This document specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of core, shielding gas, welding position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels.
This document is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type.
a) Clauses, subclauses, and tables which carry the suffix "System A" are applicable only to products classified using the system based upon nominal composition.
b) Clauses, subclauses, and tables which carry the suffix "System B" are applicable only to products classified using the system based upon alloy type.
c) Clauses, subclauses, and tables which do not have either the suffix "System A" or "System B" are applicable to all products classified in accordance with this document.
This document does not use pulsed current for determining the product classification, neither does it address ferrite numbers (see Annex D and ISO/TR 22824)
