为铁路部门和铁路支持行业提供一个流程，使其能够实施一致的可靠性、可用性、可维护性和安全性管理方法，简称RAMS。RAMS要求的规范和演示过程是本标准的基石。它旨在促进对RAMS管理的共识和方法。 可由铁路局和铁路支持行业在铁路应用生命周期的所有阶段系统地应用，以制定铁路特定的RAMS要求，并实现对这些要求的遵守。本标准定义的系统级方法有助于评估复杂铁路应用各要素之间的RAMS相互作用

Provides Railway Authorities and railway support industry with a process which will enable the implementation of a consistent approach to the management of reliability, availability, maintainability and safety, denoted by the acronym RAMS. Processes for the specification and demonstration of RAMS requirements are the cornerstones of this standard. It aims to promote a common understanding and approach to the management of RAMS. Can be applied systematically by a Railway Authority and railway support industry, throughout all phases of the life cycle of a railway application, to develop railway specific RAMS requirements and to achieve compliance with these requirements. The systems-level approach defined by this standard facilitates assessment of the RAMS interactions between elements of complex railway applications
