bulb this test shall be left out if the approval is also given to the same type of filament lamp emitting white light.

3.9.5. A headlamp shall be deemed to be a standard headlamp if:

3.9.5.1. it satisfies the pertinent conditions of approval;

3.9.5.2. it has an effective diameter of not less than 160mm;

3.9.5.3. with a standard filament lamp it produces at the various points and in the various zones specified for the headlamp type concerned, illumination equal to:

        3.9.5.3.1.  not more than 90% of the maximum limits and

3.9.5.3.2. not less than 120% of the minimum limits prescribed for the headlamp type concerned.

3.10. Standard filament lamps

Standard filament lamps for photometric tests of headlamps and light-signalling appliances are specified on the relevant data sheets of annex 1. Standard filament lamps shall have colourless bulbs (except for amber filament lamps) and be specified for only one rated voltage.

4. CONFORMITY OF PRODUCTION

4.1. Filament lamps approved to this Regulation shall be so manufactured as to conform to the type approved by meeting the inscriptions and technical requirements set forth in paragraph 3 above and annexes 1, 3 and 4 to this Regulation.
4.2. In order to verify that the requirements of paragraph 4.1. are met, suitable controls of the production shall be carried out.

4.3. The holder of the approval shall in particular:

4.3.1. ensure existence of procedures for the effective control of the quality of products,
4.3.2. have access to the control equipment necessary for checking the conformity to each approved type,
4.3.3. 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,
4.3.4. analyse the results of each type of test, applying criteria of annex 7, in order to verify and ensure the stability of the product characteristics making allowance for variation of an industrial production,
4.3.5. ensure that for each type of filament lamp, at least the tests prescribed in annex 6 to this Regulation are carried out,
4.3.6. 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.
4.4. The competent authority which has granted type-approval may at any time verify the conformity control methods applicable to each production unit.
4.4.1. In every inspection, the test books and production survey records shall be presented to the visiting inspector.
4.4.2. The inspector may take samples at random which will be tested in the manufacturer's laboratory. The minimum number of samples may be determined according to the results of
