IEC 60335-2-17:20 22 CMV包含官方标准及其注释版本。注释版本为您提供了一种快速简单的方法来比较IEC 60335-2-17:20 22版4.0和之前的IEC 60335-2-17:20 2+AMD1:2015+AMD2:2019 CSV版3.2之间的所有更改。此外，还提供了IEC TC 61专家的意见，以解释最相关变更的原因。 IEC 60335-2-17:20 22涉及家用和类似用途的电热毯、垫、衣服和其他加热床或人体的柔性电器的安全性，其额定电压不超过250 V，包括直流（DC）供电的电器和电池供电的电器。 本标准也适用于设备随附的控制单元。 不打算供正常家庭使用但可能对公众构成危险的电器，例如打算在美容院或供人在寒冷环境温度下使用的电器ures，均在本标准的范围内。 服装的要求和测试在规范性附录CC中给出。 在可行的情况下，本标准涉及家庭内外所有人都会遇到的电器带来的常见危险。然而，一般来说，它没有考虑到 -身体、感官或精神能力或缺乏经验和知识使他们无法在没有监督或指导的情况下安全使用器具的人（包括儿童）； -儿童在玩电器。 当儿童已经得到父母或监护人的充分指导，并被认为有能力安全使用该设备时，他们被认为已经足够大，可以在没有监督的情况下使用该设备。 提请注意以下事实: -对于拟用于车辆或船舶或飞机上的器具，可能需要附加要求；-在许多国家，国家卫生当局、负责保护劳工的国家当局和类似当局规定了额外的要求。 本标准不适用于 -拟在有特殊条件的地方使用的器具，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）； -刚性床暖器，例如金属或陶瓷材料的那些； -水床加热器(IEC 60335-2-66)； -用于繁殖和饲养动物的加热器具（IEC 60335-2-71）； -暖脚器和加热垫(IEC 60335-2-81)； -专门用于医疗监督的器械（IEC 60601-2-35）； -加热地毯(IEC 60335-2-106)。 本第四版取消并取代2012年出版的第三版，修正案1:2015和修正案2:20 19。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)符合IEC 60335-1:20 20； b)将一些注释转换为规范性文本（第1条、19.106、21.103、21.104、21.110、30.1、30.102、附件BB、CC.19.3）； c)澄清控制单元的定义(3.6.105)； d)当在额定功率输入下运行时，用于调整除受控电器以外的电器的电源电压的修订(5.12)； e)澄清不能折叠成五种厚度的毯子的测试(19.101)； f)更新符合性标准以包括电极破损(21.1)； g)基于柔性部分刚性指数的床垫测试方法的澄清(21.111.1，附件DD)； h)测试具有非圆形结构的加热元件的说明(21.111.3)； i)增加了在主电源中断时保护用户免受过热的要求(22.110) j)包括来自IEC 60320-1:20 01(30.1)的压力测试方法； k)更新耐火试验的试验方法（30.101.1、30.102）。 本第2部分应与最新版本的IEC 60335-1及其修订一起使用，除非该版本排除了本第2部分；在这种情况下，使用不排除它的最新版本。它是在该标准第六版（2020年）的基础上建立的。

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.
