标准范围

ISO 14271:2017规定了电阻点焊、凸焊和缝焊蚀刻横截面的硬度测试程序。硬度试验的目的是确定厚度为0.5 mm至6 mm的薄板焊缝的熔核、热影响区和黑色或有色金属母材在低作用力或显微硬度范围内的维氏硬度。

ISO 14271:2017 specifies the procedures for the hardness testing of etched cross-sections of resistance spot, projection, and seam welds.The aim of the hardness tests is to determine the Vickers hardness, in the low-force or microhardness range, of the weld nugget, the heat affected zone, and parent material in ferrous or non-ferrous metals for welds made in sheets of thickness 0,5 mm to 6 mm.
