1.1.2.   Test results

1.1.2.1.   Visual inspection

Once the headlamp has been stabilized to the ambient temperature, the headlamp lens and the external lens, if any, shall be cleaned with a clean, damp cotton cloth. It shall then be inspected visually; no distortion, deformation, cracking or change in colour of either the headlamp lens or the external lens, if any, shall be noticeable.

To comply with the requirements of this Regulation, the photometric values shall be verified in the following points:

Another aiming may be carried out to allow for any deformation of the headlamp base due to heat (the change of the position of the ‘cut-off’ line is covered in paragraph 2 of this Annex).

Except for points 0,50 U/1,5 L and 0,50 U/1,5 R, a 10 per cent discrepancy between the photometric characteristics and the values measured prior to the test is permissible including the tolerances of the photometric procedure. The value measured at points 0,50 U/1,5 L and 0,50 U/1,5 R shall not exceed the photometric value measured prior to the test by more than 255 cd.

1.2.   Dirty headlamp

1.2.1.2.   Application of the test mixture to the headlamp

The test mixture shall be uniformly applied to the entire light-emitting surface of the headlamp and then left to dry.

This procedure shall be repeated until the illumination value has dropped to 15-20 per cent of the values measured for each of the following points under the conditions described in this Annex:

2.   TEST FOR CHANGE IN VERTICAL POSITION OF THE ‘CUT-OFF’ LINE UNDER THE INFLUENCE OF HEAT

This test consists of verifying that the vertical drift of the ‘cut-off’ line under the influence of heat does not exceed a specified value for an operating headlamp producing a passing beam.

The headlamp tested in accordance with paragraph 1, shall be subjected to the test described in paragraph 2.1, without being removed from or readjusted in relation to its test fixture.

2.1.   Test

The test shall be carried out in a dry and still atmosphere at an ambient temperature of 23 °C ± 5 °C.

Using a mass production filament lamp(s) which has been aged for at least one hour or a mass production gas-discharge light source which has been aged for at least 15 hours or the LED module(s) as submitted with the headlamps, which has (have) been aged for at least 48 hours, the headlamp shall be operated on passing beam without being dismounted from or readjusted in relation to its test fixture. (For the purpose of this test, the voltage shall be adjusted as specified in paragraph 1.1.1.2). The position of the ‘cut-off’ line in its horizontal part (between the vertical lines passing through point 50 L and 50 R for Class B headlamp, 3,5 L and 3,5 R for Classes C, D and E headlamp) shall be verified 3 minutes (r3) and 60 minutes (r60) respectively after operation.

(1)  For the test schedule see Annex 8 to this Regulation.

(2)  When the tested headlamp includes signalling lamps, the latter shall be lit for the duration of the test. In the case of a direction indicator lamp, it shall be lit in flashing mode with an on/off time of approximately one to one.

(3)  Should two or more lamp light source be simultaneously lit when headlamp flashing is used, this shall not be considered as being normal use of the light source simultaneously.

(4)  NaCMC represents the sodium salt of carboxymethylcellulose, customarily referred to as CMC. The NaCMC used in the dirt mixture shall have a degree of substitution (DS) of 0,6-0,7 and a viscosity of 0,2-0,3 Pa · s for a 2 per cent solution at 20 °C.

(5)  The tolerance on quantity is due to the necessity of obtaining a dirt that correctly spreads out on all the plastic lens.

DEFINITION AND SHARPNESS OF THE ‘CUT-OFF’ LINE FOR SYMMETRICAL PASSING BEAM HEADLAMPS AND AIMING PROCEDURE BY MEANS OF THIS ‘CUT-OFF’ LINE

1.   GENERAL

2.   SHAPE OF THE ‘CUT-OFF’ LINE

2.1.

For visual adjustment of the symmetrical passing-beam headlamp the ‘cut-off’ line shall provide a horizontal line for vertical adjustment of the symmetrical passing-beam headlamp extending to either side of the V-V line (see Figure 1) as specified in paragraph 6.2.1 of this Regulation. Figure 1 Shape and position of the ‘cut-off’ line

3.   ADJUSTMENT OF THE SYMMETRICAL PASSING-BEAM HEADLAMP

4.   MEASUREMENT OF THE QUALITY OF ‘CUT-OFF’

4.1.

Measurements shall be performed by vertically scanning through the horizontal part of the ‘cut-off’ line in angular steps not exceeding 0,05°: (a) At either a measurement distance of 10 m and a detector with a diameter of approximately 10 mm; (b) Or at a measurement distance of 25 m and a detector with a diameter of approximately 30 mm. The measurement of the ‘cut-off’ quality shall be considered acceptable if the requirements of the paragraph 4.1.2 of this Annex shall comply with at least one measurement at 10 m or 25 m. The measuring distance at which the test was determined shall be noted down in paragraph 9, Annex 1 ‘Communication form’ of this Regulation. The scanning is performed from its lower position upwards through the ‘cut-off’ line along the vertical lines at - 3° to - 1,5° and + 1,5° to + 3° from the V-V line. When so measured, the quality of the ‘cut-off’ line shall meet the following requirements: 4.1.1. Not more than one ‘cut-off’ line shall be visible (1). 4.1.2. Sharpness of ‘cut-off’: if scanned vertically through the horizontal part of the ‘cut-off’ line along the ± 2,5 lines, the maximum value measured for: is called the sharpness factor G of the ‘cut-off’ line. The value of G shall not be less than 0,13 for Class B and 0,08 for Classes A, C, D and E. 4.1.3. Linearity: the part of the ‘cut-off’ line which serves for vertical adjustment shall be horizontal from 3°L to 3°R of the V-V line. This requirement is deemed to be met if the vertical positions of the inflection points according to paragraph 3.2 above at 3° left and right of the V-V line do not differ by more than 0,2° for Class B and 0,3° for Classes A, C, D and E headlamps from the nominal position at the V-V line.

5.   INSTRUMENTAL VERTICAL ADJUSTMENT

If the ‘cut-off’ line complies with the above quality requirements, the vertical beam adjustment can be performed instrumentally. For this purpose the inflection point where d2 (log E)/dv2 = 0 is positioned on the V-V line in its nominal position below the h-h-line. The movement for measuring and adjusting the ‘cut-off’ line shall be upwards from below the nominal position.

(1)  This paragraph will be amended, if an objective test method is available.

The above drawing represents the mark of the centre of reference as projected on a plane substantially tangent to the lens about the centre of the circle. The lines constituting this mark may either be solid or dotted.
