Scope
This part of GB/T 17215 specifies a test method for the stability of metering characteristics of electric energy meters, which is to let the test sample run for a long period of time under the upper limit of the specified temperature, voltage and current working range, and test it in The change in percent error during and after recovery. Performance characteristics other than energy metering accuracy are outside the scope of this standard. This section applies to all types of energy meters within the scope of IEC/TC 13.
