Scope

This document specifies the dimensions, the method of sampling, the preparation of the test specimens and the conditions for performing the tensile creep test perpendicular to the weld in order to determine the long-term tensile welding factor. A tensile creep test may be used in conjunction with other tests (e.g. bend test, tensile test, macrographic examination, …) to assess the performance of welded assemblies made from thermoplastics materials. The test is applicable to welded assemblies made from thermoplastics materials, filled or unfilled such as tubes and fittings, sheets, plates and profiles, but not reinforced, irrespective of the welding process used.
