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
