ANNEX 4

Photometric measurements

1. MEASUREMENT METHODS

1.1. During photometric measurements, stray reflections shall be prevented by appropriate masking.

1.2. Should the results of measurements be challenged, measurements shall be carried out in such a way as to meet the following requirements:

1.2.1. the distance of measurements shall be such that the law of the inverse of the square of the distance is applicable;

1.2.2. the measuring equipment shall be such that the angular aperture of the receiver viewed from the reference centre of the light is between 10° and 1°;

1.2.3. the intensity requirement for a particular direction of observation shall be deemed to be satisfied if that requirement is met in a direction deviating by not more than 15° from the direction of observation.

2. STANDARD LUMINOUS INTENSITY DISTRIBUTION TABLE

>PIC FILE= "L_2001131EN.017602.EPS">

2.1. The direction H = 0° and V = 0° corresponds to the reference axis. (On the vehicle it is horizontal, parallel to the median longitudinal plane of the vehicle and oriented in the required direction of visibility). It passes through the centre of reference. The values shown in the table give, for the various directions of measurements, the minimum intensities as a percentage of the minimum required in the axis for each lamp (in the direction H = 0° and V = 0°).

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

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 8.1 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 filament lamps; alternatively 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
