UNE-EN ISO 3581:2016

This International Standard specifies requirements for classification of covered electrodes, based on the all-weld metal chemical composition, the type of electrode covering and other electrode properties, and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of stainless and heat-resisting steels.

This International Standard is a combined standard providing for classification utilizing a system based upon classification according to nominal composition, or utilizing a system based upon classification according to alloy type.

a)Paragraphs and tables which carry the label classification according to nominal composition or ISO 3581-A are applicable only to products classified to that system.

b)Paragraphs and tables which carry the label classification according to alloy type or ISO 3581-B are applicable only to products classified to that system.

c)Paragraphs and tables which carry neither label are applicable to products classified according to either or both systems.
