Scope

This standard specifies the shape, dimensions and tolerances, technical
requirements, test methods, inspection rules, packaging, marking, storage,
transportation and quality certificates of ultra high-power graphite electrodes.
This standard is applicable to ultra high-power graphite electrodes made of
needle coke and coal tar pitch as main raw materials, formed by molding,
burning, impregnation, graphitization and mechanical processing, and used as
the conductive materials for electric furnace.
