       Annex 16

       TEST PROCEDURE FOR CLASS IB DEVICES

Retro-reflecting devices of Class IB shall be tested according to the test procedures specified in Annex 4, following the chronological order of tests given in annex 12, with the exception of the test according to annex 8, paragraph 1, which for Class IB devices may be replaced by the test specified in annex 8, paragraph 1.2.

       Annex 17

       MINIMUM REQUIREMENTS FOR CONFORMITY OF PRODUCTION CONTROL PROCEDURES

       1. GENERAL

       1.1. 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.

       1.2. With respect to photometric performances, the conformity of mass-produced retro- reflectors shall not be contested if, when testing photometric performances of any retro- reflector chosen at random no measured value deviates unfavourably by more than 20% from the minimum values prescribed in this Regulation.

       1.3. The chromaticity coordinates shall be complied with.

       2. MINIMUM REQUIREMENTS FOR VERIFICATION OF CONFORMITY BY THE MANUFACTURER

       For each type of retro-reflector 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 and the resistance to penetration of water.

       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 retro-reflectors shall be selected at random from the production of a uniform batch. A uniform batch means a set of retro-reflectors 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
