Anotation

Gives requirements related to the avoidance of CCF of I&C systems that perform category A functions; additionally requires the implementation of independent I&C systems to overcome CCF, while the likelihood of CCF is reduced by strictly applying the overall safety principles of IEC SC 45A (notably IEC 61226, IEC 61513, IEC 60880 and IEC 60709); gives an overview of the complete scope of requirements relevant to CCF. Fournit des exigences relatives a levitement des DCC dans les systemes dI&C realisant des fonctions de categorie A; exige de facon complementaire la mise en oeuvre de systemes dI&C independants pour surmonter les DCC, lorsque la probabilite doccurrence des DCC est deja reduite en appliquant strictement les principes de surete prevalant au SC 45A de la CEI (en particulier ceux enonces dans les CEI 61226, CEI 61513, CEI 60880 et CEI 60709); donne une vue generale du domaine complet des exigences applicables aux DCC.
