FT-106B Superhard material bulk density tester

一． 標準standard：

JB/T 3584-1999 本標準是對 JB 3584-84《超硬磨料堆操作密度測定方法》的修訂。本標準非等效采用美國標準 ANSI B74.17-1976《金剛石磨粒堆積密度的檢驗方法》

JB/T 3584-1999 is a revision of the JB 3584-84 "super hard abrasive heap operation density test method".This standard is not equivalent to the American national standard ANSI B74.17-1976 “The test method for the bulk density of the diamond grinding grain”

本標準適用于粒度為 16/20~325/400 的人造金剛石和立方氮化硼的堆積密度測定

This standard applies to the measurement of the bulk density of the synthetic diamond and cubic boron nitride which in 16/20 ~ 325/400
