Annotation of standard text ČSN EN IEC 60034-2-2-ed.2 (350000):

This part of IEC 60034 applies to large rotating electrical machines and establishes additional methods of determining separate losses and to define an efficiency supplementing IEC 60034-2-1. These methods apply when full-load testing is not practical and results in a greater uncertainty.
The specific methods described are Calibrated-machine method, Retardation method, Calorimetric method and Summation of losses for permanent magnet excited synchronous machines
