This part of IEC 61069 :
-
specifies the detailed method of the assessment of dependability of a basic control system (BCS) based on the basic concepts of IEC 61069‑1 and methodology of IEC 61069‑2 ,
-
defines basic categorization of dependability properties,
-
describes the factors that influence dependability and which need to be taken into account when evaluating dependability, and
-
provides guidance in selecting techniques from a set of options (with references) for evaluating the dependability.
