YB/T 4379-2014 (English Version) PDF

Scope: This standard specifies the grade representation and classification, technical requirements, test methods, inspection rules, packaging, marking, storage, transportation and quality certificates of isostatic graphite. This standard applies to graphite products made from high-quality petroleum coke, pitch coke, etc. as the main raw materials, through pulverization (average particle size less than 25 μm), kneading, isostatic pressing, roasting, impregnation, graphitization and other processes.
