This Directive applies to the electromagnetic compatibility of vehicles covered in Article 1, being vehicles or trailers (hereinafter referred to as vehicle(s)) as supplied by the vehicle manufacturer and to components or separate technical units intended for fitment in vehicles. 2. Definitions 2.1. For the purposes of this Directive: 2.1.1. 'Electromagnetic compatibility' means the ability of a vehicle or component(s) or separate technical unit(s) to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment. 2.1.2. 'Electromagnetic disturbance' means any electromagnetic phenomenon which may degrade the performance of a vehicle or component(s) or separate technical unit(s). An electromagnetic disturbance may be electromagnetic noise, an unwanted signal or a change in the propagation medium itself. 2.1.3. 'Electromagnetic immunity' means the ability of a vehicle or component(s) or separate technical unit(s) to perform without degradation of performance in the presence of specified electromagnetic disturbances. 2.1.4. 'Electromagnetic environment' means the totality of electromagnetic phenomena existing at a given location. 2.1.5. 'Reference limit' means the nominal level to which type approval and conformity of production limit values are referenced. 2.1.6. 'Reference antenna' for the frequency range 20 to 80 MHz: means a shortened balanced dipole being a half wave resonant dipole at 80 MHz, and for the frequency range above 80 MHz: means a balanced half wave resonant dipole tuned to the measurement frequency. 2.1.7. 'Broadband emission' means an emission which has a bandwidth greater than that of a particular measuring apparatus or receiver. 2.1.8. 'Narrowband emission' means an emission which has a bandwidth less than that of a particular measuring apparatus or receiver. 2.1.9. 'Electrical/electronic system' means (an) electrical and/or electronic device(s) or set(s) of devices together with any associated electrical connections which form part of a vehicle but which are not intended to be type approved separately from the vehicle. 2.1.10. 'Electrical/electronic sub-assembly' (ESA) means an electrical and/or electronic device or set(s) of devices intended to be part of a vehicle, together with any associated electrical connections and wiring, which performs one or more specialized functions. An ESA may be approved at the request of a manufacturer as either a 'component' or a 'separate technical unit (STU)' (see Directive 70/156/EEC, Article 2). 2.1.11. 'Vehicle type' in relation to electromagnetic compatibility means vehicles which do not differ essentially in such respects as: 2.1.11.1. the overall size and shape of the engine compartment; 2.1.11.2. the general arrangement of the electrical and/or electronic components and the general wiring arrangement; 2.1.11.3. the primary material of which the body or shell (if applicable) of the vehicle is constructed (for example, a steel, aluminium or fibreglass body shell). The presence of panels of different material does not change the vehicle type provided the primary material of the body is unchanged. However, such variations must be notified. 2.1.12. An 'ESA type' in relation to electromagnetic compatibility means ESAs which do not differ in such essential respects as: 2.1.12.1. the function performed by the ESA; 2.1.12.2. the general arrangement of the electrical and/or electronic components, if applicable. 3. Application for EEC type-approval 3.1. Approval of a vehicle type 3.1.1. The application for approval of a vehicle type, with regard to its electromagnetic compatibility pursuant to Article 3 (4) of Directive 70/156/EEC shall be submitted by the vehicle manufacturer. 3.1.2. A model for the information document is given in Annex IIA. 3.1.3. The vehicle manufacturer shall draw up a schedule describing all projected combinations of relevant vehicle electrical/electronic systems or ESAs, body styles (1), variations in body material (1), general wiring arrangements, engine variations, left-hand/right-hand drive versions and wheelbase versions. Relevant vehicle electrical/electronic systems or ESAs are those which may emit significant broadband or narrowband radiation and/or those which are involved in the driver's direct control (see paragraph 6.4.2.3 of this Annex) of the vehicle. 3.1.4. A representative vehicle shall be selected from this schedule for the purpose of being tested, in mutual agreement between the manufacturer and the competent authority. This vehicle shall represent the vehicle type (see Appendix 1 to Annex IIA). The choice of vehicle shall be based on the electrical/electronic systems offered by the manufacturer. One more vehicle may be selected from this schedule for the purpose of being tested if it is considered by mutual agreement between the manufacturer and the competent authority that different electrical/electronic systems are included which are likely to have a significant effect on the vehicle's electromagnetic compatibility compared with the first representative vehicle. 3.1.5. The choice of the vehicle(s) in conformity with paragraph 3.1.4 is limited to vehicle/electrical/electronic system combinations intended for actual production. 3.1.6. The manufacturer may supplement the application with a report from tests which have been carried out. Any such data provided may be used by the approval authority for the purpose of drawing up the type-approval certificate. 3.1.7. If the technical service responsible for the type-approval test carries out the test itself, then a vehicle representative of the type to be approved, according to paragraph 3.1.4 shall be provided. 3.2. Approval of a type of ESA 3.2.1. The application for approval of a type of ESA with regard to its electromagnetic compatibility pursuant to Article 3 (4) of Directive 70/156/EEC shall be submitted by the vehicle manufacturer or by the manufacturer of the ESA. 3.2.2. A model for the information document is given in Annex IIB. 3.2.3. The manufacturer may supplement the application with a report from tests which have been carried out. Any such data provided may be used by the approval authority for the purpose of drawing up the type-approval certificate. 3.2.4. If the technical service responsible for the type-approval test carries out the test itself, then a sample of the ESA system representative of the type to be approved shall be provided, if necessary, after discussion with the manufacturer on, for example, possible variations in the layout, number of components, number of sensors. If the technical service deems it necessary, it may select a further sample. 3.2.5. The sample(s) must be clearly and indelibly marked with the manufacturer's trade name or mark and the type designation. 3.2.6. Where applicable, any restrictions on use should be identified. Any such restrictions should be included in Annexes IIB and/or IIIB. 4. Type-approval 4.1. Routes to type-approval 4.1.1. Type-approval of a vehicle The following alternative routes to type-approval of a vehicle may be used at the discretion of the vehicle manufacturer. 4.1.1.1. Approval of a vehicle installation A vehicle installation may achieve type-approval directly by following the provisions laid down in paragraph 6 of this Annex. If this route is chosen by a vehicle manufacturer, no separate testing of electrical/electronic systems or ESAs is required. 4.1.1.2. Approval of vehicle type by testing of individual ESAs A vehicle manufacturer may obtain approval for the vehicle by demonstrating to the approval authority that all the relevant (see paragraph 3.1.3 of this Annex) electrical/electronic systems or ESAs have individually been approved in accordance with this Directive and have been installed in accordance with any conditions attached thereto. 4.1.1.3. A manufacturer, if he wishes, may obtain approval to this Directive if the vehicle has no equipment of the type which is subject to immunity or emission tests. The vehicle shall have no systems as specified in paragraph 3.1.3 (immunity) and no spark ignition equipment. Such approvals do not require testing. 4.1.2. Type-approval of an ESA Type-approval may be granted to an ESA to be fitted either to any vehicle type or to a specific vehicle type or types requested by the manufacturer. ESAs involved in the direct control of vehicles will normally receive type-approval in conjunction with a vehicle manufacturer. 4.2. Granting of type-approval 4.2.1. Vehicle 4.2.1.1. If the representative vehicle fulfils the requirements of this Directive, EEC type-approval pursuant to Article 4 (3), and if applicable, Article 4 (4) of Directive 70/156/EEC shall be granted. 4.2.1.2. A model for the EEC type-approval certificate is given in Annex IIIA. 4.2.2. ESA 4.2.2.1. If the representative ESA system(s) fulfil(s) the requirements of this Directive, EEC type-approval pursuant to Article 4 (3), and if applicable, Article 4 (4) of Directive 70/156/EEC shall be granted. 4.2.2.2. A model for the EEC type-approval certificates is given in Annex IIIB. 4.2.3. In order to draw up the certificates referred to in paragraph 4.2.1.2 or 4.2.2.2, the competent authority of the Member State granting the approval may use a report prepared by an approved or recognized laboratory or in accordance with the provisions of this Directive. 4.3. Amendments to approvals 4.3.1. In the case of amendments to approvals granted pursuant to this Directive, the provisions of Article 5 of Directive 70/156/EEC shall apply. 4.3.2. Amendment of a vehicle type-approval by ESA addition or substitution. 4.3.2.1. Where a vehicle manufacturer has obtained approval for a vehicle installation and wishes to fit an additional or substitutional electrical/electronic system or ESA which has already received approval pursuant to this Directive, and which will be installed in accordance with any conditions attached thereto, the vehicle approval may be amended without further testing. The additional or substitutional electrical/electronic system or ESA shall be considered as part of the vehicle for conformity of production purposes. 4.3.2.2. Where the additional or substitutional part(s) has (have) not received approval pursuant to this Directive, and if testing is considered necessary, the whole vehicle shall be deemed to comply if the new or revised part(s) can be shown to comply with the relevant requirements of paragraph 6 or if, in a comparative test, the new part can be shown not to be likely to adversely affect compliance of the vehicle type. 4.3.2.3. The addition by a vehicle manufacturer to an approved vehicle of standard domestic or business equipment, other than mobile communication equipment (*) which complies with Directive 89/336/EEC, and is installed according to the recommendations of the equipment and vehicle manufacturers, or the substitution or removal thereof, shall not invalidate the vehicle approval. This shall not preclude vehicle manufacturers fitting communication equipment with suitable installations guidelines developed by the vehicle manufacturer and/or manufacturer(s) of such communication equipment. The vehicle manufacturer shall provide evidence (if requested by the test authority) that vehicle performance is not adversely affected by such transmitters. This can be a statement that the power levels and installation are such that the immunity levels of this Directive offer sufficient protection when subject to transmission alone, i.e. excluding transmission in conjunction with the tests specified in paragraph 6. This Directive does not authorize the use of a communication transmitter when other requirements on such equipment or its use apply. A vehicle manufacturer may refuse to install in his vehicle standard domestic or business equipment which complies with Directive 89/336/EEC. 5. Marking 5.1. Every ESA conforming to a type approved pursuant to this Directive shall bear an EEC type-approval mark. 5.2. This mark shall consist of a rectangle surrounding the letter 'e' followed by the distinguishing number or letters of the Member State which has granted type-approval: 1 Germany 2 France 3 Italy 4 the Netherlands 6 Belgium 9 Spain 11 the United Kingdom 13 Luxembourg 18 Denmark 21 Portugal 23 Greece IRL Ireland It must also include in the vicinity of the rectangle the four-digit sequential number (with leading zeros as applicable) - hereinafter referred to as 'base approval number' - contained in Section 4 of the type-approval number shown on the EEC type-approval certificate issued for the type of device in question (see Annex IIIB), preceded by the two figures indicating the sequence number assigned to the most recent major technical amendment to Directive 72/245/EEC on the date EEC component type-approval was granted. In this Directive the sequence number is 02. 5.3. The EEC type-approval mark must be affixed to the main part of the ESA (e.g. the electronic control unit) in such a way as to be clearly legible and indelible. 5.4. An example of the EEC type-approval mark is shown in Appendix 7. 5.5. No marking is required for electrical/electronic systems included in vehicle types approved by this Directive. 5.6. Markings on ESAs in compliance with paragraph 5.3 need not be visible when the ESA is installed in a vehicle. 6. Specifications 6.1. General specification 6.1.1.

If the conformity of a vehicle, component or STU taken from the series is being verified, production shall be deemed to conform to the requirements of this Directive in relation to broadband radiated emissions and narrowband radiated emissions if the levels measured do not exceed by more than 2 dB, (25 %) the reference limits prescribed in paragraphs 6.2.2.1, 6.2.2.2, 6.3.2.1 and 6.3.2.2 (as appropriate). 7.3.2. If the conformity of a vehicle, component or STU taken from the series is being verified, production shall be deemed to conform to the requirements of this Directive in relation to immunity to electromagnetic radiation if the vehicle, component or STU does not exhibit any degradation relating to the direct control of the vehicle which could be observed by the driver or other road user when the vehicle, component or STU is in the state defined in Annex VI, paragraph 4, and subjected to a field strength, expressed in volts/m, up to 80 % of the reference limits prescribed in paragraph 6.4.2.1 of this Annex. 8. Exceptions 8.1. Where a vehicle or electrical/electronic system or ESA does not include an electronic oscillator with an operating frequency greater than 9 kHz, it shall be deemed to comply with paragraph 6.3.2 or 6.6.2 of Annex I and with Annexes V and VIII. 8.2. Vehicles which do not have electrical/electronic systems or ESAs involved in the direct control of the vehicle need not be tested for immunity and shall be deemed to comply with paragraph 6.4 of Annex I and with Annex VI to this Directive. 8.3. ESAs whose functions are not involved in the direct control of the vehicle need not be tested for immunity and shall be deemed to comply with paragraph 6.7 of Annex I and with Annex IX to this Directive. 8.4. Electrostatic discharge For vehicles fitted with tyres, the vehicle body/chassis can be considered to be an electrically isolated structure. Significant electrostatic forces in relation to the vehicle's external environment only occur at the moment of occupant entry into or exit from the vehicle. As the vehicle is stationary at these moments, no type-approval test for electrostatic discharge is deemed necessary. 8.5. Conducted transients Since during normal driving, no external electrical connections are made to vehicles, no conducted transients are generated in relation to the external environment. The responsibility of ensuring that equipment can tolerate the conducted transients within a vehicle, e.g. due to load switching and interaction between systems, lies with the manufacturer. No type-approval test for conducted transients is deemed necessary.

The test method described in this Annex shall only be applied to vehicles. 1.2. Measuring apparatus The measuring equipment shall comply with the requirements of publication No 16-1 (93) of the International Special Committee on Radio Interference (CISPR). A quasi-peak detector shall be used for the measurement of braodband electromagnetic emissions in this Annex, or if a peak detector is used an appropriate correction factor shall be used depending on the spark pulse rate. 1.3. Test method This test is intended to measure the broadband emissions generated by spark ignition systems. Two alternative reference antenna distances are permissible: 10 or 3 m from the vehicle. In either case the requirements of paragraph 3 of this Annex shall be complied with. 2. Expression of results The results of measurements shall be expressed in dB microvolt/m (microvol/m) for 120 kHz band width. If the actual band width B (expressed in kHz) of the measuring apparatus differs from 120 kHz, the readings taken in microvolts/m shall be converted to 120 kHz band width through multiplication by a factor 120/B. 3. Measuring location 3.1. The test site shall be a level, clear area free from electromagnetic reflecting surfaces within a circle of minimum radius 30 m measured from a point midway between the vehicle and the antenna (see Figure 1 of Appendix 1 to this Annex). 3.2. The measuring set, test hut, or vehicle in which the measurement set is located may be within the test site, but only in the permitted region shown in Figure 1 in Appendix 1 to this Annex. Other measuring antennae are allowed within the test area, at a minimum distance of 10 m both from receiving antenna and the vehicle under test, provided that it can be shown that the test results will not be affected. 3.3. Enclosed test facilities may be used if correlation can be shown between the enclosed test facility and an outdoor site. Enclosed test facilities do not need to meet the dimensional requirements of Figure 1 in Appendix 1 of this Annex other than the distance from the antenna to the vehicle and the height of the antenna. Neither do they need to have ambient emissions checked before or after the test as indicated in paragraph 3.4 of this Annex. 3.4. Ambient To ensure that there is no extraneous noise or signal of a magnitude sufficient to affect materially the measurement, measurements shall be taken before and after the main test. If the vehicle is present when ambient measurements are taken, it will be necessary to ensure that any emissions from the vehicle do not affect significantly the ambient measurements, for example by removing the vehicle from the test area, removing the ignition key, or disconnecting the battery. In both of the measurements, the extraneous noise or signal shall be at least 10 dB below the limits of interference given in paragraph 6.2.2.1 or 6.2.2.2 (as appropriate) of Annex I, except for intentional narrowband ambient transmissions. 4. Vehicle state during tests 4.1. Engine The engine shall be running at its normal operating temperature and the transmission shall be in neutral. If for practical reasons this cannot be achieved, alternative arrangements mutually agreed between the manufacturer and the test authorities may be made. Care shall be taken to ensure that the speed setting mechanism does not influence electromagnetic radiations. During each measurement, the engine shall be operated as follows: >TABLE> 4.2. Testing shall not be conducted while rain or other precipitation is falling on the vehicle or within 10 minutes after such precipitation has stopped. 5. Antenna type, position and orientation 5.1. Antenna type Any antenna may be used provided it can be normalized to the reference antenna. The method described in CISPR publication No 12, Edition 3, Appendix A, may be used to calibrate the antenna. 5.2. Height and distance of measurement 5.2.1. Height 5.2.1.1. 10 m test The phase centre of the antenna shall be 3,00 ± 0,05 m above the plane on which the vehicle rests. 5.2.1.2. 3 m test The phase centre of the antenna shall be 1,80 ± 0,05 m above the plane on which the vehicle rests. 5.2.1.3. No part of any antenna's receiving elements shall be closer than 0,25 m to the plane on which the vehicle rests. 5.2.2. Distance of measurement 5.2.2.1. 10 m test The horizontal distance from the tip or other appropriate point of the antenna defined during the normalization procedure described in paragraph 5.1 to this Annex to the outer body surface of the vehicle shall be 10,0 ± 0,2 m. 5.2.2.2. 3 m test The horizontal distance from the tip or other appropriate point of the antenna defined during the normalization procedure described in paragraph 5.1 to this Annex to the outer body surface of the vehicle shall be 3,00 ± 0,05 m. 5.2.2.3. If the test is carried out in a facility enclosed for radio frequency electromagnetic screening purposes, the antenna's receiving elements shall be no closer than 1,0 m to any radio absorbent material and no closer than 1,5 m to the wall of the enclosed facility. There must be no absorbent material between the receiving antenna and vehicle under test. 5.3. Antenna location relative to vehicle The antenna shall be located successively on the left and right-hand sides of the vehicle, with the antenna parallel to the plane of longitudinal symmetry of the vehicle and in line with the engine mid-point (see Figure 1 in Appendix 1 to this Annex). 5.4. Antenna position At each of the measuring points, readings shall be taken both with the antenna in a horizontal and in a vertical polarization (see Figure 2 in Appendix 1 to this Annex). 5.5. Readings The maximum of the four readings taken in accordance with paragraphs 5.3 and 5.4 at each spot frequency shall be taken as the characteristic reading at the frequency at which the measurements were made. 6. Frequencies 6.1. Measurements Measurements shall be made throughout the 30 to 1 000 MHz frequency range. To confirm that the vehicle meets the requirements of this Annex, the Testing Authority shall test at up to 13 frequencies in the range, e.g. 45, 65, 90, 120, 150, 190, 230, 280, 380, 450, 600, 750, 900 MHz. In the event that the limit is exceeded during the test, investigations shall be made to ensure that this is due to the vehicle and not to background radiation. 6.1.1. The limits apply throughout the frequency range 30 to 1 000 MHz. 6.1.2. Measurements can be performed with either quasi-peak or peak detectors. The limits given in Annex I, paragraphs 6.2 and 6.5 are for quasi-peak. If peak is used, add 38 dB for 1 MHz bandwith or subtract 22 dB for 1 kHz band width. 6.2. Tolerances >TABLE> The tolerances apply to frequencies quoted and are intended to avoid interference from transmissions operating on or near the nominal spot frequencies during the time of measurement.

General 1.1. The test method described in this Annex shall only be applied to vehicles. 1.2. Measuring apparatus The measuring equipment shall comply with the requirements of publication No 16-1 (93), of the International Special Committee on Radio Interference (CISPR). An average detector or a peak detector shall be used for the measurement of radiated narrowband electromagnetic emissions in this Annex. 1.3. Test method 1.3.1. This test is intended to measure narrowband electromagnetic emissions such as might emanate from a microprocessor-based system or other narrowband source. 1.3.2. As an initial step the levels of emissions in the FM frequency band (88 to 108 MHz) shall be measured at the vehicle broadcast radio antenna with equipment as specified in paragraph 1.2. If the level specified in paragraph 6.3.2.4 of Annex I is not exceeded, then the vehicle shall be deemed to comply with the requirements of this Annex in respect of that frequency band and the full test shall not be carried out. 1.3.3. In the full test procedure two alternative antenna distances are permissible: 10 or 3 m from the vehicle. In either case the requirements of paragraph 3 of this Annex shall be complied with. 2. Expression of results The results of measurements shall be expressed in dB microvolts/m (microvolts/m). 3. Measuring location 3.1. The test site shall be a level, clear area free from electromagnetic reflecting surfaces within a circle of minimum radius 30 m measured from a point midway between the vehicle and the antenna (see Figure 1 of Appendix 1 to Annex IV). 3.2. The measuring set, test hut, or vehicle in which the measurement set is located may be within the test site, but only in the permitted region shown in Figure 1 of Appendix 1 to Annex IV. Other measuring antennae are allowed within the test area, at a minimum distance of 10 m both from receiving antenna and the vehicle/STU under test, provided that it can be shown that the test results will not be affected. 3.3. Enclosed test facilities may be used if correlation can be shown between the enclosed test facility and an outdoor site. Enclosed test facilities do not need to meet the dimensional requirements of Figure 1 in Appendix 1 of Annex IV other than the distance from the antenna to the vehicle and the height of the antenna. Neither do they need to have ambient emissions checked before or after the test as indicated in paragraph 3.4 of this Annex. 3.4. Ambient To ensure that there is no extraneous noise or signal of a magnitude sufficient to affect materially the measurement, ambient measurements shall be taken before and after the main test. It will be necessary to ensure that any emissions from the vehicle do not affect significantly the ambient measurements, for example by removing the vehicle from the test area, removing the ignition key, or disconnecting the battery(ies). In both of the measurements, the extraneous noise or signal shall be at least 10 dB below the limits of interference given in paragraph 6.3.2.1 or 6.3.2.2 (as appropriate) of Annex I, except for intentional narrowband ambient transmissions. 4. Vehicle state during tests 4.1. The vehicle's electronic systems shall all be in normal operating mode with the vehicle stationary. 4.2. The ignition shall be switched on. The engine shall not be operating. 4.3. Measurements shall not be made while rain or other precipitation is falling on the vehicle or within 10 minutes after such precipitation has stopped. 5. Antenna type, position and orientation 5.1. Antenna type Any antenna may be used provided that it can be normalized to the reference antenna. The method described in the CISPR 12 publication, Edition 3, Appendix A, may be used to calibrate the antenna. 5.2. Height and distance of measurement 5.2.1. Height 5.2.1.1. 10 m test The phase centre of the antenna shall be 3,00 ± 0,05 m above the plane on which the vehicle rests. 5.2.1.2. 3 m test The phase centre of the antenna shall be 1,80 ± 0,05 m above the plane on which the vehicle rests. 5.2.1.3. No part of any antenna's receiving elements shall be closer than 0,25 m to the plane on which the vehicle rests. 5.2.2.

If the test is carried out in a facility enclosed for radio frequency electromagnetic screening purposes, the antenna's receiving elements shall be no closer than 1,0 m to any radio absorbent material and no closer than 1,5 m to the wall of the enclosed facility. There must be no absorbent material between the receiving antenna and vehicle under test. 5.3. Antenna location relative to vehicle The antenna shall be located successively on the left and right-hand sides of the vehicle with the antenna parallel to the plane of longitudinal symmetry of the vehicle and in line with the engine mid-point (see Figure 2 in Appendix 1 to Annex IV). 5.4. Antenna position At each of the measuring points, readings shall be taken both with the antenna in a horizontal and in a vertical polarization (see Figure 2 in Appendix 1 to Annex IV). 5.5. Readings The maximum of the four readings taken in accordance with paragraphs 5.3 and 5.4 at each spot frequency shall be taken as the characteristic reading at the frequency at which the measurements are made. 6. Frequencies 6.1. Measurements Measurements shall be made throughout the 30 to 1 000 MHz frequency range. This range shall be divided into 13 bands. In each band one spot frequency may be tested to demonstrate that the required limits are satisfied. To confirm that the vehicle meets the requirements of this Annex, the testing authority shall test at one such point in each of the following 13 frequency bands: 30 to 50, 50 to 75, 75 to 100, 100 to 130, 130 to 165, 165 to 200, 200 to 250, 250 to 320, 320 to 400, 400 to 520, 520 to 660, 660 to 820, 820 to 1 000 MHz. In the event that the limit is exceeded during the test, investigations shall be made to ensure that this is due to the vehicle and not to background radiation. ANNEX VI METHOD OF TESTING FOR IMMUNITY OF VEHICLES TO ELECTROMAGNETIC RADIATION 1. General 1.1. The test method described in this Annex shall only be applied to vehicles. 1.2. Test method This test is intended to demonstrate the immunity to degradation in the direct control of the vehicle. The vehicle shall be subject to electromagnetic fields as described in this Annex. The vehicle shall be mnitored during the tests. 2. Expression of results For the test described in this Annex, field strengths shall be expressed in volts/m. 3. Measuring location The test facility shall be capable of generating the field strengths over the frequency ranges defined in this Annex. The test facility shall comply with (national) legal requirements regarding the emission of electromagnetic signals. Care shall be taken so that the control and monitoring equipment shall not be affected by radiated fields in such a way as to invalidate the tests. 4. Vehicle state during tests 4.1. The vehicle shall be in an unladen condition except for necessary test equipment. 4.1.1. The engine shall normally turn the driving wheels at a steady speed of 50 km/h if there is no technical reason for a manufacturer to prefer a different speed. The vehicle shall be on an appropriately loaded dynamometer or alternatively supported on insulated axle stands with minimum ground clearance if no dynamometer is available. Where appropriate, transmission shafts may be disconnected (e.g. trucks). 4.1.2. Headlamps shall be on dipped beam. 4.1.3. Left or right direction indicator shall be operating. 4.1.4. All other systems which affect the driver's control of the vehicle shall be (on) as in normal operation of the vehicle. 4.1.5. The vehicle shall not be electrically connected to the test area and no connections shall be made to the vehicle from any equipment, except as required by paragraph 4.1.1 or 4.2. Tyre contact with the test area floor shall not be considered to be an electrical connection. 4.2. If there are vehicle electrical/electronic systems which form an integral part of the direct control of the vehicle, which will not operate under the conditions described in paragraph 4.1, it will be permissible for the manufacturer to provide a report or additional evidence to the testing authority that the vehicle electrical/electronic system meets the requirements of this Directive. Such evidence shall be retained in the type-approval documentation. 4.3. Only non-perturbing equipment shall be used while monitoring the vehicle. The vehicle exterior and the passenger compartment shall be monitored to determine whether the requirements of this Annex are met (e.g. by using (a) video camera(s)). 4.4. The vehicle shall normally face a fixed antenna. However, where the electronic control units and the associated wiring harness are predominantly in the rear of the vehicle, the test should normally be carried out with the vehicle facing away from the antenna. In the case of long vehicles (i.e. excluding cars and light vans), which have electronic control units and associated wiring harness predominantly towards the middle of the vehicle, a reference point (see paragraph 5.4 of this Annex) may be established based on either the right side surface or the left side surface of the vehicle.

The associated measuring equipment shall be sited outside the screen room. At each desired test frequency, a level of power shall be fed into the stripline to produce the required field strength at the antenna. This level of forward power, or another parameter directly related to the forward power required to define the field, shall be used for type approval tests unless changes occur in the facilities or equipment which necessitate this procedure being repeated. 7.3.2.4.

However, if any part of the ESA under test is intended to be electrically bonded to a vehicle's metal bodywork, that part shall be placed on a ground plane and shall be electrically bonded to the ground plane. The ground plane shall be a metallic sheet with a minimum thickness of 0,5 mm. The minimum size of the ground plane depends on the size of the ESA under test but shall allow for the distribution of the ESA's wiring harness and components. The ground plane shall be connected to the protective conductor of the earthing system. The ground plane shall be situated at a height of 1,0 ± 0,1 m above the test facility floor and shall be parallel to it. 8.2.1.2. The ESA under test shall be arranged and connected according to its requirements. The power supply harness shall be positioned along, and within 100 mm of, the edge of the ground plane/table closest to the antenna. 8.2.1.3. The ESA under test shall be connected to the grounding system according to the manufacturer's installation specification, no additional grounding connections shall be permitted. 8.2.1.4. The minimum distance between the ESA under test and all other conductive structures, such as walls of a shielded area (with the exception of the ground plane/table underneath the test object) must be 1,0 m. 8.2.1.5. The dimension of any ground plane shall be 2,25 square meter or larger in area with the smaller side no less than 750 mm. The ground plane shall be bonded to the chamber with bonding straps such that the DC bonding resistance shall not exceed 2,5 milliohms. 8.2.2. Installation of ESA under test For large equipment mounted on a metal test stand, the test stand shall be considered a part of the ground plane for testing purposes and shall be bonded accordingly. The faces of the test sample shall be located at a minimum of 200 mm from the edge of the ground plane. All leads and cables shall be a minimum of 100 mm from the edge of the ground plane and the distance to the ground plane (from the lowest point of the harness) shall be 50 ± 5 mm above the ground plane. Power shall be applied to the ESA under test via an (5 µ H/50 `) artificial network (AN). 8.3. Field generating device type, position and orientation 8.3.1. Field generating device type 8.3.1.1. The field generating device type(s) shall be chosen such that the desired field strength is achieved at the reference point (see paragraph 8.3.4 of this Annex) at the appropriate frequencies. 8.3.1.2. The field generating device(s) may be (an) antenna(s) or a plate antenna. 8.3.1.3. The construction and orientation of any field generating device shall be such that the generated field is polarised: from 20 to 1 000 MHz horizontally or vertically. 8.3.2. Height and distance of measurement 8.3.2.1. Height The phase centre of any antenna shall be 150 ± 10 mm above the ground plane on which the ESA under test rests. No parts of any antenna's radiating elements shall be closer than 250 mm to the floor of the facility. 8.3.2.2. Distance of measurement 8.3.2.2.1. In-service conditions may best be approximated by placing the field generating device as far from the ESA as practical. This distance will typically lie within the range 1 to 5 m. 8.3.2.2.2. If the test is carried out in an enclosed facility, the field generating device's radiating elements shall be no closer than 0,5 m to any radio absorbent material and no closer than 1,5 m to the wall of the facility. There shall be no absorbent material interposed between the transmitting antenna and the ESA under test. 8.3.3. Antenna location relative to ESA under test 8.3.3.1. The field generating device's radiating elements shall not be closer than 0,5 m to the edge of the ground plane. 8.3.3.2. The phase centre of the field generating device shall be on a plane which: (a) is perpendicular to the ground plane; (b) bisects the edge of the ground plane and the midpoint of the principal portion of the wiring harness; and (c) is perpendicular to the edge of the ground plane and the principal portion of the wiring harness. The field generating device shall be placed parallel to this plane (see Figures 1 and 2 of Appendix 4 to this Annex). 8.3.3.3. Any field generating device which is placed over the ground plane or ESA under test shall extend over the ESA under test. 8.3.4. Reference point For the purpose of this Annex the reference point is the point at which the field strength shall be established and shall be defined as follows: 8.3.4.1. at least 1 m horizontally from the antenna phase centre or at least 1 m vertically from the radiating elements of a plate antenna; 8.3.4.2. on a plane which: (a) is perpendicular to the ground plane; (b) is perpendicular to the edge of the ground plane along which the principal portion of the wiring harness runs; and (c) bisects the edge of the ground plane and the midpoint of the principal portion of the wiring harness; (d) coincident with the midpoint of the principal portion of the harness which runs along the edge of the ground plane closest to the antenna; 8.3.4.3. 150 ± 10 mm above the ground plane. 8.4. Generation of required field strength: test methodology 8.4.1. the 'substitution method' shall be used to establish the test field conditions. 8.4.2. Substitution method At each desired test frequency, a level of power shall be fed into the field generating device to produce the required field strength at the reference point (as defined in paragraph 8.3.4 in the test area with the ESA under test absent), this level of forward power, or another parameter directly related to the forward power required to define the field, shall be measured and the results recorded. These results shall be used for type approval tests unless changes occur in the facilities or equipment which necessitates this procedure being repeated. 8.4.3. Extraneous equipment must be a minimum of 1 m from the reference point during calibration. 8.4.4. Field strength measuring device A suitable compact field strength measuring device shall be used to determine the field strength during the calibration phase of the substitution method. 8.4.5. The phase centre of the field strength measuring device shall be positioned at the reference point. 8.4.6. The ESA under test which may include an additional ground plane shall then be introduced into the test facility and positioned in accordance with the requirements of paragraph 8.3. If a second ground plane is used, then it shall be within 5 mm of the bench ground plane and electrically bounded to it. The required forward power defined in paragraph 8.4.2 at each frequency as defined in paragraph 5 shall then be applied to the field generating device. 8.4.7. Whatever parameter was chosen in paragraph 8.4.2 to define the field, the same parameter shall be used to determine the field strength during the test. 8.5. Field strength contour 8.5.1. During the calibration phase of the substitution method (prior to an ESA under test being introduced into the test area), the field strength shall not be less than 50 % of the nominal field strength 0,5 ± 0,05 m either side of the reference point on a line parallel to the edge of the ground plane nearest to the antenna and passing through the reference point. 9. TEM cell testing 9.1. Test method The TEM (transverse electromagnetic mode) cell generates homogeneous fields between the internal conductor (septum) and housing (ground plane). It is used for testing ESAs (see Figure 1 of Appendix 3 to this Annex)). 9.2. Field strength measurement in a TEM cell 9.2.1. The electric field in the TEM cell shall be determined by using the equation: >START OF GRAPHIC> |E| = √(P × Z) d>END OF GRAPHIC> E = Electric field (volts/metre) P = Power flowing into cell (W) Z = Impedance of cell (50 `) d = Separation distance (metres) between the upper wall and the plate (septum). 9.2.2. Alternatively an appropriate field strength sensor shall be placed in the upper half of the TEM cell. In this part of the TEM cell the electronic control unit(s) has only a small influence on the test field. The output of this sensor shall determine the field strength. 9.3. Dimensions of TEM cell In order to maintain a homogeneous field in the TEM cell and to obtain repeatable measurement results, the test object shall not be larger than one-third of the cell inside height. Recommended TEM cell dimensions are given in Appendix 3, Figures 2 and 3 to this Annex. 9.4. Power, signal and control wires The TEM cell shall be attached to a co-axial socket panel and connected as closely as possible to a plug connector with an adequate number of pins. The supply and signal leads from the plug connector in the cell wall shall be directly connected to the test object. The external components such as sensors, power supply and control elements can be connected: (a) to a screened peripheral; (b) to a vehicle next to the TEM cell; or (c) directly to the screened patchboard. Screened cables must be used in connecting the TEM cell to the peripheral or the vehicle if the vehicle or peripheral is not in the same or adjacent screened room. 10. Bulk current injection testing 10.1. Test method This is a method of carrying out immunity tests by inducing currents directly into a wiring harness using a current injection probe. The injection probe consists of a coupling clamp through which the cables of the ESA under test are passed. Immunity tests can then be carried out by varying the frequency of the induced signals. The ESA under test may be installed on a ground plane as in paragraph 8.2.1 or in a vehicle in accordance with the vehicle design specification. 10.2. Calibration of bulk current injection probe prior to commencing tests The injection probe shall be mounted in a calibration jig. Whilst sweeping the test frequency range, the power required to achieve the current specified in Annex I, paragraph 6.7.2.1 shall be monitored. This method calibrates the bulk current injection system forward power versus current prior to testing, and it is this forward power which shall be applied to the injection probe when connected to the ESA under test via the cables used during calibration. It should be noted that the monitored power applied to the injection probe is the forward power. 10.3. Installation of the ESA under test For an ESA mounted on a ground plane as in paragraph 8.2.1 all cables in the wiring harness should be terminated as realistically as possible and preferably with real loads and actuators. For both vehicle mounted and ground plane mounted ESAs the current injection probe shall be mounted in turn around all the wires in the wiring harness to each connector and 150 ± 10mm from each connector of the ESA under test electronic control units (ECU), instrument modules or active sensors as illustrated in Figure 1 of Appendix 2. 10.4. Power, signal and control wires For an ESA under test mounted on a ground plane as in paragraph 8.2.1, a wiring harness shall be connected between an artificial network (AN) and the principal electronic control unit (ECU). This harness shall run parallel to the edge of the ground plane and 200 mm minimum from its edge. This harness shall contain the power feed wire which is used to connect the vehicle battery to this ECU and the power return wire if used on the vehicle. The distance from the ECU to the AN shall be 1,0 ± 0,1 m or shall be the harness length between the ECU and the battery as used on the vehicle, if known, whichever is the shorter. If a vehicle harness is used then any line branches which occur in this length shall be routed along the ground plane but perpendicular away from the edge of the ground plane. Otherwise the ESA under test wires which are in this length shall break out at the AN.

Whereas Directive 72/245/EEC is one of the separate directives of the EEC type-approval procedure which was established pursuant to Directive 70/156/EEC; whereas, consequently, the provisions laid down in Directive 70/156/EEC relating to vehicle systems, components and separate technical units apply to this Directive;

Whereas, in particular, Articles 3 (4) and 4 (3) of Directive 70/156/EEC require each separate directive to have attached to it an information document incorporating the relevant items of Annex I to that Directive and also a type-approval certificate based on Annex VI thereto in order that type-approval may be computerized;

Whereas Directive 72/245/EEC contained the earliest measures endeavouring to bring about a basic electromagnetic compatibility regarding radio interference, since which time technical progress has increased the complexity and diversity of electrical and electronic equipment;

Whereas, in view of the increasing concern about the technological developments in electrical and electronic equipment and the need to ensure the general compatibility of different electrical and electronic equipment, Council Directive 89/336/EEC (5), as last amended by Directive 93/68/EEC (6), laid down general provisions regarding electromagnetic compatibility for all products;

Whereas Directive 89/336/EEC established the rule that, in so far as protection requirements specified in that Directive were harmonized, its general provisions would not apply or would cease to apply with regard to apparatus covered by specific directives;

Whereas in the field of vehicles, their components and separate technical units, it is necessary to envisage a specific directive within the framework of the system for European type-approval which provides for approvals granted by designated national authorities to harmonized technical requirements;

Whereas Directive 72/245/EEC should become such a specific directive;

Whereas reference is made to electromagnetic compatibility in other directives relating to vehicles, their components and separate technical units, within the framework of Directive 70/156/EEC;

Whereas the technical requirements relating to the radio interference (electromagnetic compatibility) of vehicles, their components and systems should be governed from 1 January 1996 solely by the provisions of Directive 72/245/EEC;

Whereas it is necessary to amend Directive 70/156/EEC to reflect the extension of Directive 72/245/EEC to all vehicle categories;

Whereas it is necessary to refer to Council Directive 72/306/EEC (1), as amended by Directive 89/491/EEC, in order to distinguish between spark and compression ignition engines;

Whereas the measures provided for in this Directive are in accordance with the opinion of the Committee for Adaptation to Technical Progress established by Directive 70/156/EEC,

3.1.4. A representative vehicle shall be selected from this schedule for the purpose of being tested, in mutual agreement between the manufacturer and the competent authority. This vehicle shall represent the vehicle type (see Appendix 1 to Annex IIA). The choice of vehicle shall be based on the electrical/electronic systems offered by the manufacturer. One more vehicle may be selected from this schedule for the purpose of being tested if it is considered by mutual agreement between the manufacturer and the competent authority that different electrical/electronic systems are included which are likely to have a significant effect on the vehicle's electromagnetic compatibility compared with the first representative vehicle.

3.1.5. The choice of the vehicle(s) in conformity with paragraph 3.1.4 is limited to vehicle/electrical/electronic system combinations intended for actual production.

3.1.6. The manufacturer may supplement the application with a report from tests which have been carried out. Any such data provided may be used by the approval authority for the purpose of drawing up the type-approval certificate.

3.1.7. If the technical service responsible for the type-approval test carries out the test itself, then a vehicle representative of the type to be approved, according to paragraph 3.1.4 shall be provided.

3.2. Approval of a type of ESA

3.2.1. The application for approval of a type of ESA with regard to its electromagnetic compatibility pursuant to Article 3 (4) of Directive 70/156/EEC shall be submitted by the vehicle manufacturer or by the manufacturer of the ESA.

3.2.2. A model for the information document is given in Annex IIB.

3.2.3. The manufacturer may supplement the application with a report from tests which have been carried out. Any such data provided may be used by the approval authority for the purpose of drawing up the type-approval certificate.

3.2.4. If the technical service responsible for the type-approval test carries out the test itself, then a sample of the ESA system representative of the type to be approved shall be provided, if necessary, after discussion with the manufacturer on, for example, possible variations in the layout, number of components, number of sensors. If the technical service deems it necessary, it may select a further sample.

3.2.5. The sample(s) must be clearly and indelibly marked with the manufacturer's trade name or mark and the type designation.

3.2.6. Where applicable, any restrictions on use should be identified. Any such restrictions should be included in Annexes IIB and/or IIIB.

4. Type-approval

4.1. Routes to type-approval

4.1.1. Type-approval of a vehicle

The following alternative routes to type-approval of a vehicle may be used at the discretion of the vehicle manufacturer.

4.1.1.1. Approval of a vehicle installation

A vehicle installation may achieve type-approval directly by following the provisions laid down in paragraph 6 of this Annex. If this route is chosen by a vehicle manufacturer, no separate testing of electrical/electronic systems or ESAs is required.

4.1.1.2. Approval of vehicle type by testing of individual ESAs

A vehicle manufacturer may obtain approval for the vehicle by demonstrating to the approval authority that all the relevant (see paragraph 3.1.3 of this Annex) electrical/electronic systems or ESAs have individually been approved in accordance with this Directive and have been installed in accordance with any conditions attached thereto.

4.1.1.3. A manufacturer, if he wishes, may obtain approval to this Directive if the vehicle has no equipment of the type which is subject to immunity or emission tests. The vehicle shall have no systems as specified in paragraph 3.1.3 (immunity) and no spark ignition equipment. Such approvals do not require testing.

4.1.2. Type-approval of an ESA

Type-approval may be granted to an ESA to be fitted either to any vehicle type or to a specific vehicle type or types requested by the manufacturer. ESAs involved in the direct control of vehicles will normally receive type-approval in conjunction with a vehicle manufacturer.

4.2. Granting of type-approval

4.2.1. Vehicle

4.2.1.1. If the representative vehicle fulfils the requirements of this Directive, EEC type-approval pursuant to Article 4 (3), and if applicable, Article 4 (4) of Directive 70/156/EEC shall be granted.

4.2.1.2. A model for the EEC type-approval certificate is given in Annex IIIA.

4.2.2. ESA

4.2.2.1. If the representative ESA system(s) fulfil(s) the requirements of this Directive, EEC type-approval pursuant to Article 4 (3), and if applicable, Article 4 (4) of Directive 70/156/EEC shall be granted.

4.2.2.2. A model for the EEC type-approval certificates is given in Annex IIIB.

4.2.3. In order to draw up the certificates referred to in paragraph 4.2.1.2 or 4.2.2.2, the competent authority of the Member State granting the approval may use a report prepared by an approved or recognized laboratory or in accordance with the provisions of this Directive.

4.3. Amendments to approvals

4.3.1. In the case of amendments to approvals granted pursuant to this Directive, the provisions of Article 5 of Directive 70/156/EEC shall apply.

4.3.2. Amendment of a vehicle type-approval by ESA addition or substitution.

4.3.2.1. Where a vehicle manufacturer has obtained approval for a vehicle installation and wishes to fit an additional or substitutional electrical/electronic system or ESA which has already received approval pursuant to this Directive, and which will be installed in accordance with any conditions attached thereto, the vehicle approval may be amended without further testing. The additional or substitutional electrical/electronic system or ESA shall be considered as part of the vehicle for conformity of production purposes.

4.3.2.2. Where the additional or substitutional part(s) has (have) not received approval pursuant to this Directive, and if testing is considered necessary, the whole vehicle shall be deemed to comply if the new or revised part(s) can be shown to comply with the relevant requirements of paragraph 6 or if, in a comparative test, the new part can be shown not to be likely to adversely affect compliance of the vehicle type.

4.3.2.3. The addition by a vehicle manufacturer to an approved vehicle of standard domestic or business equipment, other than mobile communication equipment (*) which complies with Directive 89/336/EEC, and is installed according to the recommendations of the equipment and vehicle manufacturers, or the substitution or removal thereof, shall not invalidate the vehicle approval. This shall not preclude vehicle manufacturers fitting communication equipment with suitable installations guidelines developed by the vehicle manufacturer and/or manufacturer(s) of such communication equipment. The vehicle manufacturer shall provide evidence (if requested by the test authority) that vehicle performance is not adversely affected by such transmitters. This can be a statement that the power levels and installation are such that the immunity levels of this Directive offer sufficient protection when subject to transmission alone, i.e. excluding transmission in conjunction with the tests specified in paragraph 6. This Directive does not authorize the use of a communication transmitter when other requirements on such equipment or its use apply. A vehicle manufacturer may refuse to install in his vehicle standard domestic or business equipment which complies with Directive 89/336/EEC.

5. Marking

5.1. Every ESA conforming to a type approved pursuant to this Directive shall bear an EEC type-approval mark.

5.2. This mark shall consist of a rectangle surrounding the letter 'e' followed by the distinguishing number or letters of the Member State which has granted type-approval:

1 Germany

2 France

3 Italy

4 the Netherlands

6 Belgium

9 Spain

11 the United Kingdom

13 Luxembourg

18 Denmark

21 Portugal

It must also include in the vicinity of the rectangle the four-digit sequential number (with leading zeros as applicable) - hereinafter referred to as 'base approval number' - contained in Section 4 of the type-approval number shown on the EEC type-approval certificate issued for the type of device in question (see Annex IIIB), preceded by the two figures indicating the sequence number assigned to the most recent major technical amendment to Directive 72/245/EEC on the date EEC component type-approval was granted. In this Directive the sequence number is 02.

5.3. The EEC type-approval mark must be affixed to the main part of the ESA (e.g. the electronic control unit) in such a way as to be clearly legible and indelible.

5.4. An example of the EEC type-approval mark is shown in Appendix 7.

5.5. No marking is required for electrical/electronic systems included in vehicle types approved by this Directive.

7. Conformity of production

7.1. Measures to ensure the conformity of production shall be taken in accordance with the provisions laid down in Article 10 of Directive 70/156/EEC.

7.2. Conformity of production with regard to the electromagnetic compatibility of the vehicle or component of separate technical unit shall be checked on the basis of the data contained in the type-approval certificate(s) set out in Annex IIIA and/or IIIB of this Directive as appropriate.

7.3. If the authority is not satisfied with the auditing procedure of the manufacturer, then items 2.4.2 and 2.4.3 of Annex X to Directive 70/156/EEC and paragraphs 7.3.1 and 7.3.2 below shall apply.

7.3.1. If the conformity of a vehicle, component or STU taken from the series is being verified, production shall be deemed to conform to the requirements of this Directive in relation to broadband radiated emissions and narrowband radiated emissions if the levels measured do not exceed by more than 2 dB, (25 %) the reference limits prescribed in paragraphs 6.2.2.1, 6.2.2.2, 6.3.2.1 and 6.3.2.2 (as appropriate).

7.3.2. If the conformity of a vehicle, component or STU taken from the series is being verified, production shall be deemed to conform to the requirements of this Directive in relation to immunity to electromagnetic radiation if the vehicle, component or STU does not exhibit any degradation relating to the direct control of the vehicle which could be observed by the driver or other road user when the vehicle, component or STU is in the state defined in Annex VI, paragraph 4, and subjected to a field strength, expressed in volts/m, up to 80 % of the reference limits prescribed in paragraph 6.4.2.1 of this Annex.

8. Exceptions

8.1. Where a vehicle or electrical/electronic system or ESA does not include an electronic oscillator with an operating frequency greater than 9 kHz, it shall be deemed to comply with paragraph 6.3.2 or 6.6.2 of Annex I and with Annexes V and VIII.

8.2. Vehicles which do not have electrical/electronic systems or ESAs involved in the direct control of the vehicle need not be tested for immunity and shall be deemed to comply with paragraph 6.4 of Annex I and with Annex VI to this Directive.

8.3. ESAs whose functions are not involved in the direct control of the vehicle need not be tested for immunity and shall be deemed to comply with paragraph 6.7 of Annex I and with Annex IX to this Directive.

8.4. Electrostatic discharge

For vehicles fitted with tyres, the vehicle body/chassis can be considered to be an electrically isolated structure. Significant electrostatic forces in relation to the vehicle's external environment only occur at the moment of occupant entry into or exit from the vehicle. As the vehicle is stationary at these moments, no type-approval test for electrostatic discharge is deemed necessary.

8.5. Conducted transients

Since during normal driving, no external electrical connections are made to vehicles, no conducted transients are generated in relation to the external environment. The responsibility of ensuring that equipment can tolerate the conducted transients within a vehicle, e.g. due to load switching and interaction between systems, lies with the manufacturer. No type-approval test for conducted transients is deemed necessary.

ANNEX IV

METHOD OF MEASUREMENT OF RADIATED BROADBAND ELECTROMAGNETIC EMISSIONS FROM VEHICLES

1. General

1.1. The test method described in this Annex shall only be applied to vehicles.

1.2. Measuring apparatus

The measuring equipment shall comply with the requirements of publication No 16-1 (93) of the International Special Committee on Radio Interference (CISPR).

A quasi-peak detector shall be used for the measurement of braodband electromagnetic emissions in this Annex, or if a peak detector is used an appropriate correction factor shall be used depending on the spark pulse rate.

1.3. Test method

This test is intended to measure the broadband emissions generated by spark ignition systems.

Two alternative reference antenna distances are permissible: 10 or 3 m from the vehicle. In either case the requirements of paragraph 3 of this Annex shall be complied with.

2. Expression of results

The results of measurements shall be expressed in dB microvolt/m (microvol/m) for 120 kHz band width. If the actual band width B (expressed in kHz) of the measuring apparatus differs from 120 kHz, the readings taken in microvolts/m shall be converted to 120 kHz band width through multiplication by a factor 120/B.

3. Measuring location

3.1. The test site shall be a level, clear area free from electromagnetic reflecting surfaces within a circle of minimum radius 30 m measured from a point midway between the vehicle and the antenna (see Figure 1 of Appendix 1 to this Annex).

3.2. The measuring set, test hut, or vehicle in which the measurement set is located may be within the test site, but only in the permitted region shown in Figure 1 in Appendix 1 to this Annex.

Other measuring antennae are allowed within the test area, at a minimum distance of 10 m both from receiving antenna and the vehicle under test, provided that it can be shown that the test results will not be affected.

3.3. Enclosed test facilities may be used if correlation can be shown between the enclosed test facility and an outdoor site. Enclosed test facilities do not need to meet the dimensional requirements of Figure 1 in Appendix 1 of this Annex other than the distance from the antenna to the vehicle and the height of the antenna. Neither do they need to have ambient emissions checked before or after the test as indicated in paragraph 3.4 of this Annex.

3.4. Ambient

To ensure that there is no extraneous noise or signal of a magnitude sufficient to affect materially the measurement, measurements shall be taken before and after the main test. If the vehicle is present when ambient measurements are taken, it will be necessary to ensure that any emissions from the vehicle do not affect significantly the ambient measurements, for example by removing the vehicle from the test area, removing the ignition key, or disconnecting the battery. In both of the measurements, the extraneous noise or signal shall be at least 10 dB below the limits of interference given in paragraph 6.2.2.1 or 6.2.2.2 (as appropriate) of Annex I, except for intentional narrowband ambient transmissions.

This reference point shall be at the midpoint of the vehicle's length or at one point along the side of the vehicle chosen by the manufacturer in conjunction with the competent authority after considering the distribution of electronic systems and the layout of any wiring harness.

Such testing may only take place if the physical construction of the chamber permits. The antenna location must be noted in the test report.

5.4.1.4. either:

1,0 ± 0,2 m inside the vehicle, measured from the point of intersection of the vehicle windscreen and bonnet (point C in Appendix 1 to this Annex), or 0,2 ± 0,2 m from the centre line of the foremost axle of the vehicle measured towards the centre of the vehicle (point D in Appendix 2 to this Annex),

whichever results in a reference point closer to the antenna.

5.5. If it is decided to radiate the rear of the vehicle, the reference point shall be established as in paragraph 5.4. The vehicle shall then be installed facing away from the antenna and positioned as if it had been horizontally rotated 180° around its centre point, i.e. such that the distance from the antenna to the nearest part of the outer body of the vehicle remains the same.

The TEM (transverse electromagnetic mode) cell generates homogeneous fields between the internal conductor (septum) and housing (ground plane). It is used for testing ESAs (see Figure 1 of Appendix 3 to this Annex)).

9.2. Field strength measurement in a TEM cell

9.2.1. The electric field in the TEM cell shall be determined by using the equation:

>START OF GRAPHIC>

|E| = √(P × Z) d>END OF GRAPHIC>

E = Electric field (volts/metre)

P = Power flowing into cell (W)

Z = Impedance of cell (50 `)

d = Separation distance (metres) between the upper wall and the plate (septum).

9.2.2. Alternatively an appropriate field strength sensor shall be placed in the upper half of the TEM cell. In this part of the TEM cell the electronic control unit(s) has only a small influence on the test field. The output of this sensor shall determine the field strength.

10. Bulk current injection testing

10.1. Test method

This is a method of carrying out immunity tests by inducing currents directly into a wiring harness using a current injection probe. The injection probe consists of a coupling clamp through which the cables of the ESA under test are passed. Immunity tests can then be carried out by varying the frequency of the induced signals.

The ESA under test may be installed on a ground plane as in paragraph 8.2.1 or in a vehicle in accordance with the vehicle design specification.

10.2. Calibration of bulk current injection probe prior to commencing tests

The injection probe shall be mounted in a calibration jig. Whilst sweeping the test frequency range, the power required to achieve the current specified in Annex I, paragraph 6.7.2.1 shall be monitored. This method calibrates the bulk current injection system forward power versus current prior to testing, and it is this forward power which shall be applied to the injection probe when connected to the ESA under test via the cables used during calibration. It should be noted that the monitored power applied to the injection probe is the forward power.

10.3. Installation of the ESA under test

For an ESA mounted on a ground plane as in paragraph 8.2.1 all cables in the wiring harness should be terminated as realistically as possible and preferably with real loads and actuators. For both vehicle mounted and ground plane mounted ESAs the current injection probe shall be mounted in turn around all the wires in the wiring harness to each connector and 150 ± 10mm from each connector of the ESA under test electronic control units (ECU), instrument modules or active sensors as illustrated in Figure 1 of Appendix 2.

10.4. Power, signal and control wires

For an ESA under test mounted on a ground plane as in paragraph 8.2.1, a wiring harness shall be connected between an artificial network (AN) and the principal electronic control unit (ECU). This harness shall run parallel to the edge of the ground plane and 200 mm minimum from its edge. This harness shall contain the power feed wire which is used to connect the vehicle battery to this ECU and the power return wire if used on the vehicle.

The distance from the ECU to the AN shall be 1,0 ± 0,1 m or shall be the harness length between the ECU and the battery as used on the vehicle, if known, whichever is the shorter. If a vehicle harness is used then any line branches which occur in this length shall be routed along the ground plane but perpendicular away from the edge of the ground plane. Otherwise the ESA under test wires which are in this length shall break out at the AN.
