Defines a classification and designation system for the electrodes and specifies two series which provide minimum weld metal strengths of 410 and 480 MPa. Provision is made for hydrogen controlled and metal-enriched electrodes. Requirements are given for size of electrodes, core wire, flux covering, testing, safety warnings, packing, marking and storage. Tests include chemical analysis of weld metal, all-weld-metal tensile and impact tests, butt weld tensile, bend and impact tests, and a fillet weld test. A hydrogen test and coating moisture absorption resistance test are also prescribed.
