EVS-EN ISO 10447:2015

This International Standard specifies the procedures and recommended tooling to be used for peel and chisel testing of resistance spot and projection welds. This International Standard applies to welds made in two or more sheets in the thickness range of 0,5 mm to 3,0 mm.
The aim of these tests is to determine
— weld size and failure type when welds are destructively tested, and
— verification of welds by non-destructive chisel tests.
NOTE The preferred method of peel testing seam welds (mechanized peel testing) is covered in ISO 14270.
