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 per cent from the values prescribed in this Regulation.

       1.2.2. If, in the case of a lamp equipped with a replaceable light source(s) and if results of the test described above do not meet the requirements, tests on lamps shall be repeated using another standard light source.

       1.2.3. Lamps with apparent defects are disregarded.

       1.3. 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.

       2. First sampling

In the first sampling four lamps 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 lamps shall not be contested if the deviation of the measured values of the lamps in the unfavourable directions are:

       2.1.1.1. Sample A

A1:  one lamp                0 per cent
     one lamp not more than  20 per cent
A2:  both lamps more than    0 per cent
     but not more than       20 per cent
     go to sample B

       2.1.1.2. Sample B

B1:  both lamps  0 per cent

       2.1.2. Or, if the conditions of paragraph 1.2.2. above for sample A are fulfilled.

       2.2. The conformity is contested

       2.2.1. Following the sampling procedure shown in Figure 1 of this annex the conformity of mass-produced lamps shall be contested and the manufacturer requested to make his production meet the requirements (alignment) if the deviations of the measured values of the lamps are:

       2.2.1.1. Sample A

A3:  one lamp not more than  20 per cent
     one lamp more than      20 per cent
     but not more than       30 per cent

       2.2.1.2. Sample B

B2:  in the case of A2
     one lamp more than      0 per cent
     but not more than       20 per cent
     one lamp not more than  20 per cent
B3:  in the case of A2
     one lamp                0 per cent
     one lamp more than      20 per cent
     but not more than       30 per cent

       2.2.2. Or, if the conditions of paragraph 1.2.2. above for sample A are not fulfilled.

       2.3. Approval withdrawn

Conformity shall be contested and paragraph 14. of this Regulation applied if, following the sampling procedure in Figure 1 of this annex, the deviations of the measured values of the lamps are:

       2.3.1. Sample A

A4:  one lamp not more than  20 per cent
     one lamp more than      30
