IEC 61069-4:2016 specifies the detailed method of the assessment of performance 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 performance properties, describes the factors that influence performance and which need to be taken into account when evaluating performance, and provides guidance in selecting techniques from a set of options (with references) for evaluating the performance. This second edition cancels and replaces the first edition published in 1997. 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 61069-4:1997 to make the overall set of standards more organized and consistent; – IEC TS 62603-1:2014 has been incorporated into this edition.
