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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

1 Scope
1.1 This standard applies to the conduction and the radiation of radio-frequency disturbances
from appliances whose main functions are performed by motors and switching or regulating
devices, unless the r.f. energy is intentionally generated or intended for illumination.
It includes such equipment as: household electrical appliances, electric tools, regulating
controls using semiconductor devices, motor-driven electro-medical apparatus, electric/
electronic toys, automatic dispensing machines as well as cine or slide projectors.
Also included in the scope of this standard are:
– separate parts of the above mentioned equipment such as motors, switching devices e.g.
(power or protective) relays, however no emission requirements apply unless formulated in
this standard.
Excluded from the scope of this standard are:
– apparatus for which all emission requirements in the radio frequency range are explicitly
formulated in other IEC or CISPR standards;
NOTE 1 Examples are:
− luminaires, including portable luminaires for children, discharge lamps and other lighting devices:
CISPR 15;
− audio and video equipment and electronic music instruments, other than toys: CISPR 13 and CISPR 20 (see
also 7.3.5.4.2);
− mains communication devices, as well as baby surveillance systems: IEC 61000-3-8;
− equipment for generation and use of radio frequency energy for heating and therapeutic purposes:
CISPR 11;
− microwave ovens: CISPR 11 (but be aware of 1.3 on multifunction equipment);
− information technology equipment, e.g. home computers, personal computers, electronic copying machines:
CISPR 22;
− electronic equipment to be used on motor vehicles: CISPR 12;
− radio controls, walkie-talkies and other types of radio-transmitters, also when used with toys.
– regulating controls and equipment with regulating controls incorporating semiconductor
devices with a rated input current of more than 25 A per phase;
– stand-alone power supplies.
NOTE 2 Toys powered by the supply system of a motor-powered vehicle, ship or aircraft are not covered by this
standard.

1.2 The frequency range covered is 9 kHz to 400 GHz.
1.3 Multifunction equipment which is subjected simultaneously to different clauses of this
standard and/or other standards shall meet the provisions of each clause/standard with the
relevant functions in operation; details are given in 7.2.1.
1.4 The limits in this standard have been determined on a probabilistic basis, to keep the
suppression of disturbances economically feasible while still achieving an adequate radio
protection. In exceptional cases radio frequency interference may occur, in spite of
compliance with the limits. In such a case, additional provisions may be required.
1.5 The effects of electromagnetic phenomena relating to the safety of apparatus are
excluded from the scope of this standard.

4 Limits of disturbance
Radio disturbance measurements below 148,5 kHz and above 300 MHz need not to be carried
out, unless otherwise specified in this standard for specific appliances.
4.1 Continuous disturbance
Commutator motors, as well as other devices incorporated in household appliances, electric
tools and similar electrical apparatus may cause continuous disturbance.
Continuous disturbance may be either broadband, caused by switching devices such as
mechanical switches, commutators and semiconductor regulators, or may be narrowband,
caused by electronic control devices such as microprocessors.
NOTE Instead of the concept of "broadband" and "narrowband" disturbances, in this standard a distinction is
made between two related kinds of disturbance, defined by the type of the applied detector. For this purpose limits
have been defined with respect to the measurement with the quasi-peak detector and with the average detector
(see 5.1.1 and 6.1.1).
4.1.1 Frequency range 148,5 kHz to 30 MHz (terminal voltages)
NOTE The World Administrative Radiocommunications Conference (WARC) has in 1979 reduced the lower
frequency limit in Region 1 to 148,5 kHz; for applications falling in the scope of this standard, tests at 150 kHz are
considered adequate, since 148,5 kHz falls within the receiver bandwidth.
The limits of the terminal disturbance voltages are given in Table 1. Terminal voltages are
measured, in accordance with Clause 5, on each terminal with respect to ground.
Terminals are defined as conductive parts, suitable for re-usable electrical connection to
external circuits.
4.1.1.1 The limits in columns 2 and 3 shall be met on the phase(s) and the neutral of the
mains terminals of all appliances except those of electric tools.
4.1.1.2 On additional terminals of appliances as well as on load and additional terminals of
regulating controls incorporating semiconductor devices the relaxed limits given for "additional
terminals" in columns 4 and 5 apply.
Terminals which may be used as either mains terminals or load/additional terminals are
subject to the limits for mains terminals.
No terminal voltage limits apply for leads, which are not easily extensible by the user
(permanently connected, or provided with a specific connector), which are shorter than 2 m,
and which connect the equipment with an auxiliary apparatus or device, (e.g. semiconductor
speed controls, power plugs with AC-DC converters).

CISPR 14-1  IEC:2005 – 25 –
No terminal voltage limits apply to leads integrated in the suction hose of vacuum cleaners,
even if the length exceeds 2 m.
NOTE For the measurement at the load terminals and additional terminals of regulating controls incorporating
semiconductor devices see 5.2.4, for additional terminals of other appliances see 5.2.3.
4.1.1.3 For the mains terminals of electric tools the particular limits given in columns 6 to 11
apply according to the rated power of the motor, the power of any heating device is to be
excluded (for instance heating power in a blower for plastic welding). For the load terminals
and additional terminals of electric tools, columns 4 and 5 apply without further relaxation.

* If the limit for the measurement with the average detector is met when using a receiver with a quasi-peak
detector, the equipment under test shall be deemed to meet both limits and the measurement using the receiver
with an average detector need not be carried out.

NOTE The limits for the measurement with the average detector are tentative and may be modified after a period
of experience.
4.1.1.4 Limits for electric fence energizers apply to
a) the fence terminals on all energizers (columns 4 and 5 of Table 1);
b) the mains terminals on energizers designed for connection to the mains (columns 2 and 3
of Table 1);
CISPR 14-1  IEC:2005 – 27 –
c) the battery terminals on energizers designed for operation from a battery (columns 4 and
5 of Table 1).
However, no limits apply to the battery terminals of energizers with built-in batteries which
cannot be connected to the mains supply, or energizers with external batteries if the
connecting lead between the energizer and the battery is shorter than 2 m and is not
applicable of being easily extended by the user without special tools.
Type D energizers, according to IEC 60335-2-76, are measured as battery operated
energizers with connecting leads between the energizer and the battery greater than 2 m in
length.
NOTE In practice, the fence wire can also act as an active source of disturbances, due to the high-voltage
discharges, in particular to radio and telecommunication networks. Manufacturers of electric fence energizers
should instruct the users to eliminate discharge points such as touching vegetation or a broken fence wire.
4.1.1.5 For battery operated appliances (with built-in batteries, as well as with external
batteries) which can be connected to the mains the limits of columns 2 and 3 of Table 1 apply
to the mains terminals.
No radio disturbance limits apply to appliances with built-in batteries, which cannot be
connected to the mains supply.
No radio disturbance limits apply to appliances with external batteries, if the connecting lead
between appliance and battery is shorter than 2 m. If the connecting lead is longer than 2 m
or easily extendable by the user without special tools, then the limits of columns 4 and 5 of
Table 1 apply to these leads.
4.1.2 Frequency range 30 MHz to 300 MHz (disturbance power)
The limits of the disturbance power are given in Table 2.
Disturbance power is measured in accordance with Clause 6, at all terminals.

NOTE The limits for the measurement with the average detector are tentative and may be modified after a period
of experience.
4.1.2.1 The limits in columns 2 and 3 of Table 2 shall be met by all appliances except those
mentioned in 4.1.2.2, second paragraph, to 4.1.2.4.

CISPR 14-1  IEC:2005 – 29 –
4.1.2.2 For battery operated appliances (with built-in batteries as well as with external
batteries) which can be connected to the mains the limits of columns 2 and 3 of Table 2 apply,
together with 4.1.2.3 and 4.1.2.4.
For battery operated appliances (with built-in batteries) which cannot be connected to the
mains, no disturbance power limits apply.
4.1.2.3 For electric tools the particular limits given in columns 4 to 9 of Table 2 apply
according to the rated power of the motor, the power of any heating device is to be excluded
(for instance heating power in a blower for plastic welding).
4.1.2.4 Regulating controls which incorporate semiconductor devices, electric fence
energizers, rectifiers, battery chargers and converters which do not contain any internal
frequency or clock generator operating at frequency higher than 9 kHz are not subject to the
disturbance power requirements in the frequency range 30 MHz to 300 MHz.
4.1.3 Frequency range 30 MHz to 1 000 MHz (radiated disturbances)
The limits of radiated disturbances are given in Table 3.
Radiated disturbances are measured in accordance with CISPR 22.

The lower limit is applicable at the transition frequency.

Radiated disturbance requirements in this standard are restricted to toys. Measurements may
be made at closer distance, down to 3 m. An inverse proportionality factor of 20 dB per
decade shall be used to normalize the measured data to the specified distance for
determining compliance.
In case of dispute, the measurements at distances stated in the test report are verified.
4.2 Discontinuous disturbance
Switching operations in thermostatically controlled appliances, automatic programme
controlled machines and other electrically controlled or operated appliances generate
discontinuous disturbance. The subjective effect of discontinuous disturbance varies with
repetition rate and amplitude in audio and video presentation. Therefore distinction is made
between various kinds of discontinuous disturbance.
The discontinuous disturbance is only measured with a measuring receiver including a quasi-
peak detector as mentioned in 5.1.1 and specified in Clause 4 of CISPR 16-1-1.
See Annex C for guidance.
CISPR 14-1  IEC:2005 – 31 –
4.2.1 The limits for discontinuous disturbance depend mainly on the character of the
disturbance and on the click rate N as given in detail in 4.2.2 and 4.2.3.
No discontinuous disturbance limits apply in the frequency range 30 MHz to 300 MHz.
NOTE The level of disturbances below 30 MHz is interpreted as an indication for the level above 30 MHz.
4.2.2 Frequency range 148,5 kHz to 30 MHz (terminal voltages)
4.2.2.1 The limits of Table 1 apply also to discontinuous disturbances from all equipment
which produce:
a) disturbances other than clicks, or
b) clicks with a click rate N equal to or greater than 30.
Appliances as described in 4.2.3 are exempted.
NOTE Examples of discontinuous disturbances for which the limits for continuous disturbance apply are shown in
Figures 4a and 4b.
4.2.2.2 For discontinuous disturbance, the click limit L is attained by increasing the relevant
q
limit L (as given in 4.1.1) with:
44 dB for N < 0,2, or
20 lg (30/N) dB for 0,2 ≤ N < 30
NOTE Examples of discontinuous disturbances which are classified as clicks are shown in Figures 3a, 3b and 3c.
See also Annex A, Table A.1 and Table A.2.
4.2.2.3 The click limit L applies for click rates N determined under operating conditions and
q
interpretation of results as specified in Clause 7.
4.2.3 Exceptions from the click definition
Under certain conditions some kinds of discontinuous disturbances are exempted from the
definition of a click (see 3.2).
This subclause contains these exceptions which are applicable in combination with
subclauses 4.2.1 and 4.2.2 to all kinds of appliances. In Figure 9, a flow diagram shows how
to take these conditions into account in the verification procedure.
Product specific relaxations are contained in Annex A, which contains also Table A.2, a list of
appliances for which the switching operations are counted, to derive the click rate N.
4.2.3.1 Individual switching operations
The disturbance from individual switching operations, caused directly or indirectly, manually
or by similar activities on a switch or a control which is included in an appliance or otherwise
to be used for:
a) the purpose of mains connection or disconnection only;
b) the purpose of programme selection only;
