IEC 61000-6-4:2018 is also available as IEC 61000-6-4:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
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.

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.

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.

Part 6-4: Generic standards –
Emission standard for industrial environments
1 Scope

This part of IEC 61000 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.
NOTE 1 Safety considerations are not covered by this document.

NOTE 2 In special cases, situations will arise where the levels specified in this document will not offer adequate

protection; for example where a sensitive receiver is used in close proximity to an equipment. In these instances,

special mitigation measures may have to be employed.

NOTE 3 Disturbances generated in fault conditions of equipment are not covered by this document.

2 Normative references

The following documents are referred to in the text in such a way that some or all of their

content constitutes requirements of this document. For dated references, only the edition

fits in a cylindrical test volume of 1,2 m in diameter and 1,5 m above the ground plane

Note 1 to entry: These dimensions are currently under discussion in CISPR.
3.1.12
industrial location

location characterized by a separate power network, supplied from a high- or medium-voltage

transformer, dedicated for the supply of the installation

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.

Example locations include metalworking, pulp and paper, chemical plants, car production, farm building, high-

voltage areas of airports

Note 2 to entry: The connection between location and electromagnetic environment is given in 3.1.13.

3.1.13
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.
