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.

4 Classification of apparatus
4.1 The equipment covered by this document is subdivided into categories. For each
category, specific requirements are formulated.
4.2 Category I: equipment containing no electronic control circuitry.
EXAMPLES Appliances, tools and toys that contain no electronic control circuits and only electromechanical
components such as switches, thermostats, brush motors, induction motors, heating elements, lighting toys
containing only batteries and LED.
Electrical circuits consisting of passive components (such as radio interference suppression
capacitors or inductors, mains transformers, mains frequency rectifiers) are not considered to
be electronic control circuitry.
4.3 Category II: mains operated equipment containing electronic control circuitry with no
clock frequency higher than 15 MHz.
4.4 Category III: battery operated equipment not included in Category I.
EXAMPLES Appliances, tools and toys powered by batteries and that include a microprocessor to provide a
selection of functions.
NOTE The assignment to Category III is independent of the clock frequency.
This category also includes equipment provided with rechargeable batteries, which can be
charged, directly or indirectly, from the mains. Accordingly, this equipment shall also be
subjected to the test requirements for mains operated equipment but only when testing the
charging function.
If the equipment can operate its intended functions when connected, directly or indirectly to the
mains, then it is not battery operated. Accordingly, it shall be classified as Category II, Category
IV or Category V, as applicable, and subjected to the corresponding test requirements when in
mains operation.
4.5 Category IV: mains operated equipment containing electronic control circuitry with a
highest clock frequency greater than 15 MHz but lower than or equal to 200 MHz.
4.6 Category V: mains operated equipment containing electronic control circuitry with a
highest clock frequency greater than 200 MHz.

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 CISPR 14-2 has been prepared by CISPR subcommittee F: Interference
relating to household appliances tools, lighting equipment and similar apparatus.
This third edition cancels and replaces the second edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) extension of the frequency range for radiated immunity above 1 GHz;

4 Classification of apparatus
4.1 The equipment covered by this document is subdivided into categories. For each
category, specific requirements are formulated.
4.2 Category I: equipment containing no electronic control circuitry.
EXAMPLES Appliances, tools and toys that contain no electronic control circuits and only electromechanical
components such as switches, thermostats, brush motors, induction motors, heating elements, lighting toys
containing only batteries and LED.
Electrical circuits consisting of passive components (such as radio interference suppression
capacitors or inductors, mains transformers, mains frequency rectifiers) are not considered to
be electronic control circuitry.
4.3 Category II: mains operated equipment containing electronic control circuitry with no
clock frequency higher than 15 MHz.
4.4 Category III: battery operated equipment not included in Category I.
EXAMPLES Appliances, tools and toys powered by batteries and that include a microprocessor to provide a
selection of functions.
NOTE The assignment to Category III is independent of the clock frequency.
This category also includes equipment provided with rechargeable batteries, which can be
charged, directly or indirectly, from the mains. Accordingly, this equipment shall also be
subjected to the test requirements for mains operated equipment but only when testing the
charging function.
If the equipment can operate its intended functions when connected, directly or indirectly to the
mains, then it is not battery operated. Accordingly, it shall be classified as Category II, Category
IV or Category V, as applicable, and subjected to the corresponding test requirements when in
mains operation.
4.5 Category IV: mains operated equipment containing electronic control circuitry with a
highest clock frequency greater than 15 MHz but lower than or equal to 200 MHz.
4.6 Category V: mains operated equipment containing electronic control circuitry with a
highest clock frequency greater than 200 MHz.
