B.   TECHNICAL REQUIREMENTS FOR HEADLAMPS (5)

5

5.   GENERAL SPECIFICATIONS

5.1.   Each sample shall comply with the specifications set forth in paragraphs 6 to 8 below.

5.2.   Headlamps shall be so made as to retain their prescribed photometric characteristics and to remain in good working order when in normal use, in spite of the vibrations to which they may be subjected.

5.2.1.   Headlamps shall be fitted with a device enabling them to be so adjusted on the vehicle as to comply with the rules applicable to them. Such a device need not be fitted on units in which the reflector and the diffusing lens cannot be separated, provided the use of such units is confined to vehicles on which the headlamps setting can be adjusted by other means.

Where a headlamp providing a principal passing beam and a headlamp providing a driving beam, each equipped with its own light source(s), are assembled to form a composite unit, the adjusting device shall enable each optical system individually to be duly adjusted. The same provision applies to headlamps providing a front fog lamp beam and a driving beam, and to headlamps providing a principal passing beam and a front fog lamp beam, and to headlamps providing these three beams.

5.2.2.   However, these provisions shall not apply to headlamp assemblies whose reflectors are indivisible. For this type of assembly, the requirements of paragraph 6.3 of this Regulation shall apply.

5.3.   Headlamps designed to satisfy the requirements of both right-hand and of left-hand traffic may be adapted for traffic on a given side of the road either by an appropriate initial setting when fitted on the vehicle or by selective setting by the user. Such initial or selective setting may consist, for example, of fixing either the optical unit at a given angle on the vehicle or the light source(s) at a given angle in relation to the optical unit. In all cases, only two different and clearly distinct settings, one for right-hand and one for left-hand traffic, shall be possible, and the design shall preclude inadvertent shifting from one setting to the other or setting in an intermediate position. Where two different setting positions are provided for the light source, the components for attaching the light source to the reflector must be so designed and made that, in each of its two settings, the light source will be held in position with the precision required for headlamps designed for traffic on only one side of the road. Conformity with the requirements of this paragraph shall be verified by visual inspection and, where necessary, by a test fitting.

5.4.   Illumination configuration for different traffic conditions

5.4.1.   In the case of headlamps designed to meet the requirements of traffic moving on one side of the road (either right or left) only, appropriate measures shall be taken to prevent discomfort to road-users in a country where traffic moves on the side of the road opposite to that of the country for which the headlamp was designed (6).

Method of measurement of the diffusion and transmission of light

1.   EQUIPMENT (SEE FIGURE)

The beam of a collimator K with a half divergence β/2 = 17,4 × 10–4 rd is limited by a diaphragm DT with an opening of 6 mm against which the sample stand is placed.

A convergent achromatic lens L2, corrected for spherical aberrations, links the diaphragm DT with the receiver R; the diameter of the lens L2 shall be such that it does not diaphragm the light diffused by the sample in a cone with a half top angle of β/2 = 14°.

An annular diaphragm DD with angles α/2 = 1° and αmax/2 = 12° is placed in an image focal plane of the lens L2.

The non-transparent central part of the diaphragm is necessary in order to eliminate the light arriving directly from the light source. It shall be possible to remove the central part of the diaphragm from the light beam in such a manner that it returns exactly to its original position.

The distance L2 DT and the focal length F2
   (1) of the lens L2 shall be so chosen that the image of DT completely covers the receiver R.

When the initial incident flux is referred to 1 000 units, the absolute precision of each reading shall be better than 1 unit.

2.   MEASUREMENTS

The following readings shall be taken:

| Reading | With sample | With central part of DD | Quantity represented |
| --- | --- | --- | --- |
| T1 | no | no | Incident flux in initial reading |
| T2 | yes
  (before test) | no | Flux transmitted by the new material in a field of 24° |
| T3 | yes
  (after test) | no | Flux transmitted by the tested material in a field of 24° |
| T4 | yes
  (before test) | yes | Flux diffused by the new material |

Moving upward from below the line B (see figure 2 below), a vertical scan is carried out through the horizontal part of the ‘cut-off’ at 2,5° from V-V. The inflection point (where d2 (log E)/dv2 = 0) is determined and positioned on the line B situated one per cent below H-H.

3.2.   Horizontal adjustment

The applicant shall specify one of the following horizontal aim methods:

| (a) | The ‘0,2 D line’ method (see figure 2 below).
  A single horizontal line at 0,2° D shall be scanned from 5° left to 5° right after the lamp has been aimed vertically. The maximum gradient ‘G’ determined using the formula

  where β is the horizontal position in degrees, shall not be less than 0,08.
  The inflection point found on the 0,2 D line shall be positioned on the line A.
