IEC 60335-1:2010

Household and similar electrical appliances - Safety - Part 1: General requirements

IEC 60335-1:2010 deals with the safety of electrical appliances for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Battery-operated appliances and other d.c. supplied appliances are within the scope of this standard. 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 catering equipment, cleaning appliances for commercial use, and appliances for hairdressers. The principal changes in this edition as compared with the fourth edition are as follows:
- updated the text of the standard to align with the most recent editions of the dated normative references;
- modified the functional safety requirements using programmable electronic circuits including software validation requirements;
- updated Clause 29 to cover insulation requirements subjected to high frequency voltages as in switch mode power supply circuits;
- updated Subclause 30.2 to further align the pre-selection option with the end-product test option;
- deleted some notes and converted many other notes to normative text;
- clarified requirements for class III constructions.
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. The contents of the corrigenda of July 2010 and April 2011 have been included in this copy.

Appareils électrodomestiques et analogues - Sécurité - Partie 1: Exigences générales

La CEI 60335-1:2010 traite de la sécurité des appareils 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. Les appareils alimentés par batteries et les autres appareils alimentés en courant continu sont compris dans le domaine d'application de la présente norme. 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, sont compris dans le domaine d'application de la présente norme. Comme exemples de tels appareils, on peut citer le matériel de restauration, les appareils de nettoyage à usage commercial et les appareils pour les coiffeurs. Les principales modifications de la présente édition par rapport à la quatrième édition sont les suivantes:
- mise à jour du texte pour aligner la norme avec les éditions les plus récentes des références normatives datées;
- modification des exigences de sécurité fonctionnelle utilisant des circuits électroniques programmables, y compris les exigences de validation des logiciels;
- mise à jour de l'Article 29 pour couvrir les exigences de l'isolation soumise à des tensions à fréquence élevée comme, par exemple, dans les circuits d'alimentation à découpage;
- mise à jour du Paragraphe 30.2 pour mieux aligner les options de présélection avec les options d'essai du produit fini;
- suppression de quelques notes et conversion de plusieurs autres notes en texte normatif;
- clarification des exigences pour les parties de la classe III.
L'attention des Comités Nationaux est attirée sur le fait que les fabricants d'appareils et les organismes d'essai peuvent avoir besoin d'une période transitoire après la publication d'une nouvelle publication CEI, ou d'une publication amendée ou révisée, pour fabriquer des produits conformes aux nouvelles exigences et pour adapter leurs équipements aux nouveaux essais ou aux essais révisés. Le comité recommande que le contenu de cette publication soit entériné au niveau national au plus tôt 12 mois et au plus tard 36 mois après la date de publication. Le contenu des corrigenda de juillet 2010 et avril 2011 a été pris en considération dans cet exemplaire.

Introduction
Amendment 2 of IEC 60335-1:2010 defines and introduces requirements for a detachable
power supply part of an appliance. In this amendment, 24.2 prohibits the use of a power
supply in a flexible cord.
QUESTION:
Does Subclause 24.2 prohibit the use of a detachable power supply part?
ANSWER
No, a “detachable power supply part” is a defined term and is not captured by term “power
supply” as used in Subclause 24.2.

NOTE A detachable power supply part is captured by the defined term when the output of the power supply part is
detachable from the class III construction part of the appliance at:
– the power supply part, or
– the class III construction part of the appliance.
However, the supply cord (if any) does not have to be detachable from the detachable power supply part.
