(Main)Household and similar electrical appliances - Safety - Part 2-47: Particular requirements for commercial electric boiling pans
Household and similar electrical appliances - Safety - Part 2-47: Particular requirements for commercial electric boiling pans
IEC 60335-2-47:2021 deals with the safety of electrically operated commercial boiling pans, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances. These appliances are not intended for household and similar purposes. They are used for commercial processing of food in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries. The electrical part of appliances making use of other forms of energy is also within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by these types of appliances.
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 the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities;
– in many countries additional requirements are specified for pressure appliances.
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);
– appliances for continuous mass production of food;
– battery-operated appliances.
This fifth edition cancels and replaces the fourth edition published in 2002, Amendment 1:2008 and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the text has been aligned with IEC 60335-1:2020;
b) some notes have been converted to normative text, modified or deleted (Clause 1, 7.15, 11.7, 9.101, 10.1, 11.4, 11.7, 19.101, 20.1, 22.101, 22.113, 23.3, 27.2);
c) clarifications to some test specifications have been made (15.1.1, 15.2, 20.1, 22.101, 22.102);
d) exclusion of battery-operated appliances and appliances used in areas open to the public (Clause 1);
This Part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-47: Exigences particulières pour les marmites électriques à usage commercial
L'IEC 60335-2-47:2021 traite de la sécurité des marmites électriques à usage commercial, dont la tension assignée est inférieure ou égale à 250 V pour les appareils monophasés raccordés entre un conducteur de phase et le conducteur de neutre, et à 480 V pour les autres appareils. Ces appareils ne sont pas destinés à un usage domestique ou analogue. Ils sont destinés à un usage commercial pour le traitement des aliments dans des lieux non ouverts au public, par exemple dans les cuisines de restaurants, les cantines, les hôpitaux et les entreprises commerciales, telles que les boulangeries et les boucheries. La partie électrique des appareils qui utilisent d'autres formes d'énergie est également comprise dans le domaine d'application de la présente norme. Dans la mesure du possible, la présente norme traite des dangers courants que présentent ces types d'appareils.
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;
– dans de nombreux pays, des exigences supplémentaires sont spécifiées pour les appareils sous pression.
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);
– aux appareils conçus pour la production continue en masse d'aliments;
– aux appareils alimentés par batteries.
Cette cinquième édition annule et remplace la quatrième édition parue en 2002, l'Amendement 1:2008 et l'Amendement 2:2017. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) alignement du texte sur l'IEC 60335-1:2020;
b) conversion en texte normatif, modification ou suppression de certaines notes (Article 1, 7.15, 11.7, 9.101, 10.1, 11.4, 11.7, 19.101, 20.1, 22.101, 22.113, 23.3, 27.2);
c) clarification de certaines modalités d'essais (15.1.1, 15.2, 20.1, 22.101, 22.102);
d) exclusion des appareils alimentés par batteries et des appareils utilisés dans des lieux ouverts au public (Article 1);
e) déplacement des instructions pour le nettoyage du 7.12.1 au 7.12;
f) introduction du 22.120;
g) alignement du texte de l'IEC 60335-2-47 sur les autres normes sous l'IEC/TC61/MT32.

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
