Household and similar electrical appliances - Safety - Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice makers

IEC 60335-2-24:2020 deals with the safety of the following appliances, their rated voltage being not more than 250 V for single-phase appliances, 480 V for other appliances and 24 V DC for appliances when battery operated:
– refrigerating appliances for household and similar use;
– ice-makers incorporating a motor-compressor and ice-makers intended to be incorporated in frozen food storage compartments;
– refrigerating appliances and ice-makers for use in camping, touring caravans and boats for leisure purposes.
These appliances may be operated from the mains, from a separate battery or operated either from the mains or from a separate battery.
This standard also deals with the safety of ice-cream appliances intended for household use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.
It also deals with compression-type appliances for household and similar use, which use flammable refrigerants.
This standard does not cover features of the construction and operation of those refrigerating appliances which are dealt with in other IEC standards.
Refrigerating appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as
– refrigerating appliances used in staff kitchen areas in shops, offices and other working environments,
– refrigerating appliances used in farm houses and by clients in hotels, motels and other residential type environments,
– refrigerating appliances used in bed and breakfast type environments, and
– refrigerating appliances used in catering and similar non-retail applications
are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account
– persons (including children) whose physical, sensory or mental capabilities or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
– children playing with the appliance.
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 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 to be used in the open air;
– 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);
– appliances incorporating a battery intended as a power supply for the refrigerating function;
– appliances assembled on site by the installer;
– appliances with remote motor-compressors;
– motor-compressors (IEC 60335-2-34);
– commercial dispensing appliances and vending appliances (IEC 60335-2-75);
– commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or motor-compressor (IEC 60335-2-89);
– professional ice-cream makers (IEC 60335-2-118).
This eighth edition cancels and replaces the seventh edition published in 2010, 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 5.2;

Appareils électrodomestiques et analogues - Sécurité - Partie 2-24: Exigences particulières pour les appareils de réfrigération, les sorbetières et les fabriques de glace

L'IEC 60335-2-24:2020 traite de la sécurité des appareils suivants, leur tension assignée n'étant pas supérieure à 250 V pour les appareils monophasés, à 480 V pour les autres appareils et à 24 V en courant continu pour les appareils alimentés par batteries:
– appareils de réfrigération pour usages domestiques et analogues;
– fabriques de glace comportant un motocompresseur et fabriques de glace conçues pour être incorporées dans des compartiments de stockage des denrées congelées;
– appareils de réfrigération et fabriques de glace à usage de loisir pour le camping, le caravaning ou le bateau.
Ces appareils peuvent être alimentés par le secteur, par une batterie séparée, ou être alimentés à la fois par secteur ou batterie.
La présente norme traite également de la sécurité des sorbetières à usage domestique, leur tension assignée n'étant pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils.
Elle traite également des appareils à compression pour usage domestique et analogue, qui utilisent des fluides frigorigènes inflammables.
La présente norme ne traite pas des caractéristiques de construction et de fonctionnement d'appareils de réfrigération qui font l'objet d'autres normes IEC.
Les appareils de réfrigération qui ne sont pas destinés à des usages domestiques normaux, mais qui peuvent néanmoins constituer une source de danger pour le public, tels que:
- les appareils de réfrigération utilisés dans les coins cuisines réservés au personnel des magasins, bureaux et autres environnements professionnels;
- les appareils de réfrigération utilisés dans les fermes et par les clients des hôtels, motels et autres environnements à caractère résidentiel;
- les appareils de réfrigération utilisés dans les environnements de type chambres d'hôtes; et
- les appareils de réfrigération utilisés en restauration et autres applications similaires hormis la vente au détail
sont compris dans le 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 à l'intérieur et autour de l'habitation. Cependant, elle ne tient en général pas compte:
– 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 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 destinés à être utilisés en plein air;
– aux appareils conçus 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 équipés d'une batterie prévue comme source d'alimentation de la fonction de réfrigération;
– aux appareils assemblés sur le site par l'installateur;
– aux appareils avec motocompresseurs à distance;
– aux motocompresseurs (IEC 60335-2-34);
– aux distributeurs commerciaux avec ou sans moyen de paiement (IEC 60335-2-75);
– aux appareils de réfrigération et fabriques de glace à usage commercial avec une unité de fluide frigorigène ou un motocompresseur incorporés ou à distance (IEC 60335-2-89);
– aux fabriques de crème glacée à usage professionnel (IEC 60335-2-118).

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
