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 AC or DC, 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–1 Excluded are noise limits for AC motors supplied by converters. For these conditions see Annex B for guidance.
