JB/T3234—1999
This standard is a revision of JB323483 "Synthetic diamond sintered body for wire drawing dies". The original standard acceptance inspection adopts percentage sampling quantity. This standard is revised to be inspected and accepted in accordance with GB/T2828-1987 "Batch Inspection Count Sampling Procedure and Sampling Table (Applicable to Inspection of Continuous Batch)". Other technical contents are basically consistent with JB323483, and only re-edited according to relevant regulations.
This standard replaces JB323483 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Standardization of Abrasives and Grinding Tools. The drafting unit of this standard: Zhengzhou Abrasives and Grinding Research Institute. The main drafter of this standard: Huang Xiangfen.
This standard was first issued on June 4, 1983. 1 Scope
