Resistance welding. Destructive testing of welds. Specimen dimensions and procedure for cross tension testing of resistance spot and embossed projection welds1 Scope This International Standard specifies specimen dimensions and a testing procedure for the cross tension testing of spot and projection welds in overlapping sheets in any metallic material of thickness 0,5 mm to 3 mm, where the welds have a maximum diameter of 7t (where t is the sheet thickness in mm). The object of cross tension testing is to determine the tensile force that the test specimen can sustain.
