Annotation of standard text IEC 61508-6-ed.2.0 :
IEC 61508-6:2010 contains information and guidelines on IEC 61508-2 and IEC 61508 3. Annex A gives a brief overview of the requirements of IEC 61508-2 and IEC 61508-3 and sets out the functional steps in their application. Annex B gives an example technique for calculating the probabilities of hardware failure and should be read in conjunction with 7.4.3 and Annex C of IEC 61508-2 and Annex D. Annex C gives a worked example of calculating diagnostic coverage and should be read in conjunction with Annex C of IEC 61508-2. Annex D gives a methodology for quantifying the effect of hardware-related common cause failures on the probability of failure. Annex E gives worked examples of the application of the software safety integrity tables specified in Annex A of IEC 61508-3 for safety integrity levels 2 and 3. 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. 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 61508-6:2010 contient des informations et lignes directrices sur la CEI 61508-2 et la CEI 61508-3. LAnnexe A presente un bref apercu des exigences de la CEI 61508-2 et de la CEI 61508-3 et etablit les etapes fonctionnelles de leur application. LAnnexe B donne une technique servant dexemple pour le calcul des probabilites de defaillance du materiel; il convient de la lire conjointement au 7.4.3 et a lAnnexe C de la CEI 61508-2, et a lAnnexe D. LAnnexe C donne un exemple elabore de calcul de la couverture de diagnostic; il convient de la lire conjointement avec lAnnexe C de la CEI 61508-2. LAnnexe D donne une methodologie de quantification de leffet des defaillances de cause commune relatives au materiel sur la probabilite de defaillance. LAnnexe E donne des exemples dapplication des tableaux dintegrite de securite du logiciel specifies dans lAnnexe A de la CEI 61508-3 pour les niveaux 2 et 3 dintegrite de 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.
