IEC 61069-5:2016 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. This second edition cancels and replaces the first edition published in 1994. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- reorganization of the material of IEC 61069-5:1994 to make the overall set of standards more organized and consistent;
- IEC TS 62603-1 has been incorporated into this edition.
