a uniform batch.  A uniform batch means a set of gas-discharge light sources of the same type, defined according to the production methods of the manufacturer.

       2.4. Inspected and recorded characteristics

       The gas-discharge light sources shall be inspected and test results recorded following the grouping of characteristics as listed in annex 7, table 1.

       2.5. Criteria governing acceptability

       The manufacturer or the holder of the approval is responsible for carrying out a statistical study of the test results in order to meet the specifications laid down for verification of conformity of products in paragraph 4.1. of this Regulation.   Compliance shall be assured if the level of acceptable non- compliance per grouping of characteristics given in table 1 of annex 7 is not exceeded.  This means that the number of gas-discharge light sources not complying with the requirement for any grouping of characteristics of any gas-discharge light source type does not exceed the qualifying limits in the relevant tables 2, 3 or 4 of annex 7.

       Note: Each individual gas-discharge light source requirement shall be considered as a characteristic.
