IEC 60335-2-122:2023

Household and similar electrical appliances - Safety - Part 2-122: Particular requirements for commercial washing machines

IEC 60335-2-122:2023 deals with the safety of electrically operated commercial washing machines, their rated voltage being not more than 250 V for single phase and 480 V for other appliances.
These appliances are not intended for household and similar purpose. They are used:
- by experts or instructed persons for commercial washing in areas not open to the public, for example on farms and in hotels, hospitals, restaurants and canteens; or
- by laymen in areas open to the public, for example launderettes and communal laundry rooms.
The electrical part of appliances making use of other forms of energy is also within the scope of this standard.
These appliances are designed to be connected to hot or cold water supply.
Appliances making use of steam or hot water for heating purposes are 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. However, in general, it does not consider young 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 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 appliances incorporating pressurized parts;
- for appliances having additional functions (e.g. drying function), other standards are also applicable.
This standard does not apply to:
- appliances designed exclusively for industrial purposes (ISO 10472-2);
- 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);
- washing machines appliances for household and similar use (IEC 60335-2-7).
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 2-122: Exigences particulières pour les machines à laver le linge à usage commercial

L'IEC 60335-2-122:2023 traite de la sécurité des machines à laver le linge électriques à usage commercial, dont la tension assignée est inférieure ou égale à 250 V pour les appareils monophasés et à 480 V pour les autres appareils.
Ces appareils ne sont pas destinés à un usage domestique ou analogue. Ils sont utilisés:
- par des experts ou des personnes formées pour le lavage commercial du linge dans des lieux non ouverts au public, par exemple dans des fermes ou des hôtels, des hôpitaux, des restaurants et des cantines; ou
- par des personnes non averties dans des lieux ouverts au public, par exemple dans des laveries automatiques et des buanderies mises à la disposition commune des usagers.
La partie électrique des appareils qui utilise d'autres formes d'énergie est également comprise dans le domaine d'application de la présente norme.
Ces appareils sont destinés à être raccordés à une alimentation en eau chaude et/ou froide.
Les appareils qui utilisent de la vapeur ou de l'eau chaude pour le chauffage relèvent également du 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. Toutefois, en général, elle ne couvre pas les jeunes enfants qui jouent avec l'appareil.
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 qui comportent des parties sous pression;
- pour les appareils qui disposent de fonctions supplémentaires (fonction de séchage, par exemple), d'autres normes sont également applicables.
La présente norme ne s'applique pas:
- aux appareils prévus exclusivement pour des usages industriels (ISO 10472-2);
- 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 machines à laver le linge à usage domestique et analogue (IEC 60335-2-7).
La présente partie 2 doit être utilisée conjointement avec la dernière édition de l'IEC 60335-1 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.

INTRODUCTION
Edition 6 of IEC 60335-1:2020 defines and introduces requirements for a detachable
power supply part of an appliance. In the document, 24.2 prohibits the use of a power
supply in a flexible cord.
QUESTION:
Does Subclause 24.2 prohibit the use of a detachable power supply part?
ANSWER
No, a "detachable power supply part" is a defined term and is not captured by the term
"power supply" as used in Subclause 24.2.
NOTE A detachable power supply part is captured by the defined term when the output of the power supply
part is detachable from the class III construction part of the appliance at:
– the power supply part, or
– the class III construction part of the appliance.
However, the supply cord (if any) does not have to be detachable from the detachable power supply part.

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 publi
