Scope

Scope: This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage for sintered NdFeB permanent magnets with the brand names N50SH and N52SH. This standard applies to sintered NdFeB permanent magnets produced by powder metallurgy processes, and is used in fields such as electronics, power, machinery, and medical devices for the manufacture of permanent magnet devices and other applications. Main technical content: 【Preface】 This standard is a supplement to the national standard GB/T 13560-2017 "Sintered NdFeB Permanent Magnets". Two new product specifications, S-NdFeB-390/151 (N50SH) and S-NdFeB-415/151 (N52SH), are added to the requirements, making it necessary to formulate this standard. 1. Scope This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage for sintered NdFeB permanent magnets with the brand names N50SH and N52SH. This standard applies to sintered NdFeB permanent magnets produced by powder metallurgy processes, and is used in fields such as electronics, power, machinery, and medical devices for the manufacture of permanent magnet devices and other applications. 2.
