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器具的安全，其额定电压不超过 250 V，包括直流供电设备和电池供电设备。不适用于正常家用的设备，但仍可能对公众造成危险的设备，如供外行人在商店、轻工业和农场使用的设备，也在本标准范围内。可以安装在支撑物上使用的设备也在本标准范围内。本标准尽可能处理家用及周围环境中所有人可能遇到的常见危险。但通常不考虑以下情况：身体、感官或智力能力不足或缺乏经验和知识而无法安全使用设备的人（包括儿童）以及儿童玩耍设备的情况。 [外文原描述]： IEC 60335-2-45:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60335-2-45:2024 edition 4.0 and the previous IEC 60335-2-45:2002+AMD1:2008+AMD2:2011 CSV edition 3.2. Furthermore, comments from IEC TC 61 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. 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.
