GB/T 12351-2008Environmental technical requirements of rotating electric machines for tropical use (English PDF)

Foreword

This standard replaces GB/T 12351-1990 "tropical rotary motor ambient technical requirements."

This standard compared with the original GB/T 12351-1990, there are major differences between.

--- Reference standard was updated;

--- Increased "leakage current 4.2.5" clause;

--- 4.3.3 adds provisions relating to motor parts natural outdoor exposure test;

--- Deleted Appendix A, the contents of a direct reference to GB/T 9286 "Paints and varnishes cut test" relevant "content.

The standard proposed by China Electrical Equipment Industrial Association.

This standard by the National Standardization Technical Committee of the motor rotation.

This standard was drafted. China Electric Apparatus Research Institute.

The main drafters of this standard. Yan Jinglian, Liao Guoqing.

This standard replaces the standards previously issued as follows.

Tropical rotary motor ambient technical requirements
