Electromagnetic compatibility - Requirements for household appliances, electric tools and similar apparatus - Part 1: Emission
This part of CISPR 14 specifies the requirements that apply to the emission of radio-frequency
disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools and similar
apparatus as defined below, whether powered by AC or DC (including a battery).
This document is applicable to the following equipment:
• household appliances or similar equipment;
NOTE 1 Examples are equipment used:
– for typical housekeeping functions in the household environment, which includes the dwelling and its
associated buildings, the garden, etc.;
– for typical housekeeping functions in shops, offices, commercial and other similar working environments;
– on farms;
– by clients in hotels and other residential type environments;
– for induction cooking or air-conditioning, either in residential or commercial environments.
• electric tools;
NOTE 2 Examples of electric tools include electric motor-operated or electromagnetically driven hand-held tools,
transportable tools, lawn and garden machinery.
• similar apparatus.
NOTE 3 Examples are:
– external power controllers using semiconductor devices;
– motor-driven electro-medical equipment;
– electric/electronic toys;
– personal care and beauty care appliances;
– automatic goods-dispensing machines;
– entertainment machines;
– cine or slide projectors;
– battery chargers and external power supplies for use with products under the scope of this document;
– electric fence energisers.
Also included in the scope of this document are separate parts of the above mentioned
equipment such as motors and switching devices (e.g. power or protective relays). However,
no emission requirements apply to such separate parts, unless otherwise stated in this
document.
Products which incorporate radio transmit/receive functions are included in the scope of this
document.
Equipment under the scope of this document making use of IPT is also in the scope.

CISPR 14-1:2020 © IEC 2020 – 11 –
Excluded from the scope of this document are:
– equipment for which all emission requirements in the radio-frequency range are explicitly
formulated in other CISPR standards;
NOTE 4 Examples are:
− luminaires, including portable luminaires for children, discharge lamps and other lighting devices under the
scope of CISPR 15;
− information technology equipment, e.g. home computers, personal computers, electronic copying machines
under the scope of CISPR 32;
− audio/video equipment and electronic music instruments other than toys under the scope of CISPR 32;
− mains communication devices, as well as baby surveillance systems;
− equipment which is under the scope of CISPR 11 (e.g. microwave ovens) but be aware of 6.5 on
multifunction equipment (e.g. for another function requiring click measurements)
− radio controls, walkie-talkies and other types of radio-transmitters;
− arc welding equipment.
– equipment intended to be used only on a vehicle, ship or aircraft;
– equipment used only in industrial environment
– the effects of electromagnetic phenomena relating to the safety of the equipment.
Multifunction equipment may be required to comply with clauses in this and other standards.
The details are given in 6.5.
The emission requirements in this document are not intended to be applicable to the intentional
transmissions from a radio transmitter as defined by the ITU including their spurious emissions.

Part 1: Emission
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 apparatus,
of IEC technical committee CISPR.
This seventh edition cancels and replaces the sixth edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant changes with respect to the previous edition:
– extension of the frequency range for radiated measurements above 1 GHz;
– revision of general test conditions and addition of new specific test conditions (e.g. for
robotic equipment);
– introduction of additional requirements for equipment making use of inductive power transfer
technology;
CISPR 14-1:2020 © IEC 2020 – 9 –
– remove from the normative text any compliance requirement based on statistical evaluation;
– revision of clicks analysis, with particular relevance to the determination of the observation
time and the application of the upper quartile method for different types of click analysers.
The text of this document is based on the following documents:
