Full title and description

IEC 62053-11:2003+A1:2016 (edition 1.1) — Electricity metering equipment (a.c.) — Particular requirements — Part 11: Electromechanical meters for active energy (accuracy classes 0.5, 1 and 2). This consolidated edition combines the original 2003 publication with Amendment 1 (2016) and includes the corrigendum of March 2018; it specifies type-test requirements for electromechanical watt-hour meters used for measurement of alternating-current active energy in 50 Hz or 60 Hz networks.

Abstract

This part of IEC 62053 applies to newly manufactured electromechanical watt‑hour meters (measuring element and register enclosed in a single meter case) intended for indoor and outdoor use and intended to measure active energy in AC networks (50/60 Hz). It defines metrological and type-test requirements, required indicators and test outputs, and test conditions for accuracy classes commonly used for billing and meter verification.

General information

• Status: Consolidated international standard (edition 1.1) — active/stable (stability date recorded to 2029 by IEC).
• Publication date: 18 November 2016 (consolidated edition IEC 62053-11:2003+A1:2016, ed.1.1).
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 17.220.20 — Measurement of electrical and magnetic quantities / Electricity metering equipment.
• Edition / version: Edition 1.1 (consolidated: IEC 62053-11:2003 + Amendment 1:2016, corrigendum incorporated).
• Number of pages: 74 pages (consolidated document).

Scope

The standard applies only to electromechanical watt‑hour meters of accuracy classes 0.5, 1 and 2 for measurement of alternating‑current active energy in 50 Hz or 60 Hz networks. It is intended for type testing of meters that consist of a measuring element and register(s) enclosed together in a meter case, and it covers indoor and outdoor applications, operation indicators and test outputs. The document addresses metrological performance, environmental and mechanical influences relevant for billing‑grade electromechanical meters.

Key topics and requirements

• Definition of applicable meter types (electromechanical watt‑hour meters) and permissible accuracy classes (0.5, 1, 2).
• Type‑test procedures for metrological performance (accuracy under reference and influence conditions).
• Environmental, climatic and mechanical tests (temperature, humidity, vibration, shock) and influence quantities that may affect accuracy.
• Tests and requirements for operation indicators and test outputs (verification and testing interfaces).
• Requirements for starting current, influence of frequency and voltage variations, and instructions for type‑test reporting.
• Consolidation notes: this consolidated edition incorporates Amendment 1 (2016) and the March 2018 corrigendum.

Typical use and users

Primary users are electricity meter manufacturers (design and type‑testing), national metrology institutes and testing laboratories (type approval and verification), utilities and distribution companies (procurement and acceptance testing), regulators and conformity assessment bodies. The standard is used to ensure meters meet required billing accuracy and environmental robustness prior to deployment.

Related standards

IEC 62053‑11 is part of the IEC 62053 family (particular requirements for electricity metering equipment) and is intended to be used together with the IEC 62052 series (general requirements, tests and test conditions — e.g., IEC 62052‑11 and IEC 62052‑31 for product safety), other parts of IEC 62053 (static meter parts such as IEC 62053‑21/‑22/‑23/‑24), and complementary documents (IEC 62058 acceptance inspection, IEC 62057 test equipment guidance). These related parts define general test methods, safety, acceptance inspection and accuracy class requirements for other meter technologies.

FAQ

Q: What is this standard?

A: IEC 62053‑11:2003+A1:2016 (ed.1.1) is the IEC particular‑requirements standard that specifies type‑test and metrological requirements for electromechanical watt‑hour meters measuring active energy (accuracy classes 0.5, 1 and 2).

Q: What does it cover?

A: It covers electromechanical meter construction (measuring element plus register enclosed in one case), type tests for accuracy and influence quantities (temperature, humidity, vibration, voltage/frequency variation), operation indicators and test outputs, and reporting requirements for type‑testing.

Q: Who typically uses it?

A: Meter manufacturers, test laboratories and national metrology institutes for type approval; utilities and regulators for procurement and conformity assessment; and certification bodies for compliance verification.

Q: Is it current or superseded?

A: The consolidated edition (IEC 62053‑11:2003+A1:2016, ed.1.1) was published 18 November 2016 and includes the March 2018 corrigendum; IEC lists this consolidated version as edition 1.1 and records stability to 2029, so it remains the valid consolidated document for the electromechanical requirements until official revision or withdrawal.

Q: Is it part of a series?

A: Yes — it is Part 11 of the IEC 62053 series (particular requirements for electricity metering equipment). The IEC 6205x family and related IEC 62052 documents together cover general requirements, static meter requirements, reactive energy meters, acceptance inspection and test equipment guidance.

Q: What are the key keywords?

A: Electromechanical meter, watt‑hour, active energy, accuracy class 0.5/1/2, type test, metrological performance, IEC 62053, TC 13.
