Anotace textu normy IEC 62278-1-ed.1.0 :
IEC 62278-1:2025 addresses railway specifics, enables conflicts between RAMS elements to be controlled and managed effectively. This document specifies: a) a process, based on the system life cycle and tasks within it, for managing RAMS; b) a systematic process, tailorable to the type and size of the system under consideration, for specifying requirements for RAMS and demonstrating that these requirements are achieved. This document does not specify: c) RAMS targets, quantities, requirements or solutions for specific railway applications; d) rules or processes pertaining to the certification of railway products against the requirements of this document; e) an approval process for the railway stakeholders. This document is applicable to railway application fields, including signalling, rolling stock and fixed installations, and specifically: f) to the specification and demonstration of RAMS 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 subsystems and components within these major systems, including those containing software; in particular: - to new systems; - to new systems integrated into existing systems already accepted, but only to the extent and insofar as the new system with the new functionality is being integrated. It is otherwise not applicable to any unmodified aspects of the existing system; - as far as reasonably practicable, to modifications and extensions of existing systems already accepted, but only to the extent and insofar as existing systems are being modified. It is otherwise not applicable to any unmodified aspect of the existing system; g) at all relevant phases of the life cycle of an application; h) for use by railway duty holders and the railway suppliers. This document is not applicable to: i) any unmodified aspects of the existing system; j) existing systems which remain unmodified, including those systems already compliant with IEC 62278:2002. This first edition, together with IEC 62278-2, cancels and replaces IEC 62278:2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) added 5.2 on multi level system approach; b) added 5.3 on railway system overview; c) added 5.9 on risk reduction strategy; d) updated the content of correlation of RAMS management process and system life cycle in 6.2; e) added 6.4 on organizational requirements; f) added 6.5 on application of this document and adaptability to project scope and size; g) added 6.8 on independent safety assessment; h) added Clause 8 on safety case; i) added Annex D providing guidance on system definition; The IEC 62278 series forms part of the railway sector specific application of IEC 61508. IEC 62278, IEC 62279 and IEC 62425 comprise the railway sector equivalent of the IEC 61508 series so far as railway communication, signalling and processing systems are concerned. When compliance with these documents has been demonstrated, further evaluation of compliance with the IEC 61508 series is not foreseen. A list of all parts in the IEC 62278 series, published under the general title Railway applications – Specification and demonstration of reliability, availability, maintainability and safety (RAMS), can be found on the IEC website. LIEC 62278-1:2025 prend en compte les specificites du domaine ferroviaire et permet de controler et de gerer efficacement les conflits entre les composantes de la FDMS. Le present document specifie : a) un processus de management de la FDMS fonde sur le cycle de vie du systeme et les taches qui en font partie ; b) un processus systematique adaptable au type et a la taille du systeme en cours dexamen, permettant de specifier les exigences de la FDMS et de demontrer que ces exigences sont satisfaites. Le present document ne specifie pas : c) les objectifs de FDMS, ni les grandeurs, les exigences ou les solutions pour des applications ferroviaires specifiques ; d) les regles ou les processus de certification des produits ferroviaires vis-a-vis des exigences du present document ; e) un processus dhomologation pour les parties prenantes ferroviaires. La presente Partie 1 de lIEC 62278 sapplique aux domaines dapplication ferroviaire, y compris controle-commande et signalisation, materiel roulant et installations fixes, et specifiquement : f) a la specification et a la demonstration des exigences de FDMS pour toute application ferroviaire et a tout niveau dune telle application, selon le cas, allant des systemes ferroviaires complets aux grands systemes et aux sous-systemes et equipements (individuels et combines) de ces grands systemes, y compris ceux qui comportent des logiciels. Elle est notamment applicable : 1) aux nouveaux systemes ; 2) aux nouveaux systemes integres dans des systemes preexistants acceptes, mais seulement dans la mesure ou, et dans la facon dont le nouveau systeme comprenant la nouvelle fonctionnalite y est integre. Elle nest sinon pas applicable aux parties inchangees du systeme existant ; 3) dans toute la mesure du possible, aux modifications et extensions des systemes preexistants, mais seulement dans la mesure ou, et dans la facon dont les systemes existants sont modifies. Elle nest sinon pas applicable aux parties inchangees du systeme existant ; g) a toutes les phases concernees du cycle de vie dune application donnee ; h) a lutilisation des societes dexploitation ferroviaire et des industries ferroviaires. Le present document ne sapplique pas : i) a tout aspect non modifie du systeme existant ; j) aux systemes existants qui demeurent non modifies, y compris les systemes deja conformes a lIEC 62278:2002. LIEC 62278-1:2025 conjointement a lIEC 62278-2, annule et remplace lIEC 62278:2002. Cette edition constitue une revision technique. Cette edition inclut egalement les modifications techniques majeures suivantes par rapport a l
