scope:

IEC&nbsp;63044-5-3:2017 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 industrial environments, according to the definition given in IEC&nbsp;61000-6-2. NOTE - Industrial environment covers the office spaces that may be present in industrial premises. Industrial automation systems are outside the scope. This document is applicable (but not limited) to <ul> <li> operator stations and other human&ndash;system interface devices,</li> <li> devices for management functions,</li> <li> control devices, automation stations and application-specific controllers,</li> <li> field devices and their interfaces,</li> <li> cabling and interconnection of devices,</li> </ul> used within a dedicated HBES/BACS network.
