5.3.             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 components in which the reflector and the diffusing lens cannot be separated provided the use of such units is confined to vehicles on which the headlamps setting can be adjusted by other means.  Where a headlamp providing a driving beam and a headlamp providing a passing 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.

                   However, this shall not apply to headlamps assemblies whose reflectors are indivisible. For this type of assembly, the requirements of Paragraph 6 shall apply.

5.4.             The components by which the 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. The filament lamp-holder shall conform to the dimensional characteristics as given in the following data sheets of IEC Publication 61-2:

5.5.             Headlamps designed to satisfy the requirements both of countries in which traffic moves on the right and of those in which it moves on the left may be adapted for traffic on a given side of the road either by an appropriate initial adjustment when the vehicle is   fitted out or by selective setting by the driver.  Such initial adjustment or selective setting shall 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 precisely differentiated setting positions, one for right-hand and one for left-hand traffic, shall be possible, and the design shall preclude inadvertent shifting of the headlamp    from one position to another or its setting in an intermediate position.  Where two different setting positions are provided for the filament lamp, the components attaching the filament lamp to the reflector must be so designed and manufactured that, in each of its two settings, the filament lamp will be held in position with the precision required for headlamps intended for traffic on only one side of the road.

5.6.             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.

5.7.             Conformity with the requirements of Paragraphs 5.2 to 5.5 shall be verified visually and, where necessary, by a test fitting.

5.8              If the lens of the headlamp is of plastic material, tests shall be done according to the requirements of Annex 7.

6.                ILLUMINATION

6.1.             Headlamps shall be so made that with suitable R2 and/or HS1 filament lamp(s) they provide adequate illumination without dazzle in the case of passing beam and good illumination in the case of the driving beam.

6.1.1.          The illumination produced by the headlamp shall be checked on a vertical screen set at a distance of 25 m in front of the headlamp and at right angles to its axis (see annex 6).

6.1.2.          The headlamp shall be checked by means of (a) standard (etalon) filament lamp(s) designed for a rated voltage of 12 V, any selective-yellow filters 6/ being replaced by geometrically identical uncoloured filters with a transmission factor of at least 80%. During the checking of the headlamp the voltage at the terminals of the filament lamp shall be regulated so as to obtain the following characteristics:

6.1.3.          The dimensions determining the position of the filament(s) and the shield inside the standard filament lamp are shown on the relevant data sheet of Regulation No. 37.

6.1.4.          The bulb of the standard filament lamp shall be of such optical shape and quality that it does not cause any reflection or refraction adversely affecting the light distribution. Compliance with this requirement shall be checked by measuring the light distribution obtained when a standard headlamp is fitted with the standard (etalon) filament lamp.

6.2.             The passing beam must produce a sufficiently sharp "cut-off" to permit 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 should be horizontal or within an angle of 15 degrees  above the horizontal.   The headlamp shall be so adjusted that:

6.2.1.          In the case of headlamps designed to meet the requirements of right-hand traffic, the "cut-off" on the left half of the screen7/ 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.          This horizontal part of the "cut-off" is situated on the screen 25 cm below the outline of the horizontal plane passing through the focus of the headlamp (See Annex 6 to this Regulation);

6.2.3.          The screen is in the position indicated in Annex 68/

                   When so adjusted, the headlamp shall, if it is intended to provide a passing beam and a driving beam, comply with the requirements referred to in Paragraphs 6.3 and 6.4 below. If it is intended primarily to provide a passing beam, it need comply only with the requirements referred to in Paragraph 6.39/

                   Where a headlamp so adjusted does not meet the requirements referred to in Paragraphs 6.3 and 6.4, its adjustment may be changed, provided that the axis of the beam or the point of  intersection HV specified Annex 6 to this Regulation is not laterally displaced by more than 1 degrees  (= 44 cm) to the right or left10/.  To facilitate adjustment by    means of the "cut-off", the headlamp may be partially occulted in order to sharpen the "cut-off".

                   If the headlamp is designed solely to provide a driving beam, it shall be so adjusted that the area of maximum illumination is centred on the point of intersection of the lines hh and vv.  Such a headlamp need meet only the requirements referred to in Paragraph 6.5.

                   If, in the case of a headlamp designed to satisfy the requirements of this Regulation with respect to the passing beam only, the focal axis diverges appreciably from the general direction of the beam, lateral adjustment shall be effected to the manner which best satisfies the requirements for illumination at points 75 and 50.

                   The limit of non-adjustment of 1? to the right or left is not incompatible with vertical non-adjustment.  The latter is limited only by the requirements of Paragraph 6.4.

6.3.             The   illumination   produced   on   the   screen   by   the   passing   beam   shall   meet   the requirements of the following Table11/:

                   It is understood that, where the flux of the standard filament lamp used for measurement is other than 450 lumens, the measurements as taken will be corrected proportionally to the rates of the fluxes.  There shall be no lateral variations detrimental to good visibility in any of the zones, I, II, III and IV.

                   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 traffic system.

6.4.             The illumination values in zones "A" and "B" */ as shown in Figure PIC in Annex 6 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:

                   1 + 2 + 3 > 0.3 lux, and  4 + 5 + 6 > 0.6 lux, and 0.7 lux > 7 > 0.1 lux and 0.7 lux > 8 > 0.2 lux

                   These new values shall not be required for headlamps which have been approved before the application date of Supplement 3 to the 01 series of amendments to this Regulation (2 December 1992) nor to the extensions of such approvals.

6.5.             In the case of headlamps with an adjustable reflector the requirements of Paragraphs 6.2 to 6.4 are applicable for each mounting position indicated according to Paragraph 2.1. For verification the following procedure shall be used:

6.5.1.          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 the 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 6.1, 6.2 and/or 6.4;

6.5.2.          With the reflector initially fixed according to Paragraph 6.5.1, the headlamp must meet the relevant photometric requirements of Paragraphs 6.2, 6.3 and 6.4;

6.5.3.          Additional tests are made after the reflector has been moved vertically +/- 2 degrees  or  at least into the maximum position, if less than 2 degrees , 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 75R (75L respectively);

                   driving beam: points HV (percentage of Emax).

6.5.4.          If the applicant has indicated more than one mounting position, the procedure of Paragraphs 6.5.1 to 6.5.3 shall be repeated for all the other positions;

6.5.5.          If the applicant has not asked for special mounting positions, the headlamp shall be aimed for measurements of Paragraphs 6.2 to 6.4 with the headlamps adjusting device in its mean position.  The additional tests of Paragraph 6.5.3 shall be made with the reflector moved into its extreme positions (instead of +/- 2 degrees ) by means of the headlamps adjusting device.

6.6.             Measurements of the illumination produced on the screen by the driving beam shall be taken with the same headlamp adjustment as for measurements under 6.3 above, or, in the case of a headlamp providing a driving beam only, in accordance with the final Paragraph of 6.2.  In the case where more than one light source is used to provide the main beam, the combined functions shall be used to determine the maximum value of the illumination (Emax).

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

                   The point of intersection HV of the lines hh and vv shall be situated within the isolux 90% of maximum illumination.  This maximum value shall not less than 32 lux. Starting from point of intersection HV, horizontally to the right and left, illumination shall be not less than 16 lux up to a distance of 1.125 m and not less than 4 lux up to a distance  of  2.25  m.    (Where  the  flux  of  the  standard  filament  lamp  used  for measurements is other than 700 lumens, the measurements as taken must be corrected proportionally to the ratio of the fluxes.)

6.7.             The screen illumination values mentioned under 6.3 and 6.5 above shall be measured by means of a photo-electric cell, the useful area of which shall be contained within a square of 65 mm side.

7.                GAUGING OF DISCOMFORT

                   The discomfort caused by the passing beam of headlamps shall be gauged.11/

Annex 7 Appendix 2

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 Dr with an opening of 6mm against which the sample stand is placed.    A convergent achromatic lens L2, corrected for spherical aberration, links the diaphragm Dr 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 Dr and the focal length F2 1/ of the lens L2 shall be so chosen that the image of Dr 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:


Annex 7 – Appendix 3

SPRAY TESTING METHOD

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:

                   depsilonlambdataua

                   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 degrees C +/- 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 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 degrees .  Apply force in such a manner that the separation line between the tape and the plate is perpendicular to this force an 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 centimetre of width of the tape.

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 photo metric 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 volts4/.

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 6/

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 degrees 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 7/ 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.8/

8.5.             When so aimed, the unit need, if its approval is sought solely for a passing beam, 9/ 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 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".

8.7.             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:

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

4.3.3.2.       Annex 3, Figure 11, of this Regulation gives examples of arrangements of approval marks corresponding to that case.

B.               TECHNICAL REQUIREMENTS FOR HEADLAMPS 7/

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 vehicle   as to comply with the rules applicable to them.  Such a device need not be fitted on components in which the reflector and the lens cannot be separated provided the use of such components is confined to vehicles on which the headlamp setting can be adjusted by other means.  Where a headlamp providing a driving beam and a headlamp providing a passing 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.  However, this shall not apply to headlamp assemblies whose reflectors are indivisible.  For this type of assembly, the requirements of paragraph 6 shall apply.

5.3.             The components by which the filament lamp(s) is/are fixed to the reflector shall be so made that, even in darkness, the filament lamp(s) can be fixed in no other position but the correct one.8/

                   The filament lamp-holder shall conform to the dimensional characteristics as given in the following data sheets of IEC Publication 61-2:

5.4.             Headlamps designed to satisfy the requirements of both right-hand and 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 precise setting positions, one for right-hand and one for left-hand traffic, shall be possible, and the design shall preclude inadvertently shifting of the headlamp from one position to the other or its setting in an intermediate position.  Where two different setting positions are provided for the filament lamp, the components 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 intended for traffic on only one side of the road.  Conformity with the requirements of this paragraph shall be verified visually and, where necessary, by a test fitting.

5.5.             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 9/ must be so constructed that:

5.5.1.          the device is strong enough to be worked 50,000 times without suffering damage despite the vibration to which it may be subjected in normal use;

5.5.2.          in the case of failure it is possible to obtain the passing beam automatically;

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

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

5.6.             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.

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


6.                ILLUMINATION

6.1.             General provisions

6.1.1.          Headlamps shall be so made that with suitable H1, H2, H3, HB3, HB4, H7, H8, H9, HIR1 and/or HIR2 filament lamps they provide adequate illumination without dazzle in the case of the passing beam and good illumination in the case of the driving beam.

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

6.1.3.          The headlamps shall be checked by means of (a) standard (reference) filament lamp(s) designed for a rated voltage of 12V, any selective-yellow filters10/ being replaced by geometrically identical uncoloured filters with a transmission factor of at least 80%. During the checking of the headlamp the voltage at the terminals of the filament lamp must be regulated so as to obtain the following characteristics:

                   The headlamp shall be deemed satisfactory if the photometric requirements are met with at least one standard (reference) 12V filament lamp which may be supplied with the headlamp.

6.1.4.          The dimensions determining the position of the filament inside the standard filament lamp are shown on the relevant data sheet of Regulation No. 37.

6.1.5.          The bulb of the standard filament lamp must be of such optical shape and quality that it does not cause any reflection or refraction adversely affecting the light distribution. Compliance with this requirement must be checked by measuring the light distribution obtained when a standard headlamp is fitted with the standard (reference) filament lamp.

6.2.             Provisions regarding passing beams

6.2.1.          The passing beam must produce a sufficiently sharp "cut-off" to permit satisfactory adjustment with its aid.  The "cut-off" must be a horizontal straight line on the side opposite to the direction of traffic for which the headlamp is intended; on the other side it must extend neither beyond the broken line HV H1 H4 formed by a straight line HV H1 standing at an angle of 45 degrees to the horizontal and a straight line H1 H4 lying 25cm above the straight line hh, nor beyond the straight line HV H3, inclined at an angle of 15 degrees above the horizontal (see Annex 4).  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.

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 11/ 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 25cm below the line hh (see Annex 4);

6.2.2.3.       the "elbow" of the "cut-off" is on line vv. 12/

6.2.3.          When so aimed, the headlamp need, if its approval is sought solely for a passing beam,13/ comply only with the requirements referred to in paragraphs 6.2.5. to 6.2.7.    below; if it is intended to provide both a passing beam and a driving beam it shall comply with the requirements referred to 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 referred to 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 laterally displaced by more than 1 degrees (=44cm) to the right or left.14/   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 4 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:

                   1+2+3 > 0.3 lux, and

                   4+5+6 > 0.6 lux, and

                   0.7 lux > 7 > 0.1 lux and

                   0.7 lux > 8 > 0.2 lux */

                   These new values shall not be required for headlamps which have been approved before the application date of Supplement 4 to the 04 series of amendments to this Regulation (13 January 1993) nor to the extensions of such approvals.

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.

6.3.             Provisions regarding driving beams

6.3.1.          In 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 proving a driving beam only, it shall be so adjusted that the area of maximum illumination is centred on the point of intersection of the lines hh and vv; such a headlamp need meet only the requirements referred to in paragraph 6.3.

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

6.3.2.1.       the point of intersection (HV) of the lines hh and vv shall be situated within the isolux representing 80% of maximum illumination. This maximum value (EM) shall be not less than 48lux. The maximum value shall in no case exceed 240 lux; moreover, 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 75R (or 75L).

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

                        IM = 0.625 EM

6.3.2.1.2.    the reference mark (IM) indicating this maximum intensity and referred to in paragraph 4.2.2.7. above shall be obtained by means of the formula:

                   this value shall be rounded to whichever is the nearest of the following: 7.5., 10, 12.5, 17.5, 20, 25, 27.5, 30, 37.5, 40, 45, 50.

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

6.4.             In the case of headlamps with an 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 the 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 degrees or    at least into the maximum position, if less than 2 degrees, 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 75R (75L respectively);

                   driving beam:

                        IM and point HV (percentage of IM).

6.4.4.          If the applicant has indicated more than one mounting position, the procedure of paragraphs 6.4.1. to 6.4.3. shall be repeated for all the 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 tests of paragraph 6.4.3. shall be made with the reflector moved into its extreme positions (instead of +/- 2 degrees) by means of the headlamps adjusting device.

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

7.                REQUIREMENTS CONCERNING COLOURED LENSES AND FILTERS

7.1.             Approval may be obtained for headlamps emitting either white or selective-yellow light with a filament lamp. Expressed in CIE thrichromatic coordinates, the corresponding colorimetric characteristics are as follows:

                   Selective-yellow filter (screen or lens)

      Limit towards red               y >0.138 + 0.580 x

      Limit towards green           y<1.29 x - 0.100

      Limit towards white           y>-x + 0.966

      Limit towards

      spectral value                      y<-x + 0.992

Annex 2

VERIFICATION OF CONFORMITY OF PRODUCTION OF HEADLAMPS EQUIPPED WITH H1, H2, H3 HB3, HB4, H7, H8, H9, HIR1 and/or HIR2 FILAMENT LAMPS

1.                GENERAL

1.1.             The conformity requirements shall be considered satisfied from a mechanical and geometric  standpoint,  if  the  differences  do  not  exceed  inevitable  manufacturing deviations within the requirements of this Regulation.

1.2.             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 a standard filament lamp:

1.2.1.          no measured value deviates unfavourably by more than 20% from the values prescribed in this Regulation. For values B50L (or R) and zone III, the maximum unfavourable deviation may be respectively:

                   B50L (or R):        0.2lx equivalent 20%

                                               0.3lx equivalent 30%

                   Zone III:               0.3lx equivalent 20%

                                               0.45lx equivalent 30%

1.2.2.          or if

1.2.2.1.       for the passing beam, the values prescribed in this Regulation are met at HV (with a tolerance of + 0.2lx) and related to that aiming at least one point of each area delimited on the measuring screen (at 25m) by a circle 15cm in radius around points B50L (or R) 1/ (with a tolerance of + 0.1lx ), 75R (or L), 50V, 25R, 25L, and in the entire area of zone IV which is not more than 22.5cm above line 25R and 25L;

1.2.2.2.       and if, for the driving beam, HV being situated within the isolux 0.75 Emax, a tolerance of +20% for maximum values and -20% for minimum values is observed for the photometric  values  at  any  measuring  point  specified  in  paragraph  6.3.2.  of  this Regulation.

1.2.3.          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 1 degrees to the right or left. 14/

1.2.4.          If the results of the tests described above do not meet the requirements, tests on the headlamps shall be repeated using another standard filament lamp.

1.3.             With respect to the verification of the change in vertical position of the cut-off line under the influence of heat, the following procedure shall be applied:

                   One of the sampled headlamps shall be tested according to the procedure described in paragraph 2.1. of Annex 5 after being subjected three consecutive times to the cycle described in paragraph 2.2.2. of Annex 5.

                   The headlamp shall be considered as acceptable if  delta r does not exceed 1.5mrad.

                   If this value exceeds 1.5mrad but is not more than 2.0mrad, a second headlamp shall be subjected to the test after which the mean of the absolute values recorded on both samples shall not exceed 1.5mrad.

1.4.             The chromaticity coordinates shall be complied with when the headlamp is equipped  with a filament lamp set to Standard A colour temperature.

                   The photometric performance of a headlamp emitting selective yellow light when equipped with a colourless filament lamp shall be the values contained in this Regulation multiplied by 0.84.

2.                MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER

                   For each type of headlamp the holder of the approval mark shall carry out at least the following tests, at appropriate intervals. The tests shall be carried out in accordance with the provisions of this Regulation.

                   If any sampling shows non-conformity with regard to the type of test concerned, further samples shall be taken and tested. The manufacturer shall take steps to ensure the conformity of the production concerned.

2.1.             Nature of tests

                   Tests of conformity in this Regulation shall cover the photometric characteristics and the verification of the change in vertical position of the cut-off line under the influence of heat.

2.2.             Methods used in tests

2.2.1.          Tests shall generally be carried out in accordance with the methods set out in this Regulation.

2.2.2.          In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the competent authority responsible for approval tests. The manufacturer is responsible for proving that the applied methods are equivalent to those laid down in this Regulation.

2.2.3.          The application of paragraphs 2.2.1. and 2.2.2. requires regular calibration of test apparatus and its correlation with measurements made by a competent authority.

2.2.4.          In all cases the reference methods shall be those of this Regulation, particularly for the purpose of administrative verification and sampling.

2.3.             Nature of sampling

                   Samples of headlamps shall be selected at random from the production of a uniform batch. A uniform batch means a set of headlamps of the same type, defined according to the production methods of the manufacturer.

                   The assessment shall in general cover series production from individual factories. However, a manufacturer may group together records concerning the same type from several factories, provided these operate under the same quality system and quality management.


2.4.             Measured and recorded photometric characteristics

                   The sampled headlamp shall be subjected to photometric measurements at the points provided for in the Regulation, the reading being limited to points Emax, HV1/ HL, HR2/ in the case of the driving beam, and to points B50L (or R), HV, 50V, 75R (or L) and  25L (or R) in the case of the passing beam (see Figure in Annex 4).

2.5.             Criteria governing acceptability

                   The manufacturer is responsible for carrying out a statistical study of the test results and for  defining,  in  agreement  with  the  competent  authority,  criteria  governing  the acceptability of his products in order to meet the specifications laid down for verification of conformity of products in paragraph 12.1. of this Regulation.

                   The criteria governing the acceptability shall be such that, with a confidence level of 95%, the minimum probability of passing a spot check in accordance with Annex 7 (first sampling) would be 0.95.
