Full title and description

IEC 62052-11:2020 — Electricity metering equipment — General requirements, tests and test conditions — Part 11: Metering equipment. This international standard specifies type-test requirements, test methods and test conditions for AC and DC electricity meters (functional, mechanical, electrical and marking requirements), including environmental and electromagnetic immunity tests and requirements for displays, interfaces and add-on modules where applicable.

Abstract

IEC 62052-11:2020 defines the general requirements and type‑test procedures used to verify the performance, construction and environmental robustness of electricity metering equipment intended for use on mains and related installations. It covers meters with integrated or detached displays, portable meters, metering systems composed of multiple devices, and a range of auxiliary functions; it excludes meter safety (handled in a separate standard) and deliberate tampering-detection requirements.

Scope

This part of IEC 62052 specifies requirements and associated tests, with the appropriate conditions, for type testing of electricity metering equipment designed to measure and control electrical energy on electrical networks with voltages up to 1 000 V AC or 1 500 V DC. It applies to meters with all functional elements enclosed in a single meter case (with exceptions for detached indicating displays), to meters with integrated or detached displays, to multi‑device metering systems, to portable meters and to meters used in rolling stock, vehicles, ships and aircraft. The standard covers reference conditions, repeatability and measurement uncertainty for accuracy testing but does not cover meter safety requirements or fraud/tampering detection measures.

Key topics and requirements

• Nominal electrical values and ranges (voltages, currents, frequencies) and power consumption limits.
• Construction and mechanical tests: shock, vibration, window and terminal requirements, sealing provisions and protection of detached displays.
• Environmental/climatic tests: dry heat, cold, solar radiation and related acceptance criteria.
• Electromagnetic compatibility and immunity tests (EFT, ESD, radiated and conducted immunity, voltage dips and short interruptions).
• Requirements for displays, indicators, pulse outputs and data interfaces; marking and symbol requirements.
• Tests and requirements for measurement uncertainty, repeatability and time‑keeping accuracy; guidance for type test reports.
• Specification of what is outside scope (e.g., deliberate tampering detection, meter safety moved to a separate standard).

Typical use and users

IEC 62052-11:2020 is used by electricity meter manufacturers for product design and type testing, by test laboratories and certification bodies for conformity assessment, by utilities and metering system integrators to define procurement and acceptance criteria, and by regulators specifying technical requirements for metering installations and smart‑meter deployments.

Related standards

Closely related standards include the IEC 62053 series (metering performance and accuracy tests), IEC 61869 series (instrument transformers, including LPITs), and the separate IEC publication handling meter safety and related protective requirements. The 2020 edition of IEC 62052-11 cancels and replaces IEC 62052-11:2003 and its amendment.
