       1.2.4. Headlamps with apparent defects are disregarded.

       1.2.5. The reference mark is disregarded.

       1.3. The photometric performance of a headlamp emitting selective yellow light shall be the values contained in this Regulation multiplied by 0.84.

       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 deviation of the measured values of the headlamps in the unfavourable directions are:

       2.1.1.1. sample A

       An it be all of the same

       2.1.1.2. sample B

        Bl:  both headlamps      0 %

       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 %

         one headlamp more than     20 %

         but not more than      30 %

       2.2.1.2. sample B

       B2: in the case of A2

         one headlamp more than     0 %

         but not more than      20 %

         one headlamp not more than     20 %

       B3: in the case of A2

         one headlamp       0 %

         one headlamp more than     20 %

         but not more than      30 %

       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 Approval withdrawn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 12 applied if, following the sampling procedure 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 %

         one headlamp more than     30 %

       A5: both headlamps more than     20 %

       2.3.2. sample B

       B4: in the case of A2

         one headlamp more than     0 %

         but not more than      20 %

         one headlamp more than     20 %

       B5: in the case of A2

         both headlamps more than     20 %

       B6: in the case of A2

         one headlamp       0 %

         one headlamp more than     30 %

       2.3.3. or if the conditions of paragraph 1.2.2. for samples A and B are not fulfilled.

       3. REPEATED SAMPLING

       In the cases of A3, B2, B3 a repeated sampling, third sample C of two headlamps and fourth sample D of two headlamps, selected from stock manufactured after alignment, is necessary within two months time after the notification.

       3.1. The conformity is not contested
