A3  Annex 3 a0c0
A3  Photometric measurements a0c0
A3 1. Measurement methods general a0c0
A3 1.1. When photometric measurements are taken, stray reflections shall be avoided by appropriate masking. a0c0
A3 1.2. In the event that the results of measurements are challenged, measurements shall be taken in such a way as to meet the following requirements: a0c0
A3 1.2.1. The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable; a0c0
A3 1.2.2.

The measuring equipment shall be such that the angle subtended by the receiver from the reference centre of the light is between 10' and 1°;

 a0c0
A3 1.2.3. The intensity requirement for a particular direction of observation shall be satisfied if the required intensity is obtained in a direction deviating by not more than one quarter of a degree from the direction of observation. a0c0
A3 1.3. In the case where the device may be installed on the vehicle in more than one or in a field of different positions the photometric measurements shall be repeated for each position or for the extreme positions in the field of reference axis specified by the manufacturer. a0c0
A3 2. For reversing lamps the measuring points expressed in degrees of angle with the axis of reference and values of the minimum intensities of the light emitted. a0c0
A3  a0c0
A3 2.1.

The directions H = O° and V = O° correspond to the axis of reference. On the vehicle they are horizontal, parallel to the median longitudinal plane of the vehicle and oriented in the required direction of visibility. They pass through the centre of reference. The values shown in the table give, for the various directions of measurement, the minimum intensities in cd.

 a0c0
A3 2.2.

If visual examination of a lamp appears to reveal substantial local variations of intensity, a check shall be made to ensure that no intensity measured between two of the directions of measurement referred to above is below 50 per cent of the lower minimum intensity of the two prescribed for these directions of measurement.

 a0c0
A3 3. Photometric measurement of lamps equipped with several light sources a0c0
A3  The photometric performance shall be checked: a0c0
A3 3.1. For non-replaceable light sources (filament lamps and other): a0c0
A3 

With the light sources present in the lamp, in accordance with relevant subparagraphs of paragraph 7.1. of this Regulation.

 a0c0
A3 3.2. For replaceable light source(s): a0c0
A3 

When equipped with light source(s) at 6.75 V, 13.5 V or 28.0 V, the luminous intensity values produced shall be corrected. For filament lamps the correction factor is the ratio between the reference luminous flux and the mean value of the luminous flux found at the voltage applied (6.75V, 13.5V or 28.0V).

 a0c0
A3 

For LED light sources the correction factor is the ratio between the objective luminous flux and the mean value of the luminous flux found at the voltage applied (6.75V, 13.5V or 28.0V).

 a0c0
A3 

The actual luminous fluxes of each filament lamp and/or LED light source used shall not deviate more than 5 per cent from the mean value.

 a0c0
A3  Alternatively and in case of filament lamps only, 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. a0c0
A4  Annex 4 a0c0
