UNE-EN ISO 2560:2021

This document specifies requirements for the classification of covered electrodes and deposited metal in

the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of nonalloy

and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength

of up to 570 MPa.

This document is a combined specification providing for 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.

a) Clauses, subclauses and tables which carry the suffix letter A are applicable only to covered

electrodes classified to the system based upon the yield strength and the average impact energy of 47 J

of all weld metal in this Document.

b) Clauses, subclauses and tables which carry the suffix letter B are applicable only to covered

electrodes classified to the system based upon the tensile strength and the average impact energy of 27 J

of all weld metal in this Document.

c) Clauses, subclauses and tables which do not have either the suffix letter A or the suffix letter B

are applicable to all covered electrodes classified in this Document.
