 a0c0
7.1.2. In the case of a lamp equipped with non-replaceable light sources (filament lamps and other), at 6.75 V, 13.5 V or 28.0 V respectively. a0c0
7.1.3.

In the case of a system that uses an electronic light source control gear or a variable intensity control, being part of the lamp[4] applying at the input terminals of the lamp the voltage declared by the manufacturer or, if not indicated, 6.75 V, 13.5 V or 28.0 V respectively.

 a0c0
[4] For the purpose of this Regulation "being part of the lamp" means to be physically included in the lamp body or to be external, separated or not, from the lamp body but supplied by the lamp manufacturer as part of the lamp system. a0c0
7.1.4. In the case of a system that uses an electronic light source control gear or a variable intensity control, not being part of the lamp the voltage declared by the manufacturer shall be applied to the input terminals of the lamp. a0c0
7.2. The test laboratory shall require from the manufacturer the light source control gear or a variable intensity control needed to supply the light source and the applicable functions. a0c0
7.3.

However in the case of a rear fog lamp of category F2 operated by a variable intensity control to obtain variable luminous intensity, photometric measurements shall be performed according to the applicant's description.

 a0c0
7.4.

The voltage to be applied to the lamp shall be noted in the communication for in Annex 1 of this Regulation.

 a0c0
7.5. For any lamp 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. 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
7.6. The limits of the apparent surface in the direction of the reference axis of a light- signalling device shall be determined. a0c0
8. Heat resistance test a0c0
8.1.

The lamp must be subjected to a one-hour test of continuous operation following a warm-up period of 20 minutes. The ambient temperature shall be 23 °C ± 5 °C. The lamp used shall be a lamp of the category prescribed for the lamp, and shall be supplied with a current at a voltage such that it gives the specified average power at the corresponding test voltage.

 a0c0
8.2.

Where only the maximum power is specified, the test shall be carried out by regulating the voltage to obtain a power equal to 90 per cent of the specified power. The specified average or maximum power referred to above shall in all cases be chosen from the voltage range of 6, 12 or 24 V at which it reaches the highest value.

 a0c0
8.3. In the case of light sources operated by an electronic control gear to obtain variable luminous intensity, the test shall be carried out under the conditions given at minimum 90 per cent of the higher luminous intensity. a0c0
8.4 After the lamp has been stabilized at the ambient temperature, no distortion, deformation, cracking or colour modification shall be perceptible. a0c0
9. Colour of light emitted a0c0
...

The colour of the light emitted inside the field of the light distribution grid defined at paragraph 3. of Annex 3, which shall be measured under conditions described in paragraph  7. above, shall be red. Outside this field no sharp variation of colour shall be observed.

 a0c0
... These requirements shall also apply within the range of variable luminous intensity produced by rear fog lamps of category F2. a0c0
...

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 relevant sub-paragraph of paragraph 7.1. of this Regulation.

 a0c0
10. Conformity of production a0c0
...

10.2. The Type Approval Authority which has granted type approval may at any time verify the conformity control methods applied in each production facility. The normal frequency of these verifications shall be once every two years. a2c0
10.3. In the case of non-replaceable filament lamp(s) or light source module(s) equipped with non-replaceable filament lamps, a report (by the light source manufacturer indicated in the type approval documentation) shall demonstrate compliance of these non-replaceable filament lamp(s) with lifetime requirements and, in the case of colour coated filament lamps, also with colour endurance requirements, as specified in paragraph 4.11. of IEC 60809, Edition 3. a2c0
11. Penalties for non-conformity of production a0c0
11.1.

The approval granted for a type of rear fog lamp may be withdrawn if the foregoing requirements are not complied with or if a rear fog lamp bearing the mark referred to in paragraphs 4.3.1. and 4.3.2. does not conform to the type approved.

 a0c0
11.2.

If a Contracting Party to the Agreement which applies this Regulation withdraws an approval it has previously granted, it shall forthwith notify the other Contracting Parties which apply this Regulation by means of a communication form conforming to the model in Annex 1 to this Regulation.

 a0c0
12. Production definitively discontinued a0c0
...

A3 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 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 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 4.

If visual examination of a light appears to reveal substantial local variations of intensity, a check shall be made to ensure that, outside the axes, no intensity measured within the rhombus defined by the extreme directions of measurement is below 75 cd (see diagram below).

 a0c0

 a0c0
A3 5.2. For replaceable light source(s): a0c0
A3 

When equipped with light source(s) at 6.75V, 13.5V or 28.0V, 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). When equipped with LED light source(s) at 6.75V, 13.5V or 28.0V; the luminous flux value produced shall be corrected. The correction factor is the ratio between the objective luminous flux and the value of the luminous flux found at the voltage applied.

 a0c0
A3 

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
