from a photometric, geometrical, visual and electrical standpoint if the specified tolerances for production filament lamps in the relevant data sheet of annex 1 and the relevant data sheet for the caps are met.

            2.                                                       MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER

            For each type of filament lamp the manufacturer or the holder of the approval mark shall carry out tests, in accordance with the provisions of this Regulation, at appropriate intervals.

 2.1. Nature of tests
            Tests of conformity of these specifications shall cover their photometrical, geometrical and optical characteristics.

 2.2. Methods used in tests
            2.2.1. Tests shall generally be carried out in accordance with the methods set out in this Regulation.
            2.2.2. The application of paragraph 2.2.1. requires regular calibration of test apparatus and its correlation with measurements made by a competent authority.

 2.3. Nature of sampling
            Samples of filament lamps shall be selected at random from the production of a uniform batch. A uniform batch means a set of filament lamps of the same type, defined according to the production methods of the manufacturer.

 2.4. Inspected and recorded characteristics
            The filament lamps shall be inspected and test results recorded following the grouping of characteristics as listed in annex 7, table 1.

 2.5. Criteria governing acceptability
            The manufacturer or the holder of the approval is responsible for carrying out a statistical study of the test results in order to meet the specifications laid down for verification of conformity of products in paragraph 4.1 of this Regulation. Compliance shall be assured if the level of acceptable non-compliance per grouping of characteristics given in table 1 of annex 7 is not exceeded. This means that the number of lamps not complying with the requirement for any grouping of characteristics of any filament lamp type does not exceed the qualifying limits in the relevant table 2, 3 or 4 of annex 7.

            Note: Each individual filament lamp requirement shall be considered as a characteristic.
