What is BS EN 50129 - Safety-related electronic systems for railway signalling about?
BS EN 50129 is a safety standard for railway applications that discusses best practices for optimal performance of safety-related electronic systems for signalling. BS EN 50129 is applicable to safety-related electronic systems (including subsystems and equipment) for railway signalling applications. BS EN 50129 applies to generic systems (i.e., generic products or systems defining a class of applications), as well as to systems for specific applications. BS EN 50129 applies to all the phases of the life cycle of a safety-related electronic system, focusing in particular on phases from 5 (architecture and apportionment of system requirements) to 10 (system acceptance) as defined in EN 50126-1:2017. BS EN 50129 is primarily applicable to systems, subsystems, or equipment that have been specifically designed and manufactured for railway signalling applications. It should also be applied, so far as reasonably practicable, to general-purpose or industrial equipment (e.g., power supplies, display screens, or other commercial off-the-shelf items), which is procured for use as part of a safety-related electronic system. As a minimum, evidence should be provided in such cases to demonstrate either:
That the equipment is not relied on for safety, or That the equipment can be relied on for those functions which relate to safety
Note: BS EN 50129 is not applicable to existing systems, subsystems, or equipment that had already been accepted prior to the creation of this document. However, so far as reasonably practicable, it should be applied to modifications and extensions to existing systems, subsystems, and equipment. Note: I...
