DIN EN ISO 14341:2011-04

This International Standard specifies requirements for classification of wire electrodes and weld deposits in the as-welded condition and in the post-weld heat-treated condition for gas shielded metal arc welding of non alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa. One wire electrode can be tested and classified with different shielding gases. This standard constitutes a combined specification providing classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal. The International Standard ISO 14341 has been prepared by applying the cohabitation principle, that means, two approaches, which are 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 the standard DIN EN ISO 14341 is applied. With respect to the previous edition, the differentiation between approach A and B for the symbols according to ISO 14175 and the tables for the chemical composition were modified, amongst others. The International Standard ISO 14341:2010 has been prepared by ISO/TC 44 "Welding and allied processes" and has been adopted identically as EN ISO 14341:2010 by Technical Committee CEN/TC 121 "Welding" (secretariat: DIN, Germany). The responsible German standardization committee is Working Committee NA 092-00-03 AA "Schweißzusätze (DVS AG W 5)" ("Welding consumables (DVS AG W 5)") of the Welding Standards Committee (NAS).
