BS EN 17271:2019 pdf free.Plastics – Poly(vinyl chloride) (PVC) based profiles – Determination of the peel strength of profiles laminated with foils.
The length of the free path between the laminated sample and the clamping jaws (clamping distance lo) 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.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 x (20土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土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 x 20 mm in the direction of the specimen.BS EN 17271 pdf download.
