Standards
ABB strongly supports the drive to harmonise European standards and actively
contributes to various working groups within both IEC and CENELEC.
IEC defines:

IEC 60034-2: Methods for determining losses and efficiency of rotating
electrical machinery from tests
IEC 60034-8: Terminal markings and direction of rotation of rotating
machines
IEC 60034-12: Starting performance of single-speed three-phase cage
induction motors for voltages up to and including 660V
