IEC 61000-6-3:2006

Electromagnetic compatibility (EMC) - Part 6-3: Generic standards - Emission standard for residential, commercial and light-industrial environments

This part of IEC 61000 for EMC emission requirements applies to electrical and electronic apparatus intended for use in residential, commercial and light-industrial environments. 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 apparatus intended to be directly connected to a low-voltage public mains network or connected to a dedicated DC source, which is intended to interface between the apparatus and the low-voltage public mains network. This standard applies also to apparatus which is battery operated or is powered by a non-public, but non-industrial, low-voltage power distribution system if this apparatus is intended to be used in the locations described below. The environments encompassed by this standard are residential, commercial and light-industrial locations, both indoor and outdoor. The following list, although not comprehensive, gives an indication of locations that are included: - residential properties, for example houses, apartments; - retail outlets, for example shops, supermarkets; - business premises, for example offices, banks; - areas of public entertainment, for example cinemas, public bars, dance halls; - outdoor locations, for example petrol stations, car parks, amusement and sports centres; - light-industrial locations, for example workshops, laboratories, service centres. Locations that are characterised by being supplied directly at low voltage from the public mains network are considered to be residential, commercial or light-industrial. 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 residential, commercial and light-industrial locations do not exceed a level which 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 6-3: Normes génériques - Norme sur l'émission pour les environnements résidentiels, commerciaux et de l'industrie légère

La présente partie de la CEI 61000 concernant les exigences d'émissions en matière de compatibilité électromagnétique s'applique aux appareils électriques et électroniques destinés à être utilisés dans des environnements résidentiels, commerciaux et de l'industrie légère. 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. Cette norme s'applique aux appareils destinés à être raccordés directement au réseau public d'alimentation basse tension ou à une source de courant continu spécifique destinée à servir d'interface entre l'appareil et le réseau public d'alimentation basse tension. Cette norme s'applique également aux appareils alimentés par piles ou batteries ou par un système de distribution basse tension non public mais non industriel, lorsque cet appareil est destiné à être utilisé dans les emplacements décrits ci-dessous. Les environnements couverts par cette norme sont les sites résidentiels, les locaux commerciaux et de l'industrie légère, à la fois intérieurs et extérieurs. La liste suivante, bien que non exhaustive, donne une indication sur les sites qui sont couverts: - propriétés résidentielles, par exemple maisons, appartements ; - lieux de vente au détail, par exemple boutiques, supermarchés; - centres d'affaires, par exemple bureaux, banques; - locaux de loisirs recevant du public, par exemple cinémas, bars, dancings; - sites extérieurs, par exemple stations service, parcs de stationnement, centres de loisirs et centres sportifs; - locaux de l'industrie légère, par exemple ateliers, laboratoires, centres de services. Les sites qui sont caractérisés comme étant alimentés directement en basse tension par le réseau public sont considérés comme résidentiels, commerciaux ou pour l'industrie légère. 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 résidentiel, commercial ou de l'industrie légère, 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 61000-6-3 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 1996 as

CISPR/IEC 61000-6-3. 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 dc power ports and

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 6-3: Generic standards –
Emission standard for residential,
commercial and light-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 residential, commercial and light-industrial environments.

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 apparatus intended to be directly connected to a low-voltage public

mains network or connected to a dedicated DC source, which is intended to interface between

the apparatus and the low-voltage public mains network. This standard applies also to

apparatus which is battery operated or is powered by a non-public, but non-industrial, low-

voltage power distribution system if this apparatus is intended to be used in the locations

described below.

The environments encompassed by this standard are residential, commercial and light-

industrial locations, both indoor and outdoor. The following list, although not comprehensive,

gives an indication of locations that are included:
– residential properties, for example houses, apartments;
– retail outlets, for example shops, supermarkets;
– business premises, for example offices, banks;
– areas of public entertainment, for example cinemas, public bars, dance halls;

– outdoor locations, for example petrol stations, car parks, amusement and sports centres;

– light-industrial locations, for example workshops, laboratories, service centres.

Locations that are characterised by being supplied directly at low voltage from the public

mains network are considered to be residential, commercial or light-industrial.

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 residential, commercial and light-industrial locations do

not exceed a level which 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.
---------------------- Page: 8 ----------------------
61000-6-3 © IEC:200661000-6-3  IEC:2006 –– 7 – 13 –
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.

NOTE 3 As the requirements in this standard are more stringent than the requirements in IEC 61000-6-4,

equipment fulfilling the requirements of this standard will also comply with the requirements of IEC 61000-6-4.

NOTE Connection to a remote local battery is not regarded as a DC power network, if such a link comprises only

power supply for a single piece of equipment.
4 Conditions during testing

The equipment under test (EUT) shall be tested in the operating mode producing the largest

emission in the frequency band being investigated, e.g. based on limited pre-tests and

consistent with normal applications. The configuration of the test sample shall be varied to

achieve maximum emission consistent with typical applications and installation practice.

If the apparatus is part of a system, or can be connected to auxiliary apparatus, the apparatus

shall be tested while connected to the minimum representative configuration of auxiliary

apparatus necessary to exercise the ports in a similar manner to that described in CISPR 22.

In cases where a manufacturer's specification requires external filtering and/or shielding

devices or measures that are clearly specified in the user's manual, the measurement

requirements of this standard shall be applied with the specified devices or measures in

place.

The configuration and mode of operation during the measurements shall be precisely noted in

the test report. If the apparatus 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.

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.
5 Product documentation

The purchaser/user shall be informed if special measures have to be taken to achieve

compliance, e.g. the use of shielded or special cables.
---------------------- Page: 11 ----------------------
61000-6-3  IEC:2006 –– 10 – 19 – 61000-6-3 © IEC:2006
6 Applicability

The application of measurements for emission(s) depends on the particular apparatus, its

configuration, its ports, its technology and its operating conditions.

Measurements shall be applied to the relevant ports of the apparatus according to Table 1.

Measurements shall only be carried out where the relevant ports exist.

It may be determined from consideration of the electrical characteristics and usage of a

particular apparatus that some of the measurements are inappropriate and therefore

unnecessary. In such a case it is required that the decision and justification not to measure

shall be recorded in the test report.
7 Emission requirements

The emission requirements for apparatus covered by this standard are given on a port by port

basis.
Measurements shall be conducted in a well-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, which are

referred to in the Table 1.

The contents of the standards referenced in the tables are not repeated here, however

modifications or additional information needed for the practical application of the

measurements are given in this standard.

8 Application of limits in tests for conformity of equipment in series production

8.1 Tests shall be made:

– either on a sample of equipment of the type using the statistical method of evaluation set

out in 8.2,
– or, for simplicity’s sake, on one equipment only.
8.2 Statistically assessed compliance with limits shall be made as follows.

This test shall be performed on a sample of not less than five and not more than 12 items of

the type. If, in exceptional circumstances, five items are not available, a sample of four or

three shall be used. Compliance is judged from the following relationship:
x + kS ≤ L
where
x is the arithmetic mean of the measured value of n items in the sample
S = ()x − x ²
n i
n−1
i=1
x is the value of the individual item
L is the appropriate limit
---------------------- Page: 12 ----------------------
61000-6-3 © IEC:200661000-6-3  IEC:2006 –– 11 – 21 –

k is the factor derived from tables of the non-central t-distribution which assures with 80 %

confidence that 80 % of the type is below the limit; the value of k depends on the sample

size n and is stated below.

The quantities x , x , S and L are expressed logarithmically: dB(µV), dB(µV/m) or dB(pW).

n n
n 3 4 5 6 7 8 9 10 11 12
k 2,04 1,69 1,52 1,42 1,35 1,30 1,27 1,24 1,21 1,20
9 Measurement uncertainty

The results of measurements of emissions from ITE shall reference the measurement

instrumentation uncertainty considerations contained in CISPR 16-4-2.

Determining compliance with the limits in this standard shall be based on the results of the

compliance measurement, not taking into account measurement instrumentation uncertainty.

However measurement uncertainty of the measurement instrumentation and its associated

connections between the various instruments in the measurement chain shall be calculated

and both the measurement results and the calculated uncertainty shall appear in the test

report.

disturbance.

NOTE 1 If the internal emission source(s) is operating at a frequency below 9 kHz then measurements need only to be performed up to 230 MHz.

NOTE 2 Applicable to apparatus covered within the scope of IEC 61000-3-2, IEC 61000-3-3 or IEC 61000-3-12.

NOTE 3 If the apparatus is covered by the scope of IEC 61000-3-11, this may be used instead of IEC 61000-3-3.

NOTE 4 At transitional frequencies the lower limit applies.

NOTE 5 The limits decrease linearly with the logarithm of the frequency in the range 0,15 MHz to 0,5 MHz.

NOTE 6 The current and voltage disturbance limits are derived for use with an impedance stabilization network (ISN) which presents a common mode (asymmetric mode) impedance of

150 Ω to the telecommunication port under test (conversion factor is 20 log 150 / l = 44 dB).
