家用和类似用途电器安全第2-109部分：紫外线辐射水处理器具的特殊要求

[中文适用范围]： 本部分IEC 60335涉及家用和类似用途的紫外线辐射水处理设备的安全，其额定电压不超过单相设备250V和其他设备480V，包括直流供电设备和电池供电设备。 不用于正常家用但可能对公众造成危险的设备，如商店、轻工业和农场中由非专业人员使用的设备，也在本标准范围内。 本标准尽可能处理由设备引起的常见危险，这些危险可能由家庭内外所有人遇到。然而，通常不考虑以下情况： - 由于身体、感官或精神能力不足，或缺乏经验和知识而无法在没有监督或指导的情况下安全使用设备的人员（包括儿童）； - 儿童玩耍设备。 注意： - 用于车辆、船舶或飞机上的设备可能需要附加要求； - 在许多国家，国家卫生当局、国家劳动保护当局和类似当局规定了附加要求。 本标准不适用于： - 泵（IEC 60335-2-41）； - 水族箱灯具（IEC 60598-2-11）； - 游泳池和类似应用的灯具（IEC 60598-2-18）； - 专门用于专业用途的设备； - 用于特殊条件场所的设备，如存在腐蚀性或爆炸性环境（粉尘、蒸汽或气体）。 [外文原描述]： IEC 60335-2-109:2023 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 60335-2-109:2023 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-109:2023 deals with the safety of UV radiation water treatment appliances for household and similar use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances. Appliances not intended for normal household use but that nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops and in light industry and farms, 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 the national health authorities, the national authorities responsible for the protection of labour and similar authorities. This standard does not apply to - pumps (IEC 60335-2-41); - luminaires for aquariums (IEC 60598-2-11); - luminaires for swimming pools and similar applications (IEC 60598-2-18); - appliances intended exclusively for professional use; - 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). This second edition cancels and replaces the first edition published in 2010, Amendment 1:2013 and Amendment 2:2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with IEC 60335-1:2020; b) modification or conversion of some notes to normative text (Clause 1, 6.2, 22.102); c) introduction of IEC 60417 symbol for maximum operating depth (7.1, 7.6, 7.12.1); d) addition of external accessible surface temperature limits (11.3, 11.8); e) clarification of requirements for remote operation (22.40, 22.49, 22.51); f) the requirements to emit harmful radiation are deleted, because they are covered in Part 1 (Clause 32). 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.
