本文件为轨道交通系统中用于安全关键应用的基于处理器的设备提供了一套标准验证任务。本标准的范围应包括并仅限于验证在执行要求故障安全的安全关键功能时达到的安全水平的过程。它不涉及质量保证或验证过程，这些过程也会影响所实现的总体系统安全水平。

This document provides a set of standard verification tasks for processor-based equipment used in safety critical applications on rail and transit systems. The scope of the standard shall encompass and be limited to processes which verify the level of safety achieved in the implementation of safety critical functions which are required to be fail-safe. It does not address quality assurance or validation processes which also affect the level of overall system safety achieved.
