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 62041 has been prepared by Technical Committee 96:
Transformers, reactors, power supply units and combinations thereof.
This third edition cancels and replaces the second edition published in 2010. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• the inclusion of a clause on tests in series production;
• the inclusion of a new clause on measurement uncertainly, and
• the status of a harmonized standard for this third edition.
It has the status of a product family EMC standard in accordance with IEC Guide 107:2009,

The text of this International Standard is based on the following documents:
FDIS Report on voting
96/465/FDIS 96/467/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.
This standard is to be used in conjunction with the IEC 61558 series.
In this standard, the following print types are used:
• requirements proper: in roman type;
• test specifications: in italic type;
• explanatory matter: in smaller roman type.
In the text of this publication, the words in bold are defined in Clause 3 of this document and
in the IEC 61558 series.
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.
A bilingual version of this publication may be issued at a later date.
NOTE The attention of the 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 12 months or not later than 3 years from the date of publication.
The transitional period is no longer than 3 years after the publication of this standard.

EMC requirements



1 Scope
This document is applicable to transformers, reactors and power supply units covered by the
IEC 61558 series of standards. This document deals with the electromagnetic compatibility
requirements for emission and immunity within the frequency range 0 Hz to 400 GHz. No tests
need to be performed at frequencies where no requirements are specified.
For associated transformers, associated reactors and associated power supply units either
supplied with or incorporated into an appliance or equipment the relevant EMC standard for
that appliance or equipment applies.
This document covers normal operating conditions only. Other operations of the transformers,
reactors and power supply units (e.g. simulated faults in the electric circuitry for testing
purposes or functional safety due to the effects of the electromagnetic phenomena, or
evaluation of human being for exposure to electromagnetic fields (EMF)) have not been taken
into consideration in this document.
Requirements are specified for each port considered. If requirements are different the most
severe takes precedence.
This document may also be used as a guide to test transformers, reactors and power supply
units separately before these are incorporated into an appliance or equipment.
NOTE When EUT (Equipment under test) is used, it covers transformers, reactors and power supply units
where applicable.
This document does not apply to:
• uninterruptible power supplies (UPS) covered by IEC 62040 (all parts);
• power supply units covered by IEC 61204,
(i.e. DC-DC converters, DC power and distribution equipment and power supply units for
use in applications covered by IEC 60950-1, IEC 61010-1, IEC 60601-1 and IEC 60065);
• power supplies and converters for use with or in products covered by IEC 61347 (all
parts).
