Immunity standard 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 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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change

ELECTROMAGNETIC COMPATIBILITY (EMC) –

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

1 Scope and object
This part of IEC 61000 for EMC immunity requirements applies to electrical and electronic
apparatus equipment intended for use in industrial environments locations, 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 electrical and electronic equipment intended to be
operated in or in proximity to industrial locations, as described below defined in 3.7, both
indoor and outdoor.
This standard applies also to apparatus equipment intended to be directly connected to a DC
distribution network or 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 defines the immunity test requirements for apparatus
defined equipment specified 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 equipment operating within 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. They are specified for each port considered.
NOTE 1 Information on other disturbance phenomena is given in IEC TR 61000-4-1.
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, for example where an apparatus equipment is installed in proximity to industrial, scientific and
medical equipment as defined in CISPR 11 or where a hand-held transmitter is used in close proximity to an
apparatus equipment. In these instances, special mitigation measures may have to be employed.

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 may be applied.

For the purposes of this document, the terms and definitions given in IEC 60050-161 as well
as the following apply.
NOTE Additional definitions related to EMC and to relevant phenomena are given in other IEC and CISPR
publications.
3.1
port
particular interface of the specified apparatus equipment which couples this equipment with or
is influenced by the external electromagnetic environment (see Figure 1)
Note 1 to entry: In some cases different ports may be combined. Examples of ports of interest are shown in
Figure 1. The enclosure port is the physical boundary of the equipment (e.g. enclosure). The enclosure port
provides for radiated and electrostatic discharge (ESD) energy transfer, whereas the other ports provide for
conducted energy transfer, either by direct injection or by induction.

physical boundary of the apparatus equipment through which electromagnetic fields may
radiate through or on which they may impinge on
3.3
cable port
port at which a conductor or a cable is connected to the apparatus
NOTE Examples are signal and power ports.
3.3
signal/control port
port at which a conductor or cable intended to carry signals is connected to the apparatus
equipment
NOTE EXAMPLE Analog inputs, outputs and control lines; data buses; communication networks lines, etc.

3.4
power port
port at which a conductor or cable, carrying the primary electrical input/output power needed
for the operation (functioning) of an apparatus or associated apparatus is connected to the
apparatus equipment
3.5
long distance lines
lines connected to a signal/control port and which inside a building are is longer than 30 m, or
which leaves the building (including lines of outdoor installations a line installed outdoors)
3.6
DC distribution network
local DC electricity supply network in the infrastructure of a certain site or building intended
for flexible use by one or more different types of equipment and ensuring continuous power
supply independently from the conditions of the public mains network
Note 1 to entry: Connection to a remote local battery is not regarded as a DC distribution network, if such a link
comprises only power supply for a single piece of equipment.
3.7
industrial location
location characterized by a separate power network, supplied from a high- or medium-voltage
transformer, dedicated for the supply of the installation
EXAMPLE Metalworking, pulp and paper, chemical plants, car production, farm building, high-voltage areas of
airports.
Note 1 to entry: Industrial locations can generally be described by the existence of an installation with one or
more of the following characteristics:
– items of equipment installed and connected together and working simultaneously;
– significant amount of electrical power generated, transmitted and/or consumed;
– frequent switching of heavy inductive or capacitive loads;
– high currents and associated magnetic fields;
– presence of industrial, high power scientific and medical (ISM) equipment (for example, welding machines).
The electromagnetic environment at an industrial location is predominantly produced by the equipment and
installation present at the location. There are types of industrial locations where some of the electromagnetic
phenomena appear in a more severe degree than in other installations.
Note 2 to entry: The connection between location and electromagnetic environment is given in 3.8.
3.8
electromagnetic environment
totality of electromagnetic phenomena existing at a given location
Note 1 to entry: In general, the electromagnetic environment is time-dependent and its description may need a
statistical approach.
Note 2 to entry: It is very important not to confuse the electromagnetic environment and the location itself.

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 specific performance criteria, during or as a
consequence of the EMC immunity testing of equipment under test (EUT), shall be provided
by the manufacturer and noted in the test report, based on. They shall be consistent with one
of the following general criteria for each test as specified in Table 1 to Table 4:
a) Performance criterion A: The apparatus EUT 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 EUT 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 this may be derived from the product description and
documentation and what the user may reasonably expect from the apparatus equipment if
used as intended.
b) Performance criterion B: The apparatus EUT 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 EUT is used as
intended. The performance level may be replaced by a permissible loss of performance.
However, during the test, degradation of performance is allowed but 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 equipment if used as intended.
c) Performance criterion C: Temporary loss of function is allowed during the test, provided
the function is self-recoverable or can be restored by the operation of the controls.
If, as a result of the application of the tests defined in this standard, the EUT becomes
dangerous or unsafe, it shall be deemed to have failed the test.
5 Conditions during testing
The equipment under test (EUT) shall be tested in the expected most susceptible operating
mode, for example 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. The
configuration and mode of operation during the tests shall be precisely noted in the test
report.
If the apparatus equipment is part of a system, or can be connected to auxiliary apparatus
equipment, the apparatus equipment shall be tested while connected to the minimum
representative configuration of auxiliary equipment necessary to exercise the ports in a similar
manner to that described in CISPR 22. Auxiliary equipment may be simulated.
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 equipment 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. Justification for the selection
of the tested ports shall be included in the test report.
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 fact shall be provided stated in the product user documentation available to the
user. This specification itself shall be made available upon request.
7 Applicability
The application of tests for evaluation of immunity depends on the particular apparatus
equipment, its configuration, its ports, its technology and its operating conditions.
Tests shall be applied to the relevant ports of the apparatus equipment according to Table 1
to Table 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 equipment 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 shall
be recorded in the test report.
8 Measurement uncertainty
Where guidance for the assessment of the instrumentation uncertainty of an immunity test is
specified in IEC TR 61000-1-6 or in the corresponding basic standard, this should be
followed.
9 Immunity test requirements
The immunity test requirements for apparatus equipment covered by this standard are given
on a port by port basis and listed in Table 1 to Table 4.
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. Identical units may be used for testing in parallel, and this information
shall be recorded in the test report.
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 Table 1 to Table 4.
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.

Annex A
(informative)
Guidance for product committees
According to IEC Guide 107 generic immunity standards specify a set of requirements, test
procedures and generalized performance criteria applicable to such products or systems
intended to be operated at locations having the respective electromagnetic environment. The
normative part of this document defines a minimum set of immunity requirements for
equipment operating at locations in industrial environments.
However, there are electromagnetic phenomena which are expected to occur or increase in
the future which might be relevant for some products or product families or interference
cases. EMC committees should provide advice and support to the product committees in
setting of corresponding immunity levels.
The purpose of Annex A is to indicate tests which might be relevant for such future situations
or for some products or product families. The product committees are requested to consider
those tests and test levels given in Table A.1. As these tests are not formally referenced in
this standard they are not needed for demonstrating compliance with this standard.
