IEC 60335-2-7:2019

Household and similar electrical appliances - Safety - Part 2-7: Particular requirements for washing machines

IEC 60335-2-7:2019 deals with the safety of electric washing machines for household and similar use, that are intended for washing clothes and textiles, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. This standard also deals with the safety of electric washing machines for household and similar use employing an electrolyte instead of detergent. Additional requirements for these appliances are given in Annex CC. Guidance is given in Annex DD for requirements that can be used to ensure an acceptable level of protection against electrical and thermal hazards for washing machines fitted with a power driven wringer. 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 washing machines for communal use in blocks of flats or in launderettes. As far as is practicable, this standard deals with the common hazards presented by washing machines 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 washing machines 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 and similar authorities.
This standard does not apply to:
– washing machines intended exclusively for industrial purposes (ISO 10472-2);
– 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);
– washing machines 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: 2011 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
– requirements for steam generators in 3.1.9, 3.6.101, 19.101, 22.106, 22.107;
– additional definitions for washing machine types in 3.5.101,3.5.102, 3.5.103;
– revised temperature limits for external accessible surfaces in 11.3 and 11.8;
– revised test procedure for the spillage test in 15.2;
– additional requirements for appliances that are controlled by programmable electronic circuits that limit the number of heating elements and motors from being energised at the same time, Subclause 22.108.
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 2-7: Exigences particulières pour les machines à laver le linge

L'IEC 60335-2-7:2019 traite de la sécurité des machines à laver le linge électriques pour usages domestiques et analogues destinées à laver des vêtements et des textiles, 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 traite également de la sécurité des machines à laver le linge électriques pour usages domestiques et analogues employant un électrolyte à la place d’un détergent. Les exigences complémentaires pour ces appareils sont données à l’Annexe CC. Des recommandations sont données à l’Annexe DD pour les exigences qui peuvent être utilisées pour assurer un niveau acceptable de protection contre les dangers électriques et thermiques pour les machines à laver le linge comportant une essoreuse à rouleaux entraînés par moteur. 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 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. Les machines à laver le linge mises à la disposition commune des utilisateurs dans des immeubles d'habitation ou dans les laveries automatiques sont des exemples de tels appareils. Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les machines à laver le linge qui sont 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 machines à laver le linge destinées à être utilisées 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, par les organismes nationaux responsables de l'alimentation en eau et par des organismes similaires.
La présente norme ne s’applique pas:
– aux machines à laver le linge prévues exclusivement pour des usages industriels (ISO 10472-2);
– 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 machines à laver le linge équipées de dispositifs générant de la vapeur qui est produite à une pression dépassant 50 kPa.
Cette huitième édition annule et remplace la septième édition parue en 2008, l'Amendement 1:2001 et l'Amendement 2:2016. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
– exigences relatives aux générateurs de vapeur, en 3.1.9, 3.6.101, 19.101, 22.106 et 22.107;
– définitions supplémentaires concernant les types de machines à laver le linge, en 3.5.101, 3.5.102 et 3.5.103;
– révision des limites de température pour les surfaces accessibles externes, en 11.3 et 11.8;
– révision de la procédure de l’essai de débordement, en 15.2;
– exigences supplémentaires relatives aux appareils commandés par des circuits électroniques programmables qui limitent le nombre d’éléments chauffants et de moteurs alimentés simultanément, en 22.108. 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.
