MINIMUM REQUIREMENTS FOR CONFORMITY OF PRODUCTION CONTROL PROCEDURES

1.	GENERAL

0.3 lx equivalent 30 per cent

Zone III:	0.3 lx equivalent 20 per cent

0.45 lx equivalent 30 per cent

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 + 0.2 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), 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;

- 20 per cent for minimum values is observed for the photometric values at any measuring point specified in paragraph 6.6. 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° to the right or left. 9/

__________

1/ Letters in brackets refer to headlamps intended for left-hand traffic.

9/ See the corresponding footnote in the text of the Regulation.

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 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 r does not exceed 1.5 mrad.

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

1.4.	The chromaticity coordinates shall be complied with.

The photometric performance of a headlamp emitting selective yellow light 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.

2.2.2.	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, HV 1/, HL, HR 2/ in the case of the driving beam, and to points B 50 L (or R), HV, 75 R (or L) and 25 L (or R) in the case of the passing beam (see figure in annex 6).

2/	HL and HR: points on "hh" located at 1.125 m to the left and to the right of point HV respectively.

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 9.1. of this Regulation.

The criteria governing the acceptability shall be such that, with a confidence level of 95 per cent, the minimum probability of passing a spot check in accordance with annex 8 (first sampling) would be 0.95."

Annex 4, paragraph 3, should be deleted.

Add a new Annex 8, to read:
