Therefore cross-acceptance of Safety Approvals far systems, subsystems or equipment by the different national railway duty holders is necessary. This document is the corta-cc common European base for safety acceptance of electronic systems for railway signalling applications Cross-acceptance is aimed at the acceptance of generic products or generic applications that can be used for a number of different specific applications, and not at the acceptance of any single specific application Public procurement within the European Community concerning safety-related electronic systems for railway signalling applications will refer to this document This document is concerned with the evidence to be presented for the acceptance of safety-related systems. However, it specifies not only those life cycle activities which need to be completed before the acceptance stage, but also the additional planned activities to be carried out afterwards. In this way, safety ustification will cover the whole life cycle This document is concerned with what evidence is to be presented. Except where considered appropriate, it does not specify who carries out the necessary work, since this can vary in different circumstances Safety-related electronic systems for signalling include hardware and software aspects. To develop complete safety-related systems, both aspects need to be taken into account throughout the whole life cycle of the system. The requirements for the overall safety-related electronic system and for its hardware aspects are defined in this document. Other requirements are defined in associated CENELEC standards ①) for safety-related systems which include software, see EN 50128: for safety-related data communication, see EN 50159 This document consists of Clauses 1 to 8, which form the main part, and Annexes A, B, C,D, E, F,G and ZZ. The requirements defined in the main part of this document and in Annexes A, B,C and E are normative. whilst Annexes D. Fg and ZZ are informative This document is in line with and uses relevant sections of EN 50126-1: 2017, Railway Applications- The Specification and Demonstration of Reliability Availabiity, Maintainability and Satety(RAMS)-Part 1: Generic RAMS Process, EN 50126-2: 2017, Railway Applications- The Specification and Demonstration of Reliability, Availability, Maintainability and Safety(RAMs)- Part 2 Systems Approach to Safety. This document is based on the system life cycle described in EN 50126-1, EN 50126-2 and is in line with the En 61508 series. EN 50126-1, EN 50126-2, EN 50128 EN 50129 comprise the railway sector equivalent of the en 61508 series so far as railway Communication, Signalling and Processing Systems arc concerned. When compliance with thesc documents has bcen dcmonstrated, further cvaluation of compliance with the en 61508 series is not required BSEN50129:2018 EN50129:2018 1 Scope This document is applicable to safety-related electronic systems(including subsystems and equipment) for railway signalling applications This document applies to generic systems (i.e. generic products or systems defining a class of applications), as well as to systems for specific applicalions The scope of this document, and its relationship with other CENELEc standards are shown in Figure 1 This document is applicable only to the functional safety of systems. It is not intended to deal with other aspects of satety such as the occupational health and satety of personnel. While functional safety o systems clearly can have an impact on the safety of personnel, there are other aspects of system design which can also affect occupational health and safety and which are not covered by this document This document 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 Requirements for systems which are not related to safety are outside the scope of this document This document is not applicable to existing systems, subsystems or equipment which 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 This document is primarily applicable to systems, subsystems or equipment which 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 20①25≥0 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 (more information is given in 6.2)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 This document is aimed at railway duty holders, railway suppliers, and assessors as well as at safety authorities, although it does not define an approval process to be applied by the safety authorities 【实例截图】
