IEC 62052-11-2020 Electricity metering equipment (a.c.) – General requirements, tests and test conditions – Part 11: Metering equipment. This part of IEC 62052 covers type tests for electricity metering equipment for indoor and outdoor application and applies to newly manufactured equipment designed to measure the electrical energy on 50 Hz or 60 Hz networks, with a voltage up to 600 V. It applies to electromechanical or static meters for indoor and outdoor application consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s). If the meter has a measuring element for more than one type of energy (multi-energy meters), or when other functional elements, such as maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces, etc. are enclosed in the meter case, then the relevant standards for these elements apply. t does not apply to: a) portable meters; b) data interfaces to the register of the meter; c) reference meters. For rack-mounted meters, the mechanical properties are not covered in this standard. The safety aspect is covered by IEC 62052-31 :201 5. 2 Normative references The following referenced documents are indispensable for the application of this document.
