1 Scope This standard specifies RAMS in terms of reliability, availability, maintainability and safety and their interaction; specifies a process, based on the system life cycle and tasks within it, for managing RAMS; enables conflicts between RAMS elements to be controlled and managed effectively; specifies a systematic process for specifying requirements for RAMS and demonstrating that these requirements are achieved. This standard does not specifies RAMS targets, quantities, requirements or solutions for specific railway applications; does not specifies requirements for ensuring system security; such requirements shall be specified in sub-standards of RAMS for specific railway applications. This standard is applicable: a) to the specification and demonstration of RAMS for all railway applications and at all levels of such an application, as appropriate, from complete railway routes to major systems within a railway route, and to individual and combined sub-systems and components within these major systems, including those containing software; in particular: — to new systems, — to new systems integrated into existing systems in operation prior to the creation of this standard, although it is not generally applicable to other aspects of the existing system, — to modifications of existing systems in operation prior to the creation of this standard; although it is not generally applicable to other aspects of the existing system; b) at all relevant phases of the life cycle of an application; c) for use by Railway Authorities and railway support industry. Note: Guidance on the applicability is given in the requirements of this standard. 2 Normative References The following normative document contains provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies.
