In all other cases, the test sample shall be subjected to the following cycle test for
each, the mode(s) of Class C passing beam, the Class V passing beam, the Class E
passing beam and the Class W passing beam, whatever is provided or partly provided
by the test sample, for the same (equally divided) part of the time specified in
Paragraph 1.1.:

mode for straight road conditions;
Five minutes, same passing beam mode lit as before and, additionally, all light

After having reached the said (equally divided) part of the time specified in
Paragraph 1.1., the above cycle test shall be performed with the second, third and
fourth class of passing beam, if applicable, in the above order.

Except for points B50L, a 10% discrepancy between the photometric characteristics and the
values measured prior to the test is permissible including the tolerances of the photometric
procedure. The value measured at point B50L shall not exceed the photometric value
measured prior to the test by more than 170cd.

operation.
The measurement of the variation in the cut-off line position as described above shall be
carried out by any method giving acceptable accuracy and reproducible results.
2.2. Test Results
2.2.1. The result expressed in milliradians (mrad) shall be considered as acceptable for a passing
beam test sample, when the absolute value Δ r = ⏐ r - r ⏐ recorded on the headlamp is not

Paragraph 1.1.1.2.);
After this period of one hour, the headlamp type shall be considered as acceptable if the
absolute value Δ r measured on this sample meets the requirements in Paragraph 2.2.1
above.

2.2.2.2. Application of the Test Mixture
2.2.2.3. Cleaning
2.2.3. Results
Soak a piece of cotton cloth (as per ISO 105) until saturation with the mixture defined in
Paragraph 2.2.2.1. above and, within 10s, apply it for 10min to the outer face of the sample at
a pressure of 50N/cm , corresponding to an effort of 100N applied on a test surface of
14 × 14mm.
During this 10min period, the cloth pad shall be soaked again with the mixture so that the
composition of the liquid applied is continuously identical with that of the test mixture
prescribed.
During the period of application, it is permissible to compensate the pressure applied to the
sample in order to prevent it from causing cracks.
At the end of the application of the test mixture, the samples shall be dried in the open air and
then washed with the solution described in Paragraph 2.3. (Resistance to detergents and
hydrocarbons) at 23°C ± 5°C. Afterwards the samples shall be carefully rinsed with distilled

scratches, scaling or deformation.
The UV-resistance testing of internal materials to light source radiation is not necessary if light
sources according to Regulation No. 37 and/or low-UV-type gas discharge light sources

ANNEX 6 − APPENDIX 4
ADHESIVE TAPE ADHERENCE TEST
1. PURPOSE
This method allows to determine under standard conditions the linear force of adhesion of an
adhesive tape to a glass plate.
2. PRINCIPLE
Measurement of the force necessary to unstick an adhesive tape from a glass plate at an angle
of 90°.
3. SPECIFIED ATMOSPHERIC CONDITIONS
The ambient conditions shall be at 23°C ± 5°C and 65 ± 15% relative humidity.
4. TEST PIECES
Before the test, the sample roll of adhesive tape shall be conditioned for 24h in the specified
atmosphere (see Paragraph 3. above).
Five test pieces each 400mm long shall be tested from each roll. These test pieces shall be
taken from the roll after the first three turns were discarded.
5. PROCEDURE
The test shall be performed under the ambient conditions specified in Paragraph 3.
Take the five test pieces while unrolling the tape radially at a speed of approximately 300mm/s,
then apply them within 15s in the following manner:
Apply the tape to the glass plate progressively with a slight length-wise rubbing movement of the
finger, without excessive pressure, in such a manner as to leave no air bubble between the tape
and the glass plate.
Leave the assembly in the specified atmospheric conditions for 10 minutes.
Unstick about 25mm of the test piece from the plate in a plane perpendicular to the axis of 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 300mm/s ± 30mm/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 Newton per centimetre of width of the tape.
