JB/T9943—1999
This standard is based on the basic code of ZBJ42034-89 Silicon Grid Linear Displacement Sensor Technical Conditions. This standard is basically consistent with ZBJ42034-89, with the main differences being: appropriate adjustments have been made to the single and complex indicators; and the relevant regulations have been revised.
This standard replaces ZBJ42 034-89 from the date of implementation. This standard was proposed and drafted by the National Technical Committee for Standardization of Metal Cutting Machine Tools. The responsible drafting unit of this standard is Shanghai Machine Tool Research Institute. The main drafters of this standard are Zhang Lianting and Wang Guqiao. This standard was first issued in June 1989.
