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

       1.1. 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 difference do not exceed inevitable manufacturing deviations.

       1.2. 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:

       1.2.1. no measured value deviates unfavorable by more than 20% from the values prescribed in this Regulation.

       For values B 50 L (or R) and Zone III the maximum deviation may be respectively:              B 50 L (or R):              0.2   1x equivalent 20%

            0.3   1x equivalent 30%

          Zone III  0.3   1x equivalent 20%

            0.45   1x equivalent 30%

       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 1x) and related to the that aiming at least one points of each area delimited on the measuring screen (with a tolerance of 0.1 1x), 75 R (or L), 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 E max , a tolerance of + 20% for maximum values and - 20 % for minimum values is observed for the photometric values at any measuring point specified in paragraph 8.10. of this

       1.2.3. If the results of the tests described above do not meet the requirements, the alignment of the headlamp may be changed, provided that axis of the beam is not displaces laterally by more than 1 degrees to the right or left. [10/]

       1.2.4. Headlamps with apparent defects are disregarded.

       1.2.5. The reference mark is disregarded.

       1.3. The chromaticity coordinates shall be complied with.

       The photometric performance of a headlamp emitting selective yellow light shall be the values contained in this Regulation 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 samples of two is marked B.

       2.1. The conformity is not contested
