ISO 14271:2011 Resistance welding - Vickers hardness testing (low-force and microhardness) of resistance spot, projection, and seam welds

standard by International Organization for Standardization, 09/01/2011

Full Description

ISO 14271:2011 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.
