About this training

Summary

This document specifies the dimensions and the method for sampling and preparing test specimens, together with the conditions for carrying out the bend test.
The result of the test is also influenced by the deformation behaviour of the tested material, the kind of welding process and the geometry of the sample.
The test is applicable to plate and tube butt jointed assemblies made from thermoplastic materials filled or unfilled, but not reinforced, irrespective of the welding process used. It is not applicable to assemblies with a wall thickness < 3 mm.
