IEC 61069-6:2016 specifies the detailed method of the assessment of operability of basic control system (BCS), based on the basic concepts of IEC 61069-1 and methodology of IEC 61069-2; defines basic categorization of operability properties; describes the factors that influence operability and which need to be taken into account when evaluating operability; provides guidance in selecting techniques from a set of options (with references) for evaluating the operability. This second edition cancels and replaces the first edition published in 1998. 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 61069-6:1998 to make the overall set of standards more organized and consistent;- IEC TS 62603-1 has been incorporated into this edition.
