Scope: This standard specifies the basic requirements for the design, development and process control of Class C, Class D and Class E static electric energy meters (hereinafter referred to as electric energy meters) as well as technical requirements such as measurement performance, influence of quantity and interference, test methods and inspection rules. , logo, packaging, storage, transportation and quality commitment. Note 1: Level C corresponds to level 0.5S, level D corresponds to level 0.2S, and level E corresponds to level 0.1S. This standard applies to newly manufactured metering equipment used to measure and control active electric energy in a 50 Hz or 60 Hz power grid with a voltage not exceeding 600V. All its special functional units, except for the electric energy measurement function, can be integrated in the meter. Inside the shell, a separate shell can also be formed. Note 2: The above voltages are line-to-neutral voltages derived from nominal voltages, see IEC 62052-31:2015, Table 7. This standard does not apply to: 　——laboratory and mobile electric energy meter test equipment; 　——data interface of electric energy meter registers; 　——standard meters; 　——portable electric energy meters.
