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.

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

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 .

x x
Where the highest internal frequency is not known, tests shall be performed up to
6 GHz.
NOTE F is defined in 3.1.9.
x
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.
• For radiated emission measurements using a FSOATS, OATS, FAR or SAC, the
measurement distance is the shortest horizontal distance between the vertical projections
of the calibration point of the receiving antenna and the boundary of the EUT, when typically
arranged and rotated through 360°.
For frequencies below 1 GHz, a maximum of 1,6 m of cabling shall be considered as part of
the EUT.
The boundary of the EUT is the smallest imaginary circular periphery around the most
compact arrangement of the EUT, using typical spacing, see 7.3.1 in CISPR 16-2-3:2016.
Antennas shall be calibrated in free space conditions using facilities defined in
CISPR 16-1-5:2014 and CISPR 16-1-5:2014/AMD1:2016 whilst using the procedures
defined in CISPR 16-1-6:2014 and CISPR 16-1-6:2014/AMD1:2017.
• Where this document specifies the use of an average detector, the linear average detector
defined in Clause 6 of CISPR 16-1-1:2019 shall be used.
• With regard to conducted emissions on power lines, care shall be taken to ensure emissions
below 150 kHz do not impact the measurements. This is typically achieved using a high
pass filter and an attenuator.
