IEC 61511-3:20 16可作为IEC 61511-3:20 16获得包含国际标准及其红线的RLV版本，显示技术内容与上一版。当使用一个或多个SIF来保护人员、公众或环境来实现功能安全时，IEC 61511-3:20 16适用；可应用于资产保护等非安全应用；说明了可用于定义每个SIF的安全功能要求和SIL的典型危害和风险评估方法；示出了可用于确定所需SIL的技术/措施；提供了建立SIL的框架，但没有指定特定应用所需的SIL；没有举例说明确定其他降低风险方法的要求。这第二版取消并取代了2003年出版的第一版。本版构成技术修订版。与上一版相比，本版包括以下重大技术变更:提供了额外的H&RA示例和定量分析考虑附件。
IEC 61511-3:2016 is available as
IEC 61511-3:2016 applies when functional safety is achieved using one or more SIF for the protection of either personnel, the general public, or the environment; may be applied in non-safety applications such as asset protection; illustrates typical hazard and risk assessment methods that may be carried out to define the safety functional requirements and SIL of each SIF; illustrates techniques/measures available for determining the required SIL; provides a framework for establishing SIL but does not specify the SIL required for specific applications; does not give examples of determining the requirements for other methods of risk reduction. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Additional H&RA example(s) and quantitative analysis consideration annexes are provided.
