2.                DEFINITIONS

                   For the purpose of this Regulation,

2.1.             "Halogen  sealed-beam  headlamp  unit"  (hereinafter  termed  "HSB  unit")  means  a headlamp whose components, including a reflector of glass, metal or other material, an optical system and one or more halogen light sources, form an integral whole which is indivisibly joined and cannot be dismantled without rendering the unit completely unusable.  Such units are:

2.1.1.          of "category 1", when they emit only a driving beam;

2.1.2.          of "category 21", when they emit only a passing beam;

2.1.3.          of "category 22", when they emit, at the user's choice, either a driving beam or a passing beam;

2.2.             "Lens" means the outermost component of the headlamp (unit) which transmits light through the illuminating surface;

2.3.             "Coating" means any product or products applied in one or more layers to the outer face of a lens;

2.4.             "HSB units of different types" means units which differ in such essential respects as:

2.4.1.          the trade name or mark;

2.4.2.          the characteristics of the optical system;

2.4.3.          the inclusion or elimination of components capable of altering the optical effects by reflection, refraction, absorption and/or deformation during operation; the fitting or elimination of filters intended solely to change the colour of the beam but not its light distribution does not constitute a change of type;

2.4.4.          the rated voltage;

2.4.5.          the shape of the filament or filaments;

2.4.6.          the kind of beam produced (passing beam, driving beam or both);

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

5.3.3.2.       Annex 2, figure 9, to this Regulation gives examples of arrangements of approval marks relating to the above case.

6.                GENERAL SPECIFICATIONS

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

6.2.             HSB units shall be so designed and made that in normal use, despite the vibrations to which they may then be subjected, their satisfactory operation continues to be ensured and they retain the characteristics prescribed by this Regulation.

6.2.1.          HSB optical units 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 HSB optical unit insert if the use of such inserts is confined to vehicles on which the headlamp setting can be adjusted by other means.

                   Where an HSB optical unit providing a driving beam and an HSB optical unit providing a passing beam are assembled as exchangeable subunits to form a composite unit, the adjusting device shall enable each HSB 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 8.3. 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 (EM).

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

6.4.             HSB units shall comprise electrical connections in conformity with those shown in one of the patterns reproduced in annex 3 to this Regulation and shall be of the dimensions specified in that annex.

6.5.             Complementary tests shall be done according to the requirements of annex 6 to ensure that in use there is no excessive change in photometric performance.

6.6.             If the lens of the HSB unit is of plastic material, tests shall be done according to the requirements of annex 7.

7.                RATED AND TEST VALUES

7.1.             The rated voltage is 12 volts. 4/

7.2.             The wattage shall not exceed 75 watts on the driving beam filament and 68 watts on the passing beam filament measured at a test voltage of 13.2 volts.

8.                ILLUMINATION 5/

8.1.             General specifications

8.1.1.          HSB units shall be made so as to give adequate illumination without dazzle when emitting the passing beam and good illumination when emitting the driving beam.

8.1.2.          The illumination produced by the HSB unit shall be determined by means of a vertical screen set up 25 m forward of the unit as shown in annex 4 to this Regulation. 6/

8.1.3.          On this screen, the illumination referred to in paragraphs 8.2.5., 8.2.6. and 8.3. below shall be measured by means of a photoreceptor, the effective area of which shall be contained within a square of 65 mm side.

8.2.             Requirements concerning the passing beam

8.2.1.          The passing beam shall produce a "cut-off" I sharp enough to serve as a satisfactory means of adjustment.  The "cut-off" shall be a horizontal straight line on the side opposite to the direction of the traffic for which the unit is intended. on the other side it shall not extend beyond either the broken line HV H1 H4 formed by a straight line HV    H1 making a 45 degrees angle with the horizontal and a straight line H1 H4, 25 cm above the straight line hh, or the straight line HV H3, inclined at an angle of 15 degrees above the horizontal (see annex 4 to this Regulation).  A "cut-off" extending beyond both line HV H2 and line H2 H4 and resulting from a combination of the above two possibilities shall in no circumstances be permitted.

8.2.2.          The HSB unit shall be so aimed that on the passing beam:

8.2.2.1.       in the case of HSB units designed to meet the requirements of right-hand traffic, the "cut-off" on the left half of the screen 7/ is horizontal and, in the case of HSB units designed to meet the requirements of left-hand traffic, the "cut-off" on the right half of the screen is horizontal;

8.2.2.2.       this horizontal part of the "cut-off" is situated on the screen 25 cm below the level hh (see annex 4 to this Regulation);

8.2.2.3.       The "elbow" of the "cut-off" is on line vv. 8/

8.2.3.          When  so  adjusted,  the  HSB  unit  need  meet  only  the  requirements  laid  down  in paragraphs 8.2.5. and 8.2.6. below if approval thereof is sought solely for provision of a passing beam; 9/ if it is intended to provide both a passing beam and a driving beam it shall meet the requirements laid down in paragraphs 8.2.5., 8.2.6. and 8.3.


8.2.4.          Where an HSB unit so adjusted does not meet the requirements laid down in paragraphs 8.2.5., 8.2.6. and 8.3., its alignment may be changed provided that the axis of the beam   is not displaced laterally by more than 1 degrees (= 44 cm) to the right or left. 10/ To facilitate alignment by means of the "cut-off", the unit may be partially occulted in order to sharpen the "cut-off".

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

* E50R and E50L are the illuminations actually measured.

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

8.3.             Requirements concerning the driving beam

8.3.1.          In the case of an HSB 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 HSB unit alignment as for measurements under paragraphs 8.2.5. and 8.2.6.; if the HSB unit provides a driving beam only, it shall be so adjusted that the area of maximum illumination is centred on the point of intersection HV of lines hh and vv; such an HSB unit need meet only the requirements laid down in paragraph 8.3.

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

8.3.2.1.       The point of intersection HV of lines hh and vv shall be situated within the isolux 80% of maximum illumination.  This maximum value (EM) shall not be less than 48 lux.  The maximum value (EM) shall not exceed 240 lux; in addition, in the case of a combined passing and driving HSB unit, it shall in no case exceed 16 times the illumination measured for the passing beam at point 75 R (or 75 L).

8.3.2.1.1.    The maximum intensity (IM) of the driving beam expressed in thousands of candelas shall be calculated by the formula:

                   IM = 0.625 EM

8.3.2.1.2.    The reference mark (I'M) of this maximum intensity, referred to in paragraph 5.2.2.5., shall be obtained by the ratio:

                   This value shall be rounded off to the nearest value 7.5  12.5 - 17.5  25 - 27.5  37.5  45 - 50.

8.3.2.2.       Starting from point HV, horizontally to the right and left, the illumination shall be not less than 24 lux up to a distance of 1.125 m and not less than 6 lux up to a distance of 2.25 m.

9.                COLOUR

9.1.             Approval may be obtained for HSB units emitting either white or selective yellow light.11/ Expressed in CIE trichromatic coordinates, the corresponding colorimetric characteristics for selective yellow light are as follows at the test voltage:

Limit towards red

y > 0.138 + 0.580x

Limit towards green

y < 1.290x - 0.100

Limit towards white

y > -x + 0.966

Limit towards spectral value

y < -x + 0.992

which can be expressed as follows:

 

dominant wave length:

575 to 585 nm

purity factor:

0.90 to 0.98

9.2.             The illumination produced on the screen by a selective yellow passing beam shall meet the  requirements  of  paragraphs  8.2.5.  and  8.2.6.  with  the  minimum  illuminations multiplied by a factor of 0.85; the maximum illumination values remain the same.

METHOD OF MEASUREMENT OF THE DIFFUSION AND TRANSMISSION OF LIGHT

1.                EQUIPMENT (see figure)

                   The beam of a collimator K with a half divergence

                   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 beta/2 = 14 degrees .

                   An annular diaphragm DD with angles

                   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 eterioration, 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.


Annex 7 - 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 degrees.

3.                SPECIFIED ATMOSPHERIC CONDITIONS

                   The ambient conditions shall be at 23 degrees C +/- 5 degrees C and 65 +/- 15% 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 para. 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 degrees.  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.

B.                  TECHNICAL REQUIREMENTS FOR HEADLAMPS [6]/

 

5.                  GENERAL SPECIFICATIONS

 

5.1.               Each sample shall conform to 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 vehicles 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 headlamp setting can be adjusted by other means.

 

                     Where a headlamp providing a passing beam and a headlamp providing a driving beam, each equipped with its own filament lamp, are assembled to form a composite unit the adjusting device shall enable each optical system individually to be duly adjusted.

 

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 apply.

 

5.3.               The headlamp shall be equipped with filament lamp(s) approved according to Regulation No. 37.  Any Regulation No. 37 filament lamp may be used, provided that no restriction on the application is made in the table of contents of Regulation No. 37. [7]/

 

5.4.               The components by which a filament lamp is fixed to the reflector shall be so made that, even in darkness, the filament lamp can be fixed in no position but the correct one. [8]/

 

5.5.               The filament lamp holder shall conform to the characteristics given in IEC Publication 61-2, third edition, 1969.  The holder data sheet relevant to the category of filament lamp used, applies.

 

5.6.               Headlamps designed to satisfy the requirements both of 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 filament lamp 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 filament lamp, the components for attaching the filament lamp to the reflector must be so designed and made that, in each of its two settings, the filament lamp 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.

 

5.7.               Complementary tests shall be done according to the requirements of Annex 4 to ensure that in use there is no excessive change in photometric performance.

 

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

 

5.9.               On headlamps designed to provide alternately a driving beam and a passing beam, or a passing beam and/or a driving beam designed to become bend lighting, any mechanical, electromechanical or other device incorporated in the headlamp for these purposes shall be so constructed that:

 

5.9.1.            the device is strong enough to withstand 50,000 operations without suffering damage despite the vibrations to which it may be subjected in normal use;

 

5.9.2.            in the case of failure the illumination above the line H-H shall not exceed the values of a passing beam according to paragraph 6.2.5.; in addition, on headlamps designed to provide a passing and/or a driving beam to become a bend lighting, a minimum illumination of at least 5 lux shall be fulfilled in test point 25 V (VV line, D 75 cm).

 

5.9.3.            either the passing beam or the driving beam shall always be obtained without any possibility of the mechanism stopping in between two positions;

 

5.9.4.            the user cannot, with ordinary tools, change the shape or position of the moving parts.

 

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 the driving beam.

 

6.1.2.            The illumination produced by the headlamp shall be determined by means of a vertical screen set up 25 m forward of the headlamp and at right angles to its axes as shown in Annex 3 to this Regulation.

 

6.1.3.            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 as indicated at the relevant data sheet of Regulation No. 37.

 

6.1.4.                        The headlamp shall be considered acceptable if it meets the requirements of this paragraph 6 with at least one standard (étalon) filament lamp, which may be submitted with the headlamp.

 

6.2.               Provisions concerning passing beams

 

6.2.1.            The passing beam must produce a sufficiently sharp "cut-off" to permit a satisfactory adjustment with its aid. The "cut-off" must be a horizontal straight line on the side opposite to the direction of the traffic for which the headlamp is intended; on the other side, it must not extend beyond either the broken line HV H1 H4 formed by a straight line HV H1 making a 45° angle with the horizontal and the straight line H1 H4, 25 cm above the straight line hh, or the straight line HV H3, inclined at an angle of 15° above the horizontal (see Annex 3).  A cut-off extending beyond both line HV H2 and line H2 H4 and resulting from a combination of the two above possibilities shall in no circumstances be permitted.

 

6.2.2.            The headlamp shall be so aimed that:

 

6.2.2.1.         in the case of headlamps designed to meet the requirements of right-hand traffic, the "cut-off" on the left-half of the screen [9]/ is horizontal and, in the case of headlamps designed to meet the requirements of left-hand traffic, the "cut-off" on the right-half of the screen is horizontal;

 

6.2.2.2.         this horizontal part of the "cut-off" is situated on the screen 25 cm below the level hh (see Annex 3);

 

6.2.2.3.         the "elbow" of the "cut-off" is on line vv. [10]/

 

6.2.3.            When so aimed, the headlamp need, if its approval is sought solely for provision of a passing beam, [11]/ comply only with the requirements set out in paragraphs 6.2.5. to 6.2.7. and 6.2.9. 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. to 6.2.7. and 6.3.

 

6.2.4.            Where a headlamp so aimed does not meet the requirements set out in paragraphs 6.2.5. to 6.2.7. and 6.3., its alignment may be changed, provided that the axis of the beam is not displaced laterally by more than 1° (= 44 cm) to the right or left. [12]/ To facilitate alignment by means of the "cut-off", the headlamp may be partially occulted in order to sharpen the "cut-off".

 

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

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

 

6.2.7.            The illumination values in zones "A" and "B" as shown in figure C in Annex 3 shall be checked by the measurement of the photometric values of points 1 to 8 on this figure; these values shall lie within the following limits: [13]/

 

1  +  2  +  3 >  0.3 lux, and

 

4  +  5  +  6 >  0.6 lux, and

                                             0.7 lux >  8  >  0.2 lux

 

6.2.8.            Headlamps designed to meet the requirements of both right-hand and left-hand traffic must, in each of the two setting positions of the optical unit or of the filament lamp, meet the requirements set forth above for the corresponding direction of traffic.

 

6.2.9.            The requirements in paragraph 6.2.5. above shall also apply to headlamps designed to provide bend lighting and/or that include the additional light source referred to in paragraph 6.2.10.2.  In the case of a headlamp designed to provide bend lighting its alignment may be changed, provided that the axis of the beam is not displaced vertically by more than 0.2 °.

 

6.2.9.1.         If bend lighting is obtained by:

 

6.2.9.1.1.      swivelling the passing beam or moving horizontally the kink of the elbow of the cut-off, the measurements shall be carried out after the complete headlamp assembly has been reaimed horizontally, e.g. by means of a goniometer;

 

6.2.9.1.2.      moving one or more optical parts of the headlamp without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with these parts being in their extreme operating position;

 

6.2.9.1.3.      means of one additional light source without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with this light source activated.

 

6.2.10.          Only one principal light source is permitted for each passing beam headlamp.  However, a maximum of two additional light sources are permitted as follows:

 

6.2.10.1.       One additional light source inside the passing beam headlamp according to Regulation No. 37 may be used to contribute to bend lighting.

 

6.2.10.2.       One additional light source according to Regulation No. 37, inside the passing beam headlamp, may be used for the purposes of generating infrared radiation.  It shall only be activated at the same time as the principal light source.  In the event that the principal light source fails, this additional light source shall be automatically switched off.

 

6.2.10.3.       In the event of failure of an additional light source, the headlamp shall continue to fulfil the requirements of the passing beam.

 

6.3.               Provisions concerning driving beams

 

6.3.1.            In the case of a headlamp 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 headlamp alignment as for measurements under paragraphs 6.2.5. to 6.2.7. above; in the case of a headlamp providing a driving beam only, it shall be so adjusted that the area of maximum illumination is centred on the point of intersection of lines hh and vv; such a headlamp need meet only the requirements referred to in paragraph 6.3.

 

6.3.2.            It is possible to use several light sources for the driving beam.

 

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

 

6.3.3.1.         The point of intersection (HV) of lines hh and vv shall be situated within the isolux 80 per cent of maximum illumination. This maximum value (EM) shall not be less than 32 lux for Class A headlamps and 48 lux for Class B headlamps.  The maximum value shall in no circumstances exceed 240 lux; in addition, in the case of a combined passing and driving headlamp, this maximum value shall not be more than 16 times the illumination measured for the passing beam at point 75 R (or 75 L).

 

6.3.3.1.1.      The maximum intensity (IM) of the driving beam expressed in thousands of candelas shall be calculated by the formula:

 

                     IM = 0.625 EM

 

6.3.3.1.2.      The reference mark (I'M) of this maximum intensity, referred to in paragraph 4.2.2.7. above, shall be obtained by the ratio:

 

Text Box:                      

 

 

                     This value shall be rounded off to the value 7.5 - 10 - 12.5 - 17.5 - 20 - 25 - 27.5 - 30 - 37.5 - 40 - 45 - 50.

 

6.3.3.2.         Starting from point HV, horizontally to the right and left, the illumination shall be not less than 16 lux for Class A headlamp and 24 lux for Class B headlamp up to a distance of 1.125 m and not less than 4 lux for Class A headlamp and 6 lux for Class B headlamp up to a distance of 2.25 m.

 

6.4.               In the case of headlamps with adjustable reflector the requirements of paragraphs 6.2. and 6.3. are applicable for each mounting position indicated according to paragraph 2.1.3.  For verification the following procedure shall be used:

 

6.4.1.            Each applied position is realized on the test goniometer with respect to a line joining the centre of the light source and point HV on a aiming screen.  The adjustable reflector is then moved into such a position that the light pattern on the screen corresponds to the aiming prescriptions of paragraphs 6.2.1. to 6.2.2.3. and/or 6.3.1;

 

6.4.2.            with the reflector initially fixed according to paragraph 6.4.1., the headlamp must meet the relevant photometric requirements of paragraphs 6.2. and 6.3;

 

6.4.3.            additional tests are made after the reflector has been moved vertically ± 2° or at least into the maximum position, if less than 2°, from its initial position by means of the headlamps adjusting device. Having re-aimed the headlamp as a whole (by means of the goniometer for example) in the corresponding opposite direction the light output in the following directions shall be controlled and lie within the required limits:

 

                     passing beam :              points HV and 75 R (75 L respectively);

                     driving beam :               EM and point HV (percentage of EM).

 

6.4.4.            if the applicant has not indicated more than one mounting position,  the procedure of paragraphs 6.4.1. to 6.4.3. shall be repeated for all other positions;

 

6.4.5.            if the applicant has not asked for special mounting positions, the headlamp shall be aimed for measurements of paragraphs 6.2. and 6.3. with the headlamps adjusting device in its mean position.  The additional test of paragraph 6.4.3. shall be made with the reflector moved into its extreme positions (instead of + 2°) by means of the headlamps adjusting device.

 

6.5.               The screen illumination values mentioned in paragraphs 6.2.5. to 6.2.7. and 6.3. above shall be measured by means of a photo receptor, the effective area of which shall be contained within a square of 65 mm side.

 

7.                  COLOUR

 

7.1.               The colour of the light emitted shall be white. Expressed in CIE trichromatic coordinates, the light of the beams shall be in the following boundaries:

 

limit towards blue                     :      x > 0.310

limit towards yellow                  :      x < 0.500

limit towards green                   :      y < 0.150 + 0.640 x

limit towards green                   :      y < 0.440

limit towards purple                  :      y > 0.050 + 0.750 x

limit towards red                       :      y > 0.382

 

8.                  GAUGING OF DISCOMFORT

 

                     The discomfort caused by the passing beam of headlamps shall be gauged. [14]/

 

C.                 FURTHER ADMINISTRATIVE PROVISIONS

2.                 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 passing lamp.

 

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, 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 in milliradians (mrad) shall be considered as acceptable for a passing lamp, only when the absolute value DrI = | r3 - r60 | recorded on the headlamp is not more than 1.0 mrad (DrI < 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 < ?rI < 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:

METHOD OF MEASUREMENT OF THE DIFFUSION  AND TRANSMISSION OF LIGHT

 

1.         EQUIPMENT (see figure)

 

The beam of a collimator K with a half divergence ß/2 = 17.4 x 104 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 ß/2 = 14°.

 

An annular diaphragm DD, with angles ao/2 = 1° and amax /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 [25]/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:

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.

 

 

 


Annex 6 - 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 para. 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.

5.2.1.          Headlamps shall be fitted with a device enabling them to be so adjusted on the vehicles as to comply with the rules applicable to them.  Such a device may or may not provide horizontal adjustment, provided that the headlamps are so designed that they can maintain a proper horizontal aiming even after the vertical aiming adjustment.  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 headlamp setting can be adjusted by other means.

 

                   Where a headlamp providing a passing beam and a headlamp providing a driving beam, each equipped with its own filament lamp, are assembled to form a composite unit the adjusting device shall enable each optical system individually to be duly adjusted.

 

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 apply.

 

5.3.             The headlamp shall be equipped with filament lamp(s) approved according to Regulation No. 37.  Any Regulation No. 37 filament lamp may be used, provided that:

 

(a)     no restriction on the application is made in the table of contents of that Regulation;

 

                   (b)     for Class A and B, its reference luminous flux for dipped-beam does not exceed 600 lm;

 

                   (c)     for Class C and D, its objective luminous flux for dipped-beam does not exceed 2000 lm.

 

5.4.             The components by which a filament lamp is fixed to the reflector shall be so made that, even in darkness, the filament lamp can be fixed in no position but the correct one. [33]/

 

5.5.             The filament lamp holder shall conform to the characteristics given in IEC Publication 61-2, third edition, 1969.  The holder data sheet relevant to the category of filament lamp used, applies.

 

5.6.             In addition, Class B or C or D headlamps shall be complementary tested according to the requirements of Annex 4 to ensure that in use there is no excessive change in photometric performance.

 

5.7.             If the lens of a Class B or C or D headlamp is of plastic material, tests shall be done according to the requirements of Annex 6.

 

5.8.             On headlamps designed to provide alternately a driving beam and a passing beam, any mechanical, electromechanical or other device incorporated in the headlamp for switching from one beam to the other shall be so constructed that:

 

5.8.1.          the device is strong enough to withstand 50,000 operations without suffering damage despite the vibrations to which it may be subjected in normal use;

 

5.8.2.          in the case of  failure it shall automatically obtain the passing beam position;

 

5.8.3.          either the passing beam or the driving beam shall always be obtained without any possibility of the mechanism stopping in between the two positions;

 

5.8.4.          the user cannot, with ordinary tools, change the shape or position of the moving parts.

 

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 illumination produced by the headlamp shall be determined by means of a vertical screen set up 25 m forward of the headlamp and at right angles to its axes as shown in Annex 3 to this Regulation.

 

6.1.3.          Headlamps shall be checked by means of an uncoloured standard (étalon) filament lamp designed for a rated voltage as indicated in the relevant data sheet of Regulation No. 37.  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 as indicated at the relevant data sheet of Regulation No. 37.

 

6.1.4.          The headlamp shall be considered acceptable if it meets the requirements of this paragraph 6 with at least one standard (étalon) filament lamp, which may be submitted with the headlamp.

 

6.2.             Provisions concerning passing beams

 

6.2.1.          For a correct aiming the passing beam shall produce a sufficiently sharp "cut-off" to permit a satisfactory visual adjustment with its aid as indicated in paragraph 6. below.  The "cut-off" must be substantially horizontal and shall be as straight as possible from at least 3° L to 3° R for Class A, B, C and D headlamps.  In case that 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 headlamp shall be so aimed 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 1 per cent below the H-H-line which is 10 cm below the headlamp axis on the screen at 10 m distance or which is 25 cm below the headlamp axis on the screen at 25 m distance.

 

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 need, if its approval is sought solely for provision of a passing beam, [34]/ comply only with the requirements set out in paragraphs 6.2.5. to 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 1 degree (= 44 cm) to the right or left [35]/.  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 illumination produced by the passing beam on the screens in Annex 3 shall meet the following illumination requirements:

 

6.2.5.1.       For Class A headlamps:

 

Any point on and above the line H-H

            £ 0.32 lux

Any point on line 25L-25R

            ³ 1.28 lux

Any point on line 12.5L-12.5R

            ³ 0.64 lux

 

6.2.5.2.       For Class B headlamps:

 

Any point on and above the line H-H

           £ 0.7 lux

Any point on line 50L-50R except 50V */

           ³ 1.5 lux

Point 50V
