JB/T9531-1999
This standard is equivalent to ISO5827:1983 "Spot welding electrode back-ups and clamps". This standard is a revision of ZBJ6401388 "Spot welding electrode back-ups and clamps". According to the requirements of GB/T1.1-1993 and GB/T1.3-1997, only ZBJ64013-88 has been edited. From the date of implementation, this standard will replace ZBJ64013-88. This standard is proposed and managed by the National Electric Welding Machine Standardization Technical Committee. The drafting unit of this standard: Shenyang Electric Welding Machine Factory. The main drafters of this standard: Bai Tao, Zhang Lijuan. Xiaoniu Standard Nanny
