Household and similar electrical appliances - Safety - Part 2-71: Particular requirements for electrical heating appliances for breeding and rearing animals

IEC 60335-2-71:2018 deals with the safety of all kinds of electrical heating appliances used for livestock rearing and breeding, such as: heat-radiating appliances, electrical sitting-hens, incubators, chicken breeding units and heating plates for animals, the rated voltage of the appliances being not more than 250 V for single-phase appliances and 480 V for other appliances. This standard applies to heating appliances used for livestock rearing and breeding that include an electrical motor. This standard does not apply to: - appliances designed 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); - heating units embedded in the floor; - flexible sheet heating elements for room heating (IEC 60335-2-96); - room heaters (IEC 60335-2-30). This third edition cancels and replaces the second edition published in 2002, its Amendment 1 (2007) and its Amendment 2 (2012). This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - two paragraphs are deleted (Introduction); - normative references updated (Clause 2); - colour required for symbols (7.6); - some notes converted to normative text (19.2, 21.101, 22.104).

Appareils électrodomestiques et analogues - Sécurité - Partie 2-71: Règles particulières pour les appareils de chauffage électrique destinés à la reproduction et à l'élevage des animaux

L'IEC 60335-2-71:2018 traite de la sécurité de tous types d'appareils de chauffage électrique destinés à la reproduction et à l'élevage des animaux, tels que: appareils de chauffage radiant, couveuses électriques, incubateurs, unités d'élevage de poulets et plaques chauffantes pour animaux dont la tension assignée des appareils est inférieure ou égale à 250 V pour les appareils monophasés et 480 V pour les autres appareils. La présente norme s'applique aux appareils de chauffage destinés à la reproduction et à l'élevage des animaux qui comportent un moteur électrique. 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 de chauffage encastrés dans le sol; - aux films souples chauffants pour le chauffage des locaux (IEC 60335-2-96); - aux appareils de chauffage des locaux (IEC 60335-2-30). Cette troisième édition annule et remplace la deuxième édition parue en 2002, son Amendement 1 (2007) et son Amendement 2 (2012). Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - deux alinéas ont été supprimés (Introduction); - les références normatives ont été mises à jour (Article 2); - les couleurs sont désormais exigées pour les symboles (7.6); - certaines notes ont été transformées en texte normatif (19.2, 21.101, 22.104).

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with 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 diverg
