• have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays;
• operate with integrated or detached indicating displays, or without an indicating display;
• be installed in a specified matching socket or rack;
• optionally, provide additional functions other than those for measurement of electrical energy.
This document does not apply to:
• meters for which the voltage line-to-neutral derived from nominal voltages exceeds 1 000 V AC;
• meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series) when tested without such transformers;
• metering systems comprising multiple devices physically remote from one another.
• portable meters;
• meters used in rolling stock, vehicles, ships and airplanes;
• laboratory and meter test equipment;
• reference standard meters;

• any additional functions provided in electrical energy meters.
This document does not cover measures for the detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering)
This second edition cancels and replaces the first edition published in 2003 and its amendment 1: 2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Removed all meter safety requirements; the meter safety requirements are covered in IEC 62052-31: 2015.
b) Moved the descriptions of all general requirements and test methods from IEC 62053-21: 2003, IEC 62053-22: 2003, IEC 62053-23: 2003, IEC 62053-24: 2003 to IEC 62052-11:2020; IEC 62053-21:2020, IEC 62053-22:2020, IEC 62053-23:2020, IEC 62053-24:2020 contain only accuracy class specific requirements.
c) Added new requirements and tests concerning:
1) active energy meters of accuracy class 0,1S;
2) measurement uncertainty and repeatability (7.3, 7.8);
3) influence of fast load current variations (9.4.12);
4) immunity to conducted differential current disturbances in the 2 kHz to 150 kHz frequency range (9.3.8)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62053-22 has been prepared by IEC technical committee 13:
Electrical energy measurement and control.
This second edition cancels and replaces the first edition published in 2003 and its
amendment 1: 2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition: see Annex B.
The text of this International Standard is based on the following documents:
FDIS Report on voting
13/1806A/FDIS 13/1814/RVD

Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 62053 series, published under the general title Electricity metering
equipment – Particular requirements, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation nationally
not earlier than 2 years from the date of publication.
