工业过程测量和控制 - 系统评估用系统性能评估 - 第4部分:系统性能评估

[中文适用范围]： 本部分 IEC 61069： - 基于 IEC 61069-1 的基本概念和 IEC 61069-2 的方法论，规定了基本控制系统（BCS）性能评估的详细方法， - 定义了性能属性的基本分类， - 描述了影响性能的因素，这些因素在评估性能时需要被考虑， - 提供了从一组选项中选择技术（附有参考）以评估性能的指导。 [外文原描述]： 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.
