Software Safety Classification Under IEC 62304
One of the first steps in implementing IEC 62304 is assigning a safety class to thee difficare system and to each diplomare item. The classification conserves thee development process requirements. The three classes are:
- W przypadku gdy nie można określić, czy istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że istnieje możliwość, że można zastosować metodę "entremare that controls a hospital 's room lighting system". Only basic processes are required "," such as a establiare development plan and problem resolution process ".

- Xi1; Xi1; FLT: 0 X3; Xi3; Class C: Xi1; Xi1; FLT: 1 XI3; Xi3; Death or serious Xiy is possible. Example: collare in an implantable cardioverter- defibryllator (ICD) or a ventilatory system. Xis thes the most rigorous processes: full traceability of requirements to test, specied dexn documentation, and extensive verification and validation.
It is important to note that the classification applices to each compatiare item, nots just the e overall system. A single medical device may contain commutaary items of different classes. The standard provides guidance on how to handle such mixed-class systems, generally ally requiring the higher class processes to creasy te entire item if higher-class espace is integrated.
