       Limit towards spectral value  y ≤- x + 0.992

       which can also be expressed as follows:

       dominant wave-length  575 - 585 n m

       purity factor   0.90 - 0.98

       The transmission factor must be  ≥ 0.78

       The transmission factor shall be determined by using a light source with a colour temperature of 2,854 degrees K. (Corresponding to illuminant A of the International

       Commission on Illumination (CIE)) .

       8.2. The filter must be part of the headlamp, and must be attached to it in such a way that the user cannot remove it either inadvertently or intentionally, with ordinary tools.

       8.3. Observation concerning colour

       Since any approval under this Regulation is granted, pursuant to paragraph 8.l. above, for a type of headlamp emitting either colourless light or selective-yellow light; article 3 of the Agreement to which the Regulation is annexed shall not prevent the Contracting Parties from prohibiting headlamps emitting a beam of uncoloured or selective-yellow light on vehicles registered by them.

       9. CONFORMITY OF PRODUCTION

       9.1. Headlamps approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraphs 7 and 8.

       9.2. In order to verify that the requirements of paragraph 9.1. are met, suitable controls of the production shall be carried out.

       9.3. The holder of the approval shall in particular:

       9.3.1. ensure the existence of procedures for the effective control of the quality of products;

       9.3.2. have access to the control equipment necessary for checking the conformity to each approved type;

       9.3.3. ensure that data of test results are recorded and that related documents shall remain available for a period to be determined in accordance with the administrative service;

       9.3.4. analyze the results of each type of test in order to verify and ensure the stability of the product characteristics, making allowance for variation of an industrial production;

       9.3.5. ensure that, for each type of product, at least the tests prescribed in Annex 4 to this Regulation are carried out;

       9.3.6. ensure that any collecting of samples giving evidence of non-conformity with the type of test considered shall give rise to another sampling and another test. All the necessary steps shall be taken to re-establish the conformity of the corresponding production.

       9.4. The competent authority which has granted type approval may at any time verify the conformity control methods applicable to each production unit.

       9.4.1. In every inspection, the test books and production survey records shall be presented to the visiting inspector.

       9.4.2. The inspector may take samples at random to be tested in the manufacturer's laboratory.  The minimum number of samples may be determined in the light of the results of the manufacturer's own checks.
