DIN EN ISO 21952:2008 Welding consumables - Wires electrodes, wires, rods and deposits for gas-shielded arc welding of creep-resisting steels - Classification (ISO 21952:2007); English version of DIN EN ISO 21952:2008-02
This International Standard specifies requirements for classification of wire electrodes, wires and rods for
gas-shielded metal arc welding and tungsten inert-gas welding of creep-resisting steels, and for their deposits
in the as-welded or post-weld heat-treated condition. One wire electrode can be tested and classified with
different shielding gases.
This International Standard is a combined specification providing for classification utilizing a system based
upon the chemical composition of wire electrodes, wires and rods with requirements for yield strength and
average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength of the
all-weld metal deposits and the chemical composition of wire electrodes, wires and rods.
1) Clauses, subclauses and tables which carry the suffix letter "A" are applicable only to wire electrodes,
wires, rods and deposits classified in accordance with the system based upon the chemical
composition with requirements for yield strength and the average impact energy of 47 J of all-weld
metal deposits under this International Standard.
2) Clauses subclauses and tables which carry the suffix letter "B" are applicable only to wire electrodes,
wires, rods and deposits classified in accordance with the system based upon the tensile strength of
all-weld metal deposits and the chemical composition of wire electrodes, wires and rods under this
International Standard.
3) Clauses, subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B"
are applicable to all wire electrodes, wires, rods and deposits classified under this International
Standard.
