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.

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.

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 use
