家用和类似用途电器 安全 第 122 部分：商用洗衣机的特殊要求

[中文适用范围]： 本部分 IEC 60335 涉及电动商用洗衣机的安全性，其额定电压单相不超过250V，其他电器不超过480V。这些电器不适用于家庭和类似用途。它们由专家或受过培训的人员在不对公众开放的区域使用，例如农场、酒店、医院、餐厅和食堂；或由普通人员在向公众开放的区域使用，例如自助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。这些电器设计为连接到热水或冷水供应。利用蒸汽或热水进行加热的电器也在本标准的范围内。本标准尽可能处理这些类型电器带来的常见危险。然而，一般不考虑儿童玩耍电器的情况。需要注意的是：对于用于车辆、船舶或飞机上的电器，可能需要额外的要求；在许多国家，国家卫生当局、国家劳动保护当局、国家供水当局等可能规定额外要求；对于具有附加功能（例如干燥功能）的电器，其他标准也适用。本标准不适用于：专为工业用途设计的电器（ISO 10472-2）；用于特殊条件（如腐蚀性或爆炸性环境）的电器；家用和类似用途的洗衣机（IEC 60335-2-7）。 [外文原描述]： IEC 60335-2-122:2023 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with the comprehensive content of the Standard. IEC 60335-2-122:2023 EXV includes the content of the references made to IEC 60335-1:2020. 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.
