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 second edition cancels and replaces the first edition published in 2003. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– the frequency range for tests according to IEC 61000-4-3 has been extended above 1 GHz
according to technologies used in this frequency area;
– the testing requirements according to IEC 61000-4-11 have been amended significantly;
– the inclusion of a clause on tests in series production;
– the inclusion of a new clause on measurement uncertainly, and
– the inclusion of requirements on DC power ports and telecommunication ports.

It has the status of a product family EMC standard in accordance with IEC Guide 107:2009,
Electromagnetic compatibility – Guide to the drafting of electromagnetic compatibility

The text of this standard is based on the following documents:
FDIS Report on voting
96/358/FDIS 96/367/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This standard is to be used in conjunction with 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 standard and in
the IEC 61558 series.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication 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 12 months from the date of publication.

SAFETY OF TRANSFORMERS, REACTORS,

EMC REQUIREMENTS



1 Scope
This international product family standard applies to transformers, reactors, power supply
units and combinations thereof covered by the IEC 61558 series of standards. This standard
deals with the electromagnetic compatibility requirements for emission and immunity within the
frequency range 0 Hz - 400 GHz. No measurement needs to be performed at frequencies
where no requirement is specified.
Transformers, reactors, power supply units and combinations thereof delivered with or
incorporated in an appliance or equipment should follow the relevant EMC standard applicable
to that appliance or equipment. However, this standard may be used as a guide to test the
transformers, reactors, power supply units and combinations thereof separately before
incorporating them in the appliance or equipment.
This EMC standard covers performance 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 standard.
NOTE When EUT (Equipment under Test) is used, it covers transformers, reactors, power supply units and
combinations thereof where applicable.
This standard does not apply to:
– uninterruptible power supplies (UPS) covered by IEC 62040 series;
– power supply units covered by IEC 61204-3,
 (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, IEC 60065 and IEC
62368-1);
– power supplies and converters for use with or in products covered by IEC 61347-1.
