T/ZAWS 001-2023 Safety Specifications for the Production Process of NdFeB Magnetic Materials

Scope

Scope: This standard specifies the safety technical requirements for the production of sintered NdFeB permanent magnet materials blanks using rare earth metals such as praseodymium, neodymium, cerium, boron iron, gadolinium iron, and dysprosium iron as the main raw materials. The requirements cover basic safety conditions of production equipment, process safety, and operational safety. The electroplating process for finished sintered NdFeB permanent magnet materials is not applicable to this standard. Main technical content: This standard stipulates the applicable scope, normative referenced documents, terms and definitions of the standard, and puts forward specific requirements for the general safety requirements of NdFeB magnetic material production processes, the safety of raw material processing, the safety of melting and rapid casting processes, the safety of hydrogen breaking processes, the safety of powder production processes, the safety of molding processes, the safety of sintering processes, and the safety of machining processes. In the appendix, informative materials such as the production process of NdFeB magnetic materials, the main risk identification of each link in the production process, and the individual protective equipment configuration for NdFeB magnetic material production are presented.
