家用及类似用途电器 安全 第2-81部分：暖脚器和加热垫的特殊要求

[中文适用范围]： 本部分IEC 60335涉及家用和类似用途的电暖足器和加热垫的安全，其额定电压不超过250V，包括直流供电设备和电池供电设备。 非家用但可能对公众造成危险的设备，如供非专业人员在商店、轻工业和农场使用的设备，也在本标准范围内。 本标准尽可能处理家用电器对家庭内外所有人造成的常见危险。但通常不考虑以下情况： - 因身体、感官或精神能力不足，或缺乏经验和知识而无法在无人监督或指导情况下安全使用设备的人员（包括儿童）； - 儿童玩耍设备。 用于车辆、船舶或飞机的设备可能需要额外要求。许多国家还规定了国家卫生部门、劳动保护部门、国家供水部门等的额外要求。 本标准不适用于： - 专门用于医疗监护的设备； - 电热毯和电热垫（IEC 60335-2-17）； - 电热地毯（IEC 60335-2-106）； - 用于动物饲养的电加热设备（IEC 60335-2-71）。 [外文原描述]： IEC 60335-2-81:2024 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 60335-2-81:2024 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-81:2024 deals with the safety of electric foot warmers and heating mats for household and similar purposes, 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. 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. Additional requirements can be necessary for appliances intended to be used in vehicles or on board ships or aircraft. 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. This standard does not apply to: – appliances specifically intended for use under medical supervision; – electric blankets and pads (IEC 60335-2-17); – electrically heated carpets (IEC 60335-2-106); – electrical heating appliances for breeding and rearing animals (IEC 60335-2-71). This fourth edition cancels and replaces the third edition published in 2015, Amendment 1:2017 and Amendment 2:2020. 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) conversion of some notes to normative text (Clause 1, 13.2, 16.2, 21.103, 21.104, 21.105, 21.106); c) addition of test probe 19 for accessibility (8.1.1, 8.1.3, 20.2, B.22.3, B.22.4); d) addition of external surface temperatures (Clause 11); e) addition of the test of 21.107 for control units intended to be placed on a surface; f) alignment of 30.102 with IEC 60335-2-17. 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.
