– opremo, obravnavano v standardu IEC 62368-1; in
– vmesnike za druga omrežja.
OPOMBA 1: Primer »drugih omrežij« je namensko omrežje stanovanjskih in stavbnih elektronskih sistemov/sistemov za avtomatizacijo in krmiljenje stavb HBES/BACS, ki je zajeto v standardu EN 50491-3.
Ta dokument določa varnostne zahteve za vmesnik samo za omrežje ICT.
OPOMBA 2: Glej dodatek D.
Dodatne zahteve, ki veljajo poleg zahtev, določenih v tem dokumentu, bodo morda potrebne za:
• opremo, namenjeno za uporabo, ko je na primer izpostavljena ekstremnim temperaturam, prekomernemu prahu, vlažnosti ali vibracijam, vnetljivim plinom, korozivnim ali eksplozivnim atmosferam;
• elektromedicinsko opremo, ki je fizično priključena na bolnika.
Ta dokument ne zajema naslednjih zahtev:
• funkcionalna varnost opreme;
• funkcionalna zanesljivost opreme;
• komunikacijske naprave z oddaljenim napajanjem z nevarno napetostjo;
• zaščita opreme, priključene na omrežja ICT, pred funkcijskimi poškodbami.
