Resistance welding - Vickers hardness testing (low-force and microhardness) of resistance spot, projection and seam welds (ISO 14271:2011); German version EN ISO 14271:2011
Widerstandsschweißen - Vickers-Härteprüfung (Kleinkraft- und Mikrohärtebereich) von Widerstandspunkt-, Buckel- und Rollennahtschweißverbindungen (ISO 14271:2011); Deutsche Fassung EN ISO 14271:2011
Overview
This standard describes the procedure for the hardness testing of etched cross-sections of resistance spot, projection, and seam welds. The aim of the hardness test 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. The International Standard ISO 14271:2011 upon which European Standard EN ISO 14271:2011 is based has been prepared by the International Institute of Welding (IIW). Joint Working Committee NA 092-00-12-07 AK "Prüfen von Widerstandsschweißverbindungen (DVS AG V 3.9)" ("Testing of resistance-welded joints (DVS AG V 3.9)") at DIN is responsible for this standard.
