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;
c) more stringent limits for DC power ports.

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.

4 Classification of equipment
For equipment within the scope of this document the requirements of Table 3 to Table 6 apply.
These requirements are intended to offer adequate protection to radio services within the
residential environment.
NOTE Examples of the emission classification of equipment and mapping to the immunity standards is given in
Annex A.
5 Measurements and conditions during testing
Measurements shall be conducted in a defined and reproducible manner.
The measurements may be performed in any order.
The description of the measurement, the measurement instrumentation, the measurement
methods and the measurement set-up to be used are given in the standards, referred to in
Table 3 to Table 6. The contents of these standards are not repeated here, however
modifications or additional information needed for the practical application of the measurements
are given in this document.
All aspects of testing the EUT shall be defined and documented in a test plan prior to testing.
This requirement includes, but is not limited to, the following details: EUT configuration, EUT
modes of operation, EUT highest internal frequency (see Table 2), EUT arrangement (see Table
1). These details as a minimum shall be included in the test report.
The EUT shall be tested in the operating mode producing the largest emission in the frequency
band being assessed, consistent with intended use. The configuration of the test sample shall
be varied to achieve maximum emission consistent with typical use and installation practice.
NOTE Pre-testing could be used to reduce test time.
– 12 – IEC 61000-6-3:2020 © IEC 2020
If the EUT is part of a system, or can be connected to associated equipment, the EUT shall be
tested while connected to the minimum representative configuration of associated apparatus
necessary to exercise the ports in a similar manner to that described in CISPR 32. If the EUT
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.
In cases where the equipment instructions requires external filtering, shielding devices or
measures, these measures shall be applied during the measurements.
The EUT shall be arranged in accordance with the requirements of Table 1.
Table 1 – Test arrangements of EUT
Intended operational Test arrangement Remarks
arrangement(s) of EUT
Table-top only Table-top
Floor-standing only Floor-standing 1
See table clause 3.3 for testing in a FAR
Can be floor-standing or table-top Table-top
Rack mounted In a rack or table-top
Other, for example wall mounted, Table-top With normal orientation
ceiling mounted, handheld, body
If the equipment is designed to be mounted on
worn
a ceiling, the downward-facing portion of the
EUT may be oriented facing upward.
If a physical hazard would be caused by testing the device on a table-top, then it may be tested as floor standing
and the test report shall document the decision and justification.
The measurements 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. The relevant conditions
shall be recorded in the test report.
Where applicable, additional information on EUT configuration can be found in the CISPR 16-2-
1, CISPR 16-2-3, CISPR 14-1 or CISPR 32 as referenced in Table 3 to Table 6.
6 Documentation for the user
The equipment instructions for use shall include the following:
• a statement that the equipment satisfies the requirements for use within a residential
location,
• any special measures that have to be taken to achieve compliance.
EXAMPLE The instructions for use could require the use of shielded or special cables.
7 Applicability
The application of measurements for emission(s) depends on the particular equipment, its
configuration, its ports, its technology and its operating conditions.
___________
In this document, table clauses are referenced using an x.y format, where x denotes the table and y denotes
the referenced clause by row within the table. For example table clause 3.1 is Table 3, clause (row) 1.
CISPR 61000-6-3:2020 © IEC 2020 – 13 –
Measurements shall be applied to the relevant ports of the equipment specified in Table 3 to
Table 6. Measurements shall only be carried out where the relevant ports exist.
All tests defined in Table 3 to Table 6 shall be considered by the test plan, however, where it
has been determined in the test plan, that one or more of the tests are not applicable, the
decision and justification not to perform such tests shall be recorded in the test report. See
examples.
EXAMPLE When considering a test plan for an EUT, which is always powered through a UPS, then conducted tests
on the low voltage AC mains port are not necessary.
8 Requirements
The requirements are given in Table 3 to Table 6.
9 Measurement uncertainty
Where guidance for the calculation of the instrumentation uncertainty of a measurement is
specified in CISPR 16-4-2, this shall be followed. For these measurements the determination
of compliance with the limits in this document shall take into consideration the measurement
instrumentation uncertainty in accordance with CISPR 16-4-2. Calculations to determine the
measurement result and any adjustment of the test result required when the test laboratory
uncertainty is larger than the value for U given in CISPR 16-4-2 shall be included in the test
cispr
report.
10 Compliance with this document
Where this document gives options for testing particular requirements with a choice of test
methods, compliance can be shown against any of the relevant test methods, using the
specified limits within the restrictions provided in the relevant table clauses. For example, floor
standing equipment shall be assessed against table clause 3.1, considering table clause 3.2 is
limited to small equipment and table clause 3.3 is limited to table top equipment.
In any situation where it is necessary to retest the equipment, the test method originally chosen
shall be used in order to ensure consistency of the results.
The test report shall contain sufficient details to facilitate reproducibility of the measurements.
Equipment which fulfills the requirements across the frequency ranges specified in Table 3 to
Table 6, in this document is deemed to fulfill the requirements in the entire frequency range up
to 400 GHz.
Measurements do not need to be performed at frequencies where no limits are specified.
11 Emission test details
The following shall be taken into account during the application of the measurements defined
in Table 3 to Table 6.
• At transitional frequencies, the lower limit applies.
• Where the limit value varies over a given frequency range, it changes linearly with respect
to the logarithm of the frequency.
• The test site shall be validated for the measurement distance chosen.
– 14 – IEC 61000-6-3:2020 © IEC 2020
• Where the table clause defines more than one detector, then the measurements shall be
performed using both types of detector. Results obtained using a peak detector may be used
instead of the defined detectors.
• Where a different measurement distance is chosen, other than the reference distance
defined in the limit column of Table 3, the limits shall be offset based upon the following
formula:
new limit = defined limit – 20 log (measurement distance/reference distance)
The unit of metres shall be used for distance and dB(µV/m) for the limits.
With regard to each table clause, the measurements shall be performed at only one distance.
• For radiated emissions measurements, Table 2 shows the highest frequency up to which
measurements shall be performed based upon the value of F .

For all other measurements, the entire frequency range shall be measured.
• For emission measurements above 1 GHz, the peak detector limits shall not be applied to
disturbances produced by arcs or sparks that are high voltage breakdown events. Such
disturbances arise when devices contain or control mechanical switches that control current
in inductors, or when devices contain or control subsystems that create static electricity
(such as paper handling devices). The average limits apply to disturbances from arcs or
sparks, and both peak and average limits will apply to all other disturbances from such
devices.
