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. no measured value deviates unfavourably by more than 20 per cent from the value prescribed in this Regulation.  For values B 50 L (or R) and zone III, the maximum unfavourable deviation may be respectively:

B 50 L (or R):  0.2 lx equivalent 20 per cent
     0.3 lx equivalent 30 per cent
Zone III  0.3 lx equivalent 20 per cent
    0.45 lx equivalent 30 per cent

1.2.2. or if

        1.2.2.1. for the passing beam, the values prescribed in this Regulation are met at HV (with a tolerance of 0.2 lx) and related to that aiming at least one point of each area delimited on the measuring screen (at 25 m) by a circle 15 cm in radius around points B 50 L (or R) (with a tolerance of 0.1 lx), 75 R (or L), 50 V, 25 R, 25 L, and in the entire area of zone IV which is not more than 22.5 cm above line 25 R and 25 L;

        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 paragraph 6.3.2. of this Regulation.  The reference mark is disregarded.

        1.2.3. If the results of the test described above do not meet the requirements, the alignment of the headlamp may be changed, provided that the axis of the beam is not displaced laterally by more than 1° to the right or left. [26]/

        1.2.4. If the results of the tests described above do not meet the requirements, tests shall
