Electromagnetic compatibility (EMC) - Part 6-2: Generic standards - Immunity for industrial environments

applies to electrical and electronic apparatus intended for use in industrial environments, as described below. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies where no requirements are specified. This generic EMC immunity standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists. This standard applies to apparatus intended to be connected to a power network supplied from a high or medium voltage transformer dedicated to the supply of an installation feeding manufacturing or similar plant, and intended to operate in or in proximity to industrial locations, as described below. This standard applies also to apparatus which is battery operated and intended to be used in industrial locations. The environments encompassed by this standard are industrial, both indoor and outdoor. The immunity requirements have been selected to ensure an adequate level of immunity for apparatus at industrial locations. The levels do not, however, cover extreme cases, which may occur at any location, but with an extremely low probability of occurrence. Not all disturbance phenomena have been included for testing purposes in this standard, but only those considered as relevant for the equipment covered by this standard. These test requirements represent essential electromagnetic compatibility immunity requirements.

Compatibilité électromagnétique (CEM) - Partie 6-2: Normes génériques - Immunité pour les environnements industriels

S'applique aux appareils électriques et électroniques destinés à être utilisés dans des environnements industriels, tels qu'ils sont décrits ci-dessous. Cette partie couvre les exigences d'immunité dans la gamme de fréquences de 0 kHz à 400 GHz. Il n'est pas nécessaire de réaliser des essais aux fréquences pour lesquelles aucune exigence n'est spécifiée. Cette norme générique d'immunité CEM s'applique en l'absence de norme d'immunité CEM applicable spécifique à un produit ou à une famille de produits. Les appareils couverts par cette norme sont destinés à être raccordés à un réseau d'énergie alimenté par un transformateur haute tension ou moyenne tension réservé à l'alimentation d'une l'installation alimentant un site industriel ou analogue, et destinés à fonctionner à l'intérieur ou à proximité des sites industriels, comme défini ci-dessous. Cette norme s'applique également aux appareils qui sont alimentés par piles ou accumulateurs et qui sont destinés à être utilisés dans des sites industriels. Les environnements couverts par cette norme sont les environnements industriels, intérieurs et extérieurs. Les exigences d'immunité ont été choisies pour assurer un niveau adéquat d'immunité pour les appareils utilisés sur des sites industriels. Ces niveaux ne couvrent pas cependant les cas extrêmes qui peuvent apparaître, mais avec une très faible probabilité, sur un site quelconque. Cette norme ne comporte pas, pour les besoins des essais, tous les phénomènes perturbateurs mais uniquement ceux considérés comme applicables pour les appareils couverts par la norme. Ces exigences d'essais représentent les exigences essentielles de compatibilité électromagnétique concernant l'immunité.

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 61000-6-2 has been prepared by IEC technical committee 77:
Electromagnetic compatibility.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-2: Generic standards –
Immunity for industrial environments

1 Scope and object
This part of IEC 61000 for EMC immunity requirements applies to electrical and electronic
apparatus intended for use in industrial environments, as described below. Immunity
requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be
performed at frequencies where no requirements are specified.
This generic EMC immunity standard is applicable if no relevant dedicated product or
product-family EMC immunity standard exists.
This standard applies to apparatus intended to be connected to a power network supplied
from a high or medium voltage transformer dedicated to the supply of an installation feeding
manufacturing or similar plant, and intended to operate in or in proximity to industrial
locations, as described below. This standard applies also to apparatus which is battery
operated and intended to be used in industrial locations.
The environments encompassed by this standard are industrial, both indoor and outdoor.
Industrial locations are in addition characterised by the existence of one or more of the
following:
– industrial, scientific and medical (ISM) apparatus (as defined in CISPR 11);
– heavy inductive or capacitive loads are frequently switched;
– currents and associated magnetic fields are high.
The object of this standard is to define immunity test requirements for apparatus defined in
the scope in relation to continuous and transient, conducted and radiated disturbances,
including electrostatic discharges.
The immunity requirements have been selected to ensure an adequate level of immunity for
apparatus at industrial locations. The levels do not, however, cover extreme cases, which
may occur at any location, but with an extremely low probability of occurrence. Not all
disturbance phenomena have been included for testing purposes in this standard, but only

those considered as relevant for the equipment covered by this standard. These test
requirements represent essential electromagnetic compatibility immunity requirements.
NOTE 1 Information on other disturbance phenomena is given in IEC 61000-4-1.
Test requirements are specified for each port considered.
NOTE 2 Safety considerations are not covered by this standard.
NOTE 3 In special cases, situations will arise where the level of disturbances may exceed the levels specified in
this standard e.g. where an apparatus is installed in proximity to ISM equipment as defined in CISPR 11 or where
a hand-held transmitter is used in close proximity to an apparatus. In these instances, special mitigation measures
may have to be employed.
61000-6-2  IEC:2005 – 13 –
NOTE 4 The industrial environment may be changed by special mitigation measures. Where such measures can

be shown to produce an electromagnetic environment equivalent to the residential, commercial or light-industrial
environment, then the generic standard for this environment, or the relevant product standard, should be applied.

Immunité pour les environnements industriels

1 Domaine d'application et objet

La présente partie de la CEI 61000 concernant les exigences d'immunité en matière de
compatibilité électromagnétique s'applique aux appareils électriques et électroniques
destinés à être utilisés dans des environnements industriels, tels qu'ils sont décrits ci-
dessous. Cette partie couvre les exigences d’immunité dans la gamme de fréquences de 0
kHz à 400 GHz. Il n’est pas nécessaire de réaliser des essais aux fréquences pour lesquelles
aucune exigence n’est spécifiée.
Cette norme générique d'immunité CEM s'applique en l'absence de norme d'immunité CEM
applicable spécifique à un produit ou à une famille de produits.
Les appareils couverts par cette norme sont destinés à être raccordés à un réseau d'énergie
alimenté par un transformateur haute tension ou moyenne tension réservé à l'alimentation
d'une l'installation alimentant un site industriel ou analogue, et destinés à fonctionner à
l’intérieur ou à proximité des sites industriels, comme défini ci-dessous. Cette norme
s'applique également aux appareils qui sont alimentés par piles ou accumulateurs et qui sont
destinés à être utilisés dans des sites industriels.
Les environnements couverts par cette norme sont les environnements industriels, intérieurs
et extérieurs.
Les sites industriels sont en outre caractérisés par l’existence d’une ou plusieurs des
conditions suivantes:
– appareils industriels, scientifiques et médicaux (ISM) (définis dans la CISPR 11);
– commutations fréquentes de charges inductives ou capacitives importantes;
– valeurs élevées des courants et des champs magnétiques associés.
L'objet de cette norme est de définir les exigences d'essais d'immunité aux perturbations
continues et transitoires, conduites et rayonnées, y compris aux décharges électrostatiques,
pour les appareils définis dans le domaine d'application.

Les exigences d'immunité ont été choisies pour assurer un niveau adéquat d'immunité pour
les appareils utilisés sur des sites industriels. Ces niveaux ne couvrent pas cependant les
cas extrêmes qui peuvent apparaître, mais avec une très faible probabilité, sur un site

essentielles de compatibilité électromagnétique concernant l'immunité.
NOTE 1 Des informations sur d’autres phénomènes perturbateurs sont fournies dans la CEI 61000-4-1.
Les exigences sont spécifiées pour chaque accès considéré.
NOTE 2 Cette norme ne traite pas des aspects de sécurité.
NOTE 3 Dans des cas spéciaux, des situations apparaîtront dans lesquelles les niveaux de perturbation peuvent
dépasser les niveaux spécifiés dans cette norme, par exemple lorsqu'un appareil est installé à proximité d'un
appareil ISM tel que défini dans la CISPR 11 ou lorsqu’un émetteur portatif est utilisé très près d’un appareil. Dans
ces cas, il peut être nécessaire de prendre des mesures particulières d’atténuation.

Immunity for industrial 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 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 61000-6-2 has been prepared by IEC technical committee 77:
Electromagnetic compatibility.
This second edition cancels and replaces the first edition published in 1999. It constitutes a
technical revision. Specific technical changes have been introduced to Tables 1 to 4. The
frequency range for tests according to IEC 61000-4-3 has been extended above 1 GHz
according to technologies used in this frequency area. The use of TEM waveguide testing
according to IEC 61000-4-20 has been introduced for certain products and the testing
requirements according to IEC 61000-4-11 have been amended significantly.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-2: Generic standards –
Immunity for industrial environments

1 Scope and object
This part of IEC 61000 for EMC immunity requirements applies to electrical and electronic
apparatus intended for use in industrial environments, as described below. Immunity
requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be
performed at frequencies where no requirements are specified.
This generic EMC immunity standard is applicable if no relevant dedicated product or
product-family EMC immunity standard exists.
This standard applies to apparatus intended to be connected to a power network supplied
from a high or medium voltage transformer dedicated to the supply of an installation feeding
manufacturing or similar plant, and intended to operate in or in proximity to industrial
locations, as described below. This standard applies also to apparatus which is battery
operated and intended to be used in industrial locations.
The environments encompassed by this standard are industrial, both indoor and outdoor.
Industrial locations are in addition characterised by the existence of one or more of the
following:
– industrial, scientific and medical (ISM) apparatus (as defined in CISPR 11);
– heavy inductive or capacitive loads are frequently switched;
– currents and associated magnetic fields are high.
The object of this standard is to define immunity test requirements for apparatus defined in
the scope in relation to continuous and transient, conducted and radiated disturbances,
including electrostatic discharges.
The immunity requirements have been selected to ensure an adequate level of immunity for
apparatus at industrial locations. The levels do not, however, cover extreme cases, which
may occur at any location, but with an extremely low probability of occurrence. Not all
disturbance phenomena have been included for testing purposes in this standard, but only
those considered as relevant for the equipment covered by this standard. These test
requirements represent essential electromagnetic compatibility immunity requirements.
NOTE 1 Information on other disturbance phenomena is given in IEC 61000-4-1.
Test requirements are specified for each port considered.
NOTE 2 Safety considerations are not covered by this standard.
NOTE 3 In special cases, situations will arise where the level of disturbances may exceed the levels specified in
this standard e.g. where an apparatus is installed in proximity to ISM equipment as defined in CISPR 11 or where
a hand-held transmitter is used in close proximity to an apparatus. In these instances, special mitigation measures
may have to be employed.
61000-6-2 © IEC:200561000-6-2  IEC:2005 – 13 – – 7 –
NOTE 4 The industrial environment may be changed by special mitigation measures. Where such measures can
be shown to produce an electromagnetic environment equivalent to the residential, commercial or light-industrial
environment, then the generic standard for this environment, or the relevant product standard, should be applied.

4 Performance criteria
The variety and the diversity of the apparatus within the scope of this standard makes it
difficult to define precise criteria for the evaluation of the immunity test results.
If, as a result of the application of the tests defined in this standard, the apparatus becomes
dangerous or unsafe, the apparatus shall be deemed to have failed the test.
A functional description and a definition of performance criteria, during or as a consequence
of the EMC testing, shall be provided by the manufacturer and noted in the test report, based
on one of the following criteria for each test as specified in Tables 1 to 4:

61000-6-2 © IEC:200561000-6-2  IEC:2005 – 17 – – 9 –
a) Performance criterion A: The apparatus shall continue to operate as intended during
and after the test. No degradation of performance or loss of function is allowed below a
performance level specified by the manufacturer, when the apparatus is used as
intended. The performance level may be replaced by a permissible loss of performance. If
the minimum performance level or the permissible performance loss is not specified by
the manufacturer, either of these may be derived from the product description and
documentation and what the user may reasonably expect from the apparatus if used as
intended.
b) Performance criterion B: The apparatus shall continue to operate as intended after the
test. No degradation of performance or loss of function is allowed below a performance
level specified by the manufacturer, when the apparatus is used as intended. The
performance level may be replaced by a permissible loss of performance. During the test,
degradation of performance is however allowed. No change of actual operating state or
stored data is allowed. If the minimum performance level or the permissible performance
loss is not specified by the manufacturer, either of these may be derived from the product
description and documentation and what the user may reasonably expect from the
apparatus if used as intended.
c) Performance criterion C: Temporary loss of function is allowed, provided the function is
self-recoverable or can be restored by the operation of the controls.
5 Conditions during testing
The equipment under test (EUT) shall be tested in the expected most susceptible operating
mode e.g. identified by performing limited pre-tests. This mode shall be consistent with
normal applications. The configuration of the test sample shall be varied to achieve maximum
susceptibility consistent with typical applications and installation practice.
If the apparatus is part of a system, or can be connected to auxiliary apparatus, the
apparatus shall be tested while connected to the minimum representative configuration of
auxiliary apparatus necessary to exercise the ports in a similar manner to that described in
CISPR 22.
In cases where a manufacturer's specification requires external protection devices or
measures which are clearly specified in the user's manual, the test requirements of this
standard shall be applied with the external protection devices or measures in place.
The configuration and mode of operation during the tests shall be precisely noted in the test
report. It is not always possible to test every function of the apparatus; in such cases the
most critical mode(s) of operation shall be selected.
If the apparatus has a large number of similar ports or ports with many similar connections, a
sufficient number shall be selected to simulate actual operating conditions and to ensure that
all the different types of termination are covered.
The tests shall be carried out at one single set of parameters within the operating ranges of
temperature, humidity and atmospheric pressure specified for the product and at the rated
supply voltage, unless otherwise indicated in the basic standard.
6 Product documentation
If the manufacturer is using his own specification for an acceptable level of EMC performance
or degradation of EMC performance during or after the testing required by this standard, this
specification shall be provided in the product documentation available to the user.

61000-6-2  IEC:2005 – 19 – – 10 – 61000-6-2 © IEC:2005
7 Applicability
The application of tests for evaluation of immunity depends on the particular apparatus, its
configuration, its ports, its technology and its operating conditions.
Tests shall be applied to the relevant ports of the apparatus according to Tables 1 to 4. Tests
shall only be carried out where the relevant ports exist.
It may be determined from consideration of the electrical characteristics and usage of a
particular apparatus that some of the tests are inappropriate and, therefore, unnecessary. In
such a case, it is required that the decision and justification not to test be recorded in the test
report.
8 Immunity test requirements
The immunity test requirements for apparatus covered by this standard are given on a port by
port basis.
Tests shall be conducted in a well-defined and reproducible manner.
The tests shall be carried out individually as single tests in sequence. The tests may be
performed in any order.
The description of the test, relevant generator, appropriate methods, and the set-up to be
used are given in basic standards, which are referred to in the following tables.
The contents of these basic standards are not repeated here, however modifications or
additional information needed for the practical application of the tests are given in this
standard.
