This standard specifies the energy efficiency grades,minimum allowable values of energy efficiency and testing methods of three-phase asynchronous motors,single-phase asynchronous motors and air conditioner fan motors.
This standard is applicable to general motors and general explosion-proof motors of which the power is supplied by 50 Hz three-phase AC power supply,with the rated voltage of less than 1 000 V,the rated power ranging from 120 W to 1 000 kW,2,4,6 or 8 poles,single-speed enclosed fan-cooled type,N design and continuous duty. This standard is also applicable to the general motors (e.g. capacitor-start asynchronous motors (120 W~3 700 W),capacitor-run asynchronous motors (120 W~2 200 W) and two-value capacitor asynchronous motors (250 W~3 700 W)) supplied by 50 Hz AC power supply with the voltage of≤690 V,and the capacitor-run asynchronous motors (10 W~1 100 W) and brushless DC motors (10 W~1 100 W) for air conditioner fans.

This standard specifies the maximum allowable values of power consumption per kilogram and water consumption per kilogram,evaluating values for power conservation and water conservation,as well as power and water efficiency grades for household electric washing machines.
This standard is applicable to household electric washing machines with rated washing capacities equal to or less than 13 kg (hereafter referred to as "washing machines").
This standard is not applicable to washing machines with rated washing capacities equal to or less than 1.0 kg or single-compartment washing machines without water-extracting functions. This document is not applicable to agitator washing machines either. As for washer-dryers,only the washing function shall be assessed in this document.
