B.   TECHNICAL REQUIREMENTS FOR HEADLAMPS (5)

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 principal passing beam and a headlamp providing a driving beam, each equipped with its own filament lamp or LED module(s), 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:






5.3.1.


filament lamp(s) approved according to Regulation No 37. Any filament lamp covered by Regulation No 37 may be used, provided that no restriction on the use is made in Regulation No 37 and its series of amendments in force at the time of application for type approval.






5.3.1.1.


The design of the device shall be such that the filament lamp can be fixed in no other position but the correct one (6).










5.3.1.2.


The filament lamp holder shall conform to the characteristics given in IEC Publication 60061. The holder data sheet relevant to the category of filament lamp used, applies.














5.3.2.


and/or LED module(s):






5.3.2.1.


electronic light source control gear(s), if applicable, shall be considered to be part of the headlamp; they may be part of the LED module(s);










5.3.2.2.


the headlamp, if equipped with LED modules, and the LED module(s) themselves shall comply with the relevant requirements specified in Annex 10 of this Regulation. The compliance with the requirements shall be tested.










5.3.2.3.


The total objective luminous flux of all LED modules producing the principal passing beam and measured as described in paragraph 5 of Annex 10 shall be equal or greater than 1 000 lumens.








5.4.   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 or LED module(s) producing the principal passing beam at a given angle/position 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 or LED module(s) producing the principal passing beam, the components for attaching the filament lamp or LED module(s) producing the principal passing beam to the reflector must be so designed and made that, in each of its two settings, this filament lamp or LED module(s) 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.
5.5.   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.
5.6.   Light transmitting components made of plastic material shall be tested according to the requirements of Annex 6.
5.7.   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:






5.7.1.


the device is robust enough to withstand 50 000 operations under normal conditions of use. In order to verify compliance with this requirement, the technical service responsible for approval tests may:






(a)


require the applicant to supply the equipment necessary to perform the test;










(b)


forego the test if the headlamp presented by the applicant is accompanied by a test report, issued by a technical service responsible for approval tests for headlamps of the same construction (assembly), confirming compliance with this requirement.














5.7.2.


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 3 lux shall be fulfilled in test point 25 V (VV line, D 75 cm).
When performing the tests to verify compliance with these requirements, the technical service responsible for approval tests shall refer to the instructions supplied by the applicant.










5.7.3.


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










5.7.4.


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




5.8.   Illumination configuration for different traffic conditions








5.8.1.


In the case of headlamps designed to meet the requirements of traffic moving on one side of the road (either right or left) only, appropriate measures shall be taken to prevent discomfort to road-users in a country where traffic moves on the side of the road opposite to that of the country for which the headlamp was designed (7). Such measures may be:






(a)


occulting a part of the outer headlamp lens area;










(b)


downward movement of the beam. Horizontal movement is allowed;










(c)


any other measure to remove or reduce the asymmetrical part of the beam.
















5.8.2.


Following the application of this (these) measure(s) the following requirements regarding illumination shall be met with the adjustment left unchanged compared to that for the original traffic direction:






5.8.2.1.


Passing beam designed for right-hand traffic and adapted to left-hand traffic:






at 0,86D-1,72L


at least 3 lux




at 0,57U-3,43R


not more than 1,0 lux














5.8.2.2.


Passing beam designed for left-hand traffic and adapted to right-hand traffic:






at 0,86D-1.72R


at least 3 lux




at 0,57U-3,43L


not more than 1,0 lux












5.9.   In case of a passing beam headlamp incorporating a light source or LED module(s) producing the principal passing beam and having a total objective luminous flux which exceeds 2 000 lumen a reference shall be made in item 9 of the communication form in Annex 1. The objective luminous flux of LED modules shall be measured as described in paragraph 5 of Annex 10.
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. Bend lighting may be produced by activating one additional filament light source or one or more LED module(s) being part of the passing beam headlamp.












6.1.2.


The illumination produced by the headlamp shall be determined by means of a flat vertical screen set up 25 m forward of the headlamp, at right angles to its axes as shown in Annex 3 to this Regulation; the test screen shall be sufficiently wide to allow examination and adjustment of the ‘cut-off’ of the passing beam over at least 5° on either side of the V-V line.












6.1.3.


Apart from 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 as indicated for each filament lamp at the relevant data sheet of Regulation No 37. The headlamp shall be considered acceptable if it meets the requirements of paragraph 6 with at least one standard (étalon) filament lamp, which may be submitted with the headlamp.












6.1.4.


LED module(s) shall be measured at 6,3 V, 13,2 V or 28,0 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.
The values obtained by the LED module(s) shall be multiplied by a factor of 0,7 prior to check for compliance.












6.1.5.


In the case of headlamps equipped with LED module(s) and filament lamps, the part of the headlamp with filament lamp(s) shall be tested according to paragraph 6.1.3 and the part of the headlamp with LED module(s) shall be evaluated according to the provisions of paragraph 6.1.4 and then added to the previous result obtained from the filament lamp(s) tested.




6.2.   Provisions concerning passing beams








6.2.1.


The luminous intensity distribution of the principal passing beam headlamp shall incorporate a ‘cut-off’ (see figure 1), which enables the headlamp to be adjusted correctly for the photometric measurements and for the aiming on the vehicle.
The ‘cut-off’ shall provide:






(a)


For right hand traffic beams:






(i)


a straight ‘horizontal part’ towards the left;










(ii)


a raised ‘elbow-shoulder’ part towards the right.














(b)


For left hand traffic beams:






(i)


a straight ‘horizontal part’ towards the right;










(ii)


a raised ‘elbow-shoulder’ part towards the left.








In each case the ‘elbow-shoulder’ part shall have a sharp edge.












6.2.2.


The headlamp shall be visually aimed by means of the ‘cut-off’ (see figure 1) as follows:






6.2.2.1.


for vertical adjustment: the horizontal part of the ‘cut-off’ is moved upward from below line B and adjusted to its nominal position one per cent (25 cm) below the H-H line;

Figure 1




Note: The scales are different for vertical and horizontal lines.










6.2.2.2.


for horizontal adjustment: the ‘elbow-shoulder’ part of the ‘cut-off’ shall be moved:
for right hand traffic from right to left and shall be horizontally positioned after its movement so that:






(a)


above the line 0,2° D its ‘shoulder’ shall not exceed the line A to the left;










(b)


the the line 0,2° D or below its ‘shoulder’ should cross the line A; and










(c)


the kink of the ‘elbow’ should be primarily on the V-V line;




or
for left hand traffic from left to right and shall be horizontally positioned after its movement so that:






(a)


above the line 0,2 D its ‘shoulder’ shall not exceed the line A to the right;










(b)


on the line 0,2° or below its ‘shoulder’ cross the line A; and










(c)


the kink of the ‘elbow’ should be primarily on the V-V line;














6.2.2.3.


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:
Horizontally from line A by more than:






(a)


0,5° to the left or 0,75° to the right, for right hand traffic; or










(b)


0,5° to the right or 0,75° to the left, for left hand traffic; and




vertically not more than 0,25° up or down from line B.










6.2.2.4.


If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 6.2.2.3 above, the instrumental method of Annex 9, paragraphs 2 and 3 shall be applied to test compliance with the required minimum quality of the ‘cut-off’ and to perform the vertical and horizontal adjustment of the beam.
















6.2.3.


When so aimed, the headlamp, if its approval is sought solely for provision of a passing beam (8), need comply only with the requirements set out in paragraphs 6.2.4 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 6.2.4 to 6.2.6 and 6.3.

6.2.7.


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 LED module(s) producing the principal passing beam or of the filament lamp, meet the requirements set forth above for the corresponding direction of traffic.












6.2.8.


The requirements in paragraph 6.2.4 above shall also apply to headlamps designed to provide bend lighting and/or that include the additional light source or LED module(s) referred to in paragraph 6.2.9.2. 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°.






6.2.8.1.


If bend lighting is obtained by:






6.2.8.1.1.


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 re-aimed horizontally, e.g. by means of a goniometer;










6.2.8.1.2.


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;










6.2.8.1.3.


means of one additional filament light source or one or more LED module(s) without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with this light source or LED module(s) activated.




















6.2.9.


Only one filament light source or one or more LED module(s) are permitted for the principal passing beam. Additional light sources or LED modules are permitted only as follows (see Annex 10):






6.2.9.1.


one additional light source according to Regulation No 37 or one or more additional LED module(s) may be used inside the passing beam headlamp to contribute to bend lighting;










6.2.9.2.


one additional light source according to Regulation No 37 and/or one or more LED module(s), inside the passing beam headlamp, may be used for the purposes of generating infrared radiation. It/they shall only be activated at the same time as the principal light source or LED module(s). In the event that the principal light source or (one of) the principal LED module(s) fails, this additional light source and/or LED module(s) shall be automatically switched off;










6.2.9.3.


in the event of failure of an additional filament light source or one or more additional LED module(s), 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 6.2.4 to 6.2.6 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 H-H and V-V; such a headlamp need meet only the requirements referred to in paragraph 6.3. Where more than one light source is used to provide the driving beam, the combined functions shall be used to determine the maximum value of the illumination (EM).












6.3.2.


Irrespective of the type of light source (LED module(s) or filament light source(s)) used to produce the principal passing beam, several light sources:






(a)


either filament light sources listed in Regulation No 37; or










(b)


LED module(s) may be used for each individual 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:





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 realised 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:







principal 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 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 6.2.4 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.




8.   GAUGING OF DISCOMFORT
The discomfort caused by the passing beam of headlamps shall be gauged (10).
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 or the LED module(s) as submitted with the headlamp, which has (have) been aged for at least one hour, the headlamp shall be operated on the principal 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 ΔrI = | r3 – r60 | recorded on the headlamp is not more than 1,0 mrad (ΔrI ≤ 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 stabilise 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, except for a daytime running lamp. 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 filaments and/or LED module(s) be simultaneously lit when headlamp flashing is used, this shall not be considered as being normal use of the filaments and/or LED module(s).

(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 200-300 cP 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.

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

B 50 L (or R)


:


0,2 lx equivalent 20 per cent
0,3 lx equivalent 30 per cent




Zone III


:


0,3 lx equivalent 20 per cent
0,45 lx equivalent 30 per cent

or if






1.2.2.1.


for the passing beam, the values prescribed in this Regulation are met at HV (with a tolerance of + 0,2 lx) and related to that aiming at least one point of each area delimited on the measuring screen (at 25 m) by a circle 15 cm in radius around points B 50 L (or R) (1) (with a tolerance of + 0,1 lx), 75 R (or L), 50 V, 25 R, 25 L, and in the entire area of zone IV which is not more than 22,5 cm above line 25 R and 25 L;










1.2.2.2.


and if, for the driving beam, HV being situated within the isolux 0,75 Emax, a tolerance of + 20 per cent for maximum values and – 20 per cent for minimum values is observed for the photometric values at any measuring point specified in paragraph 6.3.2 of this Regulation.














1.2.3.


If the results of the test 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° to the right or left.










1.2.4.


If in the case of a lamp equipped with a replaceable filament light source the results of the tests described above do not meet the requirements, tests shall be repeated using another standard (étalon) 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 4 after being subjected three consecutive times to the cycle described in paragraph 2.2.2 of Annex 4.










 


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










 


If this value exceeds 1,5 mrad but is not more than 2,0 mrad, a second sample shall be subjected to the test after which the mean of the absolute values recorded on both samples shall not exceed 1,5 mrad.
















1.4.


If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 6.2.2.3 of this Regulation, one sample shall be tested according to the procedure described in paragraphs 2 and 3 of Annex 9.




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 provision of this Regulation.

1.   EQUIPMENT (see figure)
The beam of a collimator K with a half divergence β/2 = 17,4 × 10-4 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 αο/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:

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 9

Instrumental verification of the ‘cut-off’ for passing beam headlamps

1.   GENERAL
In the case where paragraph 6.2.2.4 of this Regulation applies, the quality of the ‘cut-off’ shall be tested according to the requirements set out in paragraph 2 below and the instrumental vertical and horizontal adjustment of the beam shall be performed according to the requirements set out in paragraph 3 below.
Before carrying out the measurement of the quality of ‘cut-off’ and the instrumental aiming procedure, a visual pre-aim in accordance with paragraphs 6.2.2.1 and 6.2.2.2 of this Regulation is required.
2.   MEASUREMENT OF THE QUALITY OF THE ‘CUT-OFF’
To determine the minimum sharpness, measurements shall be performed by vertically scanning through the horizontal part of the ‘cut-off’ in angular steps of 0,05° at either a measurement distance of:






(a)


10 m with a detector having a diameter of approximately 10 mm; or










(b)


25 m with a detector having a diameter of approximately 30 mm.




The measuring distance at which the test was carried out shall be recorded in item 9 of the communication form (see Annex 1 of this Regulation).
To determine the maximum sharpness, measurements shall be performed by vertically scanning through the horizontal part of the ‘cut-off’ in angular steps of 0,05° exclusively at a measurement distance of 25 m and with a detector having a diameter of approximately 30 mm.
The ‘cut-off’ quality shall be considered acceptable if the requirements of paragraph 2.1 to 2.3 below comply with at least one set of measurements.
2.1.   Not more than one ‘cut-off’ shall be visible (1)

2.2.   Sharpness of ‘cut-off’
The sharpness factor G is determined by scanning vertically through the horizontal part of the ‘cut-off’ at 2,5° from the V-V where:
G = (log Εβ – log E(β + 0,1°)) where β = the vertical position in degrees.
The value of G shall not be less than 0,13 (minimum sharpness) and not greater than 0,40 (maximum sharpness).
2.3.   Linearity
The part of the horizontal ‘cut-off’ that serves for vertical adjustment shall be horizontal between 1,5° and 3,5° from the V-V line (see figure 1).
The inflection points of the ‘cut-off’ gradient at the vertical lines at 1,5°, 2,5° and 3,5° shall be determined by the equation:
(d2 (log E)/dβ2 = 0)
The maximum vertical distance between the inflection points determined shall not exceed 0,2°.
3.   VERTICAL AND HORIZONTAL ADJUSTMENT
If the ‘cut-off’ complies with the quality requirements of paragraph 2 of this Annex, the beam adjustment may be performed instrumentally.

Figure 1


Measurement of ‘cut-off’ quality












Note:


The scales are different for vertical and horizontal lines.




3.1.   Vertical adjustment
Moving upward from below the line B (see figure 2 below), a vertical scan is carried out through the horizontal part of the ‘cut-off’ at 2,5° from V-V. The inflection point (where d2 (log E)/dv2 = 0) is determined and positioned on the line B situated one per cent below H-H.
3.2.   Horizontal adjustment
The applicant shall specify one of the following horizontal aim methods:






(a)


The ‘0,2 D line’ method (see figure 2 below).
A single horizontal line at 0,2° D shall be scanned from 5° left to 5° right after the lamp has been aimed vertically. The maximum gradient ‘G’ determined using the formula G = (log Εβ – log E(β + 0,1°)) where β is the horizontal position in degrees, shall not be less than 0,08.
The inflection point found on the 0,2 D line shall be positioned on the line A.

Figure 2


Instrumental vertical and horizontal adjustment — horizontal line scan method












Note:


The scales are different for vertical and horizontal lines.














(b)


The ‘3 line’ method (see figure 3)
Three vertical lines shall be scanned from 2° D to 2° U at 1°R, 2°R, and 3°R after the lamp has been aimed vertically. The respective maximum gradients ‘G’ determined using the formula:
G = (log Εβ – log E(β + 0,1°))
where β is the vertical position in degrees, shall not be less than 0,08. The inflection points found on the three lines shall be used to derive a straight line. The intersection of this line and the line B found while performing vertical aim shall be placed on the V line.
