ISO 2560规定了最小屈服强度高达500 N/mm2或最小抗拉强度高达570 N/mm2的非合金钢和细晶粒钢的手工金属电弧焊的焊条和熔敷金属在焊接状态和焊后热处理状态下的分类要求。 它是一个组合规范，提供了利用基于全焊接金属的屈服强度和47 J的平均冲击能量的系统，或利用基于全焊接金属的拉伸强度和27 J的平均冲击能量的系统进行分类。

ISO 2560 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 non-alloy and fine grain steels with a minimum yield strength of up to 500 N/mm² or a minimum tensile strength of up to 570 N/mm². It is a combined specification providing for classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal.
