家用和类似用途电器.安全.第2-17部分:毯子、垫子、衣服和类似柔性加热器具的特殊要求

[中文适用范围]： 本部分IEC 60335涉及家用和类似用途的电热毯、电热垫、电热衣物及其他柔性加热器具的安全性，其额定电压不超过250V，包括直流供电设备和电池供电设备。本标准也适用于与器具配套提供的控制单元。 本标准还包括非家庭正常使用但可能对公众构成危险的器具，如美容院或寒冷环境中使用的器具。 本标准尽可能考虑了家庭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： - 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的情况下安全使用器具的人员（包括儿童）； - 儿童玩耍器具的情况。 注101：当儿童经过父母或监护人充分指导并被认为有能力安全使用器具时，可视为无需监督的适龄使用者。 注102：需注意以下情况： - 用于车辆、船舶或飞机的器具可能需要附加要求； - 许多国家的国家卫生部门、劳动保护部门等机构可能规定附加要求。 注103：本标准不适用于以下情况： - 特殊环境（如腐蚀性或爆炸性环境）中使用的器具； - 刚性床暖器（如金属或陶瓷材质）； - 水床加热器（IEC 60335-2-66）； - 动物养殖加热设备（IEC 60335-2-71）； - 足部取暖器和加热垫（IEC 60335-2-81）； - 医疗监护下使用的器具（IEC 60601-2-35）； - 电热地毯（IEC 60335-2-106）。 [外文原描述]： IEC 60335-2-17:2022 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 60335-2-17:2022 edition 4.0 and the previous IEC 60335-2-17:2012+AMD1:2015+AMD2:2019 CSV edition 3.2. Futhermore, comments from IEC TC 61 experts are provided to explain the reasons of the most relevant changes. IEC 60335-2-17:2022 deals with the safety of electric blankets, pads, clothing and other flexible appliances that heat the bed or human body, for household and similar purposes, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances. This standard also applies to control units supplied with the appliance. Appliances not intended for normal household use but which nevertheless possibly pose be a source of danger to the public, such as appliances intended to be used in beauty parlours or by persons in cold ambient temperatures, are within the scope of this standard. Requirements and tests for clothing are given in normative Annex CC. 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. Children are considered to be old enough to use an appliance without supervision when they have been adequately instructed by a parent or guardian and are deemed competent to use the appliance safely. 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 – 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); – rigid bed warmers, such as those of metal or ceramic material; – water bed heaters (IEC 60335-2-66); – heating appliances for breeding and rearing animals (IEC 60335-2-71); – foot warmers and heating mats (IEC 60335-2-81); – appliances specifically intended for use under medical supervision (IEC 60601-2-35); – heated carpets (IEC 60335-2-106). This fourth edition cancels and replaces the third edition published in 2012, Amendment 1:2015 and Amendment 2:2019. 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, 19.106, 21.103, 21.104, 21.110, 30.1, 30.102, Annex BB, CC.19.3); c) clarification of the definition of control unit (3.6.105); d) revision for adjusting the supply voltage of appliances, other than controlled appliances, when operation at rated power input times a factor is specified (5.12); e) clarification of testing of blankets that cannot be folded with five thicknesses (19.101); f) updated compliance criteria to include breakage of electrodes (21.1); g) clarification of the test method for mattresses based on the rigidity index of the flexible part (21.111.1, Annex DD); h) clarification for testing heating elements with a non-circular construction (21.111.3); i) addition of requirements to protect the user from overheating in the event of an interruption in the mains supply (22.110) j) inclusion of pressure test method from IEC 60320-1:2001 (30.1); k) update of test methods for resistance to fire tests (30.101.1, 30.102). 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.
