Scope: This standard specifies the classification and technical requirements, test methods, inspection rules, packaging, marking, storage, transportation and quality certificates of fine-grained high-density special graphite products. This standard applies to fine-grained high-density graphite products with a maximum particle size of not more than 0.8 mm, which are made from calcined petroleum coke as the main raw material through molding, roasting, impregnation, graphitization and mechanical processing. This graphite product can be widely used in metallurgy, chemical industry, casting, graphite deep processing and other fields.
