INTERPRETATION SHEET 1
This interpretation sheet has been prepared by subcommittee CISPR F: Interference relating
to household appliances tools, lighting equipment and similar apparatus, 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

___________
Interpretation Sheet 1 to CISPR 14-1: Interpretation of subclause 5.4.2.4 of CISPR 14-
1:2016 on the upper quartile method for the evaluation of clicks
Introduction
The evaluation of clicks has to be performed at four frequencies while the determination of the
click rate N is made only at two frequencies. The application of the upper quartile method at
the frequencies 150 kHz and 500 kHz is clear, while the situation is unclear for the
frequencies 1,4 MHz and 30 MHz. This interpretation sheet is intended to clarify this matter.
The click measurement procedure is under revision in CISPR/F WG1 and will be updated in
the next amendment to CISPR 14-1:2016.
Question
How should the upper quartile method be applied at the frequencies 1,4 MHz and 30 MHz?
Interpretation
Each of the following two interpretations is valid.
ICS 33.100.10
IEC 2017
Interpretation 1:
The number of clicks at 1,4 MHz and the number of clicks at 30 MHz which exceed the limit,
L, for continuous disturbances during the observation time, T, are measured. The number of
clicks at 1,4 MHz and the number of clicks at 30 MHz exceeding L are allowed to be one
q
quarter of the number of clicks counted at each respective frequency.
Interpretation 2:
The number of clicks at 1,4 MHz and the number of clicks at 30 MHz which exceed the limit,
L, for continuous disturbances during the observation time, T, are not measured but are
assumed to be equal to the number of clicks counted at 500 kHz during the observation time
T. The number of clicks at 1,4 MHz and the number of clicks at 30 MHz exceeding L are
q
allowed to be one quarter of the number of clicks counted at 500 kHz.
In any situation where it is necessary to verify the original measurement, the assessment
method (interpretation 1 or 2) originally chosen shall be used in order to ensure consistency
of the results.

Interpretation Sheet 2 to CISPR 14-1: Interpretation of subclause A.4.11 of CISPR 14-
1:2016 on the assessment of irons with steam generator
Introduction
Subclause A.4.11 of CISPR 14-1:2016 defines the testing conditions for irons (dry or steam),
but there are no instructions regarding the steam production.
Question
How to set the steam function of irons during CISPR 14-1 emission tests?
ICS 33.100.10
IEC 2017
Interpretation
When measuring disturbances from irons, if the iron has a continuous steam function, it shall
be operated in this mode only and use a sufficient amount of water to facilitate continuous
steaming for the duration of the test.

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.
The International Standard CISPR 14-1 has been prepared by subcommittee CISPR/F:
Interference related to household appliances, tools, lighting equipment and similar appliances,
of IEC technical committee CISPR.
This sixth edition cancels and replaces the fifth edition published in 2005, Amendment 1:2008
and Amendment 2:2011. This edition constitutes a technical revision.
This edition includes the following significant changes with respect to the previous edition:
– full editorial review of the standard, rearranging the structure of several clauses;
– improvements to the operating conditions for testing induction cooking appliances and
incorporation of the limits for these appliances in the body of the standard;
– 8 – CISPR 14-1:2016 © IEC 2016
– moving all specific operating conditions to Annex A;
– improvement of definitions;
– addition of general and specific test setups (e.g. vacuum cleaners and robotic cleaners)
for radiated emission;
– provision for the current probe test method for conducted disturbance measurements on
ports other than the AC mains port in alternative to the voltage probe method;
– clarifications about click analysis (e.g. measurements under the presence of continuous
disturbances). Further clarification is being developed for future inclusion;
– clarification about the use of the artificial hand;
– introduction of testing on wired network ports of household equipment (equivalent to
CISPR 32 requirements);
– clarification in the scope regarding emissions from radio transmitters (copied verbatim
from CISPR 32);
– clarification about the measurement of equipment with built-in luminaries.
The text of this standard is based on the following documents:
