of paragraphs 2.2.1. and 2.2.2. requires regular calibration of test apparatus and its correlation with measurement made by a Competent Authority.

       2.2.4. In all cases the reference methods shall be those of this Regulation, particular for the purpose of administrative verification and sampling.
       2.3. Nature of sampling

       Samples of headlamps shall be selected at random from the production of a uniform batch.  A uniform batch means a set of headlamps 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 and quality management.

       2.4. Measured and recorded photometric characteristics

       The sampled headlamps shall be subjected to photometric measurements at the points provided for in the Regulation, the reading being limited at the points:

          2.4.1. For Class A headlamps:  HV, LH, RH, 12.5L and 12.5R

       2.4.2. For Class B headlamps:  Emax, HV [41]/, in the case of the driving beam, and to the points HV, 50R, 50L, in the case of the passing beam.

       2.4.3. For Class C and D headlamps:  Emax, HV 1/, in the case of the driving beam, and to the points HV, 0.86D/3.5R, 0.86D/3.5L, in the case of the passing beam.

          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 Authority, criteria governing acceptability of his products in order to meet the specification laid down for verification of conformity of products in paragraph 9.1. of this Regulation.

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