INTERPRETATION SHEET
This interpretation sheet has been prepared by CISPR subcommittee H: Limits for the
protection of radio services, of IEC technical committee CISPR: International special
committee on radio interference.
The text of this interpretation sheet is based on the following documents:
FDIS Report on voting
CISPR/H/217/FDIS CISPR/H/222/RVD

Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.
___________
Interpretation
The requirement in Clause 8 “Measurement uncertainty” of IEC 61000-6-3 Amend. 1 ed. 2.0:
8 Measurement uncertainty
The measurement instrumentation uncertainty shall be determined according to CISPR
16-4-2, where applicable.
NOTE For a given test method, the actual value of U has only to be recorded in the test report if the
lab
value is greater than U .
CISPR
shall be interpreted as follows:
The measurement instrumentation uncertainty shall be calculated and compared with the
budgets defined in CISPR 16-4-2. For each applicable test method, whose instrumentation
uncertainty budgets are higher than those defined in CISPR 16-4-2, compliance with the limits
has to be determined according to CISPR 16-4-2 methodology. This requirement is only
applicable for tests where an uncertainty budget is defined in CISPR 16-4-2.
The additional note was further clarification that there is no need to state in the test report the
laboratory uncertainty budget U if this is less than or equal to the U defined in CISPR
lab CISPR
16-4-2. However, it has to be mentioned in the test report that the instrumentation
measurement uncertainty is determined according to CISPR16-4-2.

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.

This consolidated version of IEC 61000-6-3 consists of the second edition (2006)
[documents CISPR/H/121/FDIS and CISPR/H/124/RVD] and its amendment 1 (2010)
[documents CISPR/H/206/FDIS and CISPR/H/210/RVD]. It bears the edition number 2.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.

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.

61000-6-3 © IEC:2006+A1:2010 – 7 –
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.

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.
Where applicable, additional information on EUT configuration can be found in the CISPR 16-2
series and CISPR 22.
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.
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 Tables 1 to 4.
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. The requirements are stated in Tables 1 to 4
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 Tables 1 to 4.
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
Measurement uncertainty
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
n
where
x is the arithmetic mean of the measured value of n items in the sample
n
S = (x − x)²
n i
∑
n−1
i=1
x is the value of the individual item
n
L is the appropriate limit
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).

9 Measurement uncertainty Application of limits in tests for conformity
of equipment in series production
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.
9.1 Tests shall be made:
– either on a sample of equipment of the type using the statistical method of evaluation set
out in 9.2,
– or, for simplicity’s sake, on one equipment only.
9.2 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

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).

10 Compliance with this standard
Where this standard gives options for testing particular requirements with a choice of test
methods, compliance can be shown against any of the test methods, using the specified limits
with the restrictions provided in the relevant tables.
In any situation where it is necessary to retest the equipment the test method original chosen
