QB/T 3665—1999
This standard is originally the professional standard ZB/TY91010--1989 Technical Conditions for Natural Granite Frame, and was renamed as QB/3665—1999 through the promulgation of Document No. 112 of the State Light Industry Bureau (21999). The content remains unchanged. This standard is issued by the Industry Management Department of the State Light Industry Bureau. This standard is issued by the Shandong Paper Machine City Production and Production Company, a member of the National Light Industry Machinery Standardization Association. The main drafters of this standard are Liu Jinbu and Shou Baowei. From the date of implementation, this standard will replace the original light industry standard ZB/Y91010-1989 Technical Conditions for Natural Granite Light Extraction issued by the People's Republic of China. Technical Conditions for Natural Granite Pressing Rods Production Content and Application Scope QB/T3665-1999 This standard specifies the technical requirements, test methods, processing rules, marking, packaging, transportation, storage and other related requirements for natural granite H control rods (hereinafter referred to as granite).
