Electromagnetic compatibility (EMC) - Part 6-4: Generic standards - Emission standard for industrial environments

This part of IEC 61000 for EMC emission requirements applies to electrical and electronic apparatus intended for use in industrial environments as described below. Emission requirements in the frequency range 0 Hz to 400 GHz are covered. No measurement needs to be performed at frequencies where no requirement is specified. This generic EMC emission standard is applicable if no relevant dedicated product or product-family EMC emission standard exists. This standard applies to a 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 examples: - industrial, scientific and medical (ISM) apparatus; - heavy inductive or capacitive loads that are frequently switched; - high currents and associated magnetic fields. The object of this standard is to define the emission test requirements for apparatus defined in the scope in relation to continuous and transient, conducted and radiated disturbances. The emission requirements have been selected so as to ensure that disturbances generated by apparatus operating normally in industrial locations do not exceed a level that could prevent other apparatus from operating as intended. Fault conditions of apparatus are not taken into account. 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 requirements represent essential electromagnetic compatibility emission requirements. Requirements are specified for each port considered.

Compatibilité électromagnétique (CEM) - Partie 6-4: Normes génériques - Norme sur l'émission pour les environnements industriels

La présente partie de la CEI 61000 pour les exigences d'émissions CEM s'applique aux appareils électriques et électroniques destinés à être utilisés dans des environnements industriels, tels qu'ils sont décrits ci-dessous. Les exigences d'émissions dans la gamme de fréquences de 0 kHz à 400 GHz sont couvertes. Il n'est pas nécessaire de réaliser des mesures aux fréquences pour lesquelles aucune exigence n'a été spécifiée. Cette norme d'émission CEM générique s'applique en l'absence de norme applicable d'émission CEM 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'un ou plusieurs des exemples suivants: - présence d'appareils industriels, scientifiques et médicaux (ISM); - commutations fréquentes de charges inductives ou capacitives importantes; - intensités et champs magnétiques associés importants. L'objet de cette norme est de définir les exigences d'essais d'émissions aux perturbations continues et transitoires, conduites et rayonnées, pour les appareils définis dans le domaine d'application. Les exigences des perturbations émises ont été choisies de manière à assurer que les perturbations engendrées par l'appareil en fonctionnement normal, dans un environnement industriel, ne dépassent pas un niveau qui pourrait empêcher d'autres appareils de fonctionner comme prévu normalement. Les conditions de défaut de l'appareil ne sont pas prises en compte. 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 représentent les exigences essentielles de compatibilité électromagnétique concernant les émissions. Les exigences sont spécifiées pour chacun des accès considérés.

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 61000-6-4 has been prepared by CISPR subcommittee H: Limits for
the protection of radio services.
This second edition cancels and replaces the first edition published in 1997. It constitutes a
technical revision. The major changes in this edition are the inclusion of a clause on tests for
equipment in series production, a new clause on measurement uncertainty and the inclusion of
requirements on telecommunications ports. The informative annex has been deleted.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-4: Generic standards – Emission standard

for industrial environments
1 Scope and object
This part of IEC 61000 for EMC emission requirements applies to electrical and electronic
apparatus intended for use in industrial environments as described below.
Emission requirements in the frequency range 0 Hz to 400 GHz are covered. No measurement
needs to be performed at frequencies where no requirement is specified.
This generic EMC emission standard is applicable if no relevant dedicated product or product-
family EMC emission standard exists.
This standard applies to a 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 examples:
1)
– industrial, scientific and medical (ISM) ) apparatus;
– heavy inductive or capacitive loads that are frequently switched;
– high currents and associated magnetic fields.
The object of this standard is to define the emission test requirements for apparatus defined in
the scope in relation to continuous and transient, conducted and radiated disturbances.
The emission requirements have been selected so as to ensure that disturbances generated by
apparatus operating normally in industrial locations do not exceed a level that could prevent
other apparatus from operating as intended. Fault conditions of apparatus are not taken into
account. 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 requirements represent essential electromagnetic compatibility emission requirements.
Requirements are specified for each port considered.
NOTE 1 Safety considerations are not covered by this standard.
NOTE 2 In special cases, situations will arise where the levels specified in this standard will not offer adequate
protection; for example where a sensitive receiver is used in close proximity to an apparatus. In these instances,
special mitigation measures may have to be employed.

de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.

9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de la CEI peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. La CEI ne saurait être tenue pour
responsable de ne pas avoir identifié de tels droits de propriété et de ne pas avoir signalé leur existence.
La norme internationale CEI 61000-6-4 a été préparée par le sous-comité H du CISPR: Limites
pour la protection des services radioélectriques.
Cette deuxième édition annule et remplace la première édition parue en 1997. Cette édition
constitue une révision technique. Les principaux changements introduits par cette nouvelle
édition consistent dans l’ajout de deux nouveaux articles, le premier sur les essais applicables

1 Domaine d’application et objet

La présente partie de la CEI 61000 pour les exigences d’émissions CEM s’applique aux

appareils électriques et électroniques destinés à être utilisés dans des environnements
industriels, tels qu'ils sont décrits ci-dessous.
Les exigences d’émissions dans la gamme de fréquences de 0 kHz à 400 GHz sont couvertes.
Il n’est pas nécessaire de réaliser des mesures aux fréquences pour lesquelles aucune
exigence n’a été spécifiée.
Cette norme d’émission CEM générique s'applique en l'absence de norme applicable
d’émission CEM 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’un ou plusieurs des exemples
suivants:
1)
– présence d'appareils industriels, scientifiques et médicaux (ISM) ;
– commutations fréquentes de charges inductives ou capacitives importantes;
– intensités et champs magnétiques associés importants.
L'objet de cette norme est de définir les exigences d'essais d’émissions aux perturbations
continues et transitoires, conduites et rayonnées, pour les appareils définis dans le domaine
d'application.
Les exigences des perturbations émises ont été choisies de manière à assurer que les
perturbations engendrées par l’appareil en fonctionnement normal, dans un environnement

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-4: Generic standards – Emission 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 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 61000-6-4 has been prepared by CISPR subcommittee H: Limits for
the protection of radio services.
This second edition cancels and replaces the first edition published in 1997. It constitutes a
technical revision. The major changes in this edition are the inclusion of a clause on tests for
equipment in series production, a new clause on measurement uncertainty and the inclusion of
requirements on telecommunications ports. The informative annex has been deleted.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-4: Generic standards – Emission standard

for industrial environments
1 Scope and object
This part of IEC 61000 for EMC emission requirements applies to electrical and electronic
apparatus intended for use in industrial environments as described below.
Emission requirements in the frequency range 0 Hz to 400 GHz are covered. No measurement
needs to be performed at frequencies where no requirement is specified.
This generic EMC emission standard is applicable if no relevant dedicated product or product-
family EMC emission standard exists.
This standard applies to a 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.

INTERPRETATION SHEET
This interpretation sheet has been prepared by CISPR subcommittee H: Limits for the
protection of radio services, of IEC technical committee CISPR: International special
committee on radio interference.
The text of this interpretation sheet is based on the following documents:
FDIS Report on voting
CISPR/H/218/FDIS CISPR/H/223/RVD

Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.
___________
Interpretation
The requirement in Clause 8 “Measurement uncertainty” of IEC 61000-6-4 Amend. 1 ed. 2.0:
8 Measurement uncertainty
The measurement instrumentation uncertainty shall be determined according to CISPR
16-4-2, where applicable.
NOTE For a given test method, the actual value of U has only to be recorded in the test report if the
lab
value is greater than U .
CISPR
shall be interpreted as follows:
The measurement instrumentation uncertainty shall be calculated and compared with the

budgets defined in CISPR 16-4-2. For each applicable test method, whose instrumentation
uncertainty budgets are higher than those defined in CISPR 16-4-2, compliance with the limits
has to be determined according to CISPR 16-4-2 methodology. This requirement is only
applicable for tests where an uncertainty budget is defined in CISPR 16-4-2.
The additional note was further clarification that there is no need to state in the test report the
laboratory uncertainty budget U if this is less than or equal to the U defined in CISPR
lab CISPR
16-4-2. However, it has to be mentioned in the test report that the instrumentation
measurement uncertainty is determined according to CISPR 16-4-2.

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
