        1.2.4. If the results of the tests described above do not meet the requirements, tests shall be repeated using another standard filament lamp.

1.2.5. Headlamps with apparent defects are disregarded.

1.2.6. The reference mark is disregarded.

2. FIRST SAMPLING

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

2.1.1.1. sample A

A1:  one headlamp 0 per cent
  one headlamp not more than 20 per cent

A2:  both headlamps more than  0 per cent
  but  not more than 20 per cent
  go to sample B

2.1.1.2. sample B

        B1:  both headlamps 0 per cent

2.1.2. or if the conditions of paragraph 1.2.2. 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 headlamps shall be contested and the manufacturer requested to make his production meet the requirements (alignment) if the deviations of the measured values of the headlamps are:

2.2.1.1. sample A

A3: one headlamp not more than 20 per cent
 one headlamp 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 headlamp more than  0 per cent

        but not more than 20 per cent

        one headlamp not more than 20 per cent

        B3: in the case of A2

        one headlamp  0 per cent
        one headlamp more than  20 per cent
        but not more than 30 per cent

        2.2.2. or if the conditions of paragraph 1.2.2. for sample A are not fulfilled.

2.3. Approval withdrawn

        Conformity shall be contested and paragraph 11 applied if, following the sampling procedure shown in Figure 1 of this annex, the deviations of the measured values of the headlamps are:

2.3.1. sample A

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

        A5: Both headlamps more than  20 per cent

2.3.2. sample B

        B4: in the case of A2
         one headlamp more than 0 per cent
         but not more than 20 per cent
         one headlamp more than 20 per cent

        B5: in the case of A2
         both headlamps more than 20 per cent

        B6: in the case of A2
         one headlamp  0 per cent
         one headlamp more
