fold back the free end of the tape at 90 degrees. Apply force in such a manner that the separation line between the tape and the plate is perpendicular to this force and perpendicular to the plate.
Pull to unstick at a speed of 300 mm/s +/- 30 mm/s and record the force required.
6.                                          RESULTS
The five values obtained shall be arranged in order and the median value taken as the result of the measurement. This value shall be expressed in Newtons per centimetre of width of the tape.

       MINIMUM REQUIREMENTS FOR SAMPLING BY AN INSPECTOR

          1. GENERAL
              1.                                     The conformity 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 headlamps shall not be contested if, when testing photometric performances of any headlamp chosen at random and equipped with a standard filament lamp;
                  1.                               no measured value deviates unfavourably by more than 20 % from the values prescribed in this Regulation. For zone III the maximum deviation may be respectively:
0.3 lux equivalent 20 %
0.45 lux equivalent 30 %
1.2.2.                              and if, for the driving beam, HV being situated within the isolux 0.75 Emax, a tolerance of + 20 % for maximum values and - 20 % for minimum values is observed for the photometric values at any measuring point specified in Annex 3, paragraphs 4.3 and 4.4 of this Regulation.
1.2.3.                              If the results of the tests described above do not meet the requirements, tests on the headlamp shall be repeated using another standard filament lamp.
1.2.4.                              Headlamps with apparent defects are disregarded.
1.3.                                    The chromaticity coordinates shall be complied with when the headlamp is equipped with a filament lamp set to Standard A colour temperature.
The photometric performance of a headlamp emitting selective yellow light when equipped with a colourless filament lamp shall be 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
A1:  one headlamp                0%
     one headlamp not more than  20%
A2:  both headlamps more than    0%
     but not more than           20%

go to sample B
2.1.1.2.                        sample B
B1:  both headlamps  0 %

2.2.                                    The conformity is contested
2.2.1.                              Following
