1 Scope
This standard specifies the maximum allowable value of energy consumption, the judgement methods for energy efficiency grade and energy conservation evaluation value, the energy consumption test method and the inspection rules of household refrigerators (hereinafter referred to as refrigerator).
This standard is applicable to household refrigerators with motor-driven compression (including 500 L and above), wine cooler and built-in refrigerating appliance. It is not applicable to refrigerator products exclusively used for transparent door exhibition or other special purposes.
