ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 2-5: Environment –
Description and classification of electromagnetic environments

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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a Technical Report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 61000-2-5, which is a technical report, has been prepared by technical committee 77:
Electromagnetic compatibility.
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 1995 and constitutes a
technical revision.
The significant technical changes with respect to the previous edition are the following:

– 8 – TR 61000-2-5  IEC:2011
– the description of the radiated electromagnetic environment has been done in more
detail and the considered interference sources have been updated;
– the concept of location classes has been reviewed and modified;
– the disturbance levels for the various location classes have been reviewed, modified
and the phenomena have been described in more detail.
The text of this Technical Report is based on the following documents:
Enquiry draft Report on voting
77/385/DTR 77/390/RVC
Full information on the voting for the approval of this Technical Report 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.
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.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 2-5: Environment –
Description and classification of electromagnetic environments

1 Scope and object
Knowledge of the electromagnetic environment that exists at locations where electrical and
electronic equipment and systems are intended to be operated is an essential precondition in
the process of achieving electromagnetic compatibility. This knowledge can be obtained by
various approaches, including a site survey of an intended location, the technical assessment
of the equipment and system as well as the general literature.
This part of IEC 61000
– introduces the concept of disturbance degrees and defines these for each
electromagnetic phenomena,
– classifies into various location classes and describes them by means of attributes,
– provides background information on the different electromagnetic phenomena that may
exist within the environment and
– compiles tables of compatibility levels for electromagnetic phenomena that are
considered to be relevant for those location classes.
This part of IEC 61000 is intended for guidance for those who are in charge of considering
and developing immunity requirements. It also gives basic guidance for the selection of
immunity levels. The data are applicable to any item of electrical or electronic equipment,
sub-system or system that operates in one of the locations as considered in this Technical
Report.
NOTE 1 It should be noted that immunity requirements and immunity levels determined for items of equipment
which are intended to be used at a certain location class are not inevitably bound to the electromagnetic
environment present at the location, but also to requirements of the equipment itself and the application in which it
is used (e.g. when taking into account requirements regarding availability, reliability or safety). These could lead to
more stringent requirements with respect to immunity levels or with respect to applicable performance criteria.
These levels may also be established for more general purposes such as in generic and product standards, taking
into account statistical and economic aspects as well as common experience in certain application fields.
NOTE 2 Electromagnetic phenomena in general show a broad range of parameters and characteristics and hence
cannot be related one-to-one to standardized immunity tests which basically reflect the impact of electromagnetic
phenomena by a well described test set-up. Nonetheless, this report follows an approach to correlate
electromagnetic phenomena and standardized immunity tests up to a certain extent. This might allow users of this
report to partly take into account standardized immunity tests such as given for example in the IEC 61000-4 series,
when specifying immunity requirements.
The descriptions of electromagnetic environments in this report are predominantly generic
ones, taking into account the characteristics of the location classes under consideration.
Hence, it should be kept in mind that there might be locations for which a more specific
description is required in order to conclude on immunity requirements applicable for those
specific locations.

3 Terms, definitions and abbreviated terms
3.1 Terms and definitions
For the purposes of this document the terms and definitions given in IEC 60050(161) as well
as the following apply
NOTE For brevity, instead of repeating the wording "device, equipment or system", the term "item" is used in this
report.
3.1.1
blackout
cutoff of electrical power, especially as a result of a shortage, a mechanical failure, or
overuse by consumers
NOTE A power cut due to a short or long-term electric power loss in an area.
3.1.2
brownout
reduction or cutback in electric power, especially as a result of a shortage, a mechanical
failure, or overuse by consumers
NOTE Reduction in the voltage of commercially supplied power. It is caused by the failure of the generation,
transmission, or distribution system, or deliberately by the power utility when demand exceeds supply. The
consumer may or may not notice the difference. In the worst case, damage may result.
3.1.3
burst
sequence of a limited number of distinct pulses or an oscillation of limited duration
[IEC 60050-161:1990, 161-02-07]
3.1.4
burst (in TDMA)
signals transmitted by a terminal in the form of a block of predetermined structure during a
time interval allotted to the terminal by a TDMA protocol
[IEC 60050-725:1994, 725-14-15]
3.1.5
characteristic impedance of a medium
wave impedance for a travelling wave in a specific medium
[IEC 60050-705:1995, 705-03-23, modified]
NOTE The characteristic impedance of a homogeneous isotropic medium is given by η = sqrt (µ/ε),
ι
where
µ is the permeability of the homogeneous isotropic medium, and
ε is the permittivity of the homogeneous isotropic medium.

3.1.6
(electromagnetic) compatibility level
specified electromagnetic disturbance level used as a reference level for co-ordination in the
setting of emission and immunity limits
[IEC 60050-161:1990, 161-03-10]
NOTE 1 By convention, the compatibility level is chosen so that there is only a small probability that it will be
exceeded by the actual disturbance level. However, electromagnetic compatibility is achieved only if emission and
immunity levels are controlled such that, at each location, the disturbance level resulting from the cumulative
emissions is lower than the mmunity level for each device, equipment and system situated at this same location.
NOTE 2 The compatibility level may be phenomenon, time or location dependent.
