IEC 61156-5:20 20作为IEC 61156-5:20 20 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 61156-5:20 20描述了主要用于ISO/IEC 11801中定义的水平地板布线的电缆。它涵盖了包括单独屏蔽、普通屏蔽和非屏蔽对或四对电缆设计。电缆的传输特性和频率范围规定在20°C时。本文件所涵盖的电缆旨在以通信系统中通常遇到的电压和电流操作。这些电缆旨在用于支持低压远程供电应用的递送，例如IEEE 802.3 af(以太网供电)或例如根据IEEE 802的进一步发展。3at或IEEE 802.3 bt。本第三版取消并取代了2009年出版的第二版和修正案1:20 12。与上一版相比，此版本包括以下重大技术变更-通过某些布线规范相对于MICE实现的附加平衡水平；-参考有关测量技术和远程供电的现行标准和技术报告。
IEC 61156-5:2020 is available as IEC 61156-5:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61156-5:2020 describes the cables intended primarily for horizontal floor wiring as defined in ISO/IEC 11801. It covers cable designs comprising individually screened, common screened and unscreened pairs or quads. The transmission characteristics and the frequency range of the cables are specified at 20 °C. The cables covered by this document are intended to operate with voltages and currents normally encountered in communication systems Those cables are intended to be used to support the delivery of low voltage remote powering applications such as IEEE 802.3af (Power over Ethernet) or further developments for example according to IEEE 802.3at or IEEE 802.3bt. This third edition cancels and replaces the second edition published in 2009 and Amendment 1:2012. This edition includes the following significant technical changes with respect to the previous edition
- additional balance levels with respect to MICE implementation by certain cabling specifications;
- reference to current standards and technical reports with respect to measurement techniques and remote powering.
