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% RH.
4. TEST PIECES
Before the test, the sample roll of adhesive tape shall be conditioned for 24 hours in the
specified atmosphere (see Paragraph 3 above).
Five test pieces each 400 mm 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
300 mm/s, then apply them within 15 seconds 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 25 mm 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 300 mm/s ± 30 mm/s and record the force required.
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.

is assumed not to provide sufficient linearity or sharpness for performing visual
adjustment. In this case the quality of "cut-off" shall be tested instrumentally for compliance
with requirements as follows.
4. MEASUREMENT OF THE QUALITY OF "CUT-OFF"
4.1. Measurements shall be performed by vertically scanning through the horizontal part of the
"cut-off" line in angular steps not exceeding 0.05°

or at a measurement distance of 25 m and a detector with a diameter of approximately
30 mm.
The measurement of the "cut-off" quality shall be considered acceptable if the requirements of
the Paragraph 4.1.2 of this Annex shall comply with at least one measurement at 10 m or
25 m.
The measuring distance at which the test was determined shall be noted down in
Paragraph 9, Annex 1 "Communication form" of this Regulation.
The scanning is performed from its lower position upwards through the "cut-off" line along the
vertical lines at -3° to -1.5° and +1.5° to +3° from the V-V Line. When so measured, the
quality of the "cut-off" line shall meet the following requirements:

G = (log E - log E )
is called the sharpness factor G of the "cut-off" line. The value of G shall not be less than
0.13 for Class B and 0.08 for Classes A, C, D and E.
4.1.3. Linearity: the part of the "cut-off" line which serves for vertical adjustment shall be horizontal
from 3° L to 3° R of the V-V Line. This requirement is deemed to be met if the vertical
positions of the inflection points according to Paragraph 3.2 above at 3° left and right of the
V-V Line do not differ by more than 0.2° for Class B and 0.3° for Classes A, C, D and E
headlamps from the nominal position at the V-V Line.
5. INSTRUMENTAL VERTICAL ADJUSTMENT
if the "cut-off" line complies with the above quality requirements, the vertical beam
adjustment can be performed instrumentally. For this purpose the inflection point where
d (log E) / dv = 0 is positioned on the V-V Line in its nominal position below the H-H Line.
The movement for measuring and adjusting the "cut-off" line shall be upwards from below the
nominal position.

ANNEX 11
VOLTAGE MARKINGS
This marking must be placed on the main
body of each headlamp containing only
gas-discharge light sources and ballast, and on
each external part of the ballast.
The ballast(s) is(are) designed for a ** Volts
network system.
This marking must be placed on the
main body of each headlamp containing at
least one gas-discharge light source and
ballast.
The ballast(s) is(are) designed for a **
Volts network system.
None of the filament lamps which the
headlamp contains is designed for a 24 V
network system.

3.3. Ageing
Upon the request of the applicant the LED module shall be operated for 48 h and cooled
down to ambient temperature before starting the tests as specified in this Regulation.
4. SPECIFIC SPECIFICATIONS AND TESTS
4.1. Colour Rendering
4.1.1. Red Content
In addition to measurements as described in Paragraph 7. of this Regulation, the minimum
red content of the light of a LED module or headlamp incorporating LED module(s) tested at
50 V shall be such that:
k
=


E
E
( λ) V ( λ)
( λ) V ( λ)


≥ 0.05
where:
E (λ) (unit: W)
V(λ) (unit: 1)
is the spectral distribution of the irradiance;
is the spectral luminous efficiency;
(λ)
(unit: nm) is the wavelength.
This value shall be calculated using intervals of one nanometre.

4.3. Temperature Stability
4.3.1. Illuminance
4.3.1.1. A photometric measurement of the headlamp shall be made after 1 minute of operation for
the specific function at the test point specified below. For these measurements, the aim can
be approximate but must be maintained for before and after ratio measurements.
Test points to be measured:
Passing beam 50 V
Driving beam H − V
4.3.1.2. The lamp shall continue operation until photometric stability has occurred. The moment at
which the photometry is stable is defined as the point in time at which the variation of the
photometric value is less than 3% within any 15 minute period. After stability has occurred,
aim for complete photometry shall be performed in accordance with requirements of specific
device. Photometer the lamp at all test points required for the specific device.
4.3.1.3. Calculate the ratio between the photometric test point value determined in
Paragraph 4.3.1.1. and the point value determined in Paragraph 4.3.1.2.
4.3.1.4. Once stability of photometry has been achieved, apply the ratio calculated above to each of
the remainder of the test points to create a new photometric table that describes the
complete photometry based on one minute of operation.
4.3.1.5. The illuminance values, measured after one minute and after photometric stability has
occurred, shall comply with the minimum and maximum requirements.
4.3.2. Colour
The colour of the light emitted measured after one minute and measured after photometric
stability has been obtained, as described in Paragraph 4.3.1.2. of this Annex, shall both be
within the required colour boundaries.
