IEC 60335-2-4:2021

Household and similar electrical appliances - Safety - Part 2-4: Particular requirements for spin extractors

IEC 60335-2-4:2021 deals with the safety of stand-alone electric spin extractors and spin extractors incorporated in washing machines that have separate containers for washing and spin extraction for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and a drum peripheral speed not exceeding 50 m/s, their rated voltages being not more than 250 V for single-phase appliances and 480 V for other appliances. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as spin extractors intended to be used by laymen in shops, in light industry and on farms, and spin extractors for communal use in blocks of flats or in launderettes, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by appliances which are encountered by all persons in and around the home.
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, the national water supply authorities and similar 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).
This seventh edition cancels and replaces the sixth edition published in 2008, Amendment 1:2012 and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- aligns the text with IEC 60335-1, Ed 5, and its Amendments 1 and 2;
- replacement of the term definition of accessible part to include test probe 18;
- addition of test probe 18 for accessibility of live parts.
This part 2 is to be used in conjunction with the fifth edition of IEC 60335-1:2010 and its amendments.

Appareils électrodomestiques et analogues - Sécurité - Partie 2-4: Exigences particulières pour les essoreuses centrifuges

L'IEC 60335-2-4:2021 traite de la sécurité:
- des essoreuses centrifuges électriques indépendantes, et
- des essoreuses centrifuges incorporées à des machines à laver le linge qui comportent des tambours distincts pour le lavage et l'essorage
pour usages domestiques et analogues dont la capacité ne dépasse pas 10 kg de linge sec, dont la vitesse périphérique du tambour ne dépasse pas 50 m/s et dont la tension assignée n'est pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils.
Les appareils non destinés à un usage domestique normal, mais qui peuvent néanmoins constituer une source de danger pour le public, tels que les essoreuses centrifuges destinées à être utilisées par des usagers non avertis dans des magasins, chez des artisans et dans des fermes, ainsi que les essoreuses centrifuges destinées à un usage collectif dans des immeubles d'habitation ou dans des laveries automatiques, relèvent du domaine d'application de la présente norme. Dans la mesure du possible, la présente norme traite des dangers ordinaires présentés par les appareils, encourus par tous les individus situés à l'intérieur et autour de l'habitation. Cependant, cette 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 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 autorités sanitaires nationales, les organismes nationaux en charge de la protection des travailleurs, les agences nationales de l'eau et des organismes analogues.
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).
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- alignement du texte sur l'IEC 60335-1, Ed 5 et ses Amendements 1 et 2;
- remplacement de la définition du terme "partie accessible" pour inclure le calibre d'essai 18;
- ajout du calibre d'essai 18 pour l'accès aux parties actives.
La présente partie 2 doit être utilisée conjointement avec l'IEC 60335-1:2010 et ses amendements.

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
