Electromagnetic compatibility - Requirements for household appliances, electric tools and similar apparatus - Part 1: Emission

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. The frequency range covered is 9 kHz to 400 GHz. 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. 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. The effects of electromagnetic phenomena relating to the safety of apparatus are excluded from the scope of this standard. The contents of the corrigendum of January 2009 have been included in this copy.

Compatibilité électromagnétique - Exigences pour les appareils électrodomestiques, outillages électriques et appareils analogues - Partie 1: Emission

La présente norme s'applique aux perturbations radioélectriques conduites et rayonnées, produites par des appareils dont les fonctions principales sont assurées par des moteurs et par des dispositifs de commutation ou des dispositifs de régulation, sauf si l'énergie RF est produite volontairement, ou destiné à l'éclairage. Elle concerne des appareils tels que: les appareils électrodomestiques, les outils électriques, les dispositifs de commande et de régulation comportant des dispositifs à semiconducteurs, les appareils électromédicaux à moteur, les jouets électriques/électroniques, les distributeurs automatiques ainsi que les projecteurs de cinéma ou de diapositives. Sont également inclus dans le domaine d'application de la présente norme: - les éléments séparés des matériels mentionnés ci-dessus comme, par exemple des moteurs, des dispositifs de commutation, des relais (d'alimentation ou de protection); toutefois, à moins que cela ne soit spécifié dans cette norme, aucune exigence d'émission ne leur est applicable. La gamme des fréquences couvertes est comprise entre 9 kHz et 400 GHz. Un matériel à fonctions multiples, couvert simultanément par différents articles de la présente norme et/ou par d'autres normes, doit satisfaire aux exigences de chaque article et de chaque norme relatives à la fonction correspondante, lorsque celle-ci est activée; pour plus de détails, se reporter à 7.2.1. Les limites spécifiées dans la présente norme ont été déterminées sur une base probabiliste, afin de maintenir la suppression des perturbations dans des limites raisonnables du point de vue économique, tout en assurant une protection adéquate contre les perturbations radioélectriques. Dans certains cas exceptionnels, il est possible qu'un brouillage radioélectrique se produise, malgré la conformité aux limites spécifiées. Dans de tels cas, il est possible que des dispositions supplémentaires soient nécessaires. Les effets des phénomènes électromagnétiques sur la sécurité des appareils sont exclus du domaine d'application de la présente norme. Le contenu du corrigendum de janvier 2009 a été pris en considération dans cet exemplaire.

Overview

CISPR 14‑1:2005 (IEC) is an international EMC standard that specifies emission requirements for household appliances, electric tools and similar apparatus whose primary functions are performed by motors, switching or regulating devices. It covers the conduction and radiation of radio‑frequency (r.f.) disturbances (9 kHz to 400 GHz) and defines limits, measurement methods and operating conditions to assess conducted and radiated emissions from items such as domestic appliances, electric tools, motor‑driven electro‑medical apparatus, electronic toys, automatic dispensing machines and similar equipment.

The standard adopts a probabilistic approach to set economically feasible limits that still provide adequate radio‑protection. It also addresses multifunction equipment and gives guidance on interpreting results; safety‑related electromagnetic effects are excluded from its scope.

Key topics and technical requirements

• Scope and exclusions: Applies to motor/switching‑based apparatus; excludes equipment covered by other CISPR/IEC standards (e.g., lighting - CISPR 15, IT equipment - CISPR 22, industrial RF equipment - CISPR 11).
• Frequency range: 9 kHz to 400 GHz (comprehensive coverage for conducted and radiated emissions).
• Types of emissions:
  • Conducted disturbance voltages (148.5 kHz to 30 MHz)
  • Disturbance power measurements (30 MHz to 300 MHz)
  • Radiated emissions (up to 400 GHz; specific guidance for toys up to 1 GHz)
• Measurement methods and arrangements: Specified measuring devices, test setups for mains and auxiliary leads, use of artificial hand and fixtures, and procedures to isolate equipment under test from external disturbances.
• Continuous vs discontinuous disturbances: Special handling and limits for clicks and intermittent switching events, including statistical methods (upper quartile) for compliance assessment.
• Operating conditions and interpretation: Standard operating loads and conditions, rules for multifunction equipment and integrated parts, assessment rules for production units and exceptional interference cases.

Applications - who uses this standard

• Manufacturers and product designers of household appliances, power tools, motorized toys, electro‑medical devices and control gear - to design for EMC and prepare for market entry.
• EMC test laboratories and compliance engineers - for type testing, pre‑compliance checks and certification.
• Regulatory and compliance officers - to interpret emission limits and demonstrate conformity in large‑scale production.
• R&D and quality teams - to set design targets and verify mitigation measures (filters, shielding, PCB layout).

Related standards

Relevant cross‑references include:

• CISPR 15 (lighting)
• CISPR 11 (industrial, scientific and medical equipment)
• CISPR 16 series (measurement apparatus & methods)
• CISPR 20, CISPR 22, CISPR 12 (audio/video, IT, automotive)
• IEC 60335‑2‑76, IEC 60598 series
• IEC 61000 series (where applicable)

CISPR 14‑1 is essential for ensuring EMC compliance of motor‑ and switch‑based consumer and professional equipment and for minimizing radio‑frequency interference in commercial and residential environments.

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.

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)

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;

CISPR 14-1  IEC:2005 – 33 –
c) the control of energy or speed by switching between a limited number of fixed positions;

d) the changing of the manual setting of a continuously adjustable control such as a

variable speed device for water extraction or electronic thermostats, is to be disregarded

for the purpose of testing the appliance for compliance with the limits of radio disturbance

set out in this standard.
Examples of switches included in this subclause are the on/off switches for apparatus

(including foot activated), for instance the switch for an electric typewriter, manual switches

for heat and air flow control in fan heaters and hair dryers, as well as the indirectly operated

switch in a cupboard, wardrobe or refrigerator, and sensor-operated switches, etc. Switches
which usually will be repeatedly operated are not included in this subclause, e.g. for sewing

machines, calculating machines, soldering equipment, etc. (see 7.2.3. and 7.3.2.4.c).

Also the disturbance caused by the operation of any switching device or control which is
included in an appliance for the purpose of mains disconnection for safety only, is to be
disregarded for the purpose of testing the appliance for compliance with the limits of radio
disturbance as described in this standard.
4.2.3.2 Combination of clicks in a time frame less than 600 ms
In programme controlled appliances a combination of clicks in a time frame less than 600 ms
is allowed once per selected programme cycle.
For other appliances such a combination of clicks is allowed once during the minimum
observation time. This is also valid for thermostatically controlled three-phase switches,
causing three disturbances sequentially in each of the three phases and the neutral. The
combination of clicks is considered as one click.
4.2.3.3 Instantaneous switching
Appliances which fulfil the following conditions:
– the click rate is not more than 5,
– none of the caused clicks has a duration longer than 20 ms,
– 90 % of the caused clicks have a duration less than 10 ms,
shall be deemed to comply with the limits, independent of the amplitude of the clicks (see
tables A.1 and A.2). If one of these conditions is not satisfied then the limits in accordance
with 4.2.2 apply.
4.2.3.4 Separation of clicks less than 200 ms

For appliances which have a click rate less than 5, any two disturbances each having a
maximum duration of 200 ms, shall be evaluated as two clicks even when the separation
between the disturbances is less than 200 ms.
In this case, for instance observed with refrigerators, the example shown in Figure 4b, would
be evaluated as two clicks and not as continuous disturbance.

CISPR 14-1  IEC:2005 – 35 –
5 Methods of measurement of terminal disturbance voltages

(148,5 kHz to 30 MHz)
This clause lays down the general requirements for the measurement of disturbance voltage

produced at the terminals of apparatus.

The operating conditions are given in Clause 7 of this standard.

5.1 Measuring devices
The measuring devices given below are to be used:
5.1.1 Measuring receivers
Receivers with quasi-peak detectors shall be in accordance with Clause 4 of CISPR 16-1-1;
receivers with average detectors shall be in accordance with Clause 6 of CISPR 16-1-1.
NOTE Both detectors may be incorporated in a single receiver and measurements carried out either using the
quasi-peak detector or the average detector.
5.1.2 Artificial mains network
The artificial mains V-network is required to provide a defined impedance at high frequencies
between the terminals of the equipment under test and reference ground, and also to isolate
the test circuit from unwanted radio-frequency signals on the supply mains.
The artificial mains V-network 50 Ω/50 µH (or 50 Ω/50 µH + 5 Ω) as defined in Clause 4 of
CISPR 16-1-2 shall be used.
To ensure that, at the frequency of measurement, the impedance of the mains does not
materially affect the impedance of the artificial mains V-network, a suitable radio-frequency
impedance shall be inserted between the artificial mains V-network and the supply mains.
This impedance will also reduce the effect of unwanted signals which occur on the supply
mains (see also 5.3).
The connection between the artificial mains V-network and the measuring receiver shall be
made by means of a coaxial cable with a characteristic impedance of 50 Ω.
5.1.3 Voltage probe
The voltage probe shall be used when measuring on terminals other than mains terminals

(see 5.2.3.2) e.g. load and control terminals (5.2.4.4). The voltage probe shall also be used
on mains terminals when the artificial mains V-network cannot be used without unduly
influencing the equipment under test or the test equipment, e.g. while measuring motors and
heating devices operating at more than 25 A per phase.
The voltage probe contains a resistor having a resistance value of at least 1 500 Ω

1.1 La présente norme s'applique aux perturbations radioélectriques conduites et rayonnées,
produites par des appareils dont les fonctions principales sont assurées par des moteurs et
par des dispositifs de commutation ou des dispositifs de régulation, sauf si l'énergie RF est
produite volontairement, ou destiné à l'éclairage.
Elle concerne des appareils tels que: les appareils électrodomestiques, les outils électriques,
les dispositifs de commande et de régulation comportant des dispositifs à semiconducteurs,
les appareils électromédicaux à moteur, les jouets électriques/électroniques, les distributeurs
automatiques ainsi que les projecteurs de cinéma ou de diapositives.

4 Limites des perturbations
Sauf spécifications contraires données dans la présente norme pour des appareils

particuliers, il n'est pas nécessaire d'effectuer des mesures pour des perturbations radio-

électriques à des fréquences inférieures à 148,5 kHz ou supérieures à 300 MHz.
4.1 Perturbations continues
Les moteurs à collecteur ainsi que d'autres dispositifs qui sont incorporés dans les appareils
électrodomestiques, dans les outils électriques et dans les appareils électriques analogues,
peuvent produire des perturbations continues.
Les perturbations continues peuvent être soit du type à large bande, provoquées par des
dispositifs de commutation tels que: interrupteurs mécaniques, commutateurs et dispositifs de
régulation à semiconducteurs, soit du type à bande étroite, provoquées par des dispositifs de
commande électroniques tels que des microprocesseurs.
NOTE Dans la présente norme, une distinction a été faite entre deux types de perturbations, définis par le type de
détecteur utilisé, au lieu de parler de perturbations «à large bande» et «à bande étroite». Dans ce but, les limites
ont été définies conformément aux mesures réalisées avec un détecteur de valeur quasi-crête et avec un détecteur
de valeur moyenne (voir 5.1.1 et 6.1.1).
4.1.1 Bande de fréquences de 148,5 kHz à 30 MHz (tensions aux bornes)
NOTE En 1979, la Conférence Administrative Mondiale pour les Radiocommunications (CAMR) a réduit la limite
inférieure de la fréquence dans la Région 1 à 148,5 kHz; en ce qui concerne les applications couvertes par le
domaine d'application de la présente norme, les essais effectués à une fréquence de 150 kHz sont considérés
comme adéquats, car la fréquence de 148,5 kHz se trouve dans la bande passante du récepteur.
Le Tableau 1 donne les limites des tensions perturbatrices aux bornes. Les tensions aux
bornes sont mesurées, conformément à l'Article 5, sur chaque borne par rapport à la terre.
Les bornes sont définies comme des parties conductrices, adaptées au raccordement
électrique réutilisable avec des circuits externes.
4.1.1.1 Les limites indiquées dans les colonnes 2 et 3 doivent être respectées sur la (les)
phase(s) et le neutre des bornes d'alimentation de tous les appareils, à l'exception de celles
des outils électriques.
4.1.1.2 Les limites relatives aux "bornes supplémentaires" et spécifiées dans les colonnes 4
et 5, s'appliquent aux bornes supplémentaires des appareils ainsi qu'aux bornes de charge et
aux bornes supplémentaires des éléments de commande incorporant des dispositifs à
semiconducteurs.
Les bornes susceptibles d'être utilisées soit en tant que bornes d'alimentation, soit en tant
que bornes de charge/bornes supplémentaires, sont soumises aux limites applicables aux
bornes d'alimentation.
Aucune limite de tension aux bornes ne s’applique aux cordons, qui ne peuvent pas être
facilement rallongés par l’utilisateur (cordons reliés à demeure ou munis d’un connecteur
spécifique), dont la longueur ne dépasse pas 2 m, et qui relient l’appareil à un appareil ou
dispositif auxiliaire (par exemple commandes de vitesse à semiconducteurs, bloc
d’alimentation sur prise avec convertisseur alternatif/continu).

– 24 – CISPR 14-1  CEI:2005
Aucune limite de tension aux bornes ne s’applique aux cordons incorporés dans le tube
d’aspiration des aspirateurs, même si la longueur dépasse 2 m.

NOTE Voir 5.2.4 pour ce qui concerne la mesure aux bornes d'alimentation et aux bornes supplémentaires des

dispositifs de commande et de régulation comportant des dispositifs à semiconducteurs, et voir 5.2.3 pour ce qui
concerne les bornes supplémentaires d'autres appareils.

4.1.1.3 Pour les tensions perturbatrices aux bornes d'alimentation des outils électriques, les
limites particulières spécifiées dans les colonnes 6 à 11 sont applicables, en fonction de la
puissance assignée du moteur, à l'exclusion de la puissance de tout dispositif de chauffage

(par exemple, la puissance de chauffage d'un pistolet à air chaud pour le soudage des

matières plastiques). Pour les tensions perturbatrices aux bornes de la charge et aux bornes

supplémentaires des outils électriques, les valeurs spécifiées dans les colonnes 4 et 5 sont
applicables, sans exemption supplémentaire.

* Si la limite définie pour la mesure avec le détecteur de valeur moyenne est respectée en utilisant un récepteur à
détecteur de quasi-crête, le matériel soumis aux essais doit être considéré comme respectant les deux limites
et la mesure avec un récepteur équipé d'un détecteur de valeur moyenne n'est pas nécessaire.

NOTE Les limites spécifiées pour les mesures effectuées avec un détecteur de valeur moyenne sont des valeurs
provisoires, et peuvent être modifiées après une période expérimentale.
4.1.1.4 Les limites pour les électrificateurs de clôtures s'appliquent
a) aux bornes de clôture pour tous les électrificateurs (colonnes 4 et 5 du Tableau 1);
b) aux bornes d'alimentation basse tension pour les électrificateurs conçus pour être
raccordés à l'alimentation secteur (colonnes 2 et 3 du Tableau 1);

– 26 – CISPR 14-1  CEI:2005
c) aux bornes d'alimentation batterie pour les électrificateurs conçus pour fonctionner à

partir d'une batterie (colonnes 4 et 5 du Tableau 1).

Toutefois, aucune limite n'est applicable aux bornes d'alimentation batterie des électri-
ficateurs à batteries incorporées qui ne peuvent pas être raccordés à l'alimentation secteur,

ou des électrificateurs à batterie extérieure si la longueur du cordon de raccordement reliant

l'électrificateur à la batterie est inférieure à 2 m et n'est pas facilement extensible par

l'utilisateur sans employer d'outils spéciaux.

Les électrificateurs de type D, conformément à la CEI 60335-2-76, sont mesurés comme des

électrificateurs fonctionnant à partir d'une batterie avec un cordon de raccordement, reliant

l'électrificateur à la batterie, de longueur supérieure à 2 m.

NOTE En pratique le fil de la clôture peut également être une source de perturbation, à cause des décharges
haute tension, particulièrement pour les radiocommunications et les réseaux de télécommunications. Il convient
que les fabricants d'électrificateurs de clôture demandent aux utilisateurs d'éliminer les points de décharge tels
que le contact avec la végétation ou la rupture d'un fil de clôture.
4.1.1.5 Pour les appareils alimentés par piles ou batteries (incorporées ou extérieures)
susceptibles d'être raccordés au réseau d'alimentation (secteur), les limites spécifiées dans
les colonnes 2 et 3 du Tableau 1 sont applicables aux bornes d'alimentation.
Aucune limite de perturbation radioélectrique n'est applicable aux appareils à piles ou
batteries incorporées ne pouvant pas être raccordés à l'alimentation secteur.
Aucune limite de perturbation radioélectrique n'est applicable aux appareils à piles ou
batteries extérieures, si la longueur du cordon de raccordement reliant l'appareil à la pile ou à
la batterie est inférieure à 2 m. Si la longueur du cordon de raccordement est supérieure à
2 m ou si elle est facilement extensible par l'utilisateur sans employer d'outils spéciaux, les
limites spécifiées dans les colonnes 4 et 5 du Tableau 1 s'appliquent alors à ces cordons.
4.1.2 Bande de fréquences de 30 MHz à 300 MHz (puissance perturbatrice)
Les limites de la puissance perturbatrice sont données dans le Tableau 2.
La puissance perturbatrice est mesurée au niveau de chaque borne, conformément à l'Article 6.

la mesure avec un récepteur équipé d'un détecteur de valeur moyenne n'est pas nécessaire.
NOTE Les limites spécifiées pour les mesures effectuées avec un détecteur de valeur moyenne sont des valeurs
provisoires, et peuvent être modifiées après une période expérimentale.
4.1.2.1 Les limites spécifiées dans les colonnes 2 et 3 du Tableau 2 doivent être respectées
pour tous les appareils, à l'exception des appareils mentionnés à l'alinéa 2 de 4.1.2.2 à
4.1.2.4.
– 28 – CISPR 14-1  CEI:2005
4.1.2.2 Pour les appareils alimentés par piles ou batteries (incorporées ou extérieures)
susceptibles d'être raccordés au secteur, les limites spécifiées dans les colonnes 2 et 3 du

Tableau 2 ainsi que les exigences en 4.1.2.3 et 4.1.2.4 sont applicables.

Aucune limite de puissance perturbatrice n'est applicable aux appareils à piles ou batteries

incorporées ne pouvant être raccordés à l'alimentation secteur.

4.1.2.3 Pour les outils électriques, les limites spécifiques indiquées dans les colonnes 4 à 9

du Tableau 2 sont applicables, en fonction de la puissance assignée du moteur, à l'exclusion

de la puissance de tout dispositif de chauffage (par exemple, la puissance de chauffage d'un

pistolet à air chaud pour le soudage des matières plastiques).

4.1.2.4 Les dispositifs de contrôle de régulation comportant des semiconducteurs, les
électrificateurs de clôture, les redresseurs, les chargeurs de batteries et les convertisseurs
qui ne contiennent aucun générateur interne de fréquences ni horloge interne fonctionnant
au-dessus de 9 kHz ne font pas l'objet de limites pour la puissance perturbatrice dans la
bande de fréquences de 30 MHz à 300 MHz.
4.1.3 Bande de fréquences de 30 MHz à 1 000 MHz (puissance perturbatrice)
Les limites des perturbations rayonnées sont données dans le Tableau 3.

La limite inférieure est applicable à la fréquence de transition.

Les exigences concernant les perturbations rayonnées indiquées dans cette norme sont
restreintes aux jouets. Les mesures peuvent être réalisées à une distance d’essai réduite,
pouvant être abaissée jusqu’à 3 m. Afin de déterminer la conformité, un facteur inverse
proportionnel de 20 dB par décade doit être utilisé pour corréler les mesures en fonction de la
distance spécifiée ci-dessus.
En cas de conflit, les mesures aux distances spécifiées dans le rapport d’essai seront

vérifiées.
4.2 Perturbations discontinues
Les opérations de commutation qui ont lieu dans les appareils commandés par thermostat,
dans les machines automatiques programmées et autres appareils à commande électrique,
produisent des perturbations discontinues. L'effet subjectif des perturbations discontinues
varie avec la fréquence de répétition et l'amplitude des signaux audio et des signaux vidéo
générés. Par conséquent, une distinction est faite entre différents types de perturbations
discontinues.
Les perturbations discontinues sont uniquement mesurées à l'aide d'un récepteur de mesure
comportant un détecteur de quasi-crête, comme mentionné en 5.1.1 et comme spécifié à
l'Article 4 de la CISPR 16-1-1.
L'Annexe C fournit des recommandations.

– 30 – CISPR 14-1  CEI:2005
4.2.1 Les limites applicables aux perturbations discontinues dépendent principalement du

caractère des perturbations et du taux de répétition des claquements N, comme cela est

indiqué de manière détaillée en 4.2.2 et 4.2.3.

Aucune limite n'est applicable aux perturbatio

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.

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:2005CISPR 14-1 © IEC:2005 –– 25 13 – –

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 14 – – CISPR 14-1 © IEC:2005

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.

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.
4.1.2.1 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.

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.
Table 3 – Radiated disturbance limits for toys for the frequency range
30 MHz to 1 000 MHz at 10 m distance from the source
Frequency range Limits
dB(μV/m)
MHz
Quasi-peak
30 to 230 30
230 to 1 000 37
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 16 – – CISPR 14-1 © IEC:2005

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;

CISPR 14-1 © IEC:2005CISPR 14-1 © IEC:2005 –– 33 17 – –

c) the control of energy or speed by switching between a limited number of fixed positions;

d) the changing of the manual setting of a continuously adjustable control such as a

variable speed device for water extraction or electronic thermostats, is to be disregarded

for the purpose of testing the appliance for compliance with the limits of radio disturbance

set out in this standard.
Examples of switches included in this subclause are the on/off switches for apparatus

(including foot activated), for instance the switch for an electric typewriter, manual switches

for heat and air flow control in fan heaters and hair dryers, as well as the indirectly operated

switch in a cupboard, wardrobe or refrigerator, and sensor-operated switches, etc. Switches
which usually will be repeatedly operated are not included in this subclause, e.g. for sewing

machines, calculating machines, soldering equipment, etc. (see 7.2.3. and 7.3.2.4.c).

Also the disturbance caused by the operation of any switching device or control which is
included in an appliance for the purpose of mains disconnection for safety only, is to be
disregarded for the purpose of testing the appliance for compliance with the limits of radio
disturbance as described in this standard.
4.2.3.2 Combination of clicks in a time frame less than 600 ms
In programme controlled appliances a combination of clicks in a time frame less than 600 ms
is allowed once per selected programme cycle.
For other appliances such a combination of clicks is allowed once during the minimum
observation time. This is also valid for thermostatically controlled three-phase switches,
causing three disturbances sequentially in each of the three phases and the neutral. The
combination of clicks is considered as one click.
4.2.3.3 Instantaneous switching
Appliances which fulfil the following conditions:
– the click rate is not more than 5,
– none of the caused clicks has a duration longer than 20 ms,
– 90 % of the caused clicks have a duration less than 10 ms,
shall be deemed to comply with the limits, independent of the amplitude of the clicks (see
tables A.1 and A.2). If one of these conditions is not satisfied then the limits in accordance

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.

Part 1: Emission
1 Scope
1.1 This standard applies to the conduction and radiation of radio-frequency disturbances
from appliances whose main functions are performed by motors, switching or regulating
devices, or by r.f. generators used in induction cooking appliances.
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. Both mains
powered appliances and battery powered appliances are included.
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 (other than induction cooking) 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;
− arc welding equipment: CISPR 11.
– 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.
NOTE 3 Until induction cooking appliances are removed from the scope of CISPR 11, either CISPR 11 or
CISPR 14-1 may be chosen for compliance.
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.

click
a disturbance, the amplitude of which exceeds the quasi-peak limit of continuous disturbance,
the duration of which is not longer than 200 ms and which is separated from a subsequent
disturbance by at least 200 ms. The durations are determined from the signal which exceeds
the i.f. reference level of the measuring receiver
A click may contain a number of impulses; in which case the relevant time is that from the
beginning of the first to the end of the last impulse.
NOTE Under certain conditions, some kinds of disturbances are exempted from this definition (see 4.2.3)
3.3
i.f. reference level
the corresponding value on the intermediate frequency output of the measuring receiver of an
unmodulated sinusoidal signal which produces a quasi-peak indication equal to the limit for
continuous disturbance
3.4
switching operation
one opening or one closing of a switch or contact
NOTE Independent of whether clicks are observed or not.
3.5
minimum observation time
T

4 Limits of disturbance
Radio disturbance measurements below 148,5 kHz and above 1 000 MHz do not need to be
carried out. The requirements for induction cooking appliances are given in Annex B.
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.

CISPR 14-1  IEC:2005+A1:2008 – 13 –
+A2:2011
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).
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.

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);
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 1 000 MHz
4.1.2.1 Disturbance power measurement in the frequency range 30 MHz to 300 MHz
The limits of the disturbance power are given in Table 2a. Disturbance power is measured in

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

4 Limits of disturbance
Radio disturbance measurements below 148,5 kHz and above 1 000 MHz do not need to be
carried out.
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+A1:2008 – 13 –
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);
c) the battery terminals on energizers designed for operation from a battery (columns 4 and
5 of Table 1).
– 14 – CISPR 14-1 © IEC:2005+A1:2008
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 1 000 MHz
4.1.2.1 Disturbance power measurement in the frequency range 30 MHz to 300 MHz
The limits of the disturbance power are given in Table 2a. Disturbance power is measured in

4.1.2.3 Application of the limits
4.1.2.3.1 General
This subclause describes application of the limits for all appliances (see Figure 10).
Regulating controls which incorporate semiconductor devices, electric fence energizers,
rectifiers, battery chargers and converters, which do not contain any clock frequency higher
than 9 kHz, are not subject to the requirements in the frequency range 30 MHz to 1 000 MHz.
4.1.2.3.2 Mains operated appliances
The equipment under test shall be evaluated for emissions in the 30 MHz to 1 000 MHz range
by testing in accordance with either method 0 or 0, see also Figure 10.
a) The limits in columns 2 and 3 of Table 2a for the frequency range from 30 MHz to
300 MHz shall be met by all appliances except for electric tools. For electric tools the
particular limits given in columns 4 to 9 of Table 2a apply according to the rated power of
the motor, excluding the power of any heating device (for instance heating power in a
blower for plastic welding).
Appliances are deemed to comply in the frequency range from 300 MHz to 1 000 MHz if
both of the following conditions ( 1 ) an d 2)) are fulfilled:
1) all emission readings from the equipment under test shall be lower than the applicable
limits (Table 2a) reduced by the margin (Table 2b);
2) the maximum clock frequency shall be less than 30 MHz.
If either of condition 1) o r 2) is not fulfilled, radiated measurements in the frequency range
from 300 MHz to 1 000 MHz shall be conducted and the limits of Table 3 for that range
applied. In any case the limits of Table 2a in the frequency range 30 MHz to 300 MHz
shall be met.
b) The limits in Table 3 shall be met. Any of the measurement methods mentioned in Table 3
can be selected by the manufacturer except that the TEM-waveguide shall be used only
for battery powered appliances not intended to have external cables attached (see also
Note c in Table 3).
The test report shall state which method was used and which limits were applied.
