IEC 63044-5-2:20 17是一个产品系列标准，除了HBES/BACS设备的产品EMC标准之外，还为HBES/BACS网络设定了最低EMC性能水平。它还适用于HBES/BACS网络中使用的设备，这些设备不存在特定的HBES/BACS产品EMC标准。此外，它还定义了打算连接到HBES/BACS网络的设备接口的EMC要求。它不适用于到其他网络的接口。 注其他网络的一个例子是CISPR 22和23所涵盖的专用ICT网络。 根据IEC 61000-6-1中给出的定义，本文件规定了安装在住宅、商业和轻工业环境中的HBES/BAC的EMC要求。 本文件适用于（但不限于） 操作员站和其他人机界面设备， 用于管理功能的设备， 控制装置、自动化站和专用控制器， 现场设备及其接口， 设备的布线和互连， 在专用HBES/BACS网络中使用。本出版物应与IEC 63044-5-1:20 17一起阅读。

IEC 63044-5-2:2017 is a product family standard that sets the minimum level of EMC performance for the HBES/BACS network in addition to the product EMC standards for HBES/BACS devices. It also applies to devices used within an HBES/BACS network for which no specific HBES/BACS product EMC standard exists. In addition, it defines EMC requirements for the interface of equipment intended to be connected to an HBES/BACS network. It does not apply to interfaces to other networks.
NOTE An example of other networks is a dedicated ICT network covered by CISPR 22 and 23.
This document specifies EMC requirements for HBES/BACS to be installed in residential, commercial and light-industrial environments, according to the definition given in IEC 61000-6-1.
This document is applicable (but not limited) to

• operator stations and other human–system interface devices,
• devices for management functions,
• control devices, automation stations and application-specific controllers,
• field devices and their interfaces,
• cabling and interconnection of devices,

used within a dedicated HBES/BACS network. This publication is to be read in conjunction with IEC 63044-5-1:2017.
