IEC 61535:2019 is available as IEC 61535:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61535:2019 applies to two-wire, up to five-wire installation couplers, including earth, if provided, with a rated voltage up to and including 500 V AC or DC and a rated connecting capacity up to and including 10 mm2 for permanent connection in electrical installations. Installation couplers with additional contacts for voltages other than mains voltages are outside the scope of this document. This second edition cancels and replaces the first edition published in 2009 and Amendment 1:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - enlargement of the scope to DC application; - addition of further requirements as regards DC application (marking, etc.), no additional test procedures were deemed necessary; however some modifications were necessary in the normative text; - changes and enhancement of the field of application of installation couplers into outdoor applications; - addition of a suitable temperature range; - updating of the list of normative references, modified to undated references, where possible.

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.
