Applicable to machines covered by IEC 60034-1 when they cannot be loaded to a specific condition (rated or otherwise). It is applicable to both motors and generators.

IEC 60034-29 provides various indirect load tests, the purpose of which is to determine the temperature rise of rotating electrical machines, including a.c. induction machines, a.c. synchronous machines and d.c. machines. The test methods in some cases provide, in addition, means of measuring or estimating other parameters such as losses and vibration. Applies to machines covered by IEC 60034-1 when they cannot be loaded to a specific condition. Is applicable to both motors and generators.
