Appareils électrodomestiques et analogues - Sécurité - Partie 2-101: Exigences particulières pour les vaporisateurs

L’IEC 60335-2-101:2024 traite de la sécurité des vaporisateurs électriques pour usages domestiques et analogues dont la tension assignée est inférieure ou égale à 250 V, y compris les appareils alimentés en courant continu et les appareils alimentés par batteries. Exemples d’appareils relevant du domaine d’application de la présente norme: - diffuseurs; - appareils insectifuges. Ils peuvent être branchés directement dans un socle de prise de courant ou raccordés au réseau d’alimentation au moyen d’un câble souple et d’une fiche de prise de courant. Les appareils non destinés à un usage domestique normal mais qui peuvent néanmoins constituer une source de danger pour le public, par exemple les appareils destinés à être utilisés par des utilisateurs non avertis dans des magasins, chez des artisans et dans des fermes, relèvent du domaine d’application de la présente norme. Dans la mesure du possible, la présente norme traite des dangers courants que présentent les appareils et auxquels sont exposés tous les individus à l’intérieur et autour de l’habitation. Cependant, elle ne tient en général pas compte - 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 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 appareils prévus exclusivement pour des usages industriels; - aux appareils destinés à être utilisés dans des locaux qui présentent des conditions particulières, telles que la présence d’une atmosphère corrosive ou explosive (poussière, vapeur ou gaz); - aux appareils de chauffage des liquides (IEC 60335-2-15); - aux destructeurs d’insectes (IEC 60335-2-59); - aux appareils à vapeur pour tissus (IEC 60335-2-85); - aux humidificateurs (IEC 60335-2-98). Cette deuxième édition annule et remplace la première édition parue en 2002, son Amendement 1:2008 et son Amendement 2:2014. La présente édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) alignement sur l’IEC 60335-1:2020; b) transformation de certaines notes en texte normatif (Article 1, 7.1); c) introduction de l’application du calibre d’essai 19 (8.1.1, 8.1.3, 20.2, B.22.3, B.22.4); d) ajout d’exigences relatives aux températures des surfaces accessibles extérieures (Article 11). La présente Partie 2 doit être utilisée conjointement avec la dernière édition de l’IEC 60335-1 et ses amendements sauf si cette édition l’exclut; dans ce cas, la dernière édition qui n’exclut pas la présente Partie 2 est utilisée. Elle a été établie sur la base de la sixième édition (2020) 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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60335-2-101 has been prepared by IEC technical committee 61: Safety of household and
similar electrical appliances. It is an International Standard.
This second edition cancels and replaces the first edition published in 2002, Amendment 1:2008
and Amendment 2:2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) alignment with IEC 60335-1:2020;
b) conversion of some notes to normative text (Clause 1, 7.1);
c) application of test probe 19 has been introduced (8.1.1, 8.1.3, 20.2, B.22.3, B.22.4);
d) addition of external accessible surface temperatures (Clause 11).
