家用及类似用途电器安全 第2-45部分：便携式加热工具及类似器具的特殊要求

[中文适用范围]： 本部分IEC 60335涉及便携式电加热工具和类似设备的安全性，其额定电压不超过250V，包括直流供电设备和电池供电设备。 不适用于普通家用但可能对公众构成危险的设备，如商店、轻工业和农场中非专业人员使用的设备，也在本标准的范围内。 也可以在使用时安装在支架上的设备也在本标准的范围内。 本标准的示例设备包括：烙印工具、燃烧笔、管道焊接工具、去角工具、脱焊烙铁、消防员、胶枪、热风枪、家用薄膜焊接设备、油漆剥离器、塑料切割工具、焊枪、焊铁、剥线钳、热塑性管道焊接工具。 本标准尽可能处理了家庭及其周围环境中所有人员遇到的设备常见危险。然而，一般来说，本标准不考虑以下情况：身体、感官或精神能力不足或缺乏经验和知识的人（包括儿童）无法在没有监督或指导的情况下安全使用设备；儿童玩耍设备。 本标准不适用于：手持电动工具（IEC 60745系列，IEC 62841系列）；便携式电动工具（IEC 61029系列，IEC 62841系列）；专为工业用途设计的设备；在特殊条件下使用的设备，如存在腐蚀性或爆炸性环境（粉尘、蒸汽或气体）；除感应焊铁外使用高频加热的工具；弧焊设备。 [外文原描述]： IEC 60335-2-45:2024 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 a comprehensive content of the Standard. IEC 60335-2-45:2024 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-45:2024 deals with the safety of portable electric heating tools and similar appliances, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances. Appliances not intended for normal household use, but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laypersons in shops, in light industry and on farms, are within the scope of this standard. Appliances that can also be used when mounted on a support are within the scope of this standard. Examples of appliances that are within the scope of this standard are – branding tools; – burning-in pens; – conduit-soldering tools; – dehorning tools; – desoldering irons; – firelighters; – glue guns; – heat guns; – household film-welding appliances; – paint strippers; – plastic-cutting tools; – soldering guns; – soldering irons; – stripping pliers; – thermoplastic conduit-welding tools. As far as is practicable, this standard deals with the common hazards presented by appliances which are encountered by all persons in and around the home. However, in general, it does not in general 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 – hand-held motor-operated electric tools (IEC 60745 series, IEC 62841 series); – transportable motor-operated electric tools (IEC 61029 series, IEC 62841 series); – appliances intended 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); – tools using high-frequency heating other than induction soldering irons; – arc-welding equipment. This fourth edition cancels and replaces the third edition published in 2002, Amendment 1:2008 and Amendment 2:2011. 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) deletion or conversion of some notes to normative text (Clause 1, 5.2, 15.101, 22.105, 25.7); c) introduction of external accessible surfaces temperature limits, including addition of functional surface and hot surface requirements (3.6.101, 7.1, 7.6, 7.12, 7.14, 7.15, 11.3, 11.8); 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.
