标准摘要
[中文适用范围]： IEC 61069:?C的本部分规定了基于IEC 61069-1的基本概念和IEC 61069-2@的方法论的基本控制系统(BCS)可靠性评估的详细方法。?C定义了可靠性的基本分类属性@ ?C 描述了影响可靠性的因素以及评估可靠性时需要考虑的因素@ 和?C 提供了从一组选项（带有参考）中选择技术来评估可靠性的指导。 [外文原描述]： 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.
