ANNEX 2Minimum requirements for conformity of production control procedures
GENERAL
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. This condition also applies to colour.
With respect to photometric performances, the conformity of mass-produced lamps shall not be contested if, when testing photometric performances of any lamp chosen at random and equipped with a standard (étalon) light source and/or non-replaceable light source(s) and/or LED module(s), as present in the lamp;
No measured value deviates unfavourably by more than 20 per cent from the value prescribed in this Regulation.
For class A, B and D headlamps corresponding to paragraph 5.2. of this Regulation for the values B 50 L (or R) and zone III, the maximum unfavourable deviation may be respectively:
| B 50 L (or R): | 170 cd equivalent 20 per cent |
| 255 cd equivalent 30 per cent | |
| Zone III: | 255 cd equivalent 20 per cent |
| 380 cd equivalent 30 per cent |
For AFS corresponding to paragraph 5.3. of this Regulation no value measured and corrected according to the prescriptions of paragraph 4.6. to this Regulation, deviates unfavourably from the value prescribed in column B of the Tables 17 to 32, if applicable.
For class BS, CS, DS and ES headlamps corresponding to paragraph 5.4. of this Regulation for values in zone I, the maximum unfavourable deviation may be respectively:
| Zone I: | 255 cd equivalent 20 per cent |
| 380 cd equivalent 30 per cent |
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 0,5 degree, to the right or left and not by more than 0,2 degree up and down.
For front fog lamps corresponding to paragraph 5.5. of this Regulation Table 37 shall apply;
or, in case of class A, B or D headlamps corresponding to paragraph 5.2. of this Regulation, if
For the passing-beam, the values prescribed in this Regulation are met at one point within a circle of 0,35 degrees around points:
-
in case of class A or B headlamps B 50 L (or R) (with a tolerance of 85 cd), 75 R (or L), 50 V, 25 R, 25 L, and in the entire area of zone IV which is not more than 0,52 degrees above line 25 R and 25 L;
-
in case of class D headlamps B 50 L (or R) (with a tolerance of 85 cd), 75 R (or L), 50 V, 25 R1, 25 L2, and on segment I;
and if, for the driving beam, HV being situated within the isocandela 0,75 Imax 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 5.1. of this Regulation.
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 0,5 degree to the right or left and not by more than 0,2 degree up or down.
For AFS corresponding to paragraph 5.3. of this Regulation, if the results of the test described above do not meet the requirements, the alignment of the system may be changed in each class, provided that the axis of the beam is not displaced laterally by more than 0,5 degree to the right or left and not by more than 0,2 degree up or down, each independently and with respect to the first aiming.
These provisions do not apply to lighting units as indicated under paragraph 5.3.3.1.1. of this Regulation.
If in the case of a lamp equipped with a replaceable light source the results of the tests described above do not meet the requirements, tests shall be repeated using another standard (étalon) light source.
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 lamps or systems shall be tested according to the procedure described in paragraph 3.1. of Annex 7 after being subjected three consecutive times to the cycle described in paragraph 3.2.2. of Annex 7
A headlamp or system shall be considered as acceptable if Δr does not exceed 1,5 mrad upwards and does not exceed 2,5 mrad downwards.
If this value exceeds 1,5 mrad but is not more than 2,0 mrad upwards or exceeds 2,5 mrad but is not more than 3,0 mrad downwards, 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 upwards and shall not exceed 2,5 mrad downwards.
However, if this value of 1,5 mrad upwards and 2,5 mrad downwards on these two systems is not complied with, another two systems shall be subjected to the same procedure and the value of Δr for each of them shall not exceed 1,5 mrad upwards and shall not exceed 2,5 mrad downwards.
A front fog lamp shall be considered as acceptable if Δr does not exceed 3,0 mrad. If this value exceeds 3,0 mrad but is not more than 4,0 mrad, a second front fog lamp shall be subjected to the test after which the mean of the absolute values recorded on both samples shall not exceed 3,0 mrad.
If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 1.2.3. of Annex 5 or paragraph 3.2. of Annex 6 respectively, one sample shall be tested according to the procedure described in paragraph 2. of Annex 5 or paragraph 4. of Annex 6 respectively.
For cornering lamps
With respect to photometric performances, the conformity of mass-produced lamps shall not be contested if, when testing photometric performances of any lamp chosen at random and equipped with a standard light source, or when the lamps are equipped with non-replaceable light sources (filament light sources or other), and when all measurements are made at 6,75 V, 13,5 V or 28,0 V respectively:
No measured value deviates unfavourably by more than 20 per cent from the values prescribed in this Regulation.
If, in the case of a lamp equipped with a replaceable light source and if results of the test described above do not meet the requirements, tests on lamps shall be repeated using another standard light source.
The chromaticity coordinates shall be complied with when the lamp is equipped with a standard light source, or for lamps equipped with non-replaceable light sources (filament light sources or other), when the colorimetric characteristics are verified with the light source present in the lamp.
In the case of non-replaceable filament light source(s) or light source module(s) equipped with non-replaceable filament light sources, at any conformity of production check:
the holder of the approval mark shall demonstrate the use in normal production and show the identification of the non-replaceable filament light source(s) as indicated in the type approval documentation;
in the case where doubt exists in respect to compliance of the non-replaceable filament light source(s) with lifetime requirements and/or, in the case of colour coated filament light sources, with colour endurance requirements, as specified in paragraph 4.11 of IEC 60809, Edition 3, conformity shall be checked as specified in paragraph 4.11 of IEC 60809, Edition 3.
The chromaticity coordinates shall be complied with.
MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER
For each type of lamp 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.
Nature of tests
Tests of conformity in this Regulation shall cover the photometric and colorimetric characteristics and the verification of the change in vertical position of the cut-off line under the influence of heat.
Methods used in tests
Tests shall generally be carried out in accordance with the methods set out in this Regulation.
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.
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.
In all cases the reference methods shall be those of this Regulation, particularly for the purpose of administrative verification and sampling.
Nature of sampling
Samples of lamps shall be selected at random from the production of a uniform batch. A uniform batch means a set of lamps 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.
Measured and recorded photometric characteristics
The sampled devices shall be subjected to photometric measurements at the points provided for in the Regulation, the reading being limited:

The RID or part(s) thereof shall be mounted on a goniometer with a fixed horizontal axis and moveable axis perpendicular to the fixed horizontal axis.
The luminous intensity values shall be determined by means of a photoreceptor contained within a square of 65 mm side and, except for cornering lamps, set up to a distance of at least 25 m forward of the centre of reference of each headlamp or lighting unit perpendicular to the measurement axis from the origin of the goniometer. The point HV is the centre-point of the coordinate system with a vertical polar axis. Line h is the horizontal through HV (see Figure A4-1).
The angular co-ordinates are specified in deg on a sphere with a vertical polar axis according to the gonio-photometer as defined in Figure A4-1.
During photometric measurements, stray reflections should be avoided by appropriate masking.
Any equivalent photometric method is acceptable, if the accordingly applicable correlation is observed.
An aiming screen shall be used and may be located at a shorter distance than that of the photoreceptor.
The RID or part(s) thereof shall be so aimed before starting the measurements that the position of the "cut-off" complies with the relevant requirements for the specific function in paragraph 5 to this Regulation.
In case of AFS:
Any offset of the centre of reference of each lighting unit, with respect to the goniometer rotation axes, should be avoided. This applies especially to the vertical direction and to lighting units producing a "cut-off".
The photometric requirements for each single measuring point (angular position) of a lighting function or mode as specified in this Regulation apply to half of the sum of the respective measured values from all lighting units of the system applied for this function or mode, or, from all lighting units as indicated in the respective requirement;
However in those cases where a provision is specified for one side only, the division by the factor of 2 does not apply. These cases are: paragraphs 5.3.2.5.2., 5.3.2.8.1., 5.1.3.5., 5.1.3.6., 5.3.3.4.1., 5.3.5.1. of this Regulation, and note 4 of Table 9.
The lighting units of the system shall be measured individually; however, simultaneous measurements may be performed on two or more lighting units of an installation unit, being equipped with the same light source types with respect to their power supply (either power controlled or not), if they are sized and situated such, that their illuminating surfaces are completely contained in a rectangle of not more than 300 mm in horizontal extend and not more than 150 mm vertical extend, and, if a common centre of reference is specified by the manufacturer.
The system shall prior to the subsequent test procedures be set to the neutral state.
The system or part(s) thereof shall be so aimed before starting the measurements that the position of the "cut–off" complies with the requirements indicated in the Table 10. Parts of a system measured individually and having no "cut-off" shall be installed on the goniometer under the conditions (mounting position) specified by the applicant.
In case of Cornering lamps
When photometric measurements are taken, stray reflections shall be avoided by appropriate masking.
In the event that the results of measurements are challenged, measurements shall be taken in such a way as to meet the following requirements:
The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable;
The measuring equipment shall be such that the angle subtended by the receiver from the reference centre of the light is between 10′ and 1°;
The intensity requirement for a particular direction of observation shall be satisfied if the required intensity is obtained in a direction deviating by not more than one quarter of a degree from the direction of observation.

ANNEX 5Aiming procedure, instrumental verification of the "cut-off" for asymmetric passing-beams
VISUAL AIMING PROCEDURE
The luminous intensity distribution of a principal passing-beam headlamp or of at least one lighting unit for a class C passing beam of an AFS in its neutral state shall incorporate a "cut-off" (see Figure A5-I), which enables the headlamp to be adjusted correctly for the photometric measurements and for the aiming on the vehicle.
The "cut-off" shall provide:
-
For right hand traffic beams:
-
A straight "horizontal part" towards the left;
-
A raised "elbow - shoulder" part towards the right.
-
-
For left hand traffic beams:
-
A straight "horizontal part" towards the right;
-
A raised "elbow - shoulder" part towards the left.
-
In each case the "elbow-shoulder" part shall have a sharp edge.
The headlamp or AFS shall be visually aimed by means of the "cut-off" (see Figure A5-I) as follows. The aiming shall be carried out using a flat vertical screen set up at a distance of 10 m or 25 m (as indicated in item 9 of Annex 1) forward of the headlamp or AFS and at right angles to the H-V axis as shown in Annex 4. The 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.
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 (0,57 degrees) below the H-H line;
The scales are different for vertical and horizontal lines.
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:
-
Above the line 0,2° D its "shoulder" shall not exceed the line A to the left;
-
The line 0,2° D or below its "shoulder" should cross the line A; and
-
The kink of the "elbow" is basically located within +/-0,5 degrees to the left or right of the V-V line;
or
For left hand traffic from left to right and shall be horizontally positioned after its movement so that:
-
Above the line 0,2° D its "shoulder" shall not exceed the line A to the right;
-
On the line 0,2° or below its "shoulder" cross the line A; and
-
The kink of the "elbow" should be primarily on the V-V line;
Where a headlamp or AFS so aimed does not meet the requirements set out in paragraphs this Regulation 5.2. to 5.4. of this Regulation respectively, its alignment may be changed, provided that the axis of the beam is not displaced:
Horizontally from line A by more than:
-
0,5° to the left or 0,75° to the right, for right hand traffic; or
-
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.
If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 1.2.3., the instrumental method of paragraph 2. 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.
When so aimed, a headlamp, if its approval is sought solely for provision of a passing-beam9, need comply only with the requirements set out in paragraphs 5.2. to 5.4. of this Regulation; if it is intended to provide both a passing-beam and a driving-beam, it shall comply with the requirements set out in paragraphs 5.1. to 5.4. of this Regulation.
INSTRUMENTAL VERIFICATION OF THE "CUT-OFF" LINE FOR ASYMMETRIC PASSING-BEAMS
General
In the case where paragraph 1.2.4. applies, the quality of the "cut-off" line shall be tested according to the requirements set out in paragraph 2.2. and the instrumental vertical and horizontal adjustment of the beam shall be performed according to the requirements set out in paragraph 2.3.
Before carrying out the measurement of the quality of "cut-off", and the instrumental aiming procedure, a visual pre-aim in accordance with paragraphs 1.2.1. and 1.2.2. is required.
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:
-
10 m with a detector having a diameter of approximately 10 mm; or
-
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 to 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 at least one set of measurements complies with the requirements of paragraphs 2.2.1. to 2.2.3.
Not more than one "cut-off" shall be visible(1)
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 Eβ - log E(β + 0,1°)) where β = the vertical position in degrees and E = the illumination on the aiming screen.
The value of G shall not be less than 0,13 (minimum sharpness) and not greater than 0,40 (maximum sharpness).
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 A5-II).
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:
The maximum vertical distance between the inflection points determined shall not exceed 0,2°.
(d2 (log E) / dβ2 = 0).
Vertical and horizontal adjustment
If the "cut-off" complies with the quality requirements of paragraph 2.2. the beam adjustment may be performed instrumentally.
The scales are different for vertical and horizontal lines.
Vertical adjustment
Moving upward from below the line B (see Figure A5-III), 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) / dβ2 = 0) is determined and positioned on the line B situated one per cent below H-H.
Horizontal adjustment
The applicant shall specify one of the following horizontal aim methods:
-
The "0,2 D line" method (see Figure A5-III).
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 Eβ - 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.
The scales are different for vertical and horizontal lines.
-
The "3 line" method (see Figure A5-IV)
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 Eβ – 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.
The scales are different for vertical and horizontal lines.
