This Standard 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 Standard does not apply to: equipment covered by IEC 62368-1; and interfaces to other networks. NOTE An example of other networks is a dedicated HBES/BACS network covered by EN 50491-3. This Standard specifies the safety requirements of the interface to the ICT network only. Requirements additional to those specified in this Standard 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 Standard: 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.
