This International Standard 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
high-strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength
greater than 570 MPa.
This International Standard is a combined specification providing a classification utilizing a system based upon
the yield strength and an average impact energy of 47 J of the all-weld metal, or utilizing a system based upon
the tensile strength and an average impact energy of 27 J of the all-weld metal.
a) Subclauses and tables which carry the suffix letter “A” are applicable only to covered electrodes classified
under the system based upon the yield strength and an average impact energy of 47 J of the all-weld
metal given in this International Standard.
b) Subclauses and tables which carry the suffix letter “B” are applicable only to covered electrodes classified
under the system based upon the tensile strength and an average impact energy of 27 J of the all-weld
metal given in this International Standard.
c) Subclauses and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to
all covered electrodes classified under this International Standard.
