ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 4-2: Testing and measurement techniques –
Electrostatic discharge 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 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 61000-4-2 has been prepared by subcommittee 77B: High-
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This second edition cancels and replaces the first edition published in 1995, its amendment 1
(1998) and its amendment 2 (2000) and constitutes a technical revision.
It forms Part 4-2 of IEC 61000. It has the status of a basic EMC publication in accordance
with IEC Guide 107.
The main changes with respect to the first edition of this standard and its amendments are the
following:
• the specifications of the target have been extended up to 4 GHz. An example of target
matching these requirements is also provided;

---------------------- Page: 10 ----------------------

• information on radiated fields from human-metal discharge and from ESD generators
is provided;
• measurement uncertainty considerations with examples of uncertainty budgets are
given too.
The text of this standard is based on the following documents:
FDIS Report on voting
77B/574/FDIS 77B/584/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.
A list of all parts of 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 maintenance result 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.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 4-2: Testing and measurement techniques –
Electrostatic discharge immunity test



1 Scope
This part of IEC 61000 relates to the immunity requirements and test methods for electrical
and electronic equipment subjected to static electricity discharges, from operators directly,
and from personnel to adjacent objects. It additionally defines ranges of test levels which
relate to different environmental and installation conditions and establishes test procedures.
The object of this standard is to establish a common and reproducible basis for evaluating the
performance of electrical and electronic equipment when subjected to electrostatic
discharges. In addition, it includes electrostatic discharges which may occur from personnel to
objects near vital equipment.
This standard defines:
– typical waveform of the discharge current;
– range of test levels;
– test equipment;
– test setup;
– test procedure;
– calibration procedure;
– measurement uncertainty.
This standard gives specifications for test performed in "laboratories" and "post-installation
tests" performed on equipment in the final installation.
This standard does not intend to specify the tests to be applied to particular apparatus or
systems. Its main aim is to give a general basic reference to all concerned product
committees of the IEC. The product committees (or users and manufacturers of equipment)
remain responsible for the appropriate choice of the tests and the severity level to be applied
to their equipment.
In order not to impede the task of coordination and standardization, the product committees or
users and manufacturers are strongly recommended to consider (in their future work or
revision of old standards) the adoption of the relevant immunity tests specified in this
standard.
