ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 4-9: Testing and measurement techniques –
Impulse magnetic field immunity test

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 61000-4-9 has been prepared by subcommittee 77B: High
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
It forms Part 4-9 of the IEC 61000 series. It has the status of a basic EMC publication in
accordance with IEC Guide 107.
This second edition cancels and replaces the first edition published in 1993 and Amendment
1:2000. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) new Annex B on induction coil field distribution;
b) new Annex D on measurement uncertainty;
c) new Annex E on mathematical modeling of surge waveform;

d) new Annex F on characteristics using two standard induction coils;
e) new Annex G on 3D numerical simulations;
f) coil factor calculation and calibration using current measurement have been addressed in
this edition.
The text of this standard is based on the following documents:
CDV Report on voting
77B/728/CDV 77B/745A/RVC

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.
A list of all parts in the IEC 61000 series, published under the general title Electromagnetic
compatibility (EMC), can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website 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.

Part 1: General
General considerations (introduction, fundamental principles)
Definitions, terminology
Part 2: Environment
Description of the environment
Classification of the environment

Part 4-9: Testing and measurement techniques –
Impulse magnetic field immunity test



1 Scope and object
This part of IEC 61000 specifies the immunity requirements, test methods, and range of
recommended test levels for equipment subjected to impulse magnetic disturbances mainly
encountered in:
– industrial installations,
– power plants,
– railway installations,
– medium voltage and high voltage sub-stations.
The applicability of this standard to equipment installed in different locations is determined by
the presence of the phenomenon, as specified in Clause 4.
This standard does not consider disturbances due to capacitive or inductive coupling in cables
or other parts of the field installation. Other IEC standards dealing with conducted
disturbances cover these aspects.
The object of this standard is to establish a common reference for evaluating the immunity of
electrical and electronic equipment when subjected to impulse magnetic fields. The test
method documented in this part of IEC 61000 describes a consi
