JB/T 8002-1999 This standard is a revision of JB/T 8002-95 "Artificial diamond or cubic boron nitride abrasive paste". The original national standard was formulated with reference to the former Soviet Union standard ГОСТ 25593-83 "Technical conditions for diamond abrasive paste" and other foreign standards. During the revision, only editorial changes were made according to relevant regulations, and the main technical content remained unchanged. This standard specifies the product code, use, marking, technical requirements, inspection rules and marking, packaging, transportation, storage, etc. of artificial diamond or cubic boron nitride abrasive paste. This standard is applicable to artificial diamond or cubic boron nitride abrasive paste for grinding and polishing metal and non-metallic materials. This standard was first issued on March 31, 1989 as GB 11273-89 and adjusted to JB/T 8002-95 in April 1996.
