Annex 5
Minimum requirements for conformity of production control procedures

4.                                          General
4.1.                                    The conformity requirements shall be considered satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Regulation.
4.2.                                    With respect to photometric performances, the conformity of mass-produced lamps shall not be contested if, when testing photometric performances of any lamp chosen at random and equipped with a standard light source, or when the lamps 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:
4.2.1.                              No measured value deviates unfavourably by more than 20 per cent from the values prescribed in this Regulation.
4.2.2.                              If, in the case of a lamp equipped with a replaceable light source and if results of the test described above do not meet the requirements, tests on lamps shall be repeated using another standard light source.
4.3.                                    The chromaticity coordinates shall be complied with when the lamp is equipped with a standard light source, or for lamps equipped with non-replaceable light sources (filament lamps or other), when the colorimetric characteristics are verified with the light source present in the lamp.
5.                                          Minimum requirements for verification of conformity by the manufacturer
For each type of lamp 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.
5.1.                                    Nature of tests
Tests of conformity in this Regulation shall cover the photometric and colorimetric characteristics.
5.2.                                    Methods used in tests
5.2.1.                              Tests shall generally be carried out in accordance with the methods set out in this Regulation.
5.2.2.                              In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the Type Approval Authority responsible for approval tests.  The manufacturer is responsible for proving that the applied methods are equivalent to those laid down in this Regulation.
5.2.3.                              The application of paragraphs 2.2.1. and 2.2.2. above requires regular calibration of test apparatus and its correlation with measurements made by a Type Approval Authority.
5.2.4.                              In all cases the reference methods shall be those of this Regulation, particularly for the purpose of administrative verification and sampling.
5.3.                                    Nature of sampling
Samples of lamps shall be selected at random from the production of a uniform batch.  A uniform batch means a set of lamps of
