This standard is a revision of JB/T7988.3-1995 "Marking and Packaging of Artificial Diamond or Cubic Boron Nitride". This standard modifies and supplements the measurement units and packaging requirements of packaging quantity in JB/T7988.3-1995 to make it more perfect. This standard is renamed "Marking and Packaging of Superhard Abrasives". This standard replaces JB/T7988.3—1995 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 as JB2808-79 and JB3049-82, and was revised for the first time as GB6406.5-86 in May 1986. The standard number was adjusted to JB/T7988.3--1995 in April 1996. This is the second revision. 1 Scope
