as a percentage of the minimum intensities required in the table in paragraph 6.1.:

       2.1.1. in the direction H = 0 degrees  and V = 0 degrees  for categories 1, 1a, 1b, 2a, 2b, 3 and in the case of category 4 to the front only;

       2.1.2. in the direction H = 5 degrees  and V = 0 degrees  for category 6.

       2.2. Within the field of light distribution of paragraph 2., schematically shown as a grid, the light pattern should be substantially uniform, i.e. in so far as the light intensity in each direction of a part of the field formed by the grid lines shall meet at least the lowest minimum value being shown on the grid lines surrounding the questioned direction as a percentage.

       3. Photometric measurement of lamps equipped with several light sources

       The photometric performance shall be checked:

       3.1. For non-replaceable light sources (filament lamps and other):

       with the light sources present in the lamp, in accordance with paragraph 7.1.1 of this Regulation.

       3.2. For replaceable filament lamps:

       when equipped with mass production filament lamps at 6.75 V, 13.5 V or 28.0 V, the luminous intensity values produced shall lie between the maximum limit given in this Regulation and the minimum limit of this Regulation increased according to the permissible deviation of the luminous flux permitted for the type of filament lamp chosen, as stated in Regulation No. 37 for production of filament lamps; alliteratively a standard filament lamp may be used in turn, in each of the individual positions, operated at its reference flux, the individual measurements in each position being added together.

       Annex 5

       COLOUR- OF AMBER LIGHTS:

       TRICHROMATIC CO-ORDINATES

       Limit towards yellow: y<0.429

       Limit towards red: y>0.398

       Limit towards white: z<0.007

For checking these colorimetric characteristics, a source of light at a colour temperature of 2,856 K corresponding to illuminant A of the International Commission on Illumination (CIE) shall be used in conformity with the Convention on Road Traffic (E/ CONF.56/16/Rev.1).

However, for lamps equipped with non-replaceable light sources (filament lamps and other), the colorimetric characteristics should be verified with the light sources present in the lamp, in accordance with paragraph 7.1.1 of this Regulation.

       Annex 6

       MINIMUM REQUIREMENTS FOR CONFORMITY OF PRODUCTION CONTROL PROCEDURES

       1. GENERAL

       1.1. The conformity requirements shall be considered satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation.

       1.2. With respect to photometric performances, the conformity of mass-produced direction indicators shall not be contested if, when testing photometric performances of any direction indicator chosen at random and equipped with a standard filament lamp, or when the direction indicators are equipped with non-replaceable light sources
