the test piece.  Fix the plate and fold back the free end of the tape at 90°. 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 a 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

       1.1. The conformity requirements shall be considered satisfied from a mechanical and a geometrical standpoint in accordance with the requirements of this Regulation, if any, if the differences do not exceed inevitable manufacturing deviations.  This condition also applies to colour.

       1.2. With respect to photometric performances, 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:

       1.2.1. Class A headlamps: no measured value deviates unfavourably by more than 20 per cent from the value prescribed in this Regulation.

       1.2.2 Class B, C and D headlamps:

       1.2.2.1. no measured value deviates unfavourably by more than 20 per cent from the value prescribed in this Regulation.  For values in zone III for Class B headlamp, zone I for Class C and D headlamp, the maximum unfavorable deviation may be respectively:

       0.3  lux equivalent 20 per cent
       0.45  lux equivalent 30 per cent

       1.2.2.2. and if for the driving beam, HV being situated within the isolux 0.75 Emax, a tolerance of + 20 per cent for maximum values and - 20 per cent for minimum values is observed for the photometric values at any measuring point specified in paragraphs 6.2.3.2. and 6.3.2.2. of this Regulation.

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

       1.2.4. Headlamps with apparent defects are disregarded.

       1.3. If, however, for a series of samples vertical adjustment cannot be performed repeatedly to the required position within the allowed tolerances, the quality of cut-off shall be tested on one of the headlamps from the series of samples, according to the procedure described in Annex 9, paragraphs 2. and 4.

       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
