IEC 61156-1:20 23作为IEC 61156-1:20 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 61156-1:20 23规定了定义、多芯对称对电缆和四芯电缆的要求和测试方法。本文件适用于局域网（LAN）和数据通信电缆等通信系统。它还适用于用于工业应用的电缆、客户场所布线和通用布线，包括ISO/IEC 11801（所有部分）中定义的安装电缆和用于工作区布线的电缆。本文件涵盖的电缆旨在在通信系统中通常遇到的电压和电流下工作。虽然这些电缆不打算与低阻抗源结合使用，例如公共事业干线的电力供应，但它们打算用于支持deli非常低电压远程供电应用，包括但不限于ISO/IEC/IEEE 8802-3中规定的以太网供电。

IEC 61156-1:2023 is available as IEC 61156-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61156-1:2023 specifies the definitions, requirements and test methods of multicore, symmetrical pair and quad cables. This document is applicable to communication systems such as local area networks (LANs) and data communication cables. It is also applicable to cables used for industrial applications, customer premises wiring and generic cabling comprising installation cables and cables for work area wiring which are defined in ISO/IEC 11801 (all parts). The cables covered by this document are intended to operate with voltages and currents normally encountered in communication systems. While these cables are not intended to be used in conjunction with low impedance sources, for example the electric power supplies of public utility mains, they are intended to be used to support the delivery of low voltage remote powering applications including but not restricted to Power over Ethernet as specified in ISO/IEC/IEEE 8802-3.
