IEC 60728-11:20 23作为IEC 60728-11:20 23 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。 IEC 60728-11:20 23涉及适用于固定场所系统和设备的安全要求。只要适用，它也适用于移动和临时安装的系统，例如大篷车。可以应用附加要求，例如，参考以下内容: -建筑物和架空线路的电气装置， -其他电信服务分配系统， -配水系统， -气体分配系统， -闪电系统。 本文件旨在提供专门针对系统、系统工作人员、用户和用户设备安全的要求。它仅涉及安全方面，并不旨在定义系统中使用的设备的保护标准。IEC 60728-11:20 23取消并取代了2016年发布的第四版。本版构成技术修订版。与上一版相比，该版本包括以下重大技术变化。 a)将IEC 60065和IEC 60950-1替换为IEC 62368-1。 b)增加第4.4至4.6款。 c)I类设备、II类设备、主接地端子的修订定义见3.1.6、3.1.8和3.1.31。 d)增加危害、危害、普通人、受指导人员、技术人员的定义，见3.1.22、3.1.23、3.1.39、3.1.40和3.1.41。 e)提供所安装设备详细信息的附加要求，参见4。1. f)附加机械、设计和施工要求，见4.2.2。 g)可接近部件要求的变更，参见4.2.3。 h)元件的载流能力和介电强度现在是强制性的，见8.1.3。 i)雷击风险评估现在是强制性的，见图10。 j)用户馈线上远程馈线电压的延伸，见表1。

IEC 60728-11:2023 is available as IEC 60728-11:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60728-11:2023 deals with the safety requirements applicable to fixed sited systems and equipment. As far as applicable, it is also valid for mobile and temporarily installed systems, for example, caravans. Additional requirements may be applied, for example, referring to:
- electrical installations of buildings and overhead lines,
- other telecommunication services distribution systems,
- water distribution systems,
- gas distribution systems,
- lightning systems.
This document is intended to provide requirements specifically for the safety of the system, personnel working on it, subscribers and subscriber equipment. It deals only with safety aspects and is not intended to define a standard for the protection of the equipment used in the system. IEC 60728-11:2023 cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition.
a) Replacement of references to IEC 60065 and IEC 60950-1 with references to IEC 62368-1.
b) Addition of subclauses 4.4 to 4.6.
c) Revised definition of class I equipment, class II equipment, main earthing terminal, see 3.1.6, 3.1.8 and 3.1.31.
d) Addition of definitions for harm, hazard, ordinary person, instructed person, skilled person, see 3.1.22, 3.1.23, 3.1.39, 3.1.40 and 3.1.41.
e) Additional requirement to provide details on the equipment installed, see 4.1.
f) Additional mechanical, design and construction requirements, see 4.2.2.
g) Changes to the accessible part requirements, see 4.2.3.
h) The current carrying capacity and dielectric strength of components is now obligatory, see 8.1.3.
i) The assessment of the risk of lightning strike is now obligatory, see Figure 10.
j) Extension of remote feeding voltage on subscriber feeder, see Table 1.
