This standard specifies the instruments and equipment, samples, test procedures and test reports for the cross tensile test method of resistance spot welding and projection welding lap joints of metallic materials. This standard applies to resistance welding joints with a metal plate thickness of 0.5 mm to 5.0 mm and a maximum solder joint diameter of 7t and less than 12mm (t is the plate thickness, and when the plate thickness is different, it is the thickness of the thinner plate). t
