5.3.3.1.

In addition, where the same lens is used, the latter may bear the different approval marks relating to the different types of headlamps or units of lamps, provided that the main body of the headlamp, even if it cannot be separated from the lens, also comprises the space described in paragraph 4.2 above and bears the approval mark of the actual functions.

If different types of headlamps comprise the same main body, the latter may bear the different approval marks.

5.3.3.2.

Annex 4, Figure 11, to this Regulation gives examples of arrangements of approval marks relating to the above case.

6.   GENERAL SPECIFICATIONS

6.1.

Each sample shall conform to the specifications set forth in this paragraph 6 and in paragraphs 7 and 8 below, and, if necessary, paragraph 9.

6.2.

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

6.2.1.

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 the SB headlamp inserts if the use of such inserts is confined to vehicles on which the headlamp setting can be adjusted by other means. Where an SB headlamp providing a driving beam and an SB headlamp providing a passing beam are assembled as exchangeable subunits to form a composite unit the adjusting device shall enable each SB unit individually to be duly adjusted.

6.2.2.

However, this will not apply to headlamp assemblies whose reflectors are indivisible. For this type of assembly the requirements of paragraph 8 of this Regulation shall apply. In the case where more than one light source is used to provide the main beam the combined main-beam functions will be used to determine the maximum value of the illumination (E max).

6.3.

The terminals shall only be in electrical connection with the appropriate filament or filaments and shall be robust and firmly fixed to the unit.

6.4.

If the units are circular they shall provide all the physical features and electrical connections shown in one of the plates SB2 — SB7 in Annex 4 and shall be made to the dimensions in that plate.

6.5.

SB units designed to meet the requirements both of countries where the traffic keeps to the right and of those where the traffic keeps to the left, 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 the angular setting of the unit on the vehicle. In all cases, only two precise setting positions, one for right-hand and one for left-hand traffic, shall be possible, and the design shall preclude inadvertent shifting of the unit from the one position to the other or its setting in an intermediate position. Conformity with the requirements of this paragraph shall be verified visually and, where necessary, by a test fitting.

6.6.

Complementary tests shall be done according to the requirements of Annex 5 to ensure that in use there is no excessive change in photometric performance.

6.7.

If the lens of the headlamp is of plastic material, tests shall be done according to the requirements of Annex 6.

7.   RATED VALUES

7.1.

The values of rated voltage are: 6, 12 and 24 volts (5).

7.2.

The power consumed at the test voltage by any submitted SB unit shall not exceed the rated wattage marked on the unit, by more than the percentage specified in Table 1. No lower limit is specified for the tolerance on wattage but the minimum illumination values specified in Table 2 of paragraph 8.8 must be obtained.

8.   ILLUMINATION (7)

8.1.

SB units shall be so made as to give adequate illumination without dazzle for the passing beam, and good illumination for the driving beam.

8.2.

The illumination produced by the unit shall be checked on a vertical screen set at a distance of 25 m in front of the unit and at right angles to its axis (see Annex 4, plates SB8a and SB8b).

8.3.

The passing beam must produce a sufficiently sharp ‘cut-off’ to permit satisfactory alignment with its aid. The ‘cut-off’ must be a horizontal line on the side opposite to the direction of the traffic for which the unit is intended; on the other side it should be horizontal or within an angle of 15° above the horizontal.

8.4.

The SB unit shall be aimed so that on passing beam:

8.4.1.

In the case of units designed to meet the requirements of right-hand traffic, the ‘cut-off’ on the left half of the screen (8) is horizontal and, in the case of units designed to meet the requirements of left-hand traffic, the ‘cut-off’ on the right half of the screen is horizontal;

8.4.2.

This horizontal part of the ‘cut-off’ is situated, on the screen, 25 cm below the level of the horizontal plane passing through the focus of the unit (see Annex 4, plates SB8a and SB8b);

8.4.3.

The screen is in the position indicated in Annex 4, plates SB8a and SB8b  (9).

8.5.

When so aimed, the unit need, if its approval is sought solely for a passing beam (10), meet only the requirements referred to in paragraph 8.8 below; if it is intended to provide both a passing beam and a driving beam it shall meet the requirements referred to in paragraphs 8.8 and 8.9.

8.6.

Where an SB unit so aimed does not meet the requirements referred to in paragraphs 8.8 and 8.9 below, its alignment may be changed, provided that the axis of the beam is not laterally displaced by more than 1° (= 44 cm) to the right or left (11). To facilitate alignment by means of the ‘cut-off’, the unit may be partially occulted in order to sharpen the ‘cut-off’.

8.7.

In the case of an SB unit providing a driving beam only, it shall be so aimed that the area of maximum illumination is centred on the point of intersection HV of the lines hh and vv; such a unit need meet only the requirements referred to in paragraph 8.9.

8.8.

The illumination produced on the screen by the passing beam shall meet the following requirements:

8.8.1.

There shall be no lateral variations detrimental to good visibility in any of the zones, I, II, III and IV;

8.8.2.

SB units designed to meet the requirements of both right-hand and left-hand traffic must, in each of the two setting positions, meet the requirements set forth above for the corresponding direction of traffic.

8.9.

In the case of an SB unit designed to provide a driving beam and a passing beam, measurements of the illumination produced on the screen by the driving beam shall be taken with the same unit alignment and voltage as for measurements under paragraph 8.8 above.

8.10.

The illumination produced on the screen by the driving beam shall meet the following requirements:

8.10.1.

The point of intersection HV of the line hh and vv shall be situated within the isolux 90 per cent of maximum illumination. The maximum value shall not be less than 32 lux;

8.10.2.

Starting from point HV, horizontally to the right and left, illumination shall be not less than 16 lux up to a distance of 1,125 metres, and not less than 4 lux up to a distance of 2,25 metres.

8.11.

The screen illumination values mentioned in paragraphs 8.8 and 8.9 above shall be measured by means of a photoelectric cell, the effective area of which shall be contained within a square of 65 mm side.

9.   COLOUR

The light emitted shall be white.

10.   GAUGING OF DISCOMFORT

The discomfort caused by the passing beam of SB units shall be gauged (12).

11.   CONFORMITY OF PRODUCTION

11.1.

Headlamps approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraphs 8 and 9.

11.2.

In order to verify that the requirements of paragraph 11.1 are met, suitable controls of the production shall be carried out.

11.3.

The holder of the approval shall in particular:

11.3.1.

ensure the existence of procedures for the effective control of the quality of products;

11.3.4.

analyse the results of each type of test in order to verify and ensure the stability of the product characteristics, making allowance for variation of an industrial production;

11.3.5.

ensure that for each type of product at least the tests prescribed in Annex 3 to this Regulation are carried out;

11.3.6.

ensure that any collecting of samples giving evidence of non-conformity with the type of test considered shall give rise to another sampling and another test. All the necessary steps shall be taken to re-establish the conformity of the corresponding production.

11.4.

The Competent Authority which has granted type approval may at any time verify the conformity control methods applicable to each production unit.

11.4.1.

In every inspection, the test books and production survey records shall be presented to the visiting inspector.

11.4.2.

The inspector may take samples at random to be tested in the manufacturer’s laboratory. The minimum number of samples may be determined in the light of the results of the manufacturer’s own checks.

11.4.3.

When the quality level appears unsatisfactory or when it seems necessary to verify the validity of the tests carried out in the application of paragraph 11.4.2 above, the inspector shall select samples, to be sent to the Technical Service which has conducted the type approval tests, using the criteria of Annex 7.

11.4.4.

The Competent Authority may carry out any test prescribed in this Regulation. These tests will be on samples selected at random without causing distortion of the manufacturer’s delivery commitments and in accordance with the criteria of Annex 7.

11.4.5.

The Competent Authority shall strive to obtain a frequency of inspection of once every two years. However, this is at the discretion of the Competent Authority and their confidence in the arrangements for ensuring effective control of the conformity of production. In the case where negative results are recorded, the Competent Authority shall ensure that all necessary steps are taken to re-establish the conformity of production as rapidly as possible.

11.5.

Headlamps with apparent defects are disregarded.

11.6.

The reference mark is disregarded.

12.   PENALTIES FOR NON-CONFORMITY OF PRODUCTION

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 SB headlamp which has been aged for at least one hour 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 vv and the vertical line passing through point B 50 L for right-hand traffic or B 50 R for left-hand traffic) shall be verified 3 minutes (r3) and 60 minutes (r60) respectively after operation.

The measurement of the variation in the cut-off line position as described above shall be carried out by any method giving acceptable accuracy and reproducible results.

2.2.   Test results

2.2.1.

The result expressed in milliradians (mrad) shall be considered as acceptable when the absolute value

Formula

recorded on the headlamp is not more than 1,0 mrad (Δ rI ≤ 1,0 mrad).

2.2.2.

However, if this value is more than 1,0 mrad but not more than 1,5 mrad (1,0 mrad < Δ rI ≤ 1,5 mrad) a second headlamp shall be tested as described in 2.1 after being subjected three consecutive times to the cycle as described below, in order to stabilize the position of mechanical parts of the headlamp on a base representative of the correct installation on the vehicle:

Operation of the passing lamp for one hour, (the voltage shall be adjusted as specified in paragraph 1.1.1.2),

Period of rest for one hour.

The headlamp type shall be considered as acceptable if the mean value of the absolute values Δ rI measured on the first sample and Δ rII measured on the second sample is not more than 1,0 mrad

Formula


(1)  When the tested headlamp is grouped and/or reciprocally incorporated with 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 operation mode with an on/off time ratio of approximately one to one.

(2)  Should two filaments be simultaneously lit when headlamp flashing is used, this shall not be considered as being normal use of both filaments simultaneously.

(3)  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 200-300 cP for a 2 per cent solution at 20 °C.

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

(5)  50 V is situated 375 mm below HV on the vertical line v-v on the screen at 25 m distance.

METHOD OF MEASUREMENT OF THE DIFFUSION AND TRANSMISSION OF LIGHT

1.   EQUIPMENT (see figure)

The beam of a collimator K with a half divergence Formula 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 Formula and Formula 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:

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 1/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:

Formula

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°.

3.   SPECIFIED ATMOSPHERIC CONDITIONS

The ambient conditions shall be at 23 °C ± 5 °C and 65 ± 15 per cent relative humidity (RH).

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 lengthwise 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°. 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 the result of the measurement. This value shall be expressed in Newtons per centimetre of width of the tape.
