DIN EN ISO 21952:2012-08

This standard has been prepared by applying the cohabitation principle, that means, two approaches, subdivided into A and B, are specified for the same subject to be standardized. Approach A mainly reflects the European specifications; approach B mainly reflects the specifications in the Pacific Rim. It shall be noted that it shall be laid down according to which approach (A or B) products shall be manufactured or supplied before this standard is applied. This standard specifies requirements for classification of wire electrodes, wires and rods for gas shielded metal arc welding and tungsten inert-gas welding of creep-resisting steels, and for their deposits in the as-welded or post-weld heat-treated condition. In comparison to the existing standard ISO 21952:2007 it is intended to add more alloys on the B-side and to make adjustments with regard to shielding gas designations in accordance with ISO 14175. The International Standard ISO 21952:2010 has been prepared by ISO/TC 44/SC 3 "Welding consumables" within the framework of the Vienna Agreement together with CEN/TC 121 "Welding". The responsible committee is NA 092-00-03 AA "Schweißzusätze (DVS AG W 5)" ("Welding consumables (DVS AG W 5)") at DIN.
