NBN EN 12814-7:2002

This standard specifies the dimensions, the method of sampling, the preparation of the test specimens and the conditions for performing the tensile test with waisted test specimens in order to determine the tensile energy welding factor. A tensile test with waisted specimens may be used in conjunction with other tests (e.g. bend, tensile, tensile creep, macro...) to assess the performance of welded assemblies, made from thermoplastics materials.
