4 Principle
The peel strength of a profile laminated with a foil is determined by measuring the peel force
perpendicularly to the surface of the profile, under specified conditions.
5 Apparatus and materials
5.1 Tensile testing machine, conforming to EN ISO 7500-1, class 1.
5.2 Peel strength device, capable of applying a force to the free end of a foil separated from a
laminated profile, using a tensile testing machine, comprising two rolls as shown in Figure 3, or
comparable device.

The length of the free path between the laminated sample and the clamping jaws (clamping distance l )
shall be between 25 mm and 30 mm.
5.3 Masking tape, olefin- or PVC-based self-adhesive tape or siliconised-paper having a thickness
of ≤ 80 µm and a width of ≥ 50 mm. Other materials may be used if they do not influence the test results,
the masking tape shall not stick to the laminated foil.
In case that the masking tape cannot be removed from the laminated foil, due to the glue, this shall be
mentioned in the test report.
NOTE: The masking tape is only needed for preparation of the test specimens according to 6.2 (not 6.3).
5.4 Cutting ruler (template), at least 100 mm long.
5.5 Cutter/blade, sharp enough to provide a clean cut in order to protect against fraying the edge of
the foil.
6 Preparation of the test specimens
6.1 General
Prepare five test specimens according to one of the methods described below.
NOTE Method 1 is used when special sample preparation is applied. Method 2 is usually applied to ready-to-
use profiles, when special sample preparation cannot be achieved.
6.2 Method 1
The masking tape is applied on the profile before or during the lamination in the traditional way, e.g.
each 200 mm as indicated in Figure 4.
Key
1 profile section with masking tape
2 profile section without masking tape
Figure 4 —Example of test specimen preparation
Cut off the laminated surface of the laminated profile or use the laminated profile in full size.
Cut the separated laminated surface or laminated profile into sections of at least 150 mm long.
Place a template that is at least 100 mm × (20 ± 1) mm lengthways on the laminated surface in the
middle of these sections.
Using a blade cut through the laminated foil along both longitudinal edges of the template to obtain
specimens with a width of (20 ± 1) mm.
6.3 Method 2
Cut off the laminated surface of the laminated profile or use the laminated profile in full size.
Cut the separated laminated surface or laminated profile into sections of at least 100 mm long and
50 mm wide.
Place a template that is at least 100 mm × (20 ± 1) mm lengthways on the laminated surface in the
middle of these sections.
Using a blade cut through the laminated foil along both longitudinal edges of the template to obtain
specimens with a width of (20 ± 1) mm.
From the rear, mill the PVC profile wall in the middle of the specimen and across its longitudinal axis to
a residual thickness of 0,1 mm to 0,2 mm. When generating this transfer line be careful not to cut into
the PVC too deeply so as to avoid damaging the foil on the adhesive side.
Then mill away the entire back profile wall of the specimen in the longitudinal direction along the two
cuts made along the template at a distance of 20 mm from one end of the specimen as far as the
transverse line.
Break off the approximatively 0,1 mm to 0,2 mm thick material by bending the milled strip of at least
50 mm × 20 mm in the direction of the specimen.
7 Conditioning
Condition the test specimens at (23 ± 5) °C for at least 2 h before testing.
The test specimens should only be tested after the adhesive system has achieved sufficient strength.
NOTE Usually the time to achieve sufficient strength of the adhes
