This standard is a revision of ZBJ6202689 "Technical requirements for double-disc storage friction press". The main difference between this standard and ZBJ62026-89 is the modification of the effective energy test material diagram, the elimination of the provisions that conflict with the relevant safety standards, and the detailed provisions of the type inspection and factory inspection items. This standard has been implemented since its implementation. This standard replaces ZBJ62026-89. Appendix A and Appendix B of this standard are both appendices of the standard. Appendix C of this standard is the appendix of the standard.
The standard is proposed and managed by the National Technical Committee for Standardization of Presses. The drafting unit of this standard is Qingdao BanZhu Machinery Group Co., Ltd. The main drafters of this standard are Xing Jibai, Rong Mingzheng, and Li Gaijun. This standard was first issued in April 1982.
