(1)  In the case of headlamps designed to meet the requirements of traffic moving on one side of the road only (either right or left), it is further recommended that the area which can be occulted to prevent discomfort to 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 should be outlined indelibly on the front glass. This marking is not necessary, however, where the area is clearly apparent from the design.

1

(2)  If the lens cannot be detached from the main body of the headlamp, a space on the lens shall be sufficient.

2

(3)  A change in the colour of the beams emitted by headlamps whose other characteristics are not changed does not constitute a change of headlamp type. The same approval number shall accordingly be assigned to such headlamps (see paragraph 2.3).

3

(4)  If different types of headlamps have an identical lens, the lens may bear the several approval marks of these type of headlamps, on condition that the main body of the headlamp, even if it cannot be separated from the lens, is also provided with the space referred to in paragraph 4.2 above and bears the approval mark of the type of headlamp. If different types of headlamps have an identical main body, it may bear the several approval marks for these types of headlamps.

(6)  These filters shall consist of all the components, including the lens, intended to colour the light.

6

(7)  The test screen must be sufficiently wide to allow examination of the "cut off" over a range of at least 5° on either side of the line vv.

7

(8)  If the beam does not have a cut off with a clear "apex", the lateral adjustment shall be effected in the manner which best satisfies the requirements for illumination at points 75 R and 50 R for right hand traffic and for points 75 L and 50 L for left hand traffic.

8

(9)  The limit of realignment of l° towards the right or left is not incompatible with upward or downward vertical realignment. The latter is limited only by the requirements of paragraph 7.3. However, the horizontal part of the "cut off" should not extend beyond the line hh.

Formula

3.   CONFORMITY OF PRODUCTION

One of the sampled headlamps shall be tested according to the procedure described in paragraph 2.1 after being subjected three consecutive times to the cycle described in paragraph 2.2.2. The headlamp shall be considered as acceptable if Δr does not exceed 1,5 mrad.

If this value exceeds 1,5 mrad but is not more than 2,0 mrad, a second headlamp shall be subjected to the test after which the mean of the absolute values recorded on both samples shall not exceed 1,5 rad.

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 °C |

6.   STABILITY OF PHOTOMETRIC PROPERTIES

6.1.   The approval granting authority has the right to test the optical properties stability of a retro-reflecting material in use (when used for marking or as distinctive markings/graphics).

6.2.   The Administrative Departments of Contracting Parties, in which the approval was granted, may undertake the same tests. If “systematic failures in use” occur for a type of retro-reflective material, the tested material samples shall be transferred for appraisal to the authority which granted approval.

6.3.   If other criteria are missing, the notation “systematic failures in use” for a type of retro-reflective material is to be established according to paragraph 6 of this Regulation.

7.   RESISTANCE TO PENETRATION OF WATER

7.1.   Sample unit of retro-reflective marking shall be immersed for 10 minutes in water at a temperature of 50 ± 5 °C, the highest point of the upper part of the retro-reflective surface being 20 mm below the surface of the water. This test shall be repeated after turning the sample unit through 180°, so that the retro-reflecting surface is at the bottom and the rear face is covered by about 20 mm of water. The sample unit(s) shall then be immediately immersed in the same conditions in water at a temperature of 25 ± 5 °C.

7.2.   No water must penetrate to the reflecting surface of the sample unit. If visual inspection clearly reveals the presence of water, the retro-reflective marking shall not be considered to have passed the test.

7.3.   If visual inspection does not reveal the presence of water or in case of doubt, the coefficient of retro-reflection R' shall be measured in conformity with Annex 7, the sample unit being first lightly shaken to remove excess water from the outside.
