Gives requirements for classifying wires, wire electrodes, rods and weld deposits in the as-welded and stress relieved condition for gas shielded metal arc welding and gas tungsten arc welding of steel with a minimum yield strength above 500 N/mm2. Wire electrode, wire and rod classification is based upon their chemical composition and classification of a weld deposit is based on all-weld metal tests in the as-welded or stress relieved condition.
