What is BS EN 50126-2-Systems Approach to Safety during RAMS procedure about?
BS EN 50126 is a European standard that discusses specification and demonstration of reliability, availability, maintainability, and safety (RAMS). BS EN 50126-2 provides the best industry guidance on the systems approach to safety to ensure the safety of RAMS to minimize the hazards.
BS EN 50126-2 is the second part of a multi-part series that:
- Considers the safety-related generic aspects of the RAMS life cycle
- Defines methods and tools which are independent of the actual technology of the systems and subsystems
- Provides the user of BS EN 50126-2 with the methods to assure safety concerning the system under consideration and its interactions
- Guides about the definition of the system under consideration, including identification of the interfaces and the interactions of this system with its subsystems or other systems, to conduct the risk analysis
BS EN 50126-2 applies to railway applications fields, namely Command, Control, and signaling, Rolling Stock, and Fixed Installations, and specifically:
- To the specification and demonstration of safety for all railway applications and at all levels of such an application, as appropriate, from complete railway systems to major systems and to individual and combined sub-systems and components within these major systems, including those containing software
- At all relevant phases of the life cycle of an application
- For use by railway duty holders and the railway suppliers
Note 1:BS EN 50126-2 does not define:
- RAMS targets, quantities, requirements, or solutions for specific railway applications
- Rules or processes about the certification of railway products against the requirements of this standard
- An approval process by the safety authority
Note 2: It is not required to apply BS EN 50126-2 to existing systems which remain unmodified, including those systems already compliant with any former version of EN 50126.
Note 3: BS EN 50126-2 assumes that railway duty holders and railway suppliers have business-level policies addressing Quality, Performance, and Safety. The approach defined in this standard is consistent with the application of quality management requirements contained within EN ISO 9001.
Who is BS EN 50126-2-Systems Approach to Safety during RAMS procedure for?
BS EN 50126-2 on Systems Approach to Safety RAMS for railway applications is useful for:
- Personnel or Staff in charge of RAMS Process in railways
- Developers of RAMS
- Regulatory authorities
Why should you use BS EN 50126-2-Systems Approach to Safety during RAMS procedure?
RAMS systems-based approach to safety requires the application of scientific, technical, and managerial skills to hazard identification, hazard analysis, and elimination, control, or management of hazards throughout the lifecycle of a system, program, project, activity, or product.
BS EN 50126-2 guideline assists you with the safety process, safety demonstration, safety acceptance, organization of roles, independence of roles, risk assessment, specification of system safety requirements, apportionment of functional safety integrity requirements, design, and implementation for a systems approach to safety for reliability, availability, maintainability, and safety (RAMS) for railway applications.
With obedience and compliance of BS EN 50126-2, you can take appropriate decisions to minimize the hazards faced during the RAMS procedure. And also provide safety-related functions to ensure safety.
What’s changed since the last update?
BS EN 50126-2:2017 supersedes PD CLC/TR 50126-2:2007, which is withdrawn. BS EN 50126-2:2017 has modified its scope compared to PD CLC/TR 50126-2:2007.
