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, 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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: Small power

transformers, reactors, power supply units and similar products.
This EMC standard covers only EMC aspects and is not a safety standard.
The text of this standard is based upon the following documents:
FDIS Report on voting
96/198/FDIS 96/210/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.

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.

The committee has decided that the contents of this publication will remain unchanged until

2007. At this date, the publication will be

EMC requirements
1 Scope

This international product family standard applies to independent transformers, reactors and

power supply units covered by IEC 60989 and the IEC 61558 series of standards. It prescribes

the electromagnetic compatibility requirements for emission and immunity in the frequency

range 0 Hz to 1 000 MHz.

Transformers, reactors and power supply units delivered with or incorporated in an appliance

or equipment shall comply with the relevant EMC standard applicable to that appliance or

equipment. However this standard may be used as a guide to test the transformers, reactors

and power supply units separately before incorporating them in the appliance or equipment.

This EMC standard covers only performance. Abnormal operation of the transformer, reactor

and power supply unit (e.g. simulated faults in the electric circuitry for testing purposes or

functional safety by influence of electromagnetic phenomena) are not taken into consideration

in this standard.

NOTE When the term transformer is used, it covers transformers, reactors and power supplies where applicable.

This standard does not apply to:
– motor-generator sets;
– uninterruptible power supplies (UPS) covered by IEC 62040;
– 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, IEC 61010-1, IEC 60601-1 and IEC 60065);
– step-down converters covered by IEC61347-1 and 61347-2-2;

– power supplies and converters for use with or in products covered by IEC 61347-2-2.

The following referenced documents are indispensable for the application of this document. For

dated references, only the edition cited applies. For undated references, the latest edition of

the referenced document (including any amendments) applies.
