(Main)Household and similar electrical appliances - Safety - Part 2-25: Particular requirements for microwave ovens, including combination microwave ovens
Household and similar electrical appliances - Safety - Part 2-25: Particular requirements for microwave ovens, including combination microwave ovens
IEC 60335-2-25:2019 deals with the safety of microwave ovens for household and similar use, their rated voltage being not more than 250 V.
This standard also deals with combination microwave ovens, for which Annex AA is applicable.
This standard also deals with microwave ovens intended to be used on board ships, for which Annex BB is applicable.
Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. However, if the appliance is intended to be used professionally to process food for commercial purposes, the appliance is not considered to be for household and similar use only.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account
– persons (including children) whose physical, sensory or mental capabilities or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
Attention is drawn to the fact that
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
– in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to
– commercial microwave ovens (IEC 60335-2-90);
– industrial microwave heating equipment (IEC 60519-6);
– appliances for medical purposes (IEC 60601);
– appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
This seventh edition cancels and replaces the sixth edition published in 2010, Amendment 1:2014 and Amendment 2:2015. This edition constitutes a technical revision.
This edition includes the following significant changes with respect to the sixth edition:
– 11.7 and 19.13 are improved in clarity;
– in 19.102, a note is converted into normative text;
– 19.101 is improved with an alternative measurement method;
– 22.121 is improved with requirements for simultaneous activation of heating elements and motors;
– 15.2, 15.101, 21, 22.102, 22.112, 22.119, 22.120, 24.101 and 27.1 are improved in clarity;
– Annex A has editorial improvements and feasible limits of deviations.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-25: Exigences particulières pour les fours à micro-ondes, y compris les fours à micro-ondes combinés
L'IEC 60335-2-25:2019 traite de la sécurité des fours à micro-ondes à usage domestique et analogue dont la tension assignée n'est pas supérieure à 250 V.
La présente norme traite également des fours à micro-ondes combinés, pour lesquels l'Annexe AA est applicable.
La présente norme traite également des fours à micro-ondes destinés à être utilisés à bord de navires, pour lesquels l'Annexe BB est applicable.
Les appareils qui ne sont pas destinés à un usage domestique normal, mais qui peuvent néanmoins constituer une source de danger pour le public, tels que les appareils destinés à être utilisés par des utilisateurs non avertis dans des magasins, chez des artisans et dans des fermes, sont compris dans le domaine d'application de la présente norme. Toutefois, si l'appareil est destiné à être utilisé par des professionnels pour la préparation d'aliments à des fins commerciales, l'appareil n'est pas vu comme étant uniquement à usage domestique et analogue.
Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les appareils, encourus par tous les individus à l'intérieur et autour de l'habitation. Cependant, la présente norme ne tient pas compte en général:
– des personnes (y compris des enfants) dont les capacités physiques, sensorielles ou mentales ou le manque d'expérience et de connaissance les empêchent d'utiliser l'appareil en toute sécurité sans surveillance ou instruction;
– de l'utilisation de l'appareil comme jouet par des enfants.
L'attention est attirée sur le fait que
– pour les appareils destinés à être utilisés dans des véhicules ou à bord de navires ou d'avions, des exigences supplémentaires peuvent être nécessaires;
– dans de nombreux pays, des exigences supplémentaires sont spécifiées par les organismes nationaux de la santé, par les organismes nationaux responsables de la protection des travailleurs et par des organismes similaires.
La présente norme ne s'applique pas
– aux fours à micro-ondes à usage commercial (IEC 60335-2-90);
– aux installations de chauffage industriel à micro-ondes (IEC 60519-6);
– aux appareils destinés à des usages médicaux (IEC 60601);
– aux appareils destinés à être utilisés dans des locaux présentant des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière, vapeur ou gaz).
Cette septième édition annule et remplace la sixième édition parue en 2010, l'Amendement 1:2014 et l'Amendement 2:2015. Cette édition constitue une révision technique.
Cette édition inclut les modifications majeures suivantes par rapport à la sixième édition:
– clarification de 11.7 et de 19.13;
– en 19.102, conversion d'une note en texte normatif;
– en 19.101, ajout d'une méthode de mesure alternative;
– en 22.121, ajout d'exigences relatives à l'activation simultanée des éléments de chauffage et des moteurs;
– clarification des 15.2, 15.101, 21, 22.102, 22.112, 22.119, 22.120, 24.101 et 27.1;
– amélioration rédactionnelle de l'Annexe A et introduction de limites d'écarts réalisables.
La présente partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335‑1 et ses amendements. Elle a été établie sur la base de la cinquième édition (2010) de cette norme.

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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change has
