(b) in the case where a test sample provides more than one function or class of passing beam according to this Regulation: if the applicant declares that each specified function or class of passing beam of the test sample has its own light source(s), being exclusively lit ( 7 ) at a time, the test shall be carried out in accordance with this condition, activating (6) the most power consuming mode of each specified function or class of passing beam successively for the same (equally divided) part of the time specified in paragraph 1.1.

In all other cases (6) (7) , the test sample shall be subjected to the following cycle test for each, the mode(s) of class C passing beam, the class V passing beam, the class E passing beam and the class W passing beam, whatever is provided or partly provided by the test sample, for the same (equally divided) part of the time specified in paragraph 1.1.:

15 minutes, first, e.g. class C passing beam mode lit with its most power-consuming mode for straight road conditions;

5 minutes, same passing beam mode lit as before and, additionally, all light sources ( 8 ) of the test sample, which are possible to be lit at the same time, according to the applicants declaration;

after having reached the said (equally divided) part of the time specified in paragraph 1.1., the above cycle test shall be performed with the second, third and fourth class of passing beam, if applicable, in the above order.

The voltage shall be adjusted so as to supply 90 per cent of the maximum wattage specified in Regulation No 37 for the filament light source(s) used. The applied wattage shall in all cases comply with the corresponding value of a filament light source of 12 V rated voltage, except if the applicant specifies that the test sample may be used at a different voltage. In this case, the test shall be carried out with the filament light source whose wattage is the highest that can be used.

(b) In case of replaceable gas discharge light source(s): The test voltage for the electronic light source control-gear is 13,5 ± 0,1 volts for 12 V vehicle voltage system, or otherwise specified in the application for approval.

METHOD OF MEASUREMENT OF THE DIFFUSION AND TRANSMISSION OF LIGHT

1. EQUIPMENT (see Figure 1 below)

The beam of a collimator K with a half divergence β/2 = 17,4 × 10–4 rad is limited by a diaphragm Dτ 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 Dτ 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 deg.

An annular diaphragm DD, with angles α0/2 = 1 deg and αmax/2 = 12 deg 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 Dτ and the focal length F2 of the lens L2 shall be so chosen that the image of Dτ completely covers the receiver R.

For L2 it is recommended to use a focal distance of about 80 mm.

When the initial incident flux is referred to 1 the absolute precision of each reading shall be better than 0,001 .

SPRAY TESTING METHOD

1. TEST EQUIPMENT

1.1. Spray gun

The spray gun used shall be equipped with a nozzle 1,3 mm in diameter allowing a liquid flow rate of 0,24 ± 0,02 l/minute at an operating pressure of 6,0 bars 0 /0,5 bar.

Under these operation conditions the fan pattern obtained shall be 170 mm ± 50 mm in diameter on the surface exposed to deterioration, at a distance of 380 mm ± 10 mm from the nozzle.

1.2. Test mixture

The test mixture shall be composed of:

Silica sand of hardness 7 on the Mohr scale, with a grain size between 0 and 0,2 mm and an almost normal distribution, with an angular factor of 1,8 to 2;

Water of hardness not exceeding 205 g/m3 for a mixture comprising 25 g of sand per litre of water.

2. TEST

The outer surface of the lamp lenses shall be subjected once or more than once to the action of the sand jet produced as described above. The jet shall be sprayed almost perpendicular to the surface to be tested.

The deterioration shall be checked by means of one or more samples of glass placed as a reference near the lenses to be tested. The mixture shall be sprayed until the variation in the diffusion of light on the sample or samples measured by the method described in Appendix 2, is such that: Δd = (T5 – T4) / T2 = 0,0250 ± 0,0025 .

Several reference samples may be used to check that the whole surface to be tested has deteriorated homogeneously.

Appendix 4

ADHESIVE TAPE ADHERENCE TEST

1. PURPOSE

This method allows to determine under standard conditions the linear force of adhesion of an adhesive tape to a glass plate.

2. PRINCIPLE

Measurement of the force necessary to unstick an adhesive tape from a glass plate at an angle of 90 deg.

3. SPECIFIED ATMOSPHERIC CONDITIONS

The ambient conditions shall be at 23 οC ± 5 οC and 65 ± 15 per cent relative humidity.

4. TEST PIECES

Before the test, the sample roll of adhesive tape shall be conditioned for 24 hours in the specified atmosphere (see paragraph 3. above).

Five test pieces each 400 mm long shall be tested from each roll. These test pieces shall be taken from the roll after the first three turns were discarded.

5. PROCEDURE

The test shall be under the ambient conditions specified in paragraph 3.

Take the five test pieces while unrolling the tape radially at a speed of approximately 300 mm/s, then apply them within 15 seconds in the following manner:

Apply the tape to the glass plate progressively with a slight length- wise rubbing movement of the finger, without excessive pressure, in such a manner as to leave no air bubble between the tape and the glass plate.

Leave the assembly in the specified atmospheric conditions for 10 minutes.

Unstick about 25 mm of the test piece from the plate in a plane perpendicular to the axis of the test piece.

Fix the plate and fold back the free end of the tape at 90 deg. Apply force in such a manner that the separation line between the tape and the plate is perpendicular to this force and perpendicular to the plate.

Pull to unstick at a speed of 300 mm/s ± 30 mm/s and record the force required.

6. RESULTS

The five values obtained shall be arranged in order and the median value taken as a result of the measurement. This value shall be expressed in Newton per centimetre of width of the tape.









ANNEX 7

MINIMUM REQUIREMENTS FOR SAMPLING BY AN INSPECTOR

1. GENERAL

1.1. The conformity requirements shall be considered satisfied from a mechanical and a geometrical standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation. This condition also applies to colour.

1.2. With respect to photometric performances, the conformity of mass- produced systems shall not be contested if, when testing photometric performances of any system chosen at random and equipped with a light source energized, and if applicable corrected, as prescribed in paragraphs 1. and 2. of Annex 9 to this Regulation. 1.2.1. No value deviates unfavourably by more than 20 per cent from the value prescribed in this Regulation; 1.2.1.1. For the following values of the passing beam and its modes, the maximum unfavourable deviation may be respectively: — maximum values at point B50L 0,2 lx equivalent 20 per cent and 0,3 lx equivalent 30 per cent; — maximum values at zone III, HV and segment BLL: 0,3 lx equivalent 20 per cent and 0,45 lx equivalent 30 per cent; — maximum values at segments E, F1, F2 and F3: 0,2 lx equivalent 20 per cent and 0,3 lx equivalent 30 per cent; — minimum values at BR, P, S50, S50LL, S50RR, S100, S100LL, S100RR, and those required by footnote 4 of Table 1 in Annex 3 of this Regulation (B50L, HV, BR, BRR, BLL): half of the required value is equivalent to 20 per cent and three quarters of the required value equivalent to 30 per cent; 1.2.1.2. for the driving beam, HV being situated within the isolux 0,75 Emax, a tolerance of + 20 per cent for maximum values and 20 per cent for minimum values is observed for the photometric values at any measuring point specified in paragraph 6.3.2. of this Regulation. 1.2.2.
