Full Description

ISO 2560:2009 specifies requirements for 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 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.

ISO 2560:2009 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.

Paragraphs 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 allweld metal in ISO 2560:2009.

Paragraphs 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 allweld metal in ISO 2560:2009.

Paragraphs and tables which do not have either the suffix letter A or the suffix letter B are applicable to all covered electrodes classified in ISO 2560:2009.
