Electricity metering equipment. Dependability - Durability. Testing of the stability of metrological characteristics by applying elevated temperature1 Scope The stability of metrological characteristics is one important aspect of durability. This part of IEC 62059 specifies a method for testing the stability of metrological characteristics of electricity meters, by operating a test specimen at the upper limit of the specified operating range of temperature, voltage and current for an extended period. Functional performance other than the accuracy of energy measurement is out of the scope of this
