the conformity of mass-produced direction indicators shall not be contested if, when testing photometric performances of any direction indicator chosen at random and equipped with a standard filament lamp, or when the direction indicators are equipped with non-replaceable light sources (filament lamps or other), and when all measurements are made at 6.75 V, 13.5 V or 28.0 V respectively:

       1.2.1. no measured value deviates unfavourably by more than 20% from the values prescribed in this Regulation.

       1.2.2. If, in the case of a direction indicator equipped with a replaceable light source and if results of the test described above do not meet the requirements, tests on direction indicators shall be repeated using another standard filament lamp.

       1.3. The chromaticity coordinates shall be complied with when the direction indicator is equipped with a standard filament lamp, or for direction indicators equipped with non- replaceable light sources (filament lamps or other), when the colorimetric characteristics are verified with the light source present in the direction indicator.

       2. MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER

        For each type of direction indicator 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 and colorimetric 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. 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 direction indicators shall be selected at random from the production of a uniform batch.  A uniform batch means a set of direction indicators 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
