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,
Electromagnetic compatibility – Guide to the drafting of electromagnetic compatibility publications.
Transformateurs, alimentations, bobines d’inductance et produits analogues - Exigences CEM
L'IEC 62041:2017 s’applique aux transformateurs, bobines d’inductance et aux blocs d’alimentation couverts par la série de normes IEC 61558. Le présent document traite des exigences de compatibilité électromagnétique pour l’émission et l’immunité dans la bande de fréquences comprise entre 0 Hz et 400 GHz. Aucun essai n’est nécessaire aux fréquences pour lesquelles aucune exigence n’est spécifiée. Cette troisième édition annule et remplace la deuxième édition parue en 2010. Elle constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
ajout d’un article sur les essais de production en série;
ajout d’un nouvel article sur l’incertitude des mesures, et
statut de norme harmonisée pour cette troisième édition.
Elle a le statut d’une norme CEM de famille de produits conformément au Guide IEC 107:2009,
Compatibilité électromagnétique – Guide pour la rédaction des publications sur la compatibilité électromagnétique.
La présente version bilingue (2018-01) correspond à la version anglaise monolingue publiée en 2017-08. La version française de cette norme n'a pas été soumise au vote.

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,
