Household and similar electrical appliances - Safety - Part 2-108: Particular requirements for electrolysers

This European standards Deals with the safety of electrolysers that produce low viscosity, ionized liquids intended for use as detergent free wash water in appliances for household and similar purposes and which conform with the standards applicable to such appliances. It applies to electrolysers tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V.

Appareils électrodomestiques et analogues - Sécurité - Partie 2-108: Règles particulières pour les électrolyseurs

L’IEC 60335-2-108:2024 traite de la sécurité des électrolyseurs qui produisent des liquides ionisés à faible viscosité destinés à être utilisés comme eau de lavage sans détergent dans les appareils à usages domestiques et analogues et qui sont conformes aux normes applicables à de tels appareils. Elle s’applique aux électrolyseurs soumis aux essais séparément, dans les conditions les plus sévères qui peuvent se produire en utilisation normale, et dont la tension assignée est inférieure ou égale à 250 V, y compris les appareils alimentés en courant continu et les appareils alimentés par batteries. Exemples d’appareils qui peuvent contenir des électrolyseurs: - les lave-vaisselle (IEC 60335-2-5); - les machines à laver le linge (IEC 60335-2-7); - les appareils produisant de l’eau de lavage à caractère hygiénique. La présente norme ne remplace pas les exigences des normes applicables aux appareils particuliers qui utilisent un électrolyseur. Toutefois, si l’électrolyseur utilisé est conforme à la présente norme, les essais spécifiés pour l’électrolyseur dans la norme de l’appareil particulier peuvent ne pas être nécessaires s’il est intégré dans l’appareil particulier ou fait partie d’un assemblage. Si le dispositif de commande de l’électrolyseur est associé au dispositif de commande de l’appareil particulier, des essais supplémentaires peuvent être nécessaires sur l’appareil final. Des recommandations pour les exigences supplémentaires à prendre en considération pour être rajoutées dans les normes de produit fini des appareils utilisant des électrolyseurs sont données à l’Annexe BB informative. 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'aéronefs, 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 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 deuxième édition annule et remplace la première édition parue en 2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) le texte a été aligné sur l'IEC 60335-1:2020; b) certaines notes ont été converties en texte normatif (Article 1, 22.012); c) introduction de l’application du calibre d’essai 19 (8.1.1, 20.2, B22.3, B22.4); d) ajout d’exigences relatives aux températures des surfaces accessibles extérieures (Article 11). La présente partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335-1:2020 et ses amendements sauf si cette édition l'exclut; dans ce cas, la dernière édition qui n'exclut pas la présente partie 2 est utilisée. Elle a été établie sur la base de la sixième édition (2020) de cette norme.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) p
