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.
