标准范围

This document specifies test specimens and procedures for performing constant load amplitude fatigue 
tests on multi-spot-welded and multi-axial specimens in the thickness range from 0,5 mm to 5 mm 
at room temperature and a relative humidity of maximum 80 %. The applicability of this document 
to larger thicknesses can be limited by mechanical properties such as yield strength and formability 
of the specimen material. The thickness range for advanced high strength steels (AHSS) is generally 
below 3,0 mm. Greater thicknesses apply for aluminium alloys, for example.
Depending on the specimen used, it is possible from the results to evaluate the fatigue behaviour of:
— spot welds subjected to defined uniform load distribution;
— spot welds subjected to defined non-uniform load distribution;
— spot welds subjected to different defined combinations of shear-, peel- and normal-tension loads; and
— the tested specimen.
