IEC 62026-1:20 19 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 62026-1:20 19适用于低压开关设备、控制设备和控制器（如可编程控制器、个人计算机等）之间的接口。）.本文件不适用于已被称为现场总线并由IEC小组委员会65C考虑的更高级别的工业通信网络。这第三版取消并取代了2007年出版的第二版。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)对安全信息和说明的附加要求，包括为实现EMC合规性而采取的措施（如有）； b)EMC抗扰度要求与当前IEC 61000-6系列标准一致。辐射射频电磁场测试水平提高到6 GHz； c)EMC排放要求与当前CISPR 11出版物一致。

IEC 62026-1:2019 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 62026-1:2019 applies to interfaces between low-voltage switchgear, controlgear, and controllers (e.g. programmable controllers, personal computers, etc.). This document does not apply to higher level industrial communication networks that have become known as fieldbuses and are considered by IEC subcommittee 65C. This third edition cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) additional requirements for safety information and instructions, including the measures to be taken, if any, for achieving EMC compliance;
b) EMC immunity requirements aligned with current IEC 61000-6 series of standards. Radiated radio-frequency electromagnetic fields test level increased to 6 GHz;
c) EMC emissions requirements aligned with current CISPR 11 publication.
