IEC 61000-6-3:2020

Electromagnetic compatibility (EMC) - Part 6-3: Generic standards - Emission standard for equipment in residential environments

IEC 61000-6-3:2020 is a generic EMC emission standard applicable only if no relevant dedicated product or product family EMC emission standard has been published. This part of IEC 61000 for emission requirements applies to electrical and electronic equipment intended for use at residential (see 3.1.14) locations. This part of IEC 61000 also applies to electrical and electronic equipment intended for use at other locations that do not fall within the scope of IEC 61000-6-8 or IEC 61000-6-4. The intention is that all equipment used in the residential, commercial and light-industrial environments are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 apply. The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this document. The emission requirements in this document are not intended to be applicable to the intentional transmissions and their harmonics from a radio transmitter as defined by the ITU. This third edition cancels and replaces the second edition published in 2006 and its Amendment 1:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) alternative method for measuring conducted emissions on DC ports;
b) limits and requirements applicable only to equipment intended to be used in residential locations;
c) more stringent limits for DC power ports.
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 can be employed. NOTE 3 Disturbances generated in fault conditions of equipment are not covered by this document.
NOTE 4 As the requirements in this document are more stringent or equivalent to those requirements in IEC 61000-6-4 and IEC 61000-6-8, equipment fulfilling the requirements of this document comply with the requirements of IEC 61000-6-4 and IEC 61000-6-8.

Compatibilité électromagnétique (CEM) - Partie 6-3: Normes génériques - Norme sur l'émission relative aux appareils utilisés dans les environnements résidentiels

IEC 61000-6-3:2020 est une norme d’émissions CEM générique relative aux émissions eapplique uniquement si aucune norme CEM d’émission pertinente dédiée à un produit ou une famille de produits n’a été publiée. La présente partie de l'IEC 61000 concernant les exigences d'émissions s'applique aux appareils électriques et électroniques destinés à être utilisés dans des environnements résidentiels (voir 3.1.14). La présente partie de l'IEC 61000 s'applique également aux appareils électriques et électroniques destinés à être utilisés dans des environnements n’entrant pas dans le domaine d'application de l’IEC 61000-6-8 ou de l’IEC 61000-6-4. L'objectif est que tous les appareils utilisés dans les environnements résidentiels, commerciaux et de l'industrie légère soient couverts par l’IEC 61000-6-3 ou l’IEC 61000-6-8. Les exigences dans l’IEC 61000-6-3 s'appliquent en présence du moindre doute. Les exigences en matière d’émissions conduites et rayonnées dans la plage de fréquences jusqu'à 400 GHz sont considérées comme essentielles et ont été choisies de manière à assurer un niveau adéquat de protection de la réception radioélectrique dans l'environnement électromagnétique défini. Tous les phénomènes de perturbation n'ont pas été inclus pour les besoins de l'essai. Seuls l'ont été ceux considérés comme pertinents pour les appareils destinés à fonctionner dans l'environnement couvert par le présent document. Les exigences du présent document relatives à l’émission ne sont pas destinées à s'appliquer aux transmissions intentionnelles et à leurs harmoniques depuis un émetteur radio tel que défini par l'UIT. Cette troisième édition annule et remplace la deuxième édition parue en 2006 et l'Amendement 1:2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) méthode alternative de mesurage des émissions conduites sur les accès en courant continu;
b) limites et exigences applicables uniquement sur les matériels destinés à être utilisés dans des environnements résidentiels;
c) limites plus strictes en ce qui concerne les accès d'alimentation en courant continu.
NOTE 1 Le présent document ne traite pas des aspects liés à la sécurité.
NOTE 2 Dans certains cas particuliers, des situations sont susceptibles de se produire, pour lesquelles les niveaux spécifiés dans le présent document n’offrent pas le niveau de protection adéquat; par exemple lorsqu'un récepteur sensible est utilisé très proche d'un appareil. Dans de tels cas, des mesures particulières d'atténuation peuvent être employées.
NOTE 3 Les perturbations générées dans les conditions de défaut de l'appareil ne sont pas couvertes par le présent document.
NOTE 4 Les exigences du présent document étant plus sévères ou équivalentes à celles de l'IEC 61000-6-4 et de l’IEC 61000-6-8, les appareils qui satisfont aux exigences du présent document satisfont également à celles de l'IEC 61000-6-4 et de l’IEC 61000-6-8.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 6-3: Generic standards –
Emission standard for equipment in residential 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 61000-6-3 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 its Amendment

1:2010. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) alternative method for measuring conducted emissions on DC ports;

b) limits and requirements applicable only to equipment intended to be used in residential

locations;

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 6-3: Generic standards –
Emission standard for equipment in residential environments
1 Scope

This generic EMC emission standard is applicable only if no relevant dedicated product or

product family EMC emission standard has been published.

This part of IEC 61000 for emission requirements applies to electrical and electronic equipment

intended for use at residential (see 3.1.14) locations. This part of IEC 61000 also applies to

electrical and electronic equipment intended for use at other locations that do not fall within the

scope of IEC 61000-6-8 or IEC 61000-6-4.

The intention is that all equipment used in the residential, commercial and light-industrial

environments are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the

requirements in IEC 61000-6-3 apply.

The conducted and radiated emission requirements in the frequency range up to 400 GHz are

considered essential and have been selected to provide an adequate level of protection of radio

reception in the defined electromagnetic environment. Not all disturbance phenomena have

been included for testing purposes but only those considered relevant for the equipment

intended to operate within the locations included within this document.

The emission requirements in this document are not intended to be applicable to the intentional

transmissions and their harmonics from a radio transmitter as defined by the ITU.

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 can be employed.

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

NOTE 4 As the requirements in this document are more stringent or equivalent to those requirements in IEC 61000-

6-4 and IEC 61000-6-8, equipment fulfilling the requirements of this document comply with the requirements of

IEC 61000-6-4 and IEC 61000-6-8.
