Electromagnetic compatibility (EMC) - Part 6-4: Generic standards - Emission standard for industrial environments
IEC 61000-6-4:2018 for emission requirements applies to electrical and electronic equipment intended for use within the environment existing at industrial (see 3.1.12) locations. This document does not apply to equipment that fall within the scope of IEC 61000-6-3. The environments encompassed by this document cover both indoor and outdoor locations. Emission requirements in the frequency range 9 kHz to 400 GHz are covered in this document and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. No measurement needs to be performed at frequencies where no requirement is specified. These requirements are considered essential to provide an adequate level of protection to radio services. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the environments included within this document. Requirements are specified for each port considered. This generic EMC emission standard is to be used where no applicable product or product-family EMC emission standard is available. This third edition cancels and replaces the second edition published in 2006 and Amendment 1:2010 This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) possible future requirements on DC ports;
b) possible future radiated polarity specific emission limits within a FAR;
c) the definition of which average detector is used for emission measurements at frequencies above 1GHz and that results using a peak detector are acceptable for all measurements;
d) the definition of different EUT test arrangements.

Compatibilité électromagnétique (CEM) - Partie 6-4: Normes génériques - Norme sur l'émission pour les environnements industriels
L'IEC 61000-6-4:2018 concernant les exigences d'émissions s'applique aux appareils électriques et électroniques destinés à être utilisés dans des environnements existants (voir 3.1.12) sur des sites industriels. Le présent document ne s'applique pas aux appareils entrant dans le domaine d'application de l'IEC 61000-6-3. Les environnements couverts par le présent document sont les sites intérieurs et extérieurs. Les exigences en matière d'émission dans la plage de fréquences comprises entre 9 kHz et 400 GHz sont couvertes dans le présent document et ont été choisies de manière à assurer un niveau adéquat de protection de la réception radioélectrique dans l'environnement électromagnétique défini. Il n’est pas nécessaire de réaliser des mesures aux fréquences pour lesquelles aucune exigence n’a été spécifiée. Ces exigences sont considérées comme étant essentielles à l'obtention d'un niveau adéquat de protection des services radioélectriques. Tous les phénomènes perturbateurs n'ont pas été inclus pour les besoins de l'essai. Seuls l'ont été ceux considérés comme pertinents pour l'équipement destiné à fonctionner dans l'environnement couvert par le présent document. Les exigences sont spécifiées pour chacun des accès considérés. La présente Norme d'émission CEM générique doit être utilisée lorsqu’aucune norme d'émission CEM spécifique à un produit ou à une famille de produits n’est disponible. Cette troisième édition annule et remplace la seconde édition parue en 2016 et son Amendement 1:2010. Cette édition constitue une révision technique. La présente édition inclut les modifications techniques suivantes par rapport à l'édition précédente:
a) les exigences ultérieures possibles sur les accès en courant continu;
b) les limites futures possibles d'émissions rayonnées spécifiques à la polarité dans une FAR;
c) la définition du type de détecteur de valeur moyenne est utilisée pour les mesures des émissions à des fréquences supérieures à 1GHz et les résultats obtenus à l'aide d'un détecteur de crête sont acceptables pour tous les mesurages;
d) la définition des différentes dispositions d'essais de l’EUT.

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 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
has been made. Additions are in green text, deletions are in strikethrough red text.
International Standard IEC 61000-6-4 has been prepared by CISPR subcommittee H: Limits
for the protection of radio services.
This third edition cancels and replaces the second edition published in 2006 and
Amendment 1:2010 This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) possible future requirements on DC ports;
b) possible future radiated polarity specific emission limits within a FAR;
c) the definition of which average detector is used for emission measurements at frequencies
above 1GHz and that results using a peak detector are acceptable for all measurements;
d) the definition of different EUT test arrangements.
The text of this International Standard is based on the following documents:
FDIS Report on voting
CIS/H/339A/FDIS CIS/H/350/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
It forms Part 6-4 of the IEC 61000 series of standards. It has the status of a basic EMC
publication in accordance with IEC Guide 107.
