A4  Annex 4 a0c0
A4  Photometric measurements a0c0
A4 1. Measurement methods a0c0
A4 1.1. During photometric measurements, stray reflections shall be prevented by appropriate masking. a0c0
A4 1.2. Should the results of measurements be challenged, measurements shall be carried out in such a way as to meet the following requirements: a0c0
A4 1.2.1. The distance of measurements shall be such that the law of the inverse of the square of the distance is applicable; a0c0
A4 1.2.2.

The measuring equipment shall be such that the angular aperture of the receiver viewed from the reference centre of the lamp is between 10' and 1°;

 a0c0
A4 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. a0c0
A4 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 the reference axis specified by the manufacturer. a0c0
A4 2. Standard luminous intensity distribution table a0c0
A4  a0c0
A4 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°).

 a0c0
A4 2.2. Within the field of light distribution of paragraph 2., schematically shown as a grid, the light pattern should be substantially uniform so that 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 on the grid lines surrounding the questioned direction. a0c0
A4 2.3. However, in the case where a device is intended to be installed at a mounting height of equal to or less than 750 mm above the ground, the photometric intensity is verified only up to an angle of 5 degrees downwards. a1c0
A4 3. Test conditions a0c0
A4  The photometric performance shall be checked: a0c0
A4 3.1. For non-replaceable light sources (filament lamps and others): a0c0
A4  With the light sources present in the lamp, in accordance with the relevant subparagraph of paragraph 8.1. of this Regulation. a0c0
A4 3.2. For replaceable light sources: a0c0
A4 

When equipped with light sources at 6.75 V or 13.5 V, the luminous intensity values produced shall be corrected.

 a0c0
A4 

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 (6.75 V or 13.5 V).

 a0c0
A4 

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 (6.75 V or 13.5 V).

 a0c0
A4 

The actual luminous fluxes of each light source used shall not deviate more than ±5 per cent from the mean value.

 a0c0
A4  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 3.3.

For any signalling lamps, except those equipped with filament lamps, the luminous intensities measured after one minute and after 30 minutes of operation shall comply with the minimum and maximum requirements; direction indicators shall be operated in the flashing mode (f =±1.5 Hz, duty factor 50 per cent). The luminous intensity distribution after one minute of operation can be calculated from the luminous intensity distribution after 30 minutes of operation by applying at each test point the ratio of luminous intensities measured at HV after one minute and after 30 minutes of operation.

 a0c0
A5  Annex 5 a0c0
A5  Photometric measurements for the rear-registration-plate illuminating device a0c0
A5 1. Space to be illuminated a0c0
A5  The devices can be of category 1 or 2. The devices of category 1 shall be designed to illuminate a space of at least 130 x 240 mm, the devices of category 2 shall be designed to illuminate a space of at least 200 x 280 mm. a0c0
A5 2. Colour of the light a0c0
A5  The light of the illuminating device shall be sufficiently colourless in order not to modify noticeably the colour of the rear-registration-plate. a0c0
A5 3. Angle of incidence a0c0
A5 

The manufacturer of the illuminating device shall specify one or more or a field of positions in which the device is to be fitted in relation to the space for the registration plate; when the lamp is placed in the position(s) specified by the manufacturer the angle of incidence of the light on the surface of the plate does not exceed 82° at any point of the surface to be illuminated, this angle being measured from the mid-point of the edge of the illuminating surface of the device which is furthest from the surface of the plate. If there is more than one illuminating device, the foregoing requirement shall apply only to the part of the plate intended to be illuminated by the device concerned.

 a0c0
A5  The device shall be so designed that no light is emitted directly towards the rear, with the exception of red light if the device is combined or grouped with a rear lamp. a0c0
A5 4. Measuring procedure a0c0
A5  Luminance measurements shall be made on a diffuse colourless surface with known diffuse reflection factor[1]. The diffuse colourless surface shall have the dimensions of the registration plate or the dimension exceeding one measuring point. Its centre shall be placed in the centre of the positions of the measuring points. a0c0
A5  This diffuse colourless surface(s) shall be placed in the position normally occupied by the registration plate and 2 mm in front of its holder. a0c0
A5 

Luminance measurements shall be made perpendicularly to the surface of the diffuse colourless surface with the tolerance of 5° in each direction at the points shown in paragraph 5. of this annex, each point representing a circular area of 25 mm in diameter.

 a0c0
A5  The measured luminance shall be corrected for the diffuse reflection factor 1.0. a0c0
A5  For an illuminating device not equipped with filament lamps, the luminance values measured after one minute and after 30 minutes of operation shall comply with the minimum requirements. The luminance distribution after one minute of operation can be calculated from the luminance distribution after 30 minutes of operation, by applying at each test point the ratio of luminance values measured at one point after one minute and after 30 minutes of operation. a0c0
A5 [1] CIE Publication No. 17 - 1970, paragraph 45-20-040 a0c0
A5 5. Photometric characteristics a0c0
A5  At each of the points of measurement shown below, the luminance B shall be not less than 2 cd/m2. a0c0
A5  a0c0
A5  The gradient of the luminance between the values B1 and B2, measured at any two points 1 and 2 selected from among those mentioned above, shall not exceed 2 x B0/cm, B0 being the minimum luminance measured at the various points, that is to say: a0c0
