    Abstract - (Show below) - (Hide below)

    Specifies maximum A-weighted sound power levels, L[WA] in decibels, dB, for airborne noise emitted by rotating electrical machines of standard design, as a function of power, speed and load, and to specify the method of measurement and the test conditions appropriate for the determination of the sound power level of the machines to provide a standardized evaluation of machine noise up to the maximum specified sound power levels.
