Pertains to the interface of equipment designed and intended to be connected as a communication terminal to an information and communication technology (ICT) network termination.

This document applies to the interface of equipment designed and intended to be connected as a communication terminal to an information and communication technology (ICT) network termination. This document does not apply to: equipment covered by IEC62368‑1 ; and interfaces to other networks. NOTE1 An example of ‘other networks’ is a dedicated Home and Building Electronic Systems/Building Automation and Control Systems HBES/BACS network covered by EN50491‑3 . This document specifies the safety requirements of the interface to the ICT network only. NOTE2 See AnnexD. Requirements additional to those specified in this document may be necessary for equipment intended for operation while exposed, for example, to extremes of temperature, to excessive dust, moisture, or vibration, to flammable gases, to corrosive or explosive atmospheres, electro medical applications with physical connections to the patient. The following requirements are not covered by this document: functional safety of equipment; functional reliability of equipment; communication facilities with remote supply using hazardous voltage; protection of equipment connected to ICT networks from functional damage.
