Scope

GB/T 17215.221-2021 is the English-translated version of 电测量设备（交流）通用要求、试验和试验条件第21部分：费率和负荷控制设备.

GB/T 17215.221-2021 is the Chinese standard "Electricity metering equipment(a. c. ) - General requirements, tests and test conditions - Part 21: Tariff and load control equipment".

Its scope clause reads: This part of GB/T 17215.2 specifies the newly-manufactured, indoor-use tariff and load control equipment (for example. used to control electrical loads).

General requirements for type testing of electronic ripple control receivers and time switches for load, multi-rate counters and maximum demand indicators. This section does not make requirements for the internal structure details of the tariff and load control equipment.

If the tariff and load control functions are integrated into the multi-function instrument, the relevant parts of this section also apply. This section does not cover acceptance inspection and conformity inspection.

Refer to Appendix F for acceptance inspection requirements. The general requirements for safety are detailed in IEC 62052-31.2015. The general requirements for reliability are detailed in the IEC 62059 series of standards in the reference.
