COMMISSION DIRECTIVE of 22 November 1979 adapting to technical progress Council Directive 74/347/EEC on the approximation of the laws of the Member States relating to the field of vision and windscreen wipers of wheeled agricultural or forestry tractors (79/1073/EEC)

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Economic Community,

Having regard to Council Directive 74/150/EEC of 4 March 1974 on the approximation of the laws of the Member States relating to the type-approval of wheeled agricultural or forestry tractors (1), as last amended by Directive 79/694/EEC (2), and in particular Articles 11, 12 and 13 thereof,

Having regard to Council Directive 74/347/EEC of 25 June 1974 on the approximation of the laws of the Member States relating to the field of vision and windscreen wipers of wheeled agricultural or forestry tractors (3),

Whereas, in view of experience gained and the provisions adopted concerning roll-over protection structures which affect the configuration of those parts of the tractor superstructure which are of great importance for the field of vision, it is now possible to adapt to technical progress the provisions relating to the field of vision;

Whereas traffic safety requirements in respect of wheeled agricultural or forestry tractors have become more stringent;

ANNEX

1.4 to read as follows:

Masking effect

"Masking effect" means the chords of the sectors of the semi-circle of vision which cannot be seen owing to structural components such as roof-pillars, air intakes or exhaust stacks and the frame of the windscreen.

2.2.1.1 to read as follows:

The tractor must be placed on a horizontal surface as shown in Figure 2. On a horizontal support level with the reference point, there must be mounted two point sources of light, e.g. 2 × 150 W, 12 V, 65 mm apart and symmetrically located with respect to the reference point. The support must be rotatable at its centre point about a vertical axis passing through the reference point. For the purpose of measuring the masking effects, the support must be so aligned that the line joining the two light sources is perpendicular to the line joining the masking component and the reference point.

The silhouette (deepest shadow) overlaps projected on to the semi-circle of vision by the masking component when the light sources are switched on simultaneously or alternately must be measured in accordance with 1.4 (Figure 3).

2.2.1.2 to read as follows:

Masking effects must not exceed 700 mm.

2.2.1.3 to read as follows:

Masking effects due to adjacent structural components over 80 mm in width must be so configured that there is an interval of not less than 2 200 mm - measured as a chord of the semi-circle of vision - between the centres of two masking effects.

2.2.1.5 to read as follows:

Outside the sector of vision, masking effects exceeding 700 mm but not exceeding 1 500 mm are, however, permissible if the components causing them cannot be redesigned or relocated : on each side there may be a total of either two such masking effects, one not exceeding 700 mm and the other not exceeding 1 500 mm, or two such masking effects, neither exceeding 1 200 mm.

2.2.2.1 to read as follow:

As an alternative to the procedure set out in 2.2.1, the acceptability of individual masking effects can be determined mathematically. The requirements of 2.2.1.2, 2.2.1.3, 2.2.1.4, 2.2.1.5 and 2.2.1.6 shall apply in respect of the size, distribution and number of the masking effects.

2.5 to read as follows:

For the purpose of determining the masking effects in the sector of vision, the masking effects due to the frame of the windscreen and to any other obstacle may, in accordance with the provisions of 2.2.1.4, be considered as a single effect, provided that the distance between the outermost points of this masking effect does not exceed 700 mm.
