ISO 14272:2016规定了厚度为0.5 mm至3 mm的任何金属材料的重叠板材中点焊和凸焊的交叉拉伸测试的试样尺寸和测试程序,其中焊缝的最大直径为7√t(其中t是以mm为单位的板材厚度)。
交叉拉伸试验的目的是确定试样所能承受的拉伸力。
ISO 14272:2016 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 7√t (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.
