Revision Standard – Superseded. Superseded by 112-1996 and 112-2004. Instructions are given for conducting and reporting the more generally applicable and acceptable tests to determine the performance characteristics of polyphase induction motors and generators. Electrical measurements, performance testing, temperature tests, and miscellaneous tests are covered.<\/p>\n
