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.
              2.                                     With respect to photometric performance, the conformity of mass-produced side-marker lamps shall not be contested if, when testing photometric performances of any side-marker lamp chosen at random and equipped with a standard light source, or when the side-marker 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.                               No measured value deviates unfavourably by more than 20 per cent from the values prescribed in this Regulation.
                  2.                               If, in the case of a side-marker lamp equipped with a replaceable light source and if results of the test described above do not meet the requirements, tests on side-marker lamps shall be repeated using another standard light source.
                  3.                               Side-marker lamps with apparent defects are disregarded.
              3.                                     The chromaticity coordinates shall be complied with when the side-marker lamp is equipped with a standard light source, or for side-marker lamps equipped with non-replaceable light sources (filament lamps or other), when the colorimetric characteristics are verified with the light source present in the side-marker lamp.
          2. First sampling
         In the first sampling four side-marker 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 side-marker lamps shall not be contested if the deviation of the measured values of the side-marker lamps in the unfavourable directions are:
2.1.1.1.                        Sample A
A1:  one side-marker lamp                0 per cent
     one side-marker lamp not more than  20 per cent

A2:  both side-marker 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 side-marker 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 side-marker 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 side-marker lamps are:
2.2.1.1.              Sample A
A3:  one side-marker lamp not more than  20 per cent
     one side-marker 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 side-marker lamp more than      0 per cent
     but not more than                   20 per cent
     one
