NBN EN 12814-4:2001

This standard specifies the dimensions, the method of sampling, the preparation of the test specimens, and also the conditions for performing the peel test perpendicular to the weld in order to determine the peel resistance and the failure behaviour.
A peel test may be used in conjunction with other tests (e.g. tensile creep, macro...) to assess the performance of welded assemblies, made from thermoplastics materials.
Peel tests are applicable to overlap welded assemblies made from thermoplastics materials, irrespective of the welding process used.
