标准摘要
[中文适用范围]： 本国际标准规定了重叠板中单点、对接接头和压痕投影焊缝的试样尺寸和试验程序，适用于厚度为0.5 mm至3 mm的任何金属材料。对于直径在5√t到7√t之间的焊缝，由于测试试样的宽度是根据直径≤5√t的焊缝设计的，因此使用推荐的测试试样尺寸时，获得的剥离强度值可能低于预期。 [外文原描述]： ISO 14270:2016 specifies specimen dimensions and a testing procedure for mechanized peel testing of single spot, seam and embossed 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). For welds of diameter between 5√ t and 7√ t , the peel strength values obtained may be lower than expected when using the recommended test specimen dimensions because the test specimen width is designed for welds of diameter of 5√ t or less. The object of mechanized peel testing is to determine the peel strength that the test specimen can sustain.
