1 Scope This national standard specifies energy efficiency grades, minimum allowable values of energy efficiency, evaluating values of energy conservation and test method for fans. This standard is applicable to centrifugal and axial-flow fan for common use, centrifugal induced fan for industrial steam boiler, centrifugal blowing fan and induced fan for power boiler, axial-flow fan for power station and air conditioning centrifugal fan. This standard id not applicable to the fan with special structure and special purpose, like ejector type ventilator and transverse flow type fan. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this national standard. For dated reference, subsequent amendments (excluding amending error in the text) to, or revisions of, any of these publications do not apply. However, the parties whose enter into agreement according to these specifications are encouraged to research whether the latest editions of these references are applied or not. For undated references, the latest edition of the normative document is applicable to this national standard.
