6. ILLUMINATION

6.1. General provisions

6.1.1. Headlamps shall be so made that they give adequate illumination without dazzle when emitting the passing beam, and good illumination when emitting a driving beam.

6.1.2. The luminous intensity produced by the headlamp shall be measured at 25 m distance by means of a photoelectric cell having a useful area comprised within a square of 65 mm side. The point HV is the centre-point of the coordinate system with a vertical polar axis. Line H is the horizontal through HV (see Annex 3 to this Regulation).

6.1.3. For Class A or B or C or D

6.1.3.1. Apart from (an) LED module(s), the headlamps shall be checked by means of an uncoloured standard (étalon) filament lamp designed for a rated voltage of 12 V. During the checking of the headlamp, the voltage at the terminals of the filament lamp shall be regulated so as to obtain the reference luminous flux at 13,2 V as indicated at the relevant data sheet of Regulation No 37.

In order to protect the standard (étalon) filament lamp during the process of photometric measurement it is permissible to carry out the measurements at a luminous flux that differs from the reference luminous flux at 13,2 V. If the test laboratory chooses to carry out measurements in such a manner the luminous intensity shall be corrected by multiplying the measured value by the individual factor Flamp of the standard (étalon) filament lamp in order to verify the compliance with the photometric requirements where:

Flamp = Φreference/Φtest

Φreference is the reference luminous flux at 13,2 V as specified in the relevant data sheet of Regulation No 37

Φtest is the actual luminous flux used for the measurement.

6.1.3.2. Depending on the number of filament lamps for which the headlamp is designed, it shall be considered acceptable if it meets the requirements of paragraph 6 with the same number of standard (étalon) filament lamp(s), which may be submitted with the headlamp.

6.1.3.3. LED module(s) shall be measured at 6,3 V or 13,2 V respectively, if not otherwise specified within this Regulation. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.

6.1.4. For Class E with (a) gas-discharge light source(s) according to Regulation No 99

6.1.4.1. The headlamp shall be deemed satisfactory if the photometric requirements set in the present paragraph 6 are met with one light source, which has been aged during at least 15 cycles, in accordance with Annex 4, paragraph 4 of Regulation No 99.

Where the gas-discharge light source is approved according to Regulation No 99 it shall be a standard (étalon) light-source and its luminous flux may differ from the objective luminous flux specified in Regulation No 99. In this case, the illuminances shall be corrected accordingly.

The above correction does not apply to distributed lighting systems using a non-replaceable gas-discharge light source or to headlamps with the ballast(s) totally or partially integrated.

Where the gas-discharge light source is not approved according to Regulation No 99 it shall be a production non-replaceable light source.

The voltage applied to the terminals of the ballast(s) is: either: 13,2 V ± 0,1 V for 12 V systems or: as otherwise specified (see Annex 11).

6.1.4.2. The dimensions determining the position of the arc inside the standard gas-discharge light source are shown in the relevant data sheet of Regulation No 99.

6.1.4.3. Four seconds after ignition of a headlamp which has not been operated for 30 minutes or more, at least 37 500 cd must be reached at point HV of a driving beam and 3 750 cd at point 2 (0,86 D-V) of a passing beam for headlamps incorporating driving beam and passing beam functions, or 3 750 cd at point 2 (0,86 D-V) for headlamps having only a passing beam function. The power supply shall be sufficient to secure the quick rise of the high current pulse.

6.1.5. For Class E with (an) LED module(s)

6.1.5.1. LED module(s) shall be measured at 6,3 V or 13,2 V respectively, if not otherwise specified within this Regulation. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.

6.1.6. In the case of headlamp systems having additional light source(s) and/or additional lighting unit(s) used to produce bend lighting, the additional light source(s) shall be measured according to the paragraphs 6.1.3, 6.1.4 and 6.1.5.

6.2. Provisions concerning passing beams

6.2.1. For a correct aiming the principal passing beam shall produce a sufficiently sharp ‘cut-off’ to permit a satisfactory visual adjustment with its aid as indicated in paragraph 6.2.2 below. The aiming shall be carried out using a flat vertical screen set up at a distance of 10 or 25 m forward of the headlamp and at right angles to the H-V. The screen shall be sufficiently wide to allow examination and adjustment of the ‘cut-off’ of the passing beam over at least 3° on either side of the V-V line. The ‘cut-off’ shall be substantially horizontal and shall be as straight as possible from at least 3° L to 3° R. In case the visual aim leads to problems or ambiguous positions, the instrumental method as specified in Annex 9, paragraphs 2 and 4, shall be applied and the quality or rather the sharpness of the ‘cut-off’ and the linearity shall be checked on performance.

6.2.2. The principal passing beam shall be aimed so that:

6.2.2.1. For horizontal adjustment: The beam is as symmetrical as possible with reference to line V-V;

6.2.2.2. For vertical adjustment: the horizontal part of the ‘cut-off’ line is adjusted to its nominal position (0,57 degree) below the H-H line. If, however, vertical adjustment cannot be performed repeatedly to the required position within the allowed tolerances, the instrumental method of Annex 9, paragraphs 4 and 5 shall be applied to test compliance with the required minimum quality of the ‘cut-off’ line and to perform the beam vertical adjustment.

6.2.3. When so aimed, the headlamp must, if its approval is sought solely for provision of a passing beam (10), comply with the requirements set out in paragraphs 6.2.5 and 6.2.6 below; if it is intended to provide both a passing beam and a driving beam, it shall comply with the requirements set out in paragraphs 6.2.5, 6.2.6 and 6.3.

6.2.4. Where a headlamp so aimed does not meet the requirements set out in paragraphs 6.2.5, 6.2.6 and 6.3, its alignment may be changed, except for headlamps that have no mechanism to adjust horizontal aim, on condition that the axis of the beam is not displaced laterally by more than 0,5 degree to the right or left and vertically by not more than 0,25 degree up or down. To facilitate alignment by means of the ‘cut-off’, the headlamp may be partially occulted in order to sharpen the ‘cut-off’. However, the ‘cut-off’ should not extend beyond the line H-H.

6.2.5. The passing beam shall meet the requirements as shown in the applicable table below and the applicable figure as shown in Annex 3.

Notes:

For Class E headlamps the voltage applied to the terminals of the ballast(s) is either 13,2 V ± 0,1 V for 12 V systems or as otherwise specified (see Annex 11).

‘D’ means under the H-H line. ‘U’ means above the H-H line. ‘R’ means right of the V-V line. ‘L’ means left of the V-V line.

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. 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 in milliradians (mrad) shall be considered as acceptable for a headlamp producing a passing beam, only when the absolute value recorded on the headlamp is not more than 1,0 mrad (Δr I ≤ 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 < ΔrI ≤ 1,5 mrad) a second headlamp shall be tested as described in paragraph 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 beam 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 ΔrI measured on the first sample and ΔrII measured on the second sample is not more than 1,0 mrad. (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.

Equipment (see figure) The beam of a collimator K with a half divergence β/2 = 17,4 × 104 rd 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°. 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 Dτ and the focal length F2 (1) of the lens L2 shall be so chosen that the image of Dτ 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 T5 yes (after test) yes Flux diffused by the tested material (1) For L2 it is recommended to use a focal distance of about 80 mm. Appendix 3 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: 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 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 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°. 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 Newtons 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 in accordance with the requirements of this Regulation, if any, if the differences do not exceed inevitable manufacturing deviations. This condition also applies to colour. 1.2. For Classes A, B, C and D headlamps: 1.2.1. With respect to photometric performances, the conformity of mass-produced headlamps shall not be contested if, when testing photometric performances of any headlamp chosen at random and equipped with standard filament lamp(s) and/or LED module(s) as present in the headlamp: 1.2.2. Class A headlamps: no measured value deviates unfavourably by more than 20 per cent from the value prescribed in this Regulation. 1.2.3. Classes B, C and D headlamps: 1.2.3.1. No measured value deviates unfavourably by more than 20 per cent from the value prescribed in this Regulation. For values in zone 1 for Classes B, C and D headlamps, the maximum unfavourable deviation may be respectively: 255 cd equivalent 20 per cent 380 cd equivalent 30 per cent 1.2.3.2. And if for the driving beam 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 6.3.3.1 or 6.3.3.2 of this Regulation. 1.2.4. If the results of the tests described above do not meet the requirements, tests shall be repeated using other standard filament lamp(s). 1.2.5. If the results of the tests described above do not meet the requirements, the alignment of the headlamp may be changed, provided that the axis of the beam is not displaced laterally by more than 0,5 degree to the right or left and not by more than 0,2 degree up or down. 1.3.
