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.
