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
machines;
– 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);
–1
• 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.
