Scope
Scope: This document proposes insulation specifications for low-voltage three-phase asynchronous motors used in closed-type refrigeration compressors (hereinafter referred to as motors), and stipulates the technical requirements, inspection rules, and diagnostic tests for single materials and insulation systems. This document applies to the insulation systems of motors with a rated voltage of 1,140 V or lower. This document does not apply to the insulation systems of motors that use ammonia as a refrigerant.
