IEC 60335-2-11:2019

Household and similar electrical appliances - Safety - Part 2-11: Particular requirements for tumble dryers

IEC 60335-2-11:2019 is available as IEC 60335-2-11:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60335-2-11:2019 deals with the safety of electric tumble dryers intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. This standard applies to the drying function of washing machines having a drying cycle. This standard also deals with the safety of tumble dryers that use a refrigerating system, incorporating sealed motor-compressors, for drying textile material. These appliances may use flammable refrigerants. Additional requirements for these appliances are given in Annex AA. 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. Examples of such appliances are tumble dryers for communal use in blocks of flats or in launderettes. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons. 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 may be necessary;
– in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities,
This standard does not apply to:
– appliances intended exclusively for industrial purposes;
– 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);
– appliances incorporating steam generating devices in which steam is produced at a pressure exceeding 50 kPa.
This eighth edition cancels and replaces the seventh edition published in 2008, Amendment 1:2012 and Amendment 2:2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the seventh edition:
– aligns the text with IEC 60335-1, Ed 5, and its Amendments 1 and 2;
– some notes have been converted to normative text (7.12, 7.12.1, 11.3, 19.101, AA.5.2);
– more detailed test specifications have been given in 11.3 and 15.2;
– specific requirements have been added in 3.1.9, 3.6.101, 7.12, 11.7, 19.1, and Clause 22 to cover appliances with steam generators;
– specific requirements have been added in 22.108 to cover programmable electronic circuits;
– Annex AA has been deleted, because it is covered by Part 1 and the remaining annexes have been renumbered.
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 2-11: Exigences particulières pour les sèche-linge à tambour

IEC 60335-2-11:2019 est disponible sous forme de IEC 60335-2-11:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 60335-2-11:2019 traite de la sécurité des sèche-linge à tambour électriques pour usages domestiques et analogues dont la tension assignée n’est pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils. La présente norme s'applique à la fonction de séchage des machines à laver le linge ayant un cycle de séchage. La présente norme traite également de la sécurité des sèche-linge à tambour utilisant un système de réfrigération à motocompresseurs hermétiques pour sécher le linge. Ces appareils peuvent utiliser des fluides frigorigènes inflammables. Des exigences supplémentaires pour ces appareils sont données à l’Annexe AA. Les appareils non destinés à un usage domestique normal mais qui néanmoins peuvent constituer une source de danger pour le public, tels que les appareils destinés à être utilisés par des usagers non avertis dans des magasins, chez des artisans et dans des fermes, relèvent du domaine d'application de la présente norme. Les sèche-linge à tambour mis à la disposition commune des usagers dans les immeubles d’habitation ou dans les blanchisseries automatiques sont des exemples de tels appareils. Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les appareils, encourus par toutes les personnes. Cependant, la présente norme ne tient généralement pas compte:
– des personnes (y compris des enfants) dont les capacités physiques, sensorielles ou mentales; ou le manque d’expérience et de connaissance les empêche(nt) 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 les organismes nationaux responsables de l'alimentation en eau;
La présente norme ne s'applique pas:
– aux appareils prévus exclusivement pour des usages industriels;
– 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);
– aux appareils équipés de dispositifs générant de la vapeur dans lesquels la vapeur est produite à une pression dépassant 50 kPa.
Cette huitième édition annule et remplace la septième édition parue en 2008, l'Amendement 1:2012 et l'Amendement 2:2015. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à la septième édition:
– alignement du texte sur l’IEC 60335-1, Éd. 5, et ses Amendements 1 et 2;
– conversion de certaines notes en texte normatif (7.12, 7.12.1, 11.3, 19.101, AA.5.2);
– modalités d’essai plus amplement détaillées en 11.3 et en 15.2;
– ajout d’exigences spécifiques en 3.1.9, 3.6.101, 7.12, 11.7, 19.1 et à l’Article 22 pour couvrir les appareils à générateurs de vapeur;
– ajout d’exigences spécifiques en 22.108 pour couvrir les circuits électroniques programmables;
– suppression de l’Annexe AA puisque son contenu est couvert par la Partie 1, et renumérotation des annexes restantes.
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.
