IEC 60335-2-51:2019 est disponible sous forme de IEC 60335-2-51:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60335-2-51:2019 traite de la sécurité des pompes de circulation fixes électriques pour usages domestiques et analogues, destinées à être utilisées dans des installations de chauffage ou de distribution d'eau, dont la tension assignée n'est pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils. Les parties hydrauliques et électriques de la pompe peuvent être dans la même enveloppe, de sorte que l'eau s'écoule à travers le moteur et serve de liquide de refroidissement, ou elles peuvent être séparées. Les appareils non destinés à un usage domestique normal, mais qui peuvent néanmoins 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. Dans la mesure du possible, la présente norme traite des risques ordinaires présentés par les appareils, encourus par tous les individus à l’intérieur et autour de l'habitation. Cependant, cette norme ne tient pas compte en général: – des personnes (y compris des enfants) dontles 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 organismes nationaux de la santé, par les organismes nationaux responsables de la protection des travailleurs et par des organismes similaires. La présente norme ne s'applique pas: – aux pompes destinées à la circulation de liquides autres que l'eau; – aux pompes autres que les pompes de circulation (IEC 60335-2-41); – aux pompes de circulation destinées exclusivement aux usages industriels; – aux pompes de circulation destinées à être utilisées dans des locaux présentant des conditions particulières telles que la présence d'une atmosphère corrosive ou explosive (poussières, vapeur ou gaz). Cette quatrième édition annule et remplace la troisième édition parue en 2002, l'Amendement 1:2008 et l'Amendement 2:2011. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: – certaines instructions ne sont plus exigées (7.12); – certaines notes ont été converties en texte normatif (7.12.1, 11.3, 11.8); – nouvelles instructions d'installation de l'isolant thermique (7.12.1); – la valeur du courant de fuite a été modifiée (Article A.2). 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.

Part 2-51: Particular requirements for stationary circulation pumps
for heating and service water installations
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 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.
