功能安全评估 第二部分:安全评估的执行、报告和后续跟踪

Functional Safety Assessment Part 2:Performing,Reporting and Following up of the Functional Safety Assessment

功能安全评估(FSAs)是在传统的安全生命周期活动如验证,确认和功能安全审核之外进行的。这些安全生命周期活动通常直接由安全相关系统的项目团队在执行阶段进行计划和实施。功能安全评估的目的在于独立地确保功能安全在机构特定的供货范围内得以实现.在本指南的第二部分我们着重讨论执行功能安全评估所采用的与生命周期相吻合的3阶段方法论,并对功能安全评估的报告和后续跟踪作了描述。

Functional Safety Assessments （FSAs） are undertaken in addition to the traditional safety lifecycle activities of verification, validation and functional safety audits. These safety lifecycle activities are typically planned and executed directly by the Safety-Related Systems project team implementing phase（s） of the safety lifecycle. The purpose of a FSA is to independently ensure that functional safety has been achieved within the specific scope of supply for the organization（s） in the context of the safety lifecycle. In this second part of the guide, we describe the methodology for performing the functional safety assessment including a three stage approach aligned to the safety lifecycle. In addition, the reporting of the functional safety assessment and follow-up activities are described.
