IEC 61508-7:2010 contains an overview of various safety techniques and measures relevant to IEC 61508-2 and IEC 61508-3.The references should be considered as basic references to methods and tools or as examples, and may not represent the state of the art. 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.

Funktionale Sicherheit sicherheitsbezogener elektrischer/elektronischer/programmierbarer elektronischer Systeme - Teil 7: Überblick über Verfahren und Maßnahmen

Sécurité fonctionnelle des systèmes électriques/électroniques/électroniques programmables relatifs à la sécurité - Partie 7: Présentation de techniques et mesures

La CEI 61508-7:2010 contient une présentation de différentes techniques et mesures de sécurité pertinentes pour la CEI 61508-2 et la CEI 61508-3. Il convient que les références citées soient considérées comme des références fondamentales des méthodes et outils, ou comme des exemples; elles peuvent ne pas représenter la technologie de pointe. Cette deuxième édition annule et remplace la première édition publiée en 1998 dont elle constitue une révision technique. Elle a fait l'objet d'une révision approfondie et intègre de nombreux commentaires reçus lors des différentes phases de révision.

Funkcijska varnost električnih/elektronskih/elektronsko programirljivih varnostnih sistemov - 7. del: Pregled tehnik in ukrepov (IEC 61508-7:2010)

1.1 Ta del IEC 61508 vsebuje pregled različnih varnostnih tehnik in ukrepov, pomembnih za IEC 61508-2 in IEC 61508-3.
Reference je treba obravnavati kot osnovne reference za metode in orodja ali kot primere in morda ne predstavljajo zadnjega stanja.
1.2 IEC 61508-1, IEC 61598-2, IEC 61508-3 in IEC 61508-4 so osnovne varnostne objave, čeprav ta status ne velja v okviru nezapletenih varnostnih sistemov E/E/PE (glej točko 3.4.3 IEC 61508-4). Kot osnovne varnostne objave so namenjeni temu, da jih uporabljajo tehnični odbori pri pripravi standardov v skladu z načeli, opredeljenimi v Vodilu IEC 104 in Vodilu ISO/IEC 51. IEC 61508-1, IEC 61508-2, IEC 61508-3 in IEC 61508-4 se lahko tudi uporabijo kot samostojne objave. Horizontalno varnostno delovanje tega mednarodnega standarda ne velja za medicinsko opremo v skladu s serijo IEC 60601.
1.3 Ena od odgovornosti tehničnega odbora je, če je primerno, da uporabi temeljne varnostne objave pri pripravi svojih objav. V tem okviru zahteve, preskusne metode ali preskusni pogoji te temeljne varnostne objave ne veljajo, razen če se objave, ki so jih pripravili tehnični odbori, nanje izrecno sklicujejo ali jih vključujejo.
1.4 Slika 1 prikazuje celoten okvir za dele od 1 do 7serije IEC 61508 in nakazuje vlogo IEC 61508-7 pri doseganju funkcijske varnosti varnostnih sistemov E/E/PE.
