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

       3.1.1. 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 are:

       3.1.1.1. sample C

       C1: 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

       D1: 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 mark his production meet the requirements (alignment) if the deviations If 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 Approval withdrawn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 13 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 %

       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 5 after being subjected three consecutive times to the cycle described in paragraph 2.2.2. of annex 5.

       The headlamps 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 exceed 1.5 mrad.

       However, if this value of 1.5 mrad on sample A is not complied with, the
