3.4.3. Unless otherwise provided in this Chapter, when one of the codes LQ 1 or LQ 2 is shown in column (7) of table A in Chapter 3.2 for a given substance or article, the requirements of other Chapters of this Directive do not apply to the carriage of that substance or article, provided: (a) the requirements of 3.4.5(a) to (c) are observed; with respect to these requirements, articles are considered to be inner packagings; (b) inner packagings meet the conditions of 6.2.1.2 when LQ 1 is shown, and the conditions of 6.2.1.2, 6.2.4.1 and 6.2.4.2 when LQ 2 is shown. 3.4.4. Unless otherwise provided in this Chapter, when one of the codes LQ 3, LQ 20, LQ 21 or LQ 29 is shown in column (7) of Table A in Chapter 3.2 for a given substance, the requirements of other Chapters of this Directive do not apply to the carriage of that substance, provided: (a) the substance is carried in combination packagings, the following outer packagings being allowed: - steel or aluminium drums with removable head; - steel or aluminium jerricans with removable head; - plywood or fibreboard drums; - plastics drums or jerricans with removable head; - boxes of natural wood, plywood, reconstituted wood, fibreboard, plastics, steel or aluminium; (b) the maximum quantity per inner packaging and per package, prescribed for the relevant code in the second and third column of the table in 3.4.6, are not exceeded; (c) each package is clearly and durably marked with: (i) the UN number of the goods contained therein, as given in column (1) of Table A in Chapter 3.2, preceded by the letters "UN"; (ii) in the case of different goods with different UN numbers within a single package: - the UN numbers of the goods contained therein, preceded by the letters "UN", or - the letters "LQ"(20). These markings shall be displayed within a diamond-shaped area surrounded by a line that measures at least 100 mm × 100 mm. If the size of the package so requires, the dimensions may be reduced, provided the markings remain clearly visible. 3.4.5. Unless otherwise provided in this Chapter, when one of the codes LQ 4 to LQ 19 and LQ 22 to LQ 28 is shown in column (7) of Table A in Chapter 3.2 for a given substance, the requirements of other Chapters of this Directive do not apply to the carriage of that substance, provided: (a) the substance is carried: - in combination packagings, in accordance with the requirements of 3.4.4(a), or - in metal or plastics inner packagings which are not liable to break or be easily punctured, placed in shrink-wrapped or stretch-wrapped trays; (b) the maximum quantity per inner packaging and per package, prescribed for the relevant code in the table in 3.4.6 (in the second and third column in the case of combination packagings, and in the fourth and fifth column in the case of shrink-wrapped or stretch-wrapped trays), are not exceeded; (c) each package is clearly and durably marked as indicated in 3.4.4(c). 3.4.6. Table >TABLE> Part 4 PACKING AND TANK PROVISIONS CHAPTER 4.1 Use of packagings, including intermediate bulk containers (IBCs) and large packagings Introductory notes NOTE 1. Packing groups Dangerous substances of all classes other than those of classes 1, 2, 5.2, 6.2 and 7 and than the self-reactive substances of Class 4.1 have for packing purposes been assigned to one or more of three Packing Groups in accordance with the degree of danger they present, i.e.: Packing Group I: substances presenting high danger; Packing Group II substances presenting medium danger; and Packing Group III substances presenting low danger. The Packing Group to which a substance is assigned is indicated in Table A of Chapter 3.2. NOTE 2. Explosives, self-reactive substances and organic peroxides Unless otherwise required in this Directive, the packagings, including IBCs and large packagings, used for goods of Class l, self-reactive substances of Class 4.1 and organic peroxides of Class 5.2 shall comply with the requirements for the medium danger group (Packing Group II). 4.1.1. General Requirements for the packing of dangerous goods, other than goods of classes 2, 6.2 or 7, in packagings, including IBCs and large packagings NOTE. Some of these general requirements may apply to the packing of goods of Class 2, 6.2 and 7. Refer to 4.1.6 (Class 2), 4.1.8 (Class 6.2), 4.1.9 (Class 7) and to the applicable packing instruction in 4.1.4. 4.1.1.1. Dangerous goods shall be packed in good quality packagings, including IBCs and large packagings, which shall be strong enough to withstand the shocks and loadings normally encountered during carriage, including trans-shipment between means of transport and/or warehouses as well as any removal from a pallet or overpack for subsequent manual or mechanical handling. Packagings, including IBCs and large packagings, shall be constructed and closed so as to prevent any loss of contents when prepared for transport which might be caused under normal conditions of transport, by vibration, or by changes in temperature, humidity or pressure (resulting from altitude, for example). No dangerous residue shall adhere to the outside of packagings, IBCs and large packagings during carriage. These requirements apply, as appropriate, to new, reused, reconditioned or remanufactured packagings and to new and reused IBCs and large packagings. 4.1.1.2. Parts of packagings, including IBCs and large packagings, which are in direct contact with dangerous goods: (a) shall not be affected or significantly weakened by those dangerous goods; and (b) shall not cause a dangerous effect e.g. catalysing a reaction or reacting with the dangerous goods. Where necessary, they shall be provided with a suitable inner coating or treatment. 4.1.1.3. Unless otherwise required in this Directive, each packaging, including IBCs and large packagings, except inner packagings, shall conform to a design type successfully tested in accordance with the requirements of 6.1.5, 6.5.4 or 6.6.5, respectively. The packagings for which the test is not required are listed in 6.1.1.3. 4.1.1.4. When filling packagings, including IBCs and large packagings, with liquids, sufficient ullage (outage) shall be left to ensure that neither leakage nor permanent distortion of the packaging occurs as a result of an expansion of the liquid caused by temperatures likely to occur during transport. Unless specific requirements are prescribed, liquids shall not completely fill a packaging at a temperature of 55 °C. However, sufficient ullage shall be left in an IBC to ensure that at the mean bulk temperature of 50 °C it is not filled to more than 98 % of its water capacity. For a filling temperature of 15 °C, the degree of filling shall be determined as follows, unless otherwise provided, either: (a) >TABLE> or (b) degree of filling >PIC FILE= "L_2004121EN.053601.TIF"> of the capacity of the packaging. In this formula α represents the mean coefficient of cubic expansion of the liquid substance between 15 °C and 50 °C; that is to say, for a maximum rise in temperature of 35 °C, α is calculated according to the formula: >PIC FILE= "L_2004121EN.053602.TIF"> d15 and d50 being the relative densities(21) of the liquid at 15 °C and 50 °C and tF the mean temperature of the liquid at the time of filling. 4.1.1.5. Inner packagings shall be packed in an outer packaging in such a way that, under normal conditions of carriage, they cannot break, be punctured or leak their contents into the outer packaging. Inner packagings that are liable to break or be punctured easily, such as those made of glass, porcelain or stoneware or of certain plastics materials, etc., shall be secured in outer packagings with suitable cushioning material. Any leakage of the contents shall not substantially impair the protective properties of the cushioning material or of the outer packaging. 4.1.1.6. Dangerous goods shall not be packed together in the same outer packaging or in large packagings, with dangerous or other goods if they react dangerously with each other (see definition of "dangerous reaction" in 1.2.1). NOTE. For mixed packing special requirements, see 4.1.10. 4.1.1.7. The closures of packagings containing wetted or diluted substances shall be such that the percentage of liquid (water, solvent or phlegmatizer) does not fall below the prescribed limits during transport. 4.1.1.7.1. Where two or more closure systems are fitted in series on an IBC, that nearest to the substance being carried shall be closed first. 4.1.1.8. Liquids may only be filled into inner packagings which have an appropriate resistance to internal pressure that may be developed under normal conditions of carriage. Where overpressure may develop in a package by the emission of gas from the contents (as a result of temperature increase or other cause), the packaging may be fitted with a vent, provided that the gas emitted will not cause danger on account of its toxicity, its flammability or the quantity released. A venting device shall be fitted if dangerous overpressure may develop due to normal decomposition of substances. The vent shall be so designed that, when the packaging is in the attitude in which it is intended to be carried, leakages of liquid and the penetration of foreign matter are prevented under normal conditions of carriage. 4.1.1.9. New, remanufactured or reused packagings, including IBCs and large packagings, or reconditioned packagings and repaired IBCs shall be capable of passing the tests prescribed in 6.1.5, 6.5.4 or 6.6.5 respectively. Before being filled and handed over for carriage, every packaging, including IBCs and large packagings, shall be inspected to ensure that it is free from corrosion, contamination or other damage and every IBC shall be inspected with regard to the proper functioning of any service equipment. Any packaging which shows signs of reduced strength as compared with the approved design type shall no longer be used or shall be so reconditioned, that it is able to withstand the design type tests. Any IBC which shows signs of reduced strength as compared with the tested design type shall no longer be used or shall be so repaired that it is able to withstand the design type tests. 4.1.1.10. Liquids shall be filled only into packagings, including IBCs, which have an appropriate resistance to the internal pressure that may develop under normal conditions of carriage. Packagings and IBCs marked with the hydraulic test pressure prescribed in 6.1.3.1(d) and 6.5.2.2.1 respectively shall be filled only with a liquid having a vapour pressure: (a) such that the total gauge pressure in the packaging or IBC (i.e. the vapour pressure of the filling substance plus the partial pressure of air or other inert gases, less 100 kPa) at 55 °C, determined on the basis of a maximum degree of filling in accordance with 4.1.1.4 and a filling temperature of 15 °C, will not exceed two-thirds of the marked test pressure; or (b) at 50 °C less than four-sevenths of the sum of the marked test pressure plus 100 kPa; or (c) at 55 °C less than two-thirds of the sum of the marked test pressure plus 100 kPa. Metal IBCs intended for the carriage of liquids shall not be used to carry liquids having a vapour pressure of more than 110kPa (1,1 bar) at 50 °C or 130kPa (1,3 bar) at 55 °C. Examples of required marked test pressures for packagings, including IBCs, calculated as in 4.1.1.10 (c) >TABLE> NOTE 1. For pure liquids the vapour pressure at 55 °C (Vp55) can often be obtained from scientific tables. NOTE 2. The table refers to the use of 4.1.1.10(c) only, which means that the marked test pressure shall exceed 1.5 times the vapour pressure at 55 °C less 100 kPa. When, for example, the test pressure for n-decane is determined according to 6.1.5.5.4 (a), the minimum marked test pressure may be lower. NOTE 3. For diethyl ether the required minimum test pressure under 6.1.5.5.5 is 250 kPa. 4.1.1.11. Empty packagings, including empty IBCs and empty large packagings, that have contained a dangerous substance are subject to the same requirements as those for a filled packaging, unless adequate measures have been taken to nullify any hazard. 4.1.1.12. Every packaging, including an IBC, intended to contain liquids shall successfully undergo a suitable leakproofness test, and be capable of meeting the appropriate test level indicated in 6.1.5.4.3 or 6.5.4.7 for the various types of IBCs: (a) before it is first used for carriage; (b) after remanufacturing or reconditioning of any packaging, before it is re-used for carriage; (c) after the repair of any IBC, before it is re-used for carriage. For this test the packaging, or IBC, need not have its closures fitted. The inner receptacle of a composite packaging or IBC may be tested witwood the outer packaging, provided the test results are not affected. This test is not necessary for - inner packagings of combination packagings or large packagings, - inner receptacles of composite packagings (glass, porcelain or stoneware), bearing the symbol "RID/ADR" in accordance with 6.1.3.1(a)(ii), - light gauge metal packagings bearing the symbol "RID/ADR" in accordance with 6.1.3.1(a)(ii) 4.1.1.13. Packagings, including IBCs, used for solids which may become liquid at temperatures likely to be encountered during carriage shall also be capable of containing the substance in the liquid state. 4.1.1.14. Packagings, including IBCs, used for powdery or granular substances shall be sift-proof or shall be provided with a liner. 4.1.1.15. For plastics drums and jerricans, rigid plastics IBCs and composite IBCs with plastics inner receptacles, unless otherwise approved by the competent authority, the period of use permitted for the carriage of dangerous substances shall be five years from the date of manufacture, except where a shorter period of use is prescribed because of the nature of the substance to be carried. 4.1.1.16. Packages marked in accordance with 6.1.3 but which were approved in a State which is not a Member State may nevertheless be used for carriage under this Directive. 4.1.1.17. Use of salvage packagings 4.1.1.17.1 Damaged, defective or leaking packages containing dangerous goods, or dangerous goods that have spilled or leaked may be carried in salvage packagings in accordance with 6.1.5.1.11. This does not prevent the use of bigger size packagings of appropriate type and performance level under the conditions of 4.1.1.17.2. 4.1.1.17.2 Appropriate measures shall be taken to prevent excessive movement of the damaged or leaking packages within a salvage packaging. When the salvage packaging contains liquids, sufficient inert absorbent material shall be added to eliminate the presence of free liquid. 4.1.2. Additional general requirements for the use of IBC's 4.1.2.1. When IBCs are used for the carriage of liquids with a flash-point of 61 °C (closed cup) or lower, or of powders liable to dust explosion, measures shall be taken to prevent a dangerous electrostatic discharge. 4.1.2.2. The periodic testing and inspection requirements for IBCs are covered in Chapter 6.5. An IBC shall not be filled or handed over for carriage after the date of expiry of the periodic test required by 6.5.4.14.3, or the date of expiry of the periodic inspection required by 6.5.1.6.4. However, an IBC filled prior to the date of expiry of the periodic test or inspection may be carried for a period not to exceed three months beyond the date of expiry of the periodic test or inspection. In addition, an IBC may be carried after the date of expiry of the periodic test or inspection: (a) after emptying but before cleaning, for purposes of performing the next required test or inspection prior to refilling; and (b) unless otherwise specified by the competent authority, for a period not to exceed six months beyond the date of expiry of the last periodic test or inspection in order to allow the return of dangerous goods or residues for proper disposal or recycling. NOTE. For the information in the consignment note, see 5.4.1.1.11. 4.1.2.3. IBCs of type 31HZ2 shall be filled to at least 80 % of the volume of the outer casing and always be carried in covered wagons or closed containers. 4.1.3. General requirements concerning packing instructions 4.1.3.1. Packing Instructions applicable to dangerous goods of Classes 1 to 9 are listed in 4.1.4. They are subdivided into three sub-sections depending on the type of packagings to which they apply: 4.1.4.1 for packagings other than IBCs and large packagings; these Packing Instructions are designated by an alphanumeric code starting with the letter "R" for packagings specific to this Directive and Directive 94/55/EC; 4.1.4.2 for IBCs; these are designated by an alphanumeric code starting with the letters "IBC"; 4.1.4.3 for large packagings; these are designated by an alphanumeric code starting with the letters "LP". Generally, Packing Instructions specify that the general requirements of 4.1.1, 4.1.2 and/or 4.1.3, as appropriate, are applicable. They may also require compliance with the special requirements of 4.1.5, 4.1.6, 4.1.7, 4.1.8 or 4.1.9 when appropriate. Special packing requirements may also be specified in the packing instruction for individual substances or articles. They are also designated by an alphanumeric code comprising the letters: "PP" for packagings other than IBCs and large packagings, or "RR" for special requirements specific to this Directive and Directive 94/55/EC; "B" for IBCs; "L" for large packagings. Unless otherwise specified, each packaging shall conform to the applicable requirements of Part 6. Generally Packing Instructions do not provide guidance on compatibility and the user shall not select a packaging witwood checking that the substance is compatible with the packaging material selected (e.g. glass receptacles are unsuitable for most fluorides). Where glass receptacles are permitted in the packing instructions porcelain and stoneware packagings are also allowed. 4.1.3.2. Column (8) of Table A of Chapter 3.2 shows for each article or substance the Packing Instruction(s) that shall be used. Columns (9a) and (9b) indicate the special packing requirements and the mixed packing requirements (see 4.1.10) applicable to specific substances or articles. 4.1.3.3. Each packing instruction shows, where applicable, the acceptable single and combination packagings. For combination packagings, the acceptable outer packagings, inner packagings and when applicable the maximum quantity permitted in each inner or outer packaging, are shown. Maximum net mass and maximum capacity are as defined in 1.2.1. 4.1.3.4. The following packagings shall not be used when the substances being carried are liable to become liquid during carriage: Packagings Drums: 1D and 1G Boxes: 4A, 4B, 4C1, 4C2, 4D, 4F, 4G, 4H1 and 4H2 Bags: 5L1, 5L2, 5L3, 5H1, 5H2, 5H3, 5H4, 5M1 and 5M2 Composite packagings: 6HC, 6HD2, 6HG1, 6HG2, 6HD1, 6PC, 6PD1, 6PD2, 6PG1, 6PG2 and 6PH1 IBCs For substances of Packing Group I: All types of IBC For substances of Packing Groups II and III: Wooden: 11C, 11D and 11F Fibreboard: 11G Flexible: 13H1, 13H2, 13H3, 13H4, 13H5, 13L1, 13L2, 13L3, 13L4, 13M1 and 13M2 Composite: 11HZ2, 21HZ2 and 31HZ2 For the purposes of this paragraph, substances and mixtures of substances having a melting point equal to or less than 45 °C shall be treated as solids liable to become liquid during carriage. 4.1.3.5. Where the packing instructions in this Chapter authorize the use of a particular type of outer packaging in a combination packaging (e.g. 4G), packagings bearing the same packaging identification code followed by the letters "V", "U" or "W" marked in accordance with the requirements of Part 6 (e.g. 4GV, 4GU or 4GW) may also be used under the same conditions and limitations applicable to the use of that type of outer packaging according to the relevant packing instructions. For example, a combination packaging marked with the packaging code "4GV" may be used whenever a combination packaging marked "4G" is authorized, provided the requirements in the relevant packing instruction regarding types of inner packagings and quantity limitations are respected. 4.1.3.6. Gas cylinders and gas receptacles approved by the competent authority are authorized for the carriage of any liquid or solid substance assigned to Packing Instruction P001 or P002 unless otherwise indicated in the Packing Instruction or by a special requirement in column (9a) of Table A of Chapter 3.2. The capacity of gas cylinders shall not exceed 450 litres. The capacity for gas receptacles shall not exceed 1000 litres. 4.1.3.7. Packagings or IBCs not specifically authorized in the applicable packing instruction shall not be used for the carriage of a substance or article unless specifically allowed under a temporary derogation agreed between Member States in accordance with 1.5.1. 4.1.4.

Tabel A List of Particular Requirements (PR) for gas cylinders and receptacles >TABLE> 4.1.5. Special packing provisions for goods of class 1 4.1.5.1. The general provisions of section 4.1.1 shall be met. 4.1.5.2. All packagings for Class 1 goods shall be so designed and constructed that: (a) They will protect the explosives, prevent them escaping and cause no increase in the risk of unintended ignition or initiation when subjected to normal conditions of carriage including foreseeable changes in temperature, humidity and pressure; (b) The complete package can be handled safely in normal conditions of carriage; and (c) The packages will withstand any loading imposed on them by foreseeable stacking to which they will be subject during carriage so that they do not add to the risk presented by the explosives, the containment function of the packagings is not harmed, and they are not distorted in a way or to an extent which will reduce their strength or cause instability of a stack. 4.1.5.3. All explosive substances and articles, as prepared for carriage, shall have been classified in accordance with the procedures detailed in 2.2.1. 4.1.5.4. Class 1 goods shall be packed in accordance with the appropriate Packing Instruction shown in Column 8 of Table A of Chapter 3.2, as detailed in 4.1.4. 4.1.5.5. Packagings, including IBCs and large packagings shall conform to the requirements of Chapter 6.1, 6.5 or 6.6, respectively, and shall meet the test requirements of 6.1.5, 6.5.4 or 6.6.5, respectively, for Packing Group II, subject to 4.1.1.13, 6.1.2.4 and 6.5.1.4.4. Packagings other than metal packagings meeting the test criteria of Packing Group I may be used. To avoid unnecessary confinement, metal packagings of Packing Group I shall not be used. 4.1.5.6. The closure device of packagings containing liquid explosives shall ensure a double protection against leakage. 4.1.5.7. The closure device of metal drums shall include a suitable gasket; if a closure device includes a screw-thread, the ingress of explosive substances into the screw-thread shall be prevented. 4.1.5.8. Packagings for water soluble substances shall be water resistant. Packagings for desensitized or phlegmatized substances shall be closed to prevent changes in concentration during carriage. 4.1.5.9. (Reserved) 4.1.5.10. Nails, staples and other closure devices made of metal without protective covering shall not penetrate to the inside of the outer packaging unless the inner packaging adequately protects the explosives against contact with the metal. 4.1.5.11. Inner packagings, fittings and cushioning materials and the placing of explosive substances or articles in packages shall be accomplished in a manner which prevents the explosive substances or articles from becoming loose in the outer packaging under normal conditions of carriage. Metallic components of articles shall be prevented from making contact with metal packagings. Articles containing explosive substances not enclosed in an outer casing shall be separated from each other in order to prevent friction and impact. Padding, trays, partitioning in the inner or outer packaging, mouldings or receptacles may be used for this purpose. 4.1.5.12. Packagings shall be made of materials compatible with, and impermeable to, the explosives contained in the package, so that neither interaction between the explosives and the packaging materials, nor leakage, causes the explosive to become unsafe for carriage, or the hazard division or compatibility group to change. 4.1.5.13. The ingress of explosive substances into the recesses of seamed metal packagings shall be prevented. 4.1.5.14. Plastics packagings shall not be liable to generate or accumulate sufficient static electricity so that a discharge could cause the packaged explosive substances or articles to initiate, ignite or function. 4.1.5.15. Large and robust explosives articles, normally intended for military use, without their means of initiation or with their means of initiation containing at least two effective protective features, may be carried unpackaged. When such articles have propelling charges or are self-propelled, their ignition systems shall be protected against stimuli encountered during normal conditions of carriage. A negative result in Test Series 4 on an unpackaged article indicates that the article can be considered for carriage unpackaged. Such unpackaged articles may be fixed to cradles or contained in crates or other suitable handling, storage or launching devices in such a way that they will not become loose during normal conditions of carriage. Where such large explosive articles are as part of their operational safety and suitability tests subjected to test regimes that meet the intentions of this Directive and such tests have been successfully undertaken, the competent authority may approve such articles to be carried under this Directive. 4.1.5.16. Explosive substances shall not be packed in inner or outer packagings where the differences in internal and external pressures, due to thermal or other effects, could cause an explosion or rupture of the package. 4.1.5.17. Whenever loose explosive substances or the explosive substance of an uncased or partly cased article may come into contact with the inner surface of metal packagings (1A2, 1B2, 4A, 4B and metal receptacles), the metal packaging shall be provided with an inner liner or coating (see 4.1.1.2). 4.1.5.18. Packing instruction P101 may be used for any explosive provided the packaging has been approved by a competent authority regardless of whether the packaging complies with the packing instruction assignment in column 8 of Table A of Chapter 3.2. 4.1.6. Special packing provisions for goods of Class 2 4.1.6.1. Receptacles, including their closures, shall be selected to contain a gas or a mixture of gases according to the requirements of 6.2.1.2 "Materials of receptacles" and the requirements of the relevant packing instructions of 4.1.4. 4.1.6.2. A change of use of a refillable receptacle shall include emptying, purging and evacuation operations to the extent necessary for safe operation (see also table of standards at the end of this section). NOTE 1. Refillable receptacles for the carriage of gases of Class 2 shall be periodically inspected according to the periodicity set out in the relevant Packing Instructions (P200 or P203) and according to the provisions detailed in 6.2.1.6 "Periodic inspection". NOTE 2. Receptacles ready for consignment shall be marked and labelled according to the provisions set out in Chapter 5.2 4.1.6.3. Receptacles except open cryogenic receptacles, including their closures, shall conform to the design, construction, inspection and testing requirements detailed in Chapter 6.2. When outer packagings are prescribed, the receptacles shall be firmly secured therein. Unless otherwise specified in the relevant packing instructions, receptacles may be enclosed in outer packagings either singly or in groups. 4.1.6.4. Valves (cocks) shall be effectively protected from damage which could cause gas release if the receptacle falls, and during carriage and stacking. This requirement is deemed to be complied with if one or more of the following conditions are fulfilled (see also table of standards at the end of this section): (a) Valves are placed inside the neck of the receptacle and protected by a screw-threaded plug; (b) Valves are protected by caps. Caps shall possess vent-holes of sufficient cross-sectional area to evacuate gases if leakage occurs at the valves; (c) Valves are protected by shrouds or other protective devices; (d) Valves are designed and constructed in such a way that they are capable of withstanding damage without leakage; (e) Valves are placed inside a protective frame; (f) Receptacles are carried in protective boxes or frames. 4.1.6.5. Receptacles, containing pyrophoric gases or very toxic gases (gases with an LC50 lower than 200 ppm) shall have their valve(s) openings fitted with gas-tight plugs or cap nuts which shall be made of a material not liable to attack by the contents of the receptacle. 4.1.6.6. Receptacles may be carried after the expiry of the time-limit set for the periodic test prescribed for the purpose of undergoing the test. 4.1.6.7. Requirements of the following packing provisions are considered to have been complied with if the following standards, as relevant, are applied: >TABLE> 4.1.7.

For tank wagons, wagons with demountable tanks, tank-containers and tank swap bodies with shells made of metallic materials, as well as battery wagons and multiple element gas containers (MEGCs), see Chapter 4.3; for tank-containers made of fibre-reinforced plastics, see Chapter 4.4. 4.2.1. General provisions for the use of portable tanks for the carriage of substances of Classes 3 to 9 4.2.1.1. This section provides general requirements applicable to the use of portable tanks for the carriage of substances of Classes 3, 4.1, 4.2, 4.3, 5.1, 5.2, 6.1, 6.2, 7, 8 and 9. In addition to these general requirements, portable tanks shall conform to the design, construction and testing requirements detailed in 6.7.2. Substances shall be carried in portable tanks conforming to the applicable portable tank instruction identified in Column 10 of table A of Chapter 3.2 and described in 4.2.4.2.6 (T1 to T23) and the portable tank special provisions described in 4.2.4.3 assigned to each substance in Column 11 of table A of Chapter 3.2. 4.2.1.2. During carriage, portable tanks shall be adequately protected against damage to the shell and service equipment resulting from lateral and longitudinal impact and overturning. If the shell and service equipment are so constructed as to withstand impact or overturning it need not be protected in this way. Examples of such protection are given in 6.7.2.17.5. 4.2.1.3. Certain substances are chemically unstable. They are accepted for carriage only when the necessary steps have been taken to prevent their dangerous decomposition, transformation or polymerization during carriage. To this end, care shall in particular be taken to ensure that shells do not contain any substances liable to promote these reactions. 4.2.1.4. The temperature of the outer surface of the shell excluding openings and their closures or of the thermal insulation shall not exceed 70 °C during carriage. When dangerous goods are carried at elevated temperatures in either liquid or solid state, the shell shall be thermally insulated to meet this condition. 4.2.1.5. Empty portable tanks not cleaned and not gas-free shall comply with the same requirements as portable tanks filled with the previous substance. 4.2.1.6. Substances shall not be carried in the same or adjoining compartments of shells when they may react dangerously (see definition of dangerous reaction in 1.2.1) with each other. 4.2.1.7. The design approval certificate, the test report and the certificate showing the results of the initial inspection and test for each portable tank issued by the competent authority or its authorized body shall be retained by the authority or body and the owner. Owners shall be able to provide this documentation upon the request of any competent authority. 4.2.1.8. Unless the name of the substance(s) being carried appears on the metal plate described in 6.7.2.20.2, a copy of the certificate specified in 6.7.2.18.1 shall be made available upon the request of a competent authority or its authorized body and readily provided by the consignor, consignee or agent, as appropriate. 4.2.1.9. Degree of filling 4.2.1.9.1. Prior to filling, the filler shall ensure that the appropriate portable tank is used and that the portable tank is not loaded with substances which in contact with the materials of the shell, gaskets, service equipment and any protective linings, are likely to react dangerously with them to form dangerous products or appreciably weaken the material. The filler may need to consult the manufacturer of the substance in conjunction with the competent authority for guidance on the compatibility of the substance with the portable tank materials. 4.2.1.9.1.1 Portable tanks shall not be filled above the extent provided in 4.2.1.9.2 to 4.2.1.9.6. The applicability of 4.2.1.9.2, 4.2.1.9.3 or 4.2.1.9.5.1 to individual substances is specified in the applicable portable tank instructions or portable tank special provisions in 4.2.4.2.6 or 4.2.4.3 and Column 10 or 11 of table A of Chapter 3.2. 4.2.1.9.2. The maximum degree of filling (in %) for general use is determined by the formula: >REFERENCE TO A GRAPHIC> 4.2.1.9.3. The maximum degree of filling (in %) for liquids of Class 6.1 and Class 8, in Packing Groups I and II, and liquids with an absolute vapour pressure of more than 175 kPa (1,75 bar) at 65 °C, is determined by the formula: >REFERENCE TO A GRAPHIC> 4.2.1.9.4. In these formulae, α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (tf) and the maximum mean bulk temperature during carriage (tr) (both in °C). For liquids carried under ambient conditions α could be calculated by the formula: >REFERENCE TO A GRAPHIC> in which d15 and d50 are the densities of the liquid at 15 °C and 50 °C, respectively. 4.2.1.9.4.1 The maximum mean bulk temperature (tr) shall be taken as 50 °C except that, for journeys under temperate or extreme climatic conditions, the competent authorities concerned may agree to a lower or require a higher temperature, as appropriate. 4.2.1.9.5. The requirements of 4.2.1.9.2 to 4.2.1.9.4.1 do not apply to portable tanks which contain substances maintained at a temperature above 50 °C during carriage (e.g. by means of a heating device).

General 4.2.4.1.1 This section includes the portable tank instructions and special requirements applicable to dangerous goods authorized to be carried in portable tanks. Each portable tank instruction is identified by an alpha-numeric code (e.g. T1). Column 10 of table A of Chapter 3.2 indicates the portable tank instruction that shall be used for each substance permitted for carriage in a portable tank. When no portable tank instruction appears in Column 10 for a specific dangerous goods entry then carriage of the substance in portable tanks is not permitted unless a competent authority approval is granted as detailed in 6.7.1.3. Portable tank special requirements are assigned to specific dangerous goods in Column 11 of table A of Chapter 3.2. Each portable tank special requirement is identified by an alphanumeric code (e.g. TP1). A listing of the portable tank special requirements is provided in 4.2.4.3. 4.2.4.2. Portable tank instructions 4.2.4.2.1. Portable tank instructions apply to substances of Classes 2 to 9. Portable tank instructions provide specific information relevant to portable tank requirements applicable to specific substances. These requirements shall be met in addition to the general requirements in this Chapter and Chapter 6.7. 4.2.4.2.2. For substances of Classes 3 to 9, the portable tank instructions indicate the applicable minimum test pressure, the minimum shell thickness (in reference steel), bottom opening requirements and pressure relief requirements. In T23, self-reactive substances of Class 4.1 and organic peroxides of Class 5.2 permitted to be carried in portable tanks are listed. 4.2.4.2.3. Non-refrigerated liquefied gases are assigned to portable tank instruction T50. T50 provides the maximum allowable working pressures, requirements for openings below the level of the liquid, pressure relief requirements and maximum degree of filling requirements for non-refrigerated liquefied gases permitted for carriage in portable tanks. 4.2.4.2.4. Refrigerated liquefied gases are assigned to portable tank instruction T75. 4.2.4.2.5. Determination of the appropriate portable tank instruction When a specific portable tank instruction is specified in Column 10 for a specific substance additional portable tanks which possess minimum test pressures, greater wall thicknesses, more stringent bottom opening and pressure-relief device arrangements may be used. The following guidelines apply to determining the appropriate portable tanks which may be used for the carriage of particular substances: >TABLE> 4.2.4.2.6.

Use 4.3.2.1.1 A substance subject to this Directive may be carried in tank-wagons, demountable tanks, batterywagons, tank-containers, tank swap bodies and MEGCs only when provision is made for a tank code according to 4.3.3.1.1 and 4.3.4.1.1 in column (12) of Table A in Chapter 3.2. 4.3.2.1.2 The required type of tank, battery-wagon and MEGC is given in code form in column (12) of Table A in Chapter 3.2. The identification codes appearing there are made up of letters and numbers in a given order. The explanations for reading the four parts of the code are given in 4.3.3.1.1 (when the substance to be carried belongs to Class 2) and in 4.3.4.1.1 (when the substance to be carried belongs to Classes 3 to 9)(22) 4.3.2.1.3 The required type according to 4.3.2.1.2 corresponds to the least stringent construction requirements which are acceptable for the dangerous substance in question unless otherwise prescribed in this chapter or in chapter 6.8. It is possible to use tanks corresponding to codes prescribing a higher minimum calculation pressure, or more stringent requirements for filling or discharge openings or for safety valves/devices (see 4.3.3.1.1 for Class 2 and 4.3.4.1.1 for Classes 3 to 9). 4.3.2.1.4 For certain substances, tanks, battery-wagons or MEGCs are subject to additional requirements which are included as special provisions in column (13) of Table A in Chapter 3.2. 4.3.2.1.5 Tanks, battery-wagons and MEGCs shall not be loaded with any dangerous substances other than those for the carriage of which they have been approved (see 6.8.2.3.1) and which, in contact with the materials of the shell, gaskets, equipment and protective linings, are not liable to react dangerously with them (see definition of "dangerous reaction" in 1.2.1), to form dangerous products or appreciably to weaken these materials(23). 4.3.2.1.6 Foodstuffs shall not be carried in tanks used for dangerous substances unless the necessary steps have been taken to prevent any harm to public health. 4.3.2.2. Degree of filling 4.3.2.2.1 The following degrees of filling shall not be exceeded in tanks intended for the carriage of liquids at ambient temperatures: (a) for flammable substances without additional risks (e.g. toxicity or corrosivity), in tanks with a venting system or with safety valves (even where preceded by a bursting disc): >REFERENCE TO A GRAPHIC> (b) for toxic or corrosive substances (whether flammable or not) in tanks with a venting system or with safety valves (even where preceded by a bursting disc): >REFERENCE TO A GRAPHIC> (c) for flammable substances and for slightly toxic or corrosive substances (whether flammable or not) in hermetically closed tanks without a safety device: >REFERENCE TO A GRAPHIC> (d) for highly toxic, toxic, highly corrosive or corrosive substances (whether flammable or not) in hermetically closed tanks without a safety device: >REFERENCE TO A GRAPHIC> 4.3.2.2.2 In these formulae, is the mean coefficient of cubical expansion of the liquid between 15 °C and 50 °C, i.e. for a maximum variation in temperature of 35 °C.α is calculated by the formula: >REFERENCE TO A GRAPHIC> where d15 and d50 are the relative densities of the liquid at 15 °C and 50 °C respectively and tF is the mean temperature of the liquid during filling. 4.3.2.2.3 The requirements of 4.3.2.2.1 (a) to (d) above shall not apply to tanks whose contents are, by means of a heating device, maintained at a temperature above 50 °C during carriage. In this case the degree of filling at the outset shall be such, and the temperature so regulated, that the tank is not full to more than 95 % of its capacity and that the filling temperature is not exceeded during carriage. 4.3.2.2.4 >TABLE> 4.3.2.3. Operation 4.3.2.3.1. The thickness of the walls of the shell shall not, throughout its use, fall below the minimum figure prescribed in >TABLE> 4.3.2.3.2. >TABLE> 4.3.2.3.3. During filling and discharge of tanks, battery-wagons and MEGCs, appropriate measures shall be taken to prevent the release of dangerous quantities of gases and vapours. Tanks, battery-wagons and MEGCs shall be closed so that the contents cannot spill out uncontrolled. The openings of bottom-discharge tanks shall be closed by means of screwthreaded plugs, blank flanges or other equally effective devices. The leakproofness of the closures of the tanks, and of the battery-wagons and MEGCs shall be checked by the filler after the tank is filled. This applies in particular to the upper part of the dip tube. 4.3.2.3.4. Where several closure systems are fitted in series, that nearest to the substance being carried shall be closed first. 4.3.2.3.5. No dangerous residue of the filling substance shall adhere to the outside of the tank during carriage. 4.3.2.3.6. Substances which may react dangerously with each other shall not be carried in adjoining compartments of tanks. Substances which may react dangerously with each other may be carried in adjoining compartments of tanks, when these compartments are separated by a partition with a wall thickness equal to or greater than that of the tank itself. They may also be carried separated by an empty space or an empty compartment between loaded compartments. 4.3.2.4. Empty tanks, battery-wagons and MEGCs, uncleaned NOTE. For empty tanks, battery-wagons and MEGCs, uncleaned, special provisions TU1, TU2, TU4, TU16 and TU35 of section 4.3.5 may apply. 4.3.2.4.1 No dangerous residue of the filling substance shall adhere to the outside of the tank during carriage. 4.3.2.4.2 Empty tanks, battery-wagons and MEGCs, uncleaned, shall be closed in the same manner and be leakproof to the same degree as if they were full. 4.3.2.4.3 Where empty tanks, battery-wagons and MEGCs, uncleaned, are not closed in the same manner and are not leakproof to the same degree as if they were full and where the requirements of RID cannot be complied with, they shall be carried, with due regard to adequate safety, to the nearest suitable place where cleaning or repair can be carried out. Carriage is adequately safe if suitable measures have been taken to ensure equivalent safety commensurate with the requirements of this Directive and to prevent the uncontrolled release of the dangerous goods. 4.3.2.4.4 Empty fixed tank-wagons, demountable tanks, battery-wagons, tank-containers, tank swap bodies and MEGCs, uncleaned, may also be carried after the expiry of the periods established in 6.8.2.4.2 and 6.8.2.4.3 for undergoing the inspection. 4.3.3.

Hierarchy of tanks >TABLE> The figure represented by shall be equal to or greater than the figure represented by *. NOTE. This hierarchy does not take any special provisions into account (see 4.3.5 and 6.8.4) for each entry. 4.3.3.2. Filling conditions and test pressures 4.3.3.2.1. The test pressure for tanks intended for the carriage of compressed gases having a critical temperature below -50 °C shall be at least one and one half times the filling pressure at 15 °C. 4.3.3.2.2. The test pressure for tanks intended for the carriage of: - compressed gases having a critical temperature of -50 °C or above; - liquefied gases having a critical temperature below 70 °C; and - gases dissolved under pressure shall be such that, when the shell is filled to the maximum mass of the contents per litre of capacity, the pressure reached in the shell by the substance at 55 °C for tanks with thermal insulation or 65 °C for tanks without thermal insulation does not exceed the test pressure. 4.3.3.2.3. The test pressure for tanks intended for the carriage of liquefied gases having a critical temperature of 70 °C or above shall be: (a) If the tank is equipped with thermal insulation, at least equal to the vapour pressure, reduced by 0,1 MPa (1 bar) of the liquid at 60 °C, but not less than 1 MPa (10 bar); (b) If the tank is not equipped with thermal insulation, at least equal to the vapour pressure, reduced by 0,1 MPa (1 bar), of the liquid at 65 °C, but not less than 1 MPa (10 bar). The maximum permissible mass of contents per litre of capacity in kg/l for the degree of filling is calculated as follows: Maximum permissible mass of contents per litre of capacity = 0,95 x density of the liquid phase at 50 °C (in kg/l); moreover the vapour phase shall not disappear below 60 °C. If the shells are not more than 1,5 m in diameter the values of the test pressure and maximum permissible mass of contents per litre of capacity conforming to Packing Instruction P200 in 4.1.4.1 shall be applicable. 4.3.3.2.4. The test pressure for tanks intended for the carriage of liquefied refrigerated gases shall be not less than 1,3 times the maximum permitted working pressure indicated on the tank but not less than 300 kPa (3 bar) (gauge pressure); for tanks with vacuum insulation the test pressure shall be not less than 1,3 times the maximum permitted working pressure increased by 100 kPa (1 bar). 4.3.3.2.5.

Unless an infectious substance cannot be consigned by any other means, live vertebrate or invertebrate animals shall not be used to consign such a substance. Such animals shall be packed, marked, labelled and carried in accordance with the relevant regulations governing the carriage of animals(30). 5.5.1.2. The carriage of infectious substances of risk groups 3 and 4 requires coordinated action by the consignor, the carrier and the consignee to ensure safety and arrival on time and in proper condition. To this end, the following measures shall be taken: (a) Advance arrangements between consignor, carrier and consignee. Dispatch of infectious substances shall not take place before advance arrangements have been made between consignor, carrier and consignee or before the consignee has confirmed with his competent authorities that the substances can legally be imported and that no delay will be incurred in the delivery of the consignment to its destination; (b) Preparation of dispatch documents. In order to secure transmission without hindrance it is necessary to prepare all dispatch documents, including the consignment note (see Chapter 5.4), in strict accordance with rules governing the acceptance of the goods to be dispatched; (c) Routeing. Whatever the mode used, transport shall be by the quickest possible routeing. If transshipment is necessary, precautions shall be taken to ensure special care, expeditious handling and monitoring of the substances in transit; (d) Timely notification of all transport data by consignor to consignee. The consignor shall notify the consignee in advance of transport details, such as: means of transport, train number(s), consignment note number and date and hour of expected arrival at the point of destination, so that the consignment can be collected promptly. The most rapid means of communication shall be used for this notification. 5.5.1.3. Dead animals which are known or reasonably believed to contain an infectious substance shall be packed, marked, labelled and carried in accordance with the conditions(31) specified by the competent authority of the country of origin(32). 5.5.2. Special requirements for fumigated wagons or containers 5.5.2.1. Consignment notes associated with containers and wagons that have been fumigated shall show the date of fumigation and the type and amount of the fumigant used. In addition, instructions for disposal of any residual fumigant including fumigation devices (if used) shall be provided. These instructions shall be in an official language of the forwarding country and, if this language is not French, German, Italian or English, in French, German, Italian or English, unless international tariffs or agreements between the railways provide otherwise. 5.5.2.2. A warning sign as specified in the figure below shall be placed on each fumigated container or wagon in a location where it will be easily seen by persons attempting to enter the interior of the container or wagon. The information on the warning sign shall be in a language the consignor considers suitable. >PIC FILE= "L_2004121EN.069301.TIF"> Part 6 REQUIREMENTS FOR THE CONSTRUCTION AND TESTING OF PACKAGINGS, INTERMEDIATE BULK CONTAINERS (IBCS), LARGE PACKAGINGS AND TANKS CHAPTER 6.1 Requirements for the construction and testing of packagings 6.1.1. General 6.1.1.1. The requirements of this Chapter do not apply to: (a) packages containing radioactive material of Class 7, unless otherwise provided (see 4.1.9.1.5); (b) packages containing infectious substances of Class 6.2, unless otherwise provided (see 4.1.8.2); (c) receptacles containing gases of Class 2; (d) packages whose net mass exceeds 400 kg; (e) packagings with a capacity exceeding 450 litres. 6.1.1.2. The requirements in 6.1.4 are based on packagings currently used. In order to take into account progress in science and technology, there is no objection to the use of packagings having specifications different from those in 6.1.4, provided that they are equally effective, acceptable to the competent authority and able successfully to withstand the tests described in 6.1.1.3 and 6.1.5. Methods of testing other than those described in this Chapter are acceptable, provided they are equivalent, and are recognized by the competent authority. 6.1.1.3. Every packaging intended to contain liquids shall successfully undergo a suitable leakproofness test, and be capable of meeting the appropriate test level indicated in 6.1.5.4.3: (a) before it is first used for carriage; (b) after remanufacturing or reconditioning, before it is re-used for carriage; For this test, packagings need not have their own closures fitted. The inner receptacle of composite packagings may be tested without the outer packaging provided the test results are not affected. This test is not necessary for: - inner packagings of combination packagings; - inner receptacles of composite packagings (glass, porcelain or stoneware), marked with the symbol "RID/ADR" according to 6.1.3.1 (a)(ii); - light gauge metal packagings, marked with the symbol "RID/ADR" according to 6.1.3.1 (a)(ii). 6.1.1.4. Packagings shall be manufactured and tested under a quality assurance programme which satisfies the competent authority in order to ensure that each manufactured packaging meets the requirements of this Chapter. 6.1.2. Code for designating types of packagings 6.1.2.1. The code consists of: (a) an Arabic numeral indicating the kind of packaging, e.g. drum, jerrican, etc., followed by; (b) a capital letter(s) in Latin characters indicating the nature of the material, e.g. steel, wood, etc., followed where necessary by; (c) an Arabic numeral indicating the category of packaging within the kind to which the packaging belongs. 6.1.2.2. In the case of composite packagings, two capital letters in Latin characters are used in sequence in the second position of the code. The first indicates the material of the inner receptacle and the second that of the outer packaging. 6.1.2.3. In the case of combination packagings and infectious substances packagings marked in accordance with 6.3.1.1, only the code number for the outer packaging is used. 6.1.2.4. The letters "T", "V" or "W" may follow the packaging code. The letter "T" signifies a salvage packaging conforming to the requirements of 6.1.5.1.11. The letter "V" signifies a special packaging conforming to the requirements of 6.1.5.1.7. The letter "W" signifies that the packaging, although of the same type indicated by the code, is manufactured to a specification different to that in 6.1.4 and is considered equivalent under the requirements of 6.1.1.2. 6.1.2.5. The following numerals shall be used for the kinds of packaging: 1. Drum 2. Wooden barrel 3. Jerrican 4. Box 5. Bag 6. Composite packaging 7. (reserved) 0. Light gauge metal packaging 6.1.2.6. The following capital letters shall be used for the types of material: A. Steel (all types and surface treatments) B. Aluminium C. Natural wood D. Plywood F. Reconstituted wood G. Fibreboard H. Plastics material L. Textile M. Paper, multiwall N. Metal (other than steel or aluminium) P. Glass, porcelain or stoneware 6.1.2.7. The following table indicates the codes to be used for designating types of packagings depending on the kind of packagings, the material used for their construction and their category; it also refers to the sub-sections to be consulted for the appropriate requirements: >TABLE> 6.1.3. Marking NOTES: 1. The marking indicates that the packaging which bears it corresponds to a successfully tested design type and that it complies with the requirements of this Chapter which are related to the manufacture, but not to the use, of the packaging. In itself, therefore, the mark does not necessarily confirm that the packaging may be used for any substance: generally the type of packaging (e.g. steel drum), its maximum capacity and/or mass, and any special requirements are specified for each substance in Table A of Chapter 3.2. 2. The marking is intended to be of assistance to packaging manufacturers, reconditioners, packaging users, carriers and regulatory authorities. In relation to the use of a new packaging, the original marking is a means for its manufacturer(s) to identify the type and to indicate those performance test regulations that have been met. 3. The marking does not always provide full details of the test levels, etc., and these may need to be taken further into account, e.g. by reference to a test certificate, to test reports or to a register of successfully tested packagings. For example, a packaging having an X or Y marking may be used for substances to which a packing group having a lesser degree of danger has been assigned with the relevant maximum permissible value of the relative density(33) determined by taking into account the factor 1.5 or 2.25 indicated in the packaging test requirements in 6.1.5 as appropriate, i.e. Group I packaging tested for products of relative density 1.2 could be used as a Group II packaging for products of relative density 1.8 or a Group III packaging for products of relative density 2.7, provided of course that all the performance criteria can still be met with the higher relative density product. 6.1.3.1. Each packaging intended for use according to this Directive shall bear markings which are durable, legible and placed in a location and of such a size relative to the packaging as to be readily visible. For packages with a gross mass of more than 30 kg, the markings or a duplicate thereof shall appear on the top or on a side of the packaging. Letters, numerals and symbols shall be at least 12 mm high, except for packagings of 30 litres or 30 kg capacity or less, when they shall be at least 6 mm in height and for packagings of 5 litres or 5 kg or less when they shall be of an appropriate size. The marking shall show: (a) (i) The United Nations packaging symbol >PIC FILE= "L_2004121EN.069801.TIF"> This shall not be used for any purpose other than certifying that a packaging complies with the relevant requirements in this Chapter. For embossed metal packagings the capital letters "UN" may be applied instead of the symbol; or (ii) The symbol "RID/ADR" for packagings approved for rail transport as well as road transport. For composite packagings (glass, porcelain or stoneware) and light gauge metal packagings, conforming to simplified conditions (see 6.1.1.3, 6.1.5.3.1 (e), 6.1.5.3.4 (c), 6.1.5.4, 6.1.5.5.1 and 6.1.5.6); (b) The code designating the type of packaging according to 6.1.2; (c) A code in two parts: (i) a letter designating the packing group(s) for which the design type has been successfully tested: X for packing groups I, II and III; Y for packing groups II and III; Z for packing group III only; (ii) the relative density, rounded off to the first decimal, for which the design type has been tested for packagings without inner packagings intended to contain liquids; this may be omitted when the relative density does not exceed 1.2. For packagings intended to contain solids or inner packagings, the maximum gross mass in kilograms. For light-gauge metal packagings, marked with the symbol "RID/ADR" according to 6.1.3.1 (a)(ii) intended to contain substances having a viscosity at 23 °C exceeding 200 mm2/s, the maximum gross mass in kg; (d) Either the letter "S" denoting that the packaging is intended for the carriage of solids or inner packagings or, for packagings (other than combination packagings) intended to contain liquids, the hydraulic test pressure which the packaging was shown to withstand in kPa rounded down to the nearest 10 kPa. For light-gauge metal packagings, marked with the symbol "RID/ADR, according to" 6.1.3.1(a)(ii) intended to contain liquids having a viscosity at 23 °C exceeding 200 mm2/s, the letter "S"; NOTE: The requirements of subparagraph (d) do not apply to packagings intended for the carriage of substances classified under UN Nos. 2814 or 2900 of Class 6.2. (e) The last two digits of the year during which the packaging was manufactured. Packagings of types lH and 3H shall also be appropriately marked with the month of manufacture; this may be marked on the packaging in a different place from the remainder of the marking. An appropriate method is: >PIC FILE= "L_2004121EN.069802.TIF"> (f) Requirements for the construction of packagings and the tests to which they will be submitted sign for motor vehicles in international traffic(34); (g) The name of the manufacturer or other identification of the packaging specified by the competent authority. 6.1.3.2. Every reusable packaging liable to undergo a reconditioning process which might obliterate the packaging markings shall bear the marks indicated in 6.1.3.1 (a) to (e) in a permanent form. Marks are permanent if they are able to withstand the reconditioning process (e.g. embossed). For packagings other than metal drums of a capacity greater than 100 litres, these permanent marks may replace the corresponding durable markings prescribed in 6.1.3.1. 6.1.3.2.1. In addition to the durable markings prescribed in 6.1.3.1, every new metal drum of a capacity greater than 100 litres shall bear the marks described in 6.1.3.1 (a) to (e) on the bottom, with an indication of the nominal thickness of at least the metal used in the body (in mm, to 0,1 mm), in permanent form. When the nominal thickness of either head of a metal drum is thinner than that of the body, the nominal thickness of the top head, body, and bottom head shall be marked on the bottom in permanent form (e.g. embossed), for example "1.0-1.2-1.0" or "0.9-1.0-1.0". Nominal thickness of metal shall be determined according to the appropriate ISO standard, for example ISO 3574:1986 for steel. The marks indicated in 6.1.3.1 (f) and (g) shall not be applied in a permanent form except as provided in 6.1.3.2.3. 6.1.3.2.2. For remanufactured metal drums, if there is no change to the packaging type and no replacement or removal of integral structural components, the required markings need not be permanent. Every other remanufactured metal drum shall bear the markings in 6.1.3.1 to (e) in a permanent form on the top head or side. 6.1.3.2.3. Metal drums made from materials (e.g. stainless steel) designed to be reused repeatedly may bear the markings indicated in 6.1.3.1 (f) and (g) in a permanent form (e.g. embossed). 6.1.3.2.4. The marking in accordance with 6.1.3.1 is valid for only one design type or series of design types. Different surface treatments may fall within the same design type. A "series of design types" means packagings of the same structural design, wall thickness, material and cross-section, which differ only in their lesser design heights from the design type approved. The closures of receptacles shall be identifiable as those referred to in the test report. 6.1.3.3. Marking shall be applied in the sequence of the subparagraphs in 6.1.3.l (for examples, see 6.1.3.7). Any additional markings authorized by a competent authority shall still enable the parts of the mark to be correctly identified with reference to 6.1.3.l. 6.1.3.4. After reconditioning a packaging, the reconditioner shall apply to it a durable marking showing, in the following sequence: (h) The State in which the reconditioning was carried out, indicated by the distinguishing sign for motor vehicles in international traffic (1); (i) The name or authorized symbol of the reconditioner; (j) The year of reconditioning; the letter "R"; and, for every packaging successfully passing the leakproofness test in 6.1.1.3, the additional letter "L". 6.1.3.5. When, after reconditioning, the markings required by 6.1.3.1 (a) to (d) no longer appear on the top head or the side of a metal drum, the reconditioner also shall apply them in a durable form followed by 6.1.3.4 (h), (i) and (j). These markings shall not identify a greater performance capability than that for which the original design type had been tested and marked. 6.1.3.6. Packagings manufactured with recycled plastics material as defined in 1.2.1 shall be marked "REC". This mark shall be placed near the mark prescribed in 6.1.3.1. 6.1.3.7. Examples of markings for NEW packagings >TABLE> 6.1.3.8. Examples of markings for RECONDITIONED packagings >TABLE> 6.1.3.9. Example of marking for SALVAGE packagings >TABLE> NOTE: The markings, for which examples are given in 6.1.3.7, 6.1.3.8 and 6.1.3.9 may be applied in a single line or in multiple lines provided the correct sequence is respected. 6.1.3.10.

The maximum permissible permeability for flammable liquids shall be 0,008 g/l.h at 23 °C (see 6.1.5.8). 6.1.4.8.8. Where recycled plastics material is used for production of new packaging, the specific properties of the recycled material shall be assured and documented regularly as part of a quality assurance programme recognised by the competent authority. The quality assurance programme shall include a record of proper pre-sorting and verification that each batch of recycled plastics material has the proper melt flow rate, density, and tensile yield strength, consistent with that of the design type manufactured from such recycled material. This necessarily includes knowledge about the packaging material from which the recycled plastics have been derived, as well as the awareness of the prior contents of those packagings if those prior contents might reduce the capability of new packaging produced using that material.

The design type of each packaging shall be tested as provided in 6.1.5 in accordance with procedures established by the competent authority. 6.1.5.1.2. Tests shall be successfully performed on each packaging design type before such packaging is used. A packaging design type is defined by the design, size, material and thickness, manner of construction and packing, but may include various surface treatments. It also includes packagings which differ from the design type only in their lesser design height. 6.1.5.1.3. Tests shall be repeated on production samples at intervals established by the competent authority. For such tests on paper or fibreboard packagings, preparation at ambient conditions is considered equivalent to the requirements of 6.1.5.2.3. 6.1.5.1.4. Tests shall also be repeated after each modification which alters the design, material or manner of construction of a packaging. 6.1.5.1.5. The competent authority may permit the selective testing of packagings that differ only in minor respects from a tested type, e.g. smaller sizes of inner packagings or inner packagings of lower net mass; and packagings such as drums, bags and boxes which are produced with small reductions in external dimension(s). 6.1.5.1.6. Where an outer packaging of a combination packaging has been successfully tested with different types of inner packagings, a variety of such different inner packagings may also be assembled in this outer packaging. In addition, provided an equivalent level of performance is maintained, the following variations in inner packagings are allowed without further testing of the package: (a) Inner packagings of equivalent or smaller size may be used provided: (i) the inner packagings are of similar design to the tested inner packagings (e.g. shape - round, rectangular, etc.); (ii) the material of construction of the inner packagings (glass, plastics, metal, etc.) offers resistance to impact and stacking forces equal to or greater than that of the originally tested inner packaging; (iii) the inner packagings have the same or smaller openings and the closure is of similar design (e.g. screw cap, friction lid, etc.); (iv) sufficient additional cushioning material is used to take up void spaces and to prevent significant movement of the inner packagings; (v) inner packagings are oriented within the outer packaging in the same manner as in the tested package. (b) A lesser number of the tested inner packagings, or of the alternative types of inner packagings identified in (a) above, may be used provided sufficient cushioning is added to fill the void space(s) and to prevent significant movement of the inner packagings. 6.1.5.1.7. Articles or inner packagings of any type for solids or liquids may be assembled and carried without testing in an outer packaging under the following conditions: (a) The outer packaging shall have been successfully tested in accordance with 6.1.5.3 with fragile (e.g. glass) inner packagings containing liquids using the packing group I drop height; (b) The total combined gross mass of inner packagings shall not exceed one half the gross mass of inner packagings used for the drop test in (a) above; (c) The thickness of cushioning material between inner packagings and between inner packagings and the outside of the packaging shall not be reduced below the corresponding thicknesses in the originally tested packaging; and if a single inner packaging was used in the original test, the thicknesses of cushioning between inner packagings shall not be less than the thickness of cushioning between the outside of the packaging and the inner packaging in the original test. If either fewer or smaller inner packagings are used (as compared to the inner packagings used in the drop test), sufficient additional cushioning material shall be used to take up void spaces; (d) The outer packaging shall have passed successfully the stacking test in 6.1.5.6 while empty. The total mass of identical packages shall be based on the combined mass of inner packagings used for the drop test in (a) above; (e) Inner packagings containing liquids shall be completely surrounded with a sufficient quantity of absorbent material to absorb the entire liquid contents of the inner packagings; (f) If the outer packaging is intended to contain inner packagings for liquids and is not leakproof, or is intended to contain inner packagings for solids and is not siftproof, a means of containing any liquid or solid contents in the event of leakage shall be provided in the form of a leakproof liner, plastics bag or other equally efficient means of containment. For packagings containing liquids, the absorbent material required in above shall be placed inside the means of containing the liquid contents; (g) Packagings shall be marked in accordance with 6.1.3 as having been tested to packing group I performance for combination packagings. The marked gross mass in kilograms shall be the sum of the mass of the outer packaging plus one half of the mass of the inner packaging(s) as used for the drop test referred to in (a) above. Such a packaging mark shall also contain a letter "V" as described in 6.1.2.4. 6.1.5.1.8. The competent authority may at any time require proof, by tests in accordance with this section, that serially-produced packagings meet the requirements of the design type tests. For verification purposes records of such tests shall be maintained. 6.1.5.1.9. If an inner treatment or coating is required for safety reasons, it shall retain its protective properties even after the tests. 6.1.5.1.10. Provided the validity of the test results is not affected and with the approval of the competent authority, several tests may be made on one sample. 6.1.5.1.11. Salvage packagings Salvage packagings (see 1.2.1) shall be tested and marked in accordance with the requirements applicable to packing group II packagings intended for the carriage of solids or inner packagings, except as follows: (a) The test substance used in performing the tests shall be water, and the packagings shall be filled to not less than 98 % of their maximum capacity. It is permissible to use additives, such as bags of lead shot, to achieve the requisite total package mass so long as they are placed so that the test results are not affected. Alternatively, in performing the drop test, the drop height may be varied in accordance with 6.1.5.3.4(b); (b) Packagings shall, in addition, have been successfully subjected to the leakproofness test at 30 kPa, with the results of this test reflected in the test report required by 6.1.5.9; (c) Packagings shall be marked with the letter "T" as described in 6.1.2.4. 6.1.5.2. Preparation of packagings for testing 6.1.5.2.1. Tests shall be carried out on packagings prepared as for carriage including, with respect to combination packagings, the inner packagings used. Inner or single receptacles or packagings shall be filled to not less than 98 % of their maximum capacity for liquids or 95 % for solids. For combination packagings where the inner packaging is designed to carry liquids and solids, separate testing is required for both liquid and solid contents. The substances or articles to be carried in the packagings may be replaced by other substances or articles except where this would invalidate the results of the tests. For solids, when another substance is used it shall have the same physical characteristics (mass, grain size, etc.) as the substance to be carried. It is permissible to use additives, such as bags of lead shot, to achieve the requisite total package mass, so long as they are placed so that the test results are not affected. 6.1.5.2.2. In the drop tests for liquids, when another substance is used, it shall be of similar relative density and viscosity to those of the substance being carried. Water may also be used for the liquid drop test under the conditions in 6.1.5.3.4. 6.1.5.2.3. Paper or fibreboard packagings shall be conditioned for at least 24 hours in an atmosphere having a controlled temperature and relative humidity (r.h.). There are three options, one of which shall be chosen. The preferred atmosphere is 23 ± 2 °C and 50 % ± 2 % r.h. The two other options are 20 ± 2 °C and 65 % ± 2 % r.h. or 27 ± 2 °C and 65 % ± 2 % r.h. NOTE: Average values shall fall within these limits. Short-term fluctuations and measurement limitations may cause individual measurements to vary by up to ±5 % relative humidity without significant impairment of test reproducibility. 6.1.5.2.4. Bung-type barrels made of natural wood shall be left filled with water for at least 24 hours before the tests. 6.1.5.2.5. To check that their chemical compatibility with the liquids is sufficient, plastics drums and jerricans in accordance with 6.1.4.8 and if necessary composite packagings (plastics material) in accordance with 6.1.4.19 shall be subjected to storage at ambient temperature for six months, during which time the test samples shall be kept filled with the goods they are intended to carry. For the first and last 24 hours of storage, the test samples shall be placed with the closure downwards. However, packagings fitted with a vent shall be so placed on each occasion for five minutes only. After this storage the test samples shall undergo the tests prescribedin 6.1.5.3 to 6.1.5.6. When it is known that the strength properties of the plastics material of the inner receptacles of composite packagings (plastics material) are not significantly altered by the action of the filling substance, it shall not be necessary to check that the chemical compatibility is sufficient. A significant alteration in strength properties means: (a) distinct embrittlement; or (b) a considerable decrease in elasticity, unless related to a not less than proportionate increase in the elongation under load. Where the behaviour of the plastics material has been established by other means, the above compatibility test may be dispensed with.

NOTE: For plastics drums and jerricans and composite packagings (plastics material) made of high or average molecular mass polyethylene, see also 6.1.5.2.6 below. 6.1.5.2.6. For high molecular mass polyethylene drums and jerricans in accordance with 6.1.4.8 and if necessary composite packagings of high molecular mass polyethylene in accordance with 6.1.4.19, conforming to the following specifications: - relative density at 23 °C after thermal conditioning for one hour at 100 °C >= 0,940, in accordance with ISO Standard 1183, - melt flow rate at 190 °C/21,6 kg load <= 12 g/10 min, in accordance with ISO Standard 1133, for jerricans in accordance with 6.1.4.8 of packing groups II and III and, if necessary, for composite packagings in accordance with 6.1.4.19 in average molecular mass polyethylene meeting the following specifications: - relative density at 23 °C after thermal conditioning for one hour at 100 °C >= 0,940, in accordance with ISO Standard 1183, - melt flow rate at 190 °C/2,160 kg load <= 0,5 g/10 min and >= 0,1g/10 min, in accordance with ISO Standard 1133, - melt flow rate at 190 °C/5 kg load <= 3 g/10 min and >= 0,5 g/10 min, in accordance with ISO Standard 1133, chemical compatibility with the liquids listed in 6.1.6.2 may be verified as follows with standard liquids (see 6.1.6.1). The sufficient chemical compatibility of these packagings may be verified by storage for three weeks at 40 °C with the appropriate standard liquid; where this standard liquid is water, proof of chemical compatibility is not required. For the first and last 24 hours of storage, the test samples shall be placed with the closure downwards. However, packagings fitted with a vent shall be so placed on each occasion for five minutes only. After this storage, the test samples shall undergo the tests prescribed in 6.1.5.3 to 6.1.5.6. When a packaging design-type has satisfied the approval tests with a standard liquid, the comparable filling substances listed in 6.1.6.2 may be accepted for carriage without further testing, subject to the following conditions: - the relative densities of the filling substances shall not exceed that used to determine the height for the drop test and the mass for the stacking test; - the vapour pressures of the filling substances at 50 °C or 55 °C shall not exceed that used to determine the pressure for the internal pressure test.

For drums and jerricans conforming to 6.1.4.8, and where necessary composite packagings conforming to 6.1.4.19, made of high or average molecular mass polyethylene, which have passed the test in 6.1.5.2.6, filling substances other than those listed in 6.1.6.2 may also be approved. Such approval shall be based on laboratory tests proving that the effect of such filling substances on the test specimens is less than that of the standard liquids. The processes of deterioration to be taken into account shall be the following: softening through swelling, cracking under stress and molecular degradation. The same conditions as those set out in 6.1.5.2.6 above shall apply with respect to relative density and vapour pressure. 6.1.5.2.8.

For outer packagings, the headings in the table relate to fibreboard or similar materials whose performance may be rapidly affected by moisture; plastics which may embrittle at low temperature; and other materials such as metal whose performance is not affected by moisture or temperature. If a primary receptacle and a secondary packaging, which together form an inner packaging, are made of different materials, the material of the primary receptacle determines the appropriate test. In instances where a primary receptacle is made of two materials, the material most liable to damage shall determine the appropriate tests. 6.3.2.5. (a) Samples shall be subjected to free-fall drops on to a rigid, non-resilient, flat, horizontal surface from a height of 9 m.

One sample shall be dropped in a vertical free fall from a height of 1 m, measured from the top of the steel rod. A second sample shall be dropped from the same height in an orientation perpendicular to that used for the first. In each instance, the packaging shall be so orientated that the steel rod could penetrate the primary receptacle(s). Following each impact, there shall be no leakage from the primary receptacle(s). 6.3.2.7. The competent authority may permit the selective testing of packagings that differ only in minor respects from a tested type, e.g. smaller sizes of inner packagings or inner packagings of lower net mass; and packagings such as drums, bags and boxes which are produced with small reductions in external dimension(s). 6.3.2.8. Provided an equivalent level of performance is maintained, the following variations in the primary receptacles placed within a secondary packaging are allowed without the need for further testing of the completed packaging: (a) Primary receptacles of equivalent or smaller size as compared to the tested primary receptacles may be used provided: (i) the primary receptacles are of similar design to the primary receptacle tested (e.g. shape: round, rectangular, etc.); (ii) the material of construction of the primary receptacle (e.g. glass, plastics, metal etc.) offers resistance to impact and stacking forces equivalent to or better than that of the primary receptacle originally tested; (iii) the primary receptacles have the same or smaller openings and the closure is of equivalent design (e.g. screw cap, friction lid, etc.); (iv) sufficient additional cushioning material is used to take up empty spaces and to prevent significant movement of the primary receptacles; and (v) primary receptacles are oriented within the secondary packagings in the same manner as in the tested package. (b) A lesser number of the tested primary receptacles, or of the alternative types of primary receptacles identified in (a) above, may be used provided sufficient cushioning is added to fill the void space(s) and to prevent significant movement of the primary receptacles. 6.3.2.9. Inner receptacles of any type may be assembled within an intermediate (secondary) packaging and carried without testing in the outer packaging under the following conditions: (a) The intermediate/outer packaging combination shall have been successfully tested in accordance with 6.3.2.5(a) with fragile (e.g. glass) inner receptacles; (b) The total combined gross mass of inner receptacles shall not exceed one half the gross mass of inner receptacles used for the drop test in (a) above; (c) The thickness of cushioning between inner receptacles and between inner receptacles and the outside of the intermediate packaging shall not be reduced below the corresponding thicknesses in the originally tested packaging; and if a single inner receptacle was used in the original test, the thickness of cushioning between inner receptacles shall not be less than the thickness of cushioning between the outside of the intermediate packaging and the inner receptacle in the original test. When either fewer or smaller inner receptacles are used (as compared to the inner receptacles used in the drop test), sufficient additional cushioning material shall be used to take up the void; (d) The outer packaging shall have successfully passed the stacking test in 6.1.5.6 while empty. The total mass of identical packages shall be based on the combined mass of inner receptacles used in the drop test in (a) above; (e) For inner receptacles containing liquids, an adequate quantity of absorbent material to absorb the entire liquid content of the inner receptacles shall be present; (f) If the outer packaging is intended to contain inner receptacles for liquids and is not leakproof, or is intended to contain inner receptacles for solids and is not siftproof, a means of containing any liquid or solid contents in the event of leakage shall be provided in the form of a leakproof liner, plastics bag or other equally effective means of containment.

Where multilateral approval is effected by issue of certificates by successive countries, each certificate shall bear the appropriate identification mark and the package whose design was so approved shall bear all appropriate identification marks. For example: A/132/B(M)F-96 CH/28/B(M)F-96 would be the identification mark of a package which was originally approved by Austria and was subsequently approved, by separate certificate, by Switzerland. Additional identification marks would be tabulated in a similar manner on the package; (c) The revision of a certificate shall be indicated by a parenthetical expression following the identification mark on the certificate. For example, A/132/B(M)F-96(Rev. 2) would indicate revision 2 of the Austrian package design approval certificate; or A/132/B(M)F-96(Rev. 0) would indicate the original issuance of the Austrian package design approval certificate. For original issuances, the parenthetical entry is optional and other words such as "original issuance" may also be used in place of "Rev. 0". Certificate revision numbers may only be issued by the country issuing the original approval certificate; (d) Additional symbols (as may be necessitated by national requirements) may be added in brackets to the end of the identification mark; for example, A/132/B(M)F-96(SP503); (e) It is not necessary to alter the identification mark on the packaging each time that a revision to the design certificate is made. Such re-marking shall be required only in those cases where the revision to the package design certificate involves a change in the letter type codes for the package design following the second stroke. 6.4.23.11.

The permanent elongation at fracture shall be measured on test specimens of rectangular cross sections in accordance with ISO 6892:1998 using a 50 mm gauge length. 6.7.3.4. Minimum shell thickness 6.7.3.4.1. The minimum shell thickness shall be the greater thickness based on: (a) The minimum thickness determined in accordance with the requirements in 6.7.3.4; and (b) The minimum thickness determined in accordance with the recognized pressure vessel code including the requirements in 6.7.3.3. 6.7.3.4.2. The cylindrical portions, ends (heads) and manhole covers of shells of not more than 1,80 m in diameter shall be not less than 5 mm thick in the reference steel or of equivalent thickness in the steel to be used. Shells of more than 1,80 m in diameter shall be not less than 6 mm thick in the reference steel or of equivalent thickness in the steel to be used. 6.7.3.4.3. The cylindrical portions, ends (heads) and manhole covers of all shells shall be not less than 4 mm thick regardless of the material of construction. 6.7.3.4.4. The equivalent thickness of a steel other than the thickness prescribed for the reference steel in 6.7.3.4.2 shall be determined using the following formula: >PIC FILE= "L_2004121EN.080001.TIF"> where: e1= required equivalent thickness (in mm) of the steel to be used; eo= minimum thickness (in mm) for the reference steel specified in 6.7.3.4.2; Rm1= guaranteed minimum tensile strength (in N/mm2) of the steel to be used (see 6.7.3.3.3); A1= guaranteed minimum elongation at fracture (in %) of the steel to be used according to national or international standards. 6.7.3.4.5.

When a portable tank is fitted with an excess flow valve the excess flow valve shall be so fitted that its seating is inside the shell or inside a welded flange or, when fitted externally, its mountings shall be designed so that in the event of impact its effectiveness shall be maintained. The excess flow valves shall be selected and fitted so as to close automatically when the rated flow specified by the manufacturer is reached. Connections and accessories leading to or from such a valve shall have a capacity for a flow more than the rated flow of the excess flow valve. 6.7.3.5.3. For filling and discharge openings the first shut-off device shall be an internal stop-valve and the second shall be a stop-valve placed in an accessible position on each discharge and filling pipe. 6.7.3.5.4. For filling and discharge bottom openings of portable tanks intended for the carriage of flammable and/or toxic non-refrigerated liquefied gases the internal stop-valve shall be a quick closing safety device which closes automatically in the event of unintended movement of the portable tank during filling or discharge or fire engulfment. Except for portable tanks having a capacity of not more than 1000 litres, it shall be possible to operate this device by remote control. 6.7.3.5.5. In addition to filling, discharge and gas pressure equalizing orifices, shells may have openings in which gauges, thermometers and manometers can be fitted. Connections for such instruments shall be made by suitable welded nozzles or pockets and not be screwed connections through the shell. 6.7.3.5.6. All portable tanks shall be fitted with manholes or other inspection openings of suitable size to allow for internal inspection and adequate access for maintenance and repair of the interior. 6.7.3.5.7. External fittings shall be grouped together so far as reasonably practicable. 6.7.3.5.8. Each connection on a portable tank shall be clearly marked to indicate its function. 6.7.3.5.9. Each stop-valve or other means of closure shall be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperatures expected during transport.

Portable tanks for non-refrigerated liquefied gases shall be provided with one or more spring-loaded pressure-relief devices. The pressure-relief devices shall open automatically at a pressure not less than the MAWP and be fully open at a pressure equal to 110 % of the MAWP. These devices shall, after discharge, close at a pressure not lower than 10 % below the pressure at which discharge starts and shall remain closed at all lower pressures. The pressure-relief devices shall be of a type that will resist dynamic forces including liquid surge. Frangible discs not in series with a spring-loaded pressure-relief device are not permitted. 6.7.3.7.2. Pressure-relief devices shall be designed to prevent the entry of foreign matter, the leakage of gas and the development of any dangerous excess pressure. 6.7.3.7.3. Portable tanks intended for the carriage of certain non-refrigerated liquefied gases identified in portable tank instruction T50 in 4.2.4.2.6 shall have a pressure-relief device approved by the competent authority. Unless a portable tank in dedicated service is fitted with an approved relief device constructed of materials compatible with the load, such device shall comprise a frangible disc preceding a spring-loaded device. The space between the frangible disc and the device shall be provided with a pressure gauge or a suitable telltale indicator. This arrangement permits the detection of disc rupture, pinholing or leakage which could cause a malfunction of the pressure-relief device. The frangible discs shall rupture at a nominal pressure 10 % above the start-to-discharge pressure of the relief device. 6.7.3.7.4. In the case of multi-purpose portable tanks, the pressure-relief devices shall open at a pressure indicated in 6.7.3.7.1 for the gas having the highest maximum allowable pressure of the gases allowed to be carried in the portable tank. 6.7.3.8. Capacity of relief devices 6.7.3.8.1. The combined delivery capacity of the relief devices shall be sufficient that, in the event of total fire engulfment, the pressure (including accumulation) inside the shell does not exceed 120 % of the MAWP. Spring-loaded relief devices shall be used to achieve the full relief capacity prescribed. In the case of multi-purpose tanks, the combined delivery capacity of the pressure-relief devices shall be taken for the gas which requires the highest delivery capacity of the gases allowed to be carried in the portable tank. 6.7.3.8.1.1. To determine the total required capacity of the relief devices, which shall be regarded as being the sum of the individual capacities of the several devices, the following formula(78) shall be used: >PIC FILE= "L_2004121EN.080201.TIF"> where: Q= minimum required rate of discharge in cubic metres of air per second (m3/s) at standard conditions: 1 bar and 0 °C (273 K); F= is a coefficient with the following value: for uninsulated shells F = 1 for insulated shells F = U(649 - t)/13,6 but in no case is less than 0,25 where: U= thermal conductance of the insulation, in kW·m-2·K-1, at 38 °C; t= actual temperature of the non-refrigerated liquefied gas during filling (°C); when this temperature is unknown, let t = 15 °C; The value of F given above for insulated shells may be taken provided that the insulation is in conformity with 6.7.3.8.1.2; A= total external surface area of shell in square metres; Z= the gas compressibility factor in the accumulating condition (when this factor is unknown, let Z equal 1,0); T= absolute temperature in Kelvin (°C + 273) above the pressure-relief devices in the accumulating condition; L= the latent heat of vaporization of the liquid, in kJ/kg, in the accumulating condition; M= molecular mass of the discharged gas; C= a constant which may be taken from the following table which is derived from the following equation as a function of the ratio k of specific heats >PIC FILE= "L_2004121EN.080202.TIF"> where: cp is the specific heat at constant pressure; cv is the specific heat at constant volume. when k > 1: >PIC FILE= "L_2004121EN.080301.TIF"> when k = 1 or k is unknown: >PIC FILE= "L_2004121EN.080302.TIF"> where e is the mathematical constant 2,7183 >TABLE> 6.7.3.8.1.2.

The rated flow capacity marked on the pressure-relief devices shall be determined according to ISO 4126-1:1991. 6.7.3.10. Connections to pressure-relief devices 6.7.3.10.1. Connections to pressure-relief devices shall be of sufficient size to enable the required discharge to pass unrestricted to the safety device. No stop-valve shall be installed between the shell and the pressure-relief devices except when duplicate devices are provided for maintenance or other reasons and the stop-valves serving the devices actually in use are locked open or the stop-valves are interlocked so that at least one of the duplicate devices is always operable and capable of meeting the requirements of 6.7.3.8. There shall be no obstruction in an opening leading to a vent or pressure-relief device which might restrict or cut-off the flow from the shell to that device. Vents from the pressure-relief devices, when used, shall deliver the relieved vapour or liquid to the atmosphere in conditions of minimum back-pressure on the relieving device. 6.7.3.11.

Design approval 6.7.3.14.1. The competent authority or its authorized body shall issue a design approval certificate for any new design of a portable tank. This certificate shall attest that the portable tank has been surveyed by that authority, is suitable for its intended purpose and meets the requirements of this Chapter and where appropriate the provisions for gases provided in portable tank instruction T50 in 4.2.4.2.6. When a series of portable tanks are manufactured without change in the design, the certificate shall be valid for the entire series. The certificate shall refer to the prototype test report, the gases allowed to be carried, the materials of construction of the shell and an approval number. The approval number shall consist of the distinguishing sign or mark of the State in whose territory the approval was granted, i.e. the distinguishing sign for use in international traffic, as prescribed by the Convention on Road Traffic, Vienna 1968, and a registration number. Any alternative arrangements according to 6.7.1.2 shall be indicated on the certificate. A design approval may serve for the approval of smaller portable tanks made of materials of the same kind and thickness, by the same fabrication techniques and with identical supports, equivalent closures and other appurtenances. 6.7.3.14.2. The prototype test report for the design approval shall include at least the following: (a) The results of the applicable framework test specified in ISO 1496-3:1995; (b) The results of the initial test in 6.7.3.15.3; and (c) The results of the impact test in 6.7.3.15.1, when applicable. 6.7.3.15.

For portable tanks intended for the carriage of a single non-refrigerated liquefied gas, the 2,5 year internal examination may be waived or substituted by other test methods specified by the competent authority or its authorized body. 6.7.3.15.6. A portable tank may not be filled and offered for transport after the date of expiry of the last 5 year or 2,5 year periodic test as required by 6.7.3.15.2. However a portable tank filled prior to the date of expiry of the last periodic test may be carried for a period not to exceed three months beyond the date of expiry of the last periodic test. In addition, a portable tank may be carried after the date of expiry of the last periodic test: (a) After emptying but before cleaning, for purposes of performing the next test or inspection required prior to refilling; and (b) Unless otherwise approved by the competent authority, for a period not to exceed six months beyond the date of expiry of the last periodic test, in order to allow the return of dangerous goods for proper disposal or recycling. Reference to this exemption shall be mentioned in the consignment note. 6.7.3.15.7. The exceptional test is necessary when the portable tank shows evidence of damaged or corroded areas, or leakage, or other conditions that indicate a deficiency that could affect the integrity of the portable tank. The extent of the exceptional test shall depend on the amount of damage or deterioration of the portable tank. It shall include at least the 2,5 year test according to 6.7.3.15.5. 6.7.3.15.8. The internal and external examinations shall ensure that: (a) The shell is inspected for pitting, corrosion, or abrasions, dents, distortions, defects in welds or any other conditions, including leakage, that might render the portable tank unsafe for transport; (b) The piping, valves, and gaskets are inspected for corroded areas, defects, and other conditions, including leakage, that might render the portable tank unsafe for filling, discharge or transport; (c) Devices for tightening manhole covers are operative and there is no leakage at manhole covers or gaskets; (d) Missing or loose bolts or nuts on any flanged connection or blank flange are replaced or tightened; (e) All emergency devices and valves are free from corrosion, distortion and any damage or defect that could prevent their normal operation.

When the pressure test is a part of the test, the test pressure shall be the one indicated on the data plate of the portable tank. While under pressure, the portable tank shall be inspected for any leaks in the shell, piping or equipment. 6.7.3.15.10. In all cases when cutting, burning or welding operations on the shell have been effected, that work shall be to the approval of the competent authority or its authorized body taking into account the pressure vessel code used for the construction of the shell. A pressure test to the original test pressure shall be performed after the work is completed. 6.7.3.15.11. When evidence of any unsafe condition is discovered, the portable tank shall not be returned to service until it has been corrected and the pressure test is repeated and passed. 6.7.3.16.

The reference holding time shall be determined by a method recognized by the competent authority on the basis of the following: (a) The effectiveness of the insulation system, determined in accordance with 6.7.4.2.8.2; (b) The lowest set pressure of the pressure limiting device(s); (c) The initial filling conditions; (d) An assumed ambient temperature of 30 °C; (e) The physical properties of the individual refrigerated liquefied gas intended to be carried. 6.7.4.2.8.2. The effectiveness of the insulation system (heat influx in watts) shall be determined by type testing the portable tank in accordance with a procedure recognized by the competent authority. This test shall consist of either: (a) A constant pressure test (for example at atmospheric pressure) when the loss of refrigerated liquefied gas is measured over a period of time; or (b) A closed system test when the rise in pressure in the shell is measured over a period of time. When performing the constant pressure test, variations in atmospheric pressure shall be taken into account. When performing either tests corrections shall be made for any variation of the ambient temperature from the assumed ambient temperature reference value of 30 °C. NOTE: For the determination of the actual holding time before each journey, refer to 4.2.3.7. 6.7.4.2.9. The jacket of a vacuum-insulated double-wall tank shall have either an external design pressure not less than 100 kPa (1 bar) gauge pressure calculated in accordance with a recognized technical code or a calculated critical collapsing pressure of not less than 200 kPa (2 bar) gauge pressure.

Shells, their service and structural equipment shall be designed to withstand without loss of contents (other than quantities of gas escaping through any degassing vents): - static and dynamic stresses in normal conditions of carriage as defined in 6.8.2.1.2 and 6.8.2.1.13; - prescribed minimum stresses as defined in 6.8.2.1.15. 6.8.2.1.2. >TABLE> 6.8.2.1.3. >TABLE> 6.8.2.1.4. Shells shall be designed and constructed in accordance with the requirements of a technical code recognized by the competent authority, in which the material is chosen and the wall thickness determined taking into account maximum and minimum filling and working temperatures, but the following minimum requirements of 6.8.2.1.6 to 6.8.2.1.26 shall be met. 6.8.2.1.5. Tanks intended to contain certain dangerous substances shall be provided with additional protection. This may take the form of additional thickness of the shell (increased calculation pressure) determined in the light of the dangers inherent in the substances concerned or of a protective device (see the special provisions of 6.8.4). 6.8.2.1.6. Welds shall be skilfully made and shall afford the fullest safety. The execution and checking of welds shall comply with the requirements of 6.8.2.1.23. 6.8.2.1.7. Measures shall be taken to protect shells against the risk of deformation as a result of a negative internal pressure. Materials for shells 6.8.2.1.8.

Thermoplastic liners shall consist of thermoplastic sheet material as referred to in 6.9.2.3.4, welded together in the required shape, to which the structural layers are bonded. Durable bonding between liners and the structural layer shall be achieved by the use of an appropriate adhesive. NOTE: For the carriage of flammable liquids the internal layer may require additional measures in accordance with 6.9.2.14, in order to prevent the accumulation of electrical charges. 6.9.2.2.4. The structural layer of the shell is the zone specially designed according to 6.9.2.4 to 6.9.2.6 to withstand the mechanical stresses. This part normally consists of several fibre reinforced layers in determined orientations. 6.9.2.2.5. The external layer is the part of the shell which is directly exposed to the atmosphere.

This layer shall have a mass content in glass of less than 30 % and shall be capable of withstanding exterior conditions, in particular the occasional contact with the substance to be carried. The resin shall contain fillers or additives to provide protection against deterioration of the structural layer of the shell by ultra-violet radiation. 6.9.2.3. Raw materials 6.9.2.3.1. All materials used for the manufacture of FRP tank-containers shall be of known origin and specifications. 6.9.2.3.2. Resins The processing of the resin mixture shall be carried out in strict compliance with the recommendations of the supplier. This concerns mainly the use of hardeners, initiators and accelerators.

Thermoplastic liner material Thermoplastic liners, such as unplastified polyvinyl chloride (PVC-U), polypropylene (PP), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), etc. may be used as lining materials. 6.9.2.3.5. Additives Additives necessary for the treatment of the resin, such as catalysts, accelerators, hardeners and thixotropic substances as well as materials used to improve the tank, such as fillers, colours, pigments etc. shall not cause weakening of the material, taking into account lifetime and temperature expectancy of the design. 6.9.2.4. Shells, their attachments and their service and structural equipment shall be designed to withstand without loss of contents (other than quantities of gas escaping through any degassing vents) during the design lifetime: - the static and dynamic loads in normal conditions of carriage; - the prescribed minimum loads as defined in 6.9.2.5 to 6.9.2.10. 6.9.2.5.

For tanks intended for the carriage of substances which require an increased safety level, i.e. if the tanks are referred to in column (12) of Table A of Chapter 3.2 by a tank code including, the number "4" in its second part (see 4.3.4.1.1), the value of S shall be multiplied by a factor of two, unless the shell is provided with protection against damage consisting of a complete metal skeleton including longitudinal and transverse structural members; K0= a factor related to the deterioration in the material properties due to creep and ageing and as a result of the chemical action of the substances to be carried. It shall be determined by the formula: >PIC FILE= "L_2004121EN.084702.TIF"> where "α" is the creep factor and "β" is the ageing factor determined in accordance with EN 978:1997 after performance of the test according to EN 977:1997. Alternatively, a conservative value of K0 = 2 may be applied. In order to determine α and β the initial deflection shall correspond to 2σ; K1= a factor related to the service temperature and the thermal properties of the resin, determined by the following equation, with a minimum value of 1: K1 = 1,25 - 0,0125 (HDT - 70) where HDT is the heat distortion temperature of the resin, in °C; K2= a factor related to the fatigue of the material; the value of K2 = 1,75 shall be used unless otherwise agreed with the competent authority. For the dynamic design as outlined in 6.9.2.6 the value of K2 = 1,1 shall be used; K3= a factor related to curing and has the following values: - 1,1 where curing is carried out in accordance with an approved and documented process - 1,5 in other cases. 6.9.2.6. At the dynamic stresses, as indicated in 6.8.2.1.2 the design stress shall not exceed the value specified in 6.9.2.5, divided by the factor α. 6.9.2.7. At any of the stresses as defined in 6.9.2.5 and 6.9.2.6, the resulting elongation in any direction shall not exceed 0.2 % or one tenth of the elongation at fracture of the resin, whichever is lower. 6.9.2.8. At the specified test pressure, which shall not be less than the relevant calculation pressure as specified in 6.8.2.1.14 (a) and (b) the maximum strain in the shell shall not be greater than the elongation at fracture of the resin. 6.9.2.9.

COUNCIL DIRECTIVE 96/49/EC of 23 July 1996 on the approximation of the laws of the Member States with regard to the transport of dangerous goods by rail

THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 75 thereof,

Having regard to the proposal from the Commission (1),

Having regard to the opinion of the Economic and Social Committee (2),

Acting in accordance with the procedure referred to in Article 189c of the Treaty (3),

(1) Whereas in recent years the transport of dangerous goods by rail has considerably expanded, thus increasing the risks of accidents occurring; whereas measures must therefore be taken to ensure that such transport is carried out under the best possible conditions of safety;

(2) Whereas all Member States are Contracting Parties to the Convention concerning international carriage by rail (COTIF), which, in Appendix B thereto, defines uniform rules concerning the contract for international carriage of goods by rail (CIM), Annex 1 to which constitutes the regulations concerning the international carriage of dangerous goods by rail (RID); whereas the geographical scope of the Convention extends beyond the Community;

(3) Whereas the Convention does not cover the national carriage of dangerous goods by rail; whereas it is therefore important to ensure the uniform application of harmonized safety rules throughout the Community; whereas the most appropriate way of achieving this is to align the laws applied by the Member States on the RID;

(4) Whereas, in compliance with the principle of subsidiarity, these laws must be approximated in order to ensure a high level of safety for national and international transport operations, to guarantee the elimination of distortions of competition by facilitating the free movement of goods and services throughout the Community and to ensure consistency with the other Community provisions;

(5) Whereas the provisions of this Directive are without prejudice to the commitment entered into by the Community and its Member States, in accordance with the goals set under Agenda 21, Chapter 19, at the UNCED Conference in June 1992 in Rio de Janeiro, to strive for the future harmonization of systems for the classification of dangerous substances;

(6) Whereas no specific Community legislation yet governs the safety conditions under which biological agents and genetically modified micro-organisms, regulated under Directives 90/219/EEC (4), 90/220/EEC (5) and 90/676/EEDC (6) should be transported;

(7) Whereas the provisions of this Directive are without prejudice to the application of other Community provisions in the field of worker safety and environmental protection;

(8) Whereas the Member States must be able to apply specific traffic regulations to the transport on their territory of dangerous goods by rail;

(9) Whereas, the Member States should retain the right, with regard to the transport of dangerous goods by rail, provisionally to implement rules in conformity with the United Nations recommendations on the multimodal transport of dangerous goods, in so far as the RID is not yet harmonized with those regulations, which should facilitate the inter-modal transport of dangerous goods;

(10) Whereas each Member State must retain the right to regulate or prohibit, strictly for reasons other than safety, the internal transport of certain dangerous goods by rail;

(11) Whereas account should be taken of the more stringent safety measures applied in the Channel Tunnel because of its specific characteristics, in particular its route and length; whereas provision should also be made for Member States to be able to introduce the same kind of measures where similar situations arise; whereas it must be possible for some Member States to apply more stringent standards for material intended for transport because of the ambient temperature in their countries;

(12) Whereas, in view of the volume of investment required in this sector, a transitional period should be laid down to enable Member States to retain temporarily certain specific national provisions concerning construction requirements or the use of tanks, receptacles, packaging or an emergency action code;

(13) Whereas the introduction of new developments in technology and industry must not be hindered; whereas temporary derogations should be provided for that purpose;

(14) Whereas the provisions of the RID authorize the conclusion of agreements derogating therefrom; whereas the large number of agreements concluded bilaterally between Member States impedes the free provision of dangerous-goods transport services; whereas including the necessary provisions in the Annex to this Directive should overcome the need for such derogations; whereas provision should be made for a transitional period during which the Member States may continue to apply existing agreements amongst themselves;

(15) Whereas the transport of dangerous goods by rail to or from a third country is authorized, provided it is carried out in accordance with the requirements of the RID; whereas, however, in the case of transport operations from and to the Republics of the former Soviet Union which are not contracting parties to the COTIF, the Member States are entitled to adopt appropriate measures with regard to such operations; whereas they guarantee a level of safety equivalent to that provided for in the RID;

(16) Whereas it must be possible to adapt this Directive rapidly to technical progress, notably by adoption of the new provisions laid down within the framework of the RID; whereas, for that purpose, a Committee should be set up and a procedure established for close cooperation between Member States and the Commission within that Committee,

HAS ADOPTED THIS DIRECTIVE:

CHAPTER I Scope

1. This Directive shall apply to the transport of dangerous goods by rail within Member States or between Member States. Member States may, however, exempt from the scope of this Directive the transport of dangerous goods conducted by means of transport equipment belonging to or under the responsibility of the armed forces.

2. This Directive shall not, however, affect the Member State's right, having due regard to Community law, to lay down specific safety requirements for the national or international transport of dangerous goods by rail, in so far as the Annex thereto does not cover that area, in particular as regards, inter alia:

- the running of trains;

- the marshalling of freight wagons in trains in national traffic;

- operating rules for operations ancillary to transport such as marshalling and stabling;

- the training of staff and the management of information concerning the dangerous goods transported;

- special rules for the transport of dangerous goods in passenger trains.

For the purposes of this Directive:

- 'RID` shall mean the regulations concerning the international carriage of dangerous goods by rail, appearing as Annex I to Appendix B to the Convention concerning international carriage by rail (COTIF), together with its amendments;

- 'CIM` shall mean the uniform rules concerning the contract for international carriage of goods by rail, appearing as Appendix B to the Convention concerning international carriage by rail (COTIF), together with its amendments;

- 'dangerous goods` shall mean those substances and articles the transport by rail of which is prohibited or authorized only on certain conditions by the Annex to this Directive;

- 'transport` shall mean any operation for the transport of dangerous goods by rail, conducted wholly or partially within the territory of a Member State, including the activities of loading, unloading and transfer to or from another mode of transport and the stops necessitated by the circumstances of the transport, covered by the Annex to this Directive, without prejudice to the arrangements laid down by the laws of the Member States concerning liability in respect of such operations; it shall not include transport wholly performed within the perimeter of an undertaking.

1. Without prejudice to Article 6, dangerous goods the transport of which is prohibited by the provisions of the Annex may not be transported by rail.

2. Save as otherwise provided in this Directive and without prejudice to the rules on market access for railway undertakings or to the rules generally applicable to the transport of goods by rail, the transport of dangerous goods by rail shall be authorized, subject to compliance with the rules laid down in the Annex.

CHAPTER II Derogations, restrictions and exemptions

Each Member State may, for the purposes of national rail transport operations within its territory, retain provisions of its national law on the transport of dangerous goods by rail which are consistent with the United Nations recommendations on the transport of dangerous goods, until such time as the Annex to this Directive is revised to reflect those recommendations. In such cases, the Member State concerned shall inform the Commission thereof.

Article 5

1. Without prejudice to other Community provisions, each Member State shall retain the right to regulate or prohibit, strictly for reasons other than safety during transport connected in particular with national security or environmental protection, the transport of certain dangerous goods within its territory.

2. (a) For transport via the Channel Tunnel, France and the United Kingdom may impose more stringent provisions than those provided for in the Annex. The Commission shall be informed of such provisions and it shall inform the other Member States.

(b) Where a Member State considers that stricter provisions should be applied to transport through tunnels with characteristics similar to the Channel Tunnel within its territory, it shall inform the Commission. The Commission, acting in accordance with the procedure laid down in Article 9, shall decide whether the tunnel in question has similar characteristics. Provisions adopted by a Member State shall be notified to the Commission, which shall inform the other Member States.

(c) A Member State in which the ambient temperature is regularly lower than - 20 °C may impose more stringent standards as regards the operating temperature of material intended for use in the national transport of dangerous goods by rail within its territory until provisions on the appropriate reference temperatures for given climatic zones are incorporated in the Annex.

3. If, on the occasion of an accident or an incident, a Member State considers that the safety provisions applicable have been found to be insufficient to limit the hazards involved in the transport operation and if there is an urgent need to take action, that Member State shall notify the Commission at the planning stage of the measures which it proposes to take. Acting in accordance with the procedure laid down in Article 9, the Commission shall decide whether the implementation of the measures in question should be authorized and shall determine the duration thereof.

4. Member States may maintain all national provisions applicable on 31 December 1996 to the transport and packaging of substances containing dioxins or furans.

1. Each Member State may authorize the transport by rail within its territory of dangerous goods classified, packed and labelled in accordance with international requirements for maritime or air transport whenever the transport involves a sea or air voyage.

Where a national or international journey involves carriage by sea, a Member State may apply provisions additional to those of the Annex to take account of international rules governing maritime transport, including international rules governing ferry transport.

2. The provisions of the Annex concerning the format of transport documentation and the use of languages in marking or in the documentation required shall not apply to transport operations confined to the territory of a single Member State. A Member State may authorize the use of documentation and languages other than those provided for in the Annex for transport operations confined to its territory.

3. Within its territory a Member State may allow the use of rail wagons constructed before 1 January 1997 which do not conform with the provisions of this Directive, but were constructed according to national provisions in force on 31 December 1996, provided that those wagons are maintained to the required safety levels.

4. A Member State may retain national provisions in force on 31 December 1996 relating to the construction, use and conditions of carriage of new tanks, and new receptacles as defined in Class 2 of the Annex, which differ from the provisions of that Annex, until references to standards for the construction and use of tanks and receptacles are added to the Annex, with the same binding force as the provisions therein, but in any event no later than 31 December 1998. Receptacles and tanks constructed before 1 January 1999 and maintained to the required safety levels may continue to be used under the original conditions.

5. A Member State may retain national provisions other than those in the Annex with regard to the reference temperature for the transport in its territory of liquefied gases or mixtures of liquefied gases, until provisions relating to appropriate reference temperatures for designated climatic areas are incorporated into European standards and referred to in the Annex.

6. A Member State may allow the use, in transport within its territory, of packaging constructed but not certified in accordance with the RID before 1 January 1997, provided that such packaging bears the date of its manufacture, is capable of passing the tests laid down in national provisions in force on 31 December 1996 and provided that they are maintained to the relevant safety levels (including testing and inspection where required), according to the following scheme: metal intermediate bulk containers and metal drums exceeding 50 litres in capacity may be used for up to 15 years after the date of their manufacture; other metal packagings and all plastic packagings may be used for up to five years after the date of their manufacture, but not after 31 December 1998.

7. A Member State may authorize the transport within its territory of certain dangerous goods packed before 1 January 1997 until 31 December 1998, provided that the goods are classified, packed and labelled in accordance with the requirements laid down in national provisions in force before 1 January 1997.

8. A Member State may retain the provisions of its national legislation which are in force on 31 December 1996 and relate to the display of an emergency action code in place of the hazard identification number, laid down in the Annex, for national rail transport operations conducted within its territory.

9. Any Member State may, after consulting the Commission, maintain provisions less stringent than those in the Annex for the transport by rail within its territory of small quantities of certain dangerous goods, with the exception of substances having a medium or high level of radioactivity.

10. A Member State may authorize within its territory ad hoc transport operations involving dangerous goods or transport operations which are prohibited by the Annex or transport operations performed under conditions different from those laid down in the Annex.

11. With due regard to Community law, this Directive shall not prejudice the right of a Member State, after consultation with the Commission, to authorize regular transport operations on particular designated routes within its territory, of dangerous goods, forming part of a defined industrial process, which are either prohibited by the Annex or are performed under conditions different from those laid down in the Annex where those operations are of a local nature and are tightly controlled under clearly specified conditions.

12. Provided that there is no loss of safety, a Member State may grant temporary derogations from the Annex for the purpose of carrying out within its territory the trials necessary before the amendment of that Annex in order to adapt them to technological and industrial developments. The Commission shall be informed accordingly and shall in turn inform the other Member States.

Those temporary derogations, agreed among the Member States' competent authorities on the basis of the Annex, shall take the form of a multilateral agreement proposed to all the Member States' competent authorities by the authority that takes the initiative on any agreement. The Commission shall be informed.

The derogations referred to in the first and second subparagraphs shall be applied without discrimination on grounds of the nationality or place of establishment of the consignor, operator or consignee; they may last for up to five years and shall be non-renewable.

13. A Member State may, until 31 December 1998 at the latest, apply existing agreements with other Member States, without discrimination on grounds of the nationality or place of establishment of the consignor, operator or consignee. Any future derogations shall comply with paragraph 12.

14. In accordance with Community law, this Directive shall not affect a Member State's right, after consulting the Commission, to authorize the transport of dangerous goods under conditions less stringent than those laid down in the Annex to this Directive in the case of local transport over short distances within the perimeters of ports, airports or industrial sites.

Article 7

1. Subject to national or Community provisions on market access, the transport of dangerous goods by rail between Community territory and third countries shall be authorized in so far as it complies with the requirements of the RID.

2. This Directive shall not affect a Member State's right, after informing the Commission, to adopt regulations for its territory on the transport of dangerous goods by rail from and to those Republics of the former Soviet Union that are not contracting parties to the COTIF. Such regulations shall apply only to the transport of dangerous goods by rail (in packaging, in bulk or in tanks) by means of railway wagons authorized in a State which is not a contracting party to the COTIF. By means of appropriate measures and obligations the Member States concerned shall guarantee the maintenance of a level of safety equivalent to that provided for in the RID. In the case of certain Member States the provisions referred to in this paragraph shall apply only to tank wagons.

CHAPTER III Final provisions

CHAPTER 1.7

General requirements concerning Class 7

1.7.1. General

1.7.1.1. This Directive establishes standards of safety which provide an acceptable level of control of the radiation, criticality and thermal hazards to persons, property and the environment that are associated with the carriage of radioactive material. These standards are based on the IAEA Regulations for the Safe Transport of Radioactive Material (ST-1), IAEA, Vienna (1996). Explanatory material on ST-1 can be found in "Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material (1996 Edition)", Safety Standard Series No ST-2, IAEA, Vienna (to be published).

1.7.1.2. The objective of this Directive is to protect persons, property and the environment from the effects of radiation during the transport of radioactive material. This protection is achieved by requiring:

(a) Containment of the radioactive contents;

(b) Control of external radiation levels;

(c) Prevention of criticality; and

(d) Prevention of damage caused by heat.

These requirements are satisfied firstly by applying a graded approach to contents limits for packages and wagons and to performance standards applied to package designs depending upon the hazard of the radioactive contents. Secondly, they are satisfied by imposing requirements on the design and operation of packages and on the maintenance of packagings, including a consideration of the nature of the radioactive contents. Finally, they are satisfied by requiring administrative controls including, where appropriate, approval by competent authorities.

1.7.1.3. This Directive applies to the transport of radioactive material by rail including transport which is incidental to the use of the radioactive material. Transport comprises all operations and conditions associated with and involved in the movement of radioactive material; these include the design, manufacture, maintenance and repair of packaging, and the preparation, consigning, loading, carriage including in-transit storage, unloading and receipt at the final destination of loads of radioactive material and packages. A graded approach is applied to the performance standards in this Directive that is characterized by three general severity levels:

(a) Routine conditions of transport (incident free);

(b) Normal conditions of transport (minor mishaps);

(c) Accident conditions of transport.

1.7.2. Radiation protection programme

1.7.2.1. The transport of radioactive material shall be subject to a Radiation Protection Programme which shall consist of systematic arrangements aimed at providing adequate consideration of radiation protection measures.

1.7.2.2. The nature and extent of the measures to be employed in the programme shall be related to the magnitude and likelihood of radiation exposures. The programme shall incorporate the requirements in 1.7.2.3, and 1.7.2.4, CV33 (1.1) and (1.4) of 7.5.11 and applicable emergency response procedures. Programme documents shall be available, on request, for inspection by the relevant competent authority.

1.7.2.3. Protection and safety shall be optimised in order that the magnitude of individual doses, the number of persons exposed, and the likelihood of incurring exposure shall be kept as low as reasonably achievable, economic and social factors being taken into account, and doses to persons shall be below the relevant dose limits. A structured and systematic approach shall be adopted and shall include consideration of the interfaces between transport and other activities.

1.7.2.4. For occupational exposures arising from transport activities, where it is assessed that the effective dose:

(a) is most unlikely to exceed 1 mSv in a year, no special work patterns, detailed monitoring, dose assessment programmes or individual record keeping shall be required;

(b) is likely to be between 1 mSv and 6 mSv in a year, a dose assessment programme via work place monitoring or individual monitoring shall be conducted;

(c) is likely to exceed 6 mSv in a year, individual monitoring shall be conducted.

When individual monitoring or work place monitoring is conducted, appropriate records shall be kept.

1.7.3. Quality assurance

Quality assurance programmes based on international, national or other standards acceptable to the competent authority shall be established and implemented for the design, manufacture, testing, documentation, use, maintenance and inspection of all special form radioactive material, low dispersible radioactive material and packages and for transport and in-transit storage operations to ensure compliance with the relevant requirements of this Directive. Certification that the design specification has been fully implemented shall be available to the competent authority. The manufacturer, consignor or user shall be prepared to provide facilities for competent authority inspection during manufacture and use and to demonstrate to any cognizant competent authority that:

(a) the manufacturing methods and materials used are in accordance with the approved design specifications; and

(b) all packagings are periodically inspected and, as necessary, repaired and maintained in good condition so that they continue to comply with all relevant requirements and specifications, even after repeated use.

Where competent authority approval is required, such approval shall take into account and be contingent upon the adequacy of the quality assurance programme.

1.7.4. Special arrangement

1.7.4.1. Special arrangement shall mean those requirements, approved by the competent authority, according to which consignments which do not satisfy all the requirements of this Directive applicable to radioactive material may be carried.

NOTE

Special arrangement is not considered to be a temporary derogation in accordance with 1.5.1.

1.7.4.2. Consignments for which conformity with any requirement applicable to Class 7 is impracticable shall not be carried except under special arrangement. Provided the competent authority is satisfied that conformity with the Class 7 requirements of this Directive is impracticable and that the requisite standards of safety established by this Directive have been demonstrated through alternative means the competent authority may approve special arrangement transport operations for single or a planned series of multiple consignments. The overall level of safety in transport shall be at least equivalent to that which would be provided if all the applicable requirements had been met. For international consignments of this type, multilateral approval shall be required.

1.7.5. Radioactive material possessing other dangerous properties

In addition to the radioactive and fissile properties, any subsidiary risk of the contents of the package, such as explosiveness, flammability, pyrophoricity, chemical toxicity and corrosiveness, shall also be taken into account in the packing, labelling, marking, placarding, stowage, separation and carriage, in order to be in compliance with all the relevant requirements of this Directive.

CHAPTER 1.8

Checks and other support measures to ensure compliance with safety requirements

1.8.1. Administrative controls of dangerous goods

1.8.1.1. The competent authorities of the Member States may, on their national territory, at any time, conduct spot checks to verify whether the requirements concerning the carriage of dangerous goods have been met.

These checks shall, however, be made without endangering persons, property or the environment and without major disruption of rail services.

1.8.1.2. Participants in the carriage of dangerous goods (Chapter 1.4) shall, without delay, in the context of their respective obligations, provide the competent authorities and their agents with the necessary information for carrying out the checks.

1.8.1.3. The competent authorities may also, for the purposes of carrying out checks on the premises of the enterprises participating in the carriage of dangerous goods (Chapter 1.4), make inspections, consult the necessary documents and remove samples of dangerous goods or packagings for examination, provided that safety is not jeopardized thereby. The participants in the carriage of dangerous goods (Chapter 1.4) shall also make the wagons or parts of wagons and the equipment and installations accessible for the purpose of checking where this is possible and reasonable. They may, if they deem necessary, designate a person from the enterprise to accompany the representative of the competent authority.

1.8.1.4. If the competent authorities observe that the requirements of this Directive have not been met, they may prohibit a consignment or interrupt a transport operation until the defects observed are rectified, or they may prescribe other appropriate measures. Immobilization may take place on the spot or at another place selected by the authorities for safety reasons. These measures shall not cause a major disruption in rail services.

1.8.2. Mutual administrative support

1.8.2.1. The Member States shall agree on mutual administrative support for the implementation of this Directive.

1.8.2.2. When a Member State has reasons to observe that the safety of the carriage of dangerous goods on its territory is compromised as a result of very serious or repeated infringements by an enterprise which has its headquarters on the territory of another Member State, it shall notify the competent authorities of this Member State of such infringements. The competent authorities of the Member State on the territory of which the very serious or repeated infringements were observed may request the competent authorities of the Member State on the territory of which the enterprise has its headquarters to take appropriate measures against the offender(s). The transmission of data referring to persons shall not be permitted unless it is necessary for the prosecution of very serious or repeated infringements.

UN No 1325 FLAMMABLE SOLID, ORGANIC, N.O.S.

UN No 1993 FLAMMABLE LIQUID, N.O.S.

The entries defined under B, C and D are defined as collective entries.

2.1.1.3. For packing purposes, certain substances may be assigned to packing groups in accordance with their degree of danger. The packing groups have the following meanings:

Packing group I: Substances presenting high danger

Packing group II: Substances presenting medium danger

Packing group III: Substances presenting low danger

2.1.2. Principles of classification

2.1.2.1. The dangerous goods covered by the heading of a class are defined on the basis of their properties according to sub-section 2.2.x.1 of the relevant class. Assignment of dangerous goods to a class and a packing group is made according to the criteria mentioned in the same sub-section 2.2.x.1. Assignment of one or several subsidiary risk(s) to a dangerous substance or article is made according to the criteria of the class or classes corresponding to those risks, as mentioned in the appropriate sub-section(s) 2.2.x.1.

2.1.2.2. All dangerous goods entries are listed in table A of Chapter 3.2 in the numerical order of their UN Number. This table contains relevant information on the goods listed, such as name, class, packing group(s), label(s) to be affixed, packing and carriage requirements.

NOTE:

An alphabetical list of these entries is given in table B of Chapter 3.2.

2.1.2.3. Dangerous goods which are listed or defined in sub-section 2.2.x.2 of each class are not to be accepted for carriage.

2.1.2.4. Goods not mentioned by name, i.e. goods not listed as single entries in table A of Chapter 3.2 and not listed or defined in one of the above-mentioned sub-sections 2.2.x.2 shall be assigned to the relevant class in accordance with the procedure in 2.1.3. In addition, the subsidiary risk (if any) and the packing group (if any) shall be determined. Once the class, subsidiary risk (if any) and packing group (if any) have been established the relevant UN number shall be determined. The decision trees in sub-sections 2.2.x.3 (list of collective entries) at the end of each class indicate the relevant parameters for selecting the relevant collective entry (UN number). In all cases the most specific collective entry covering the properties of the substance or article shall be selected, according to the hierarchy indicated in 2.1.1.2 by the letters B, C and D respectively. If the substance or article cannot be classified under entries of type B or C according to 2.1.1.2, then, and only then shall it be classified under an entry of type D.

2.1.2.5. On the basis of the test procedures of Chapter 2.3 and the criteria set out in sub-sections 2.2.x.1 of classes when it is so specified, it may be determined that a substance, solution or mixture of a certain class, mentioned by name in Table A of Chapter 3.2, does not meet the criteria of that class. In such a case, the substance, solution or mixture is deemed not to belong to that class.

2.1.2.6. For the purposes of classification, substances with a melting point or initial melting point of 20 °C or lower at a pressure of 101,3 kPa shall be considered to be liquids. A viscous substance for which a specific melting point cannot be determined shall be subjected to the ASTM D 4359-90 test or to the test for determining fluidity (penetrometer test) prescribed in 2.3.4.

2.1.3. Classification of substances, including solutions and mixtures (such as preparations and wastes), not mentioned by name

2.1.3.1. Substances, including solutions and mixtures, not mentioned by name shall be classified according to their degree of danger on the basis of the criteria mentioned in sub-section 2.2.x.1 of the various classes. The danger(s) presented by a substance shall be determined on the basis of its physical and chemical characteristics and physiological properties. Such characteristics and properties shall also be taken into account when such experience leads to a more stringent assignment.

2.1.3.2. A substance not mentioned by name in table A of Chapter 3.2 presenting a single hazard shall be classified in the relevant class under a collective entry listed in sub-section 2.2.x.3 of that class.

2.1.3.3. A solution or mixture containing only one dangerous substance mentioned by name in table A of Chapter 3.2, together with one or more non-dangerous substance(s), shall be regarded as the dangerous substance listed by name, unless:

(a) the solution or mixture is specifically mentioned by name in table A of Chapter 3.2; or

(b) it is quite clear from the entry for the dangerous substance that it is applicable only to the pure or technically pure substance; or

(c) the class, physical state or packing group of the solution or mixture is different from that of the dangerous substance.

In the case of (b) or (c), the solution or mixture shall be classified as a substance mentioned by name in the relevant class under a collective entry according to sub-section 2.2.x.3 of that class, taking account of any subsidiary risks, unless the substance or mixture does not meet the criteria of a particular class and is not therefore subject to the requirements of this Directive.

2.1.3.4. Solutions and mixtures containing one of the following substances mentioned by name shall always be classified under the same entry as the substance they contain, provided they do not have the hazard characteristics as indicated in 2.1.3.5:

- Class 3

UN No 1921 PROPYLENEIMINE, INHIBITED;

unless they contain one of the substances of Class 3 or Class 6.1 or Class 8 listed above; in which case they shall be classified accordingly.

2.1.3.5. Substances not mentioned by name in table A of Chapter 3.2, having more than one hazard characteristic and solutions or mixtures containing several dangerous substances shall be classified under a collective entry (see 2.1.2.4) and packing group of the appropriate class in accordance with their hazard characteristics. Such classification according to the hazard characteristics shall be carried out as follows:

2.1.3.5.1. The physical and chemical characteristics and physiological properties shall be determined by measurement or calculation and the substance, solution or mixture shall be classified according to the criteria mentioned in sub-section 2.2.x.1 of the various classes.

2.1.3.5.2. If this determination is not possible without disproportionate cost or effort (as for some kinds of wastes), the substance, solution or mixture shall be classified in the class of the component presenting the major hazard.

2.1.3.5.3. If the hazard characteristics of the substance, solution or mixture fall within more than one class or group of substances listed below then the substance, solution or mixture shall be classified in the class or group of substances corresponding to the major hazard on the basis of the following order of precedence:

(a) Material of Class 7 (apart from radioactive material in excepted packages where the other hazardous properties take precedence);

(i) Infectious substances of Class 6.2.

2.1.3.5.4. If the hazard characteristics of the substance fall within more than one class or group of substances not listed in 2.1.3.5.3 above, the substance shall be classified in accordance with the same procedure but the relevant class shall be selected according to the precedence of hazards table in 2.1.3.9.

2.1.3.6. The most specific applicable generic entry (see 2.1.2.4) shall always be used, i.e. a general n.o.s. entry shall only be used if a generic entry or a specific n.o.s. entry cannot be used.

2.1.3.7. Solutions and mixtures of oxidizing substances or substances with an oxidizing subsidiary risk may have explosive properties. In such a case they are not to be accepted for carriage unless they meet the requirements for Class 1.

2.1.3.8. For the purposes of this Directive, substances, solutions and mixtures (such as preparations and wastes) which cannot be assigned to Classes 1 to 8 or Class 9 entries other than UN Nos 3077 and 3082, but which may be assigned to UN Nos 3077 or 3082 on the basis of the test methods and criteria of section 2.3.5 shall be considered to be pollutant to the aquatic environment. Solutions and mixtures (such as preparations and wastes) for which no data conforming to the classification criteria are available shall be considered to be pollutant to the aquatic environment if the LC50 (see definitions in 2.3.5.1, 2.3.5.2 and 2.3.5.3) evaluated according to the following formula:

Classification of a mixture

Description of the mixture to be classified:

Mixture consisting of a flammable liquid classified in Class 3, packing group III, a toxic substance in Class 6.1, packing group II and a corrosive substance in Class 8, packing group I.

Procedure:

The intersection of line 3 III with column 6.1 II gives 6.1 II.

The intersection of line 6.1 II with column 8 I LIQ gives 8 I.

This mixture has therefore to be classified in Class 8 under:

UN No 2922 CORROSIVE LIQUID, TOXIC, N.O.S. packing group I.

2. Examples for the classification of mixtures and solutions under a class and a packing group:

A phenol solution of Class 6.1, (II), in benzene of Class 3, (II) is to be classified in Class 3, (II); this solution is to be classified under UN No 1992 FLAMMABLE LIQUID, TOXIC, N.O.S., Class 3, (II), by virtue of the toxicity of the phenol.

A solid mixture of sodium arsenate of Class 6.1, (II) and sodium hydroxide of Class 8, (II) is to be classified under UN No 3290 TOXIC SOLID, CORROSIVE, INORGANIC, N.O.S., in Class 6.1 (II).

2.1.4. Classification of samples

2.1.4.1. When the class of a substance is uncertain and it is being carried for further testing, a provisional class, proper shipping name and UN number shall be assigned on the basis of the consignor's knowledge of the substance and application of:

(a) the classification criteria of Chapter 2.2; and

(b) the requirements of this Chapter.

The most severe packing group possible for the proper shipping name chosen shall be used.

Where this requirement is used the proper shipping name shall be supplemented with the word "sample" (e.g., FLAMMABLE LIQUID, N.O.S., Sample). In certain instances, where a specific proper shipping name is provided for a sample of a substance considered to meet certain classification criteria (e.g., GAS SAMPLE, NON-PRESSURIZED, FLAMMABLE, UN 3167) that proper shipping name shall be used. When an N.O.S. entry is used to carry the sample, the proper shipping name need not be supplemented with the technical name as required by Chapter 3.3, special provision 274.

2.1.4.2. Samples of the substance shall be carried in accordance with the requirements applicable to the provisionally assigned proper shipping name, provided:

(a) The substance is not considered to be a substance prohibited for transport under 2.2.x.2 of Chapter 2.2 or under Chapter 3.2;

(e) The sample is not packed together with other goods.

CHAPTER 2.2

Class Specific Requirements

2.2.1. Class 1 Explosive substances and articles

2.2.1.1. Criteria

2.2.1.1.1. The heading of Class 1 covers:

(a) Explosive substances: solid or liquid substances (or mixtures of substances) capable by chemical reaction of producing gases at such a temperature and pressure and at such a speed as to cause damage to the surroundings.

Pyrotechnic substances: substances or mixtures of substances designed to produce an effect by heat, light, sound, gas or smoke or a combination of these as the result of non-detonating self-sustaining exothermic chemical reactions.

NOTES:

1. Substances which are not themselves explosive but which may form an explosive mixture of gas, vapour or dust are not substances of Class 1.

2. Also excluded from Class 1 are: water- or alcohol-wetted explosives of which the water or alcohol content exceeds the limits specified and those containing plasticizers - these explosives are assigned to Class 3 or Class 4.1 - and those explosives which, on the basis of their predominant hazard, are assigned to Class 5.2.

(b) Explosive articles: articles containing one or more explosive substances or pyrotechnic substances.

NOTE:

Devices containing explosive or pyrotechnic substances in such small quantity or of such a character that their inadvertent or accidental ignition or initiation during carriage would not cause any manifestation external to the device by projection, fire, smoke, heat or loud noise are not subject to the requirements of Class 1.

(c) Substances and articles not mentioned above which are manufactured with a view to producing a practical effect by explosion or a pyrotechnic effect.

2.2.1.1.2. Any substance or article having or suspected of having explosive properties shall be considered for assignment to Class 1 in accordance with the tests, procedures and criteria prescribed in Part I, Manual of Tests and Criteria.

A substance or article assigned to Class 1 can only be accepted for carriage when it has been assigned to a name or n.o.s. entry listed in table A of Chapter 3.2 and meets the criteria of the Manual of Tests and Criteria.

2.2.1.1.3. The substances and articles of Class 1 shall be assigned to a UN Number and a name or n.o.s. entry listed in table A of Chapter 3.2. Interpretation of the names of substances and articles in table A of Chapter 3.2 shall be based upon the glossary in 2.2.1.1.7.

Samples of new or existing explosive substances or articles carried for purposes including: testing, classification, research and development quality control, or as a commercial sample, other than initiating explosive, may be assigned to UN No 0190 SAMPLES, EXPLOSIVE.

The assignment of substances and articles not mentioned by name as such in table A of Chapter 3.2 to an n.o.s. entry or UN No 0190 SAMPLES, EXPLOSIVE as well as the assignment of certain substances the carriage of which is subject to a specific authorization by the competent authority according to the special requirements referred to in column (6) of table A of Chapter 3.2 shall be made by the competent authority of the country of origin. This competent authority shall also approve in writing the conditions of carriage of these substances and articles. If the country of origin is not a COTIF Member State, the classification and the conditions of carriage shall be recognized by the competent authority of the first COTIF Member State reached by the consignment.

2.2.1.1.4. Substances and articles of Class 1 shall be assigned to a division in accordance with 2.2.1.1.5 and to a compatibility group in accordance with 2.2.1.1.6. The division shall be based on the results of the tests described in section 2.3.0 and 2.3.1 applying the definitions in 2.2.1.1.5. The compatibility group shall be determined in accordance with the definitions in 2.2.1.1.6. The classification code shall consist of the division number and the compatibility group letter.

2.2.1.1.5. Definition of divisions

>TABLE>

NOTE:

The risk from articles of Division 1.6 is limited to the explosion of a single article.

2.2.1.1.6. Definition of compatibility groups of substances and articles

>TABLE>

NOTES:

1. Each substance or article, packed in a specified packaging, may be assigned to one compatibility group only. Since the criterion of compatibility group S is empirical, assignment to this group is necessarily linked to the tests for assignment of a classification code.

2. Articles of compatibility groups D and E may be fitted or packed together with their own means of initiation provided that such means have at least two effective protective features designed to prevent an explosion in the event of accidental functioning of the means of initiation. Such packages shall be assigned to compatibility groups D or E.

3. Articles of compatibility groups D and E may be packed together with their own means of initiation, which do not have two effective protective features (i.e. means of initiation assigned to compatibility group B), provided that they comply with mixed packing provision MP 21 of section 4.1.10. Such packages shall be assigned to compatibility groups D or E.

4. Articles may be fitted or packed together with their own means of ignition provided that the means of ignition cannot function during normal conditions of carriage.

5. Articles of compatibility groups C, D and E may be packed together. Such packages shall be assigned to compatibility group E.

2.2.1.1.7. Glossary of names

NOTES:

1. The descriptions in the glossary are not intended to replace the test procedures, nor to determine the hazard classification of a substance or article of Class 1. Assignment to the correct division and a decision on whether Compatibility Group S is appropriate shall be based on testing of the product in accordance with the Manual of Tests and Criteria, Part I or by analogy with similar products which have already been tested and assigned in accordance with the procedures of the Manual of Tests and Criteria.
