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 (RH).
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 under the ambient conditions specified in Paragraph 3.
Take the five test pieces while unrolling the tape radially at a speed of approximately 300ms,
then apply them within 15s in the following manner:
Apply the tape to the glass plate progressively with a slight lengthwise 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 10min.
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.
6. RESULTS
Pull to unstick at a speed of 300ms ± 30ms and record the force required.
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.

2. FIRST SAMPLING

4. CHANGE OF THE VERTICAL POSITION OF THE CUT-OFF LINE
With respect to the verification of the change in vertical positions of the cut-off line under the
influence of heat, the following procedure shall be applied:
One of the headlamps of Sample A after sampling procedure in Figure 1 of this Annex shall
be tested according to the procedure described in Paragraph 2.1 of Annex 5 after being
subjected three consecutive times to the cycle described in Paragraph 2.2.2 of Annex 5.
The headlamp shall be considered as acceptable if Δr does not exceed 1.5mrad.
If this value exceeds 1.5mrad but is not more than 2.0mrad, the second headlamp of
Sample A shall be subjected to the test after which the mean of the absolute values recorded
in both samples shall not exceed 1.5mrad.
