BS EN ISO 14271:2017规定了电阻蚀刻横截面的硬度测试程序 点焊、凸焊和缝焊。硬度试验的目的是在低作用力或显微硬度下测定维氏硬度 黑色金属或有色金属中焊核、热影响区和母材的范围 对于厚度为0.5mm至6mm的薄板焊缝。交叉引用:ISO 17677-1:2009版1ISO 6507-4:2005版1ISO 6507-2:2005版3ISO 6507- 1:2005 Ed 3ISO 6507-3:2005 Ed 3ISO 23718:2007 Ed 1购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN 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.Cross References:ISO 17677-1:2009 Ed 1ISO 6507-4:2005 Ed 1ISO 6507-2:2005 Ed 3ISO 6507-1:2005 Ed 3ISO 6507-3:2005 Ed 3ISO 23718:2007 Ed 1All current amendments available at time of purchase are included with the purchase of this document.
