Anotace textu normy IEC 61508-2-ed.2.0 :
IEC 61508-2:2010 applies to any safety-related system, as defined by IEC 61508-1, that contains at least: - one electrical, electronic or programmable electronic element; - applies to all elements within an E/E/PE safety-related system; - specifies how to refine the E/E/PE system safety requirements specification, developed in accordance with IEC 61508-1, into the E/E/PE system design requirements specification; - specifies the requirements for activities that are to be applied during the design and manufacture of the E/E/PE safety-related systems except software, which is dealt with in IEC 61508-3. These requirements include the application of techniques and measures that: - are graded against the safety integrity level, for the avoidance of, and control of, faults and failures; - specifies the information necessary for carrying out the installation, commissioning and final safety validation of the E/E/PE safety-related system; - provides requirements for the preparation of information and procedures needed by the user for the operation and maintenance of the E/E/PE safety-related systems; - specifies requirements to be met by the organisation carrying out any modification of the E/E/PE safety-related systems. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. It has been subject to a thorough review and incorporates many comments received at the various revision stages. It has the status of a basic safety publication according to IEC Guide 104. NEW! Also available: IEC Standards+ 61508:2010, containing all parts, together with a commented Redline version. Changes made in this 2nd edition are highlighted and commented by a leading world expert. This publication is of high relevance for Smart Grid. La CEI 61508-2:2010 sapplique a tout systeme relatif a la securite tel que defini dans la CEI 61508-1, qui contient au moins: - un composant a base electrique, electronique ou electronique programmable; - sapplique a tous les elements dun systeme E/E/PE relatif a la securite; - specifie la maniere daffiner la specification des exigences de securite des systemes E/E/PE, developpee conformement a la CEI 61508-1, dans le cadre de la specification des exigences de conception des systemes E/E/PE; - specifie les exigences pour des activites qui doivent etre appliquees pendant la conception et la fabrication des systemes E/E/PE relatifs a la securite, a lexception du logiciel qui est traite dans la CEI 61508-3. Ces exigences comprennent lapplication de techniques et de mesures qui sont classees en fonction du: - niveau dintegrite de securite pour eviter et maitriser les anomalies et defaillances; - specifie les informations necessaires a linstallation, a la mise en service et a la validation finale de la securite des systemes E/E/PE relatifs a la securite; - fournit des exigences relatives a la preparation des informations et procedures necessaires a lutilisateur pour lexploitation et la maintenance des systemes E/E/PE relatifs a la securite; - specifie les exigences auxquelles doit satisfaire lentite qui effectue une modification des systemes E/E/PE relatifs a la securite. Cette deuxieme edition annule et remplace la premiere edition publiee en 1998 dont elle constitue une revision technique. Elle a fait lobjet dune revision approfondie et integre de nombreux commentaires recus lors des differentes phases de revision. Elle a le statut dune publication fondamentale de securite conformement au Guide CEI 104.
