Overview

EN 62053-11:2003/A1:2017 (equivalent to IEC 62053-11:2003/A1:2016) specifies particular requirements for electromechanical watt‑hour meters used to measure active electrical energy in alternating‑current networks (50 Hz or 60 Hz). The standard applies only to newly manufactured electromechanical meters of accuracy classes 0,5, 1 and 2 and is limited to type tests. It covers meters for indoor and outdoor use where the measuring element and register(s) are enclosed together in a single meter case, and it also addresses operation indicators and test outputs.

Key topics and requirements

• Scope and applicability: Type testing of electromechanical meters for active energy in 50/60 Hz systems; only newly manufactured meters and meters with combined measuring element and register(s).
• Accuracy classes: Requirements are defined for classes 0,5, 1 and 2, focusing on metrological performance and classification.
• Metrology and type tests: Procedures and criteria for verifying meter accuracy and behaviour under defined conditions (e.g., influence of short‑time overcurrents, self‑heating, AC voltage tests).
• Test references and cables: Some tests reference specific requirements for test cables and procedures as detailed in the related general standards.
• Separation of safety requirements: Amendment A1 removes safety tests from this document; product safety and related tests are covered by IEC 62052-31:2015 (now referenced in EN 62053-11:2003/A1:2017).
• Acceptance testing: Guidance points to acceptance inspection standards for field and batch testing (see IEC/EN 62058 series).

Practical applications

• Manufacturers use EN 62053-11:2003/A1:2017 to design and type‑test electromechanical watt‑hour meters to meet recognized European/IEC metrological performance levels.
• Test laboratories and conformity assessment bodies apply the standard when performing type approval and verification of meter accuracy and behaviour under specified test conditions.
• Utilities, metering procurement teams, and regulators reference the standard when specifying meter performance, acceptance criteria, and compliance for legacy electromechanical installations.
• Engineers responsible for retrofit, maintenance, or comparative testing of meters use the standard as a benchmark for metrological characteristics.

Related standards

• IEC 62053-11 / EN 62053-11 (base document)
• IEC 62052-31 / EN 62052-31 - product safety requirements and tests (now covers safety aspects removed by A1)
• IEC 62052-11 / EN 62052-11 - general metering equipment requirements
• IEC/EN 62058‑11 and 62058‑21 - acceptance inspection methods and particular requirements for electromechanical meters

This standard is essential for anyone involved in the type testing, manufacture, procurement, or regulatory compliance of electromechanical active‑energy meters in 50/60 Hz electricity networks.
