(Main)Household and similar electrical appliances - Safety - Part 2-17: Particular requirements for blankets, pads, clothing and similar flexible heating appliances
Household and similar electrical appliances - Safety - Part 2-17: Particular requirements for blankets, pads, clothing and similar flexible heating appliances
IEC 60335-2-17:2022 deals with the safety of electric blankets, pads, clothing and other flexible appliances that heat the bed or human body, for household and similar purposes, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances.
This standard also applies to control units supplied with the appliance.
Appliances not intended for normal household use but which nevertheless possibly pose be a source of danger to the public, such as appliances intended to be used in beauty parlours or by persons in cold ambient temperatures, are within the scope of this standard.
Requirements and tests for clothing are given in normative Annex CC.
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.
Children are considered to be old enough to use an appliance without supervision when they have been adequately instructed by a parent or guardian and are deemed competent to use the appliance safely.
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
– 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);
– rigid bed warmers, such as those of metal or ceramic material;
– water bed heaters (IEC 60335-2-66);
– heating appliances for breeding and rearing animals (IEC 60335-2-71);
– foot warmers and heating mats (IEC 60335-2-81);
– appliances specifically intended for use under medical supervision (IEC 60601-2-35);
– heated carpets (IEC 60335-2-106).
This fourth edition cancels and replaces the third edition published in 2012, Amendment 1:2015 and Amendment 2:2019. 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, 19.106, 21.103, 21.104, 21.110, 30.1, 30.102, Annex BB, CC.19.3);
c) clarification of the definition of control unit (3.6.105);
d) revision for adjusting the supply voltage of appliances, other than controlled appliances, when operation at rated power input times a factor is specified (5.12);
e) clarification of testing of blankets that cannot be folded with five thicknesses (19.101);
f) updated compliance criteria to include breakage of electrodes (21.1);
g) clarification of the test method for mattresses based on the rigidity index of the flexible part (21.111.1, Annex DD);
h) clarification for testing heating elements with a non-circular construction (21.111.3);
i) addition of requirements to protect the user from overheating in the event of an interruption in the mains supply (22.110)
j) inclusion of pressure test method from IEC 60320-1:2001 (30.1);
k) update of test methods for resistance to fire tests (30.101.1, 30.102).
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-17: Exigences particulières pour les couvertures, coussins, vêtements et appareils chauffants souples analogues
L'IEC 60335-2-17:2022 traite de la sécurité des couvertures, coussins, vêtements et autres appareils électriques souples, destinés à chauffer un lit ou le corps humain, pour usages domestiques et analogues, et dont la tension assignée des appareils est inférieure ou égale à 250 V, y compris les appareils alimentés en courant continu et les appareils alimentés par batteries.
La présente norme s'applique également aux unités de commande fournies avec l'appareil.
Les appareils non 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 dans les instituts de beauté ou par des personnes à des températures ambiantes froides, sont compris dans le domaine d'application de la présente norme.
Les exigences et les essais relatifs aux vêtements sont donnés à l'Annexe CC normative.
Dans la mesure du possible, la présente norme traite des dangers courants que présentent les appareils et auxquels sont exposés tous les individus situés 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;
– des enfants qui jouent avec l'appareil.
Les enfants sont considérés comme étant suffisamment âgés pour utiliser un appareil sans surveillance lorsque les parents ou les personnes qui en ont la garde leur ont expliqué les instructions et qu'ils sont ainsi aptes à utiliser l'appareil en toute sécurité.
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 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 dispositifs de chauffage rigides des lits, comme ceux en métal ou en céramique;
– aux dispositifs de chauffage pour matelas à eau (IEC 60335-2-66);
– aux appareils de chauffage destinés à la reproduction et à l'élevage des animaux (IEC 60335-2-71);
– aux chancelières et carpettes chauffantes (IEC 60335-2-81);
– aux appareils spécifiquement destinés à être utilisés sous surveillance médicale (IEC 60601-2-35);
– aux tapis chauffants (IEC 60335-2-106).
Cette quatrième édition annule et remplace la troisième édition parue en 2012, l'Amendement 1:2015 et l'Amendement 2:2019. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le texte a été aligné sur l'IEC 60335-1:2020;
b) certaines notes ont été converties en texte normatif (Article 1, 19.106, 21.103, 21.104, 21.110, 30.1, 30.102, Annexe BB, CC.19.3);
c) la définition d'une unité de commande a été explicitée (3.6.105);
d) le réglage de la tension d'alimentation des appareils, autres que les appareils régulés, lorsque leur fonctionnement à la puissance assignée multipliée par un facteur est spécifié, a été révisé (5.12);
e) les essais des couvertures qui ne peuvent pas être pliées en cinq épaisseurs ont été explicités (19.101);
f) les critères de conformité ont été mis à jour afin d'inclure la rupture des électrodes (21.1);
g) la méthode d'essai des matelas en fonction de l'indice de rigidité de la partie souple a été explicitée (21.111.1, Annexe DD);
h) les essais des éléments chauffants à construction non circulaire ont été explicités (21.111.3);
i) des exigences ont été ajou

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.
