IEC 60335-2-96:2024 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 60335-2-96:2024版3.0和之前的IEC 60335-2-96:2019版2.0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，或澄清内容的任何部分。 IEC 60335-2-96:2024涉及打算安装在1.2 m以下和2.3 m以上的地板和墙壁以及天花板中的柔性片状加热元件的安全性，其额定电压对于单相安装不超过250 V，对于包括直流（DC）供电设备在内的其他安装不超过480 V。根据说明书，柔性片加热元件被转换成加热单元，这些加热单元被结合到建筑物中，之后达到所需的危险防护水平。提请注意以下事实: -在许多国家，适用不同的接线规则； -对于打算用于车辆或船上或飞机的加热装置，可能需要额外的要求； -在许多国家，国家消防当局、国家建筑条例当局、国家卫生当局、国家劳动保护当局和类似当局规定了额外的要求。 本标准不适用于 -专门用于工业目的的加热装置； -打算在有特殊条件的地方使用的加热装置，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）； -毯子、垫子、衣服和类似的柔性加热器具（IEC 60335-2-17); -暖脚器和加热垫(IEC 60335-2-81)； -加热地毯和安装在可拆卸地板覆盖物下的用于房间加热的加热单元（IEC 60335-2-106）； -结合在其他器具中的柔性片加热元件。 这第三版取消并取代了2019年出版的第二版。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、5.2、7.12.101条）； c)修正以恢复22.105中的触摸电流限制。 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 60335-2-96:2024 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 60335-2-96:2024 edition 3.0 and the previous IEC 60335-2-96:2019 edition 2.0. 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 60335-2-96:2024 deals with the safety of flexible sheet heating elements intended to be incorporated into floors and walls below 1,2 m and above 2,3 m and in ceilings, their rated voltage being not more than 250 V for single-phase installations and 480 V for other installations including direct current (DC) supplied appliances. Flexible sheet heating elements are converted into heating units that are incorporated in the building in accordance with the instructions after which the required level of protection against hazards is achieved.
Attention is drawn to the fact that
- in many countries, different wiring rules apply;
- for heating units 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 authorities for fire protection, the national authorities for building regulations, the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to
- heating units intended exclusively for industrial purposes;
- heating units intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
- blankets, pads, clothing and similar flexible heating appliances (IEC 60335-2-17);
- foot warmers and heating mats (IEC 60335-2-81);
- heated carpets and for heating units for room heating installed under removable floor coverings (IEC 60335-2-106);
- flexible sheet heating elements incorporated in other appliances.
This third edition cancels and replaces the second edition published in 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, 5.2, 7.12.101);
c) correction to reinstate the touch current limit in 22.105.
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.
