Testing of welded joints in thermoplastics semi-finished products - Part 3: Tensile creep test

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 longterm 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.
