Hermetic Motor - Compressors for
Refrigerators
1 Scope
This Standard specifies the terms and definitions, product classification, technical requirements, test methods, inspection rules and the requirements of marking, packaging, transportation and storage of hermetic motor-compressors for refrigerators. The safety requirements of compressor are detailed in GB 4706.17 "Household and Similar Electrical Appliances - Safety - Particular Requirements for
Motor-Compressors".
This Standard is applicable to the hermetic motor-compressors used for
low-back-pressure * household and similar electric refrigerators with R600a and R134a refrigerants, and the nominal refrigerating capacity not exceeding 400 W under the specified working conditions in this Standard (hereinafter referred to as ?€?compressor?€?).
For similar compressors with other types of refrigerants, this Standard may also be referred to.
This Standard is not applicable to vehicular refrigerator compressors.
