IEC 61156-6:20 20 RLV包含官方IEC国际标准及其红线版本。Redline版本不是官方文档，它只有英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61156-6:20 20描述了主要用于ISO/IEC 11801中定义的工作区域布线的电缆（所有部分）。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。这些电缆可用于同时使用多达四对的各种通信信道。从这个意义上说，本文档提供了系统开发人员评估新系统所需的电缆特性。本第四版取消并取代了2010年出版的第三版和修正案1:20 12。与上一版相比，它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 61156-6:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 61156-6:2020 describes the cables intended primarily for working area wiring as defined in ISO/IEC 11801 (all parts). 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. These cables can be used for various communication channels which use as many as four pairs simultaneously. In this sense, this document provides the cable characteristics required by system developers to evaluate new systems. This fourth edition cancels and replaces the third edition published in 2010 and Amendment 1:2012. It 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
