IEC 60335-2-122:2023涉及电动商用洗衣机的安全性，单相额定电压不超过250 V，其他电器额定电压不超过480 V。 这些电器不用于家用和类似用途。它们用于: -在农场、旅馆、医院、餐馆和食堂等不对公众开放的地方，由专家或受过培训的人进行商业清洗；或 -由门外汉在向公众开放的地方，例如洗衣店和公共洗衣房。 利用其他形式能量的电器的电气部分也在本标准的范围内。 这些设备被设计成连接到热水或冷水供应。 利用蒸汽或热水加热的器具也在本标准的范围内。在可行的情况下，本标准涉及这些类型的器具带来的常见危害。然而，一般来说，它不考虑幼儿玩该设备。 提请注意以下事实: -对于拟用于车辆或船舶或飞机上的器具，可能需要附加要求； -在许多国家，国家卫生当局、负责保护劳工的国家当局、国家供水当局和类似当局规定了额外的要求； -在许多国家，对包含加压部件的器具规定了附加要求； -对于具有附加功能(例如干燥功能)的器具，其他标准也适用。 本标准不适用于:-专为工业用途设计的器具（ISO 10472-2）； -拟在有特殊条件的地方使用的器具，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）； -家用和类似用途的洗衣机器具（IEC 60335-2-7）。 本第2部分应与最新版本的IEC 60335-1及其修订一起使用，除非该版本排除了本第2部分；在这种情况下，使用不排除它的最新版本。它是在该标准第六版（2020年）的基础上建立的。

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.
