1 Scope
Replace the first paragraph of the scope with the following:
This part of IEC 60034:

– specifies test methods for the determination of sound power level of rotating electrical


– specifies maximum A-weighted sound power levels for factory acceptance testing of

network-supplied, rotating electrical machines in accordance with lEC 60034-1, having

methods of cooling according to lEC 60034-6 and degrees of protection according to

lEC 60034-5, and having the following characteristics:

• standard design, either a.c. or d.c., without additional special electrical, mechanical, or

acoustical modifications intended to reduce the sound power level;
• rated output from 1 kW (or kVA) up to and including 5 500 kW (or kVA);
• rated speed not greater than 3 750 min .

– provides guidance for the determination of noise levels for a.c. cage induction motors

supplied by converters.
