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

       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 are:

       3.1.1.1. sample C

       Cl: one headlamp       0 %

         one headlamp not more than     20 %

       C2: both headlamps more than     0 %

         but not more than      20 %

       go to sample D

       3.1.1.2. sample D

       Dl: in the case of C2

         both headlamps      0 %

       3.1.2. or if the conditions of paragraph 1.2.2. for sample C are fulfilled.

       3.2. The conformity is contested

       3.2.1. 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:

       3.2.1.1. sample D

       D2: in the case of C2

         one headlamp more than     0 %

         but not more than      20 %

         one headlamp not more than     20 %

       3.2.1.2. or if the conditions of paragraph 1.2.2. for sample C are not fulfilled:

       3.3. Approval withdrawn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:

       3.3.1. sample C

       C3: one headlamp not more than     20 %

         one headlamp more than     20 %

       C4: both headlamps more than     20 %

       3.3.2. sample D

       D3: in the case of C2

         one headlamp 0 or more than     0 %

         one headlamp    more than     20 %

       3.3.3. or if the conditions of paragraph 1.2.2. for samples C and D are not fulfilled.

       4. CHANGE OF THE VERTICAL POSITION OF THE CUT-OFF LINE

       With respect to the verification of the change in vertical positions of the cut-off line under the influence of heat, the following procedure shall be applied:

       One of the headlamps of sample A after sampling procedure in Figure 1 of this annex shall be tested according to the procedure described in paragraph 2.1. of annex 6 after being subjected three consecutive times to the cycle described in paragraph 2.2.2. of annex 6.

       The headlamp shall be considered as acceptable if delta r does not exceed 1.5 mrad.

       If this value exceeds 1.5 mrad but is not more than 2.0 mrad, the second headlamp of sample A shall be subjected to the test after which the mean of the absolute values recorded in both samples shall not
