适用范围：This recommended practice outlines test procedures for comparing two or more unsealed or sealedinsulation systems in accordance with their expected life at rated temperature. The procedure is limited toinsulation systems for AC electrical machines using form-wound pre-insulated stator coils rated 15 000 Vand below.The intent of this test procedure is to evaluate unsealed insulation systems for use with air cooling underusual (normal) service conditions, or sealed insulation systems for use under severe environmentalconditions (where the insulation is exposed to conducting contaminants). This procedure does not coverspecial requirements, such as those for machines enclosed in gas atmospheres or machines subjected tostrong chemicals, metal dust or submersion in liquid, etc.The procedure includes instructions for testing candidate systems in comparison with known referencesystems, of the same type, having a proven record of service experience and interpreting the results of thesetests.
