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 and quality management.

       2.4. Measured and recorded photometric characteristics

        The sampled direction indicator shall be subjected to photometric measurements for the minimum values at the points listed in Annex 4, and the chromaticity coordinates listed in Annex 5, provided for in the Regulation.

       2.5. Criteria governing acceptability

        The manufacturer is responsible for carrying out a statistical study of the test results and for defining, in agreement with the competent 4 authority, 4 criteria governing the cceptability of his products in order to meet the specifications laid down for verification of conformity of products in paragraph 10.1. of this Regulation.

        The criteria governing the acceptability shall be such that, with a confidence level of 95%, the minimum probability of passing a spot check in accordance with Annex 7 (first sampling) would be 0.95.

       Annex 7

       MINIMUM REQUIREMENTS FOR SAMPLING BY AN INSPECTOR

       1. GENERAL

       1.1. The conformity requirements shall be considered satisfied from a mechanical and a geometric standpoint, in accordance with the requirements of this Regulation, if any, if the differences do not exceed inevitable manufacturing deviations.

       1.2. With respect to photometric performance, 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 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:

       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.

       1.2.3. Direction indicators with apparent defects are disregarded.

       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. FIRST SAMPLING

        In the first sampling four direction indicators are selected at random.  The first sample of two is marked A, the second sample of two is marked B.

       2.1. The conformity is not contested

       2.1.1. Following the sampling procedure shown in Figure 1 of this Annex the conformity of mass-produced direction indicators shall not
