This Standard specifies energy efficiency grade, minimum allowable values of energy efficiency, target minimum allowable values of energy efficiency, evaluating values of energy conservation, and test method for small-power asynchronous motors. This Standard is applicable to general purpose motors - small-power 3-phase asynchronous motor (10 W to 2200 W) powered by 50 Hz 690 VAC and below voltage; capacitor running asynchronous motor (10 W to 2200 W); capacitor starting asynchronous motor (120 W to 3700 W), double-value capacitor asynchronous motor (250 W to 3000 W); and motor (6 W to 550 W) for air conditioning fan in room etc.
