IEC 60335-2-97:2023 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 60335-2-97:2023版4.0和之前的IEC 60335-2-97:2016+AMD1:2019 CSV版3.1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 60335-2-97:2023涉及家用和类似用途的百叶窗、百叶窗和遮阳篷的电力驱动器的安全性，单相驱动器的额定电压不超过250 V，其他驱动器的额定电压不超过480 V，包括直流(DC)供电的电器和电池供电的电器。 可以驱动的设备的例子有 -弹簧控制的折叠臂遮阳篷；-窗帘； -覆盖门窗的格栅； -投影屏幕； -覆盖门窗的百叶窗； -窗帘。 驱动器可以与从动部件一起提供。 不打算用于正常家庭使用但可能对公众造成危险的驱动器，例如打算供商店、轻工业、农场和工业场所的非专业人员使用的驱动器，都在本标准的范围内。 在可行的情况下，本标准涉及家中和周围所有人都会遇到的驱动器带来的常见危险。然而，一般来说，它没有考虑到 -身体、感官或精神能力受损的人（包括儿童）；或者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地使用驱动器；-孩子们在玩驱动器。 对于打算用于车辆或船舶或飞机上的设备，可能需要额外的要求。在许多国家，国家卫生当局、负责劳动保护的国家当局、国家供水当局和类似当局规定了额外的要求。 本标准不适用于 -打算在特殊条件占优势的地方使用的驱动器，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）； -住宅用垂直移动车库门的驱动器(IEC 60335-2-95)； -用于大门、门和窗的驱动器(IEC 60335-2-103)； -用于机库或重工业等场所的驱动器； -剧院窗帘的驱动器。本第四版取消并取代了2016年出版的第三版和修正案1:20 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)文本已与IEC 60335-1:20 20保持一致； b)范围包括直流供电的电器和电池供电的电器（条款1）； c)一些注释已转换为规范性文本（第1、5.10、20.101、20.103条）； d)介绍了人工负载的使用(5.10)； e)已经介绍了测试探针19的应用(8.1.1、20.2)； f)增加外部可接近表面(11.3、11.8)的表面温度； g)增加了与连接器一起交付的用于永久连接的驱动器的要求，以简化安装(22.102,24.1.101,25.3); h)接合后不可拆卸的连接器的说明（24.1.5）。 i)增加了由可拆卸电源部件提供的III类结构部件的说明要求（7.12、7.12.1）。 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 60335-2-97:2023 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 60335-2-97:2023 edition 4.0 and the previous IEC 60335-2-97:2016+AMD1:2019 CSV edition 3.1. 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 60335-2-97:2023 deals with the safety of electric drives for shutters, blinds and awnings, intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase drives and 480 V for other drives, including direct current (DC) supplied appliances and battery-operated appliances.
Examples of equipment that can be driven are
– spring controlled folding arm awnings;
– curtains;
– grilles covering doors and windows;
– projection screens;
– shutters covering doors and windows;
– draperies.
Drives can be supplied with a driven part.
Drives not intended for normal household use but that nevertheless can be a source of danger to the public, such as drives intended to be used by laymen in shops, in light industry, on farms and on industrial premises, are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by drives 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 drive safely without supervision or instruction;
– children playing with the drive.
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, the national water supply authorities and similar authorities.
This standard does not apply to
– drives intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– drives for vertically moving garage doors for residential use (IEC 60335-2-95);
– drives for gates, doors and windows (IEC 60335-2-103);
– drives used in premises such as hangars or in heavy industry;
– drives for theatre curtains.
This fourth edition cancels and replaces the third edition published in 2016 and Amendment 1: 2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the text has been aligned with IEC 60335-1:2020;
b) scope includes DC-supplied appliances and battery-operated appliances (Clause 1);
c) some notes have been converted to normative text (Clause 1, 5.10, 20.101, 20.103);
d) use of artificial loads is introduced (5.10);
e) application of test probe 19 has been introduced (8.1.1, 20.2);
f) addition of surface temperatures for external accessible surfaces (11.3, 11.8);
g) requirements are added for drives intended for permanent connection delivered with a connector to ease the installation (22.102, 24.1.101, 25.3);
h) clarification for connectors that are non-detachable once engaged (24.1.5).
i) added requirements for instructions for parts of class III construction supplied from a detachable power supply part (7.12, 7.12.1).
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.
