1 Scope This standard specifies the energy efficiency grades minimum allowable values of energy efficiency, evaluating values of energy conservation, test methods, inspection rules and energy efficiency grade identification of waste submersible motor-pumps. This standard is applicable to single-phase or three-phase waste submersible motor-pumps (hereinafter referred to as "motor-umps") that transport all kinds of sewage or mixed liquids containing insoluble solids such as silt, fiber, feces and river mud fertilizer. 2 Normative references The following referenced documents are indispensable for the application of this standard.
