IEC 60335-2-17-ed.4.0

Annotation of standard text IEC 60335-2-17-ed.4.0 :

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. LIEC 60335-2-17:2022 traite de la securite des couvertures, coussins, vetements et autres appareils electriques souples, destines a chauffer un lit ou le corps humain, pour usages domestiques et analogues, et dont la tension assignee des appareils est inferieure ou egale a 250 V, y compris les appareils alimentes en courant continu et les appareils alimentes par batteries. La presente norme sapplique egalement aux unites de commande fournies avec lappareil. Les appareils non destines a un usage domestique normal, mais qui peuvent neanmoins constituer une source de danger pour le public, tels que les appareils destines a etre utilises dans les instituts de beaute ou par des personnes a des temperatures ambiantes froides, sont compris dans le domaine dapplication de la presente norme. Les exigences et les essais relatifs aux vetements sont donnes a lAnnexe CC normative. Dans la mesure du possible, la presente norme traite des dangers courants que presentent les appareils et auxquels sont exposes tous les individus situes a linterieur et autour de lhabitation. Cependant, elle ne tient en general pas compte – des personnes (y compris des enfants) dont les capacites physiques, sensorielles ou mentales; ou le manque dexperience et de connaissance les empechent dutiliser lappareil en toute securite sans surveillance ou instruction; – des enfants qui jouent avec lappareil. Les enfants sont consideres comme etant suffisamment ages pour utiliser un appareil sans surveillance lorsque les parents ou les personnes qui en ont la garde leur ont explique les instructions et quils sont ainsi aptes a utiliser lappareil en toute securite. Lattention est attiree sur le fait que : – pour les appareils destines a etre utilises dans des vehicules ou a bord de navires ou davions, des exigences supplementaires peuvent etre necessaires; – dans de nombreux pays, des exigences supplementaires sont specifiees par les organismes nationaux de la sante, par les organismes nationaux responsables de la protection des travailleurs et par des organismes similaires. La presente norme ne sapplique pas : – aux appareils destines a etre utilises dans des locaux q
