Mechanical Industry Standard of the People's Republic of China JB/T9542 1999-08-06Juan Wa Xianji Dong 2000-01-01Xiaolian JB/T9542 This standard is a revision of ZBK2000389 "Technical Conditions for Dual-value Capacitor Asynchronous Motors". On the basis of the original standard, this standard adds a preface and table of contents, changes the standard number, and the standard content remains basically unchanged. According to the provisions of GB/T1.3, Chapter 5 "Test Methods" is added, the original Chapter 5 "Inspection Rules" is included in Chapter 6, and the content of the relevant test methods is placed in Chapter 5. The original Chapter 1 "Subject Content and Scope of Application" is changed to "Scope", and the original Chapter 6 "Marking, Packaging" is changed to Chapter 7 "Marking, Packaging, Transportation and Purchase and Storage". This standard replaces ZBK20003-89 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Standardization of Rotating Electric Machines. The responsible unit for drafting this standard is Guangzhou Electric Science Research Institute. The main drafters of this standard are He Wenshuo, Su Shihua, Wu Guoping, and Huang Zhu. This standard is interpreted by the National Technical Committee for Standardization of Condensing and Rotating Electric Machines, the Technical Committee for Standardization of Small Power Electric Machines.
