EN 61508-4:2010

Functional safety of electrical/electronic/programmable electronic safety-related systems - Part 4: Definitions and abbreviations

IEC 61508-4:2010 contains the definitions and explanation of terms that are used in parts 1 to 7 of the IEC 61508 series of standards. The definitions are grouped under general headings so that related terms can be understood within the context of each other. However, it should be noted that these headings are not intended to add meaning to the definitions. 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.

Funktionale Sicherheit sicherheitsbezogener elektrischer/elektronischer/programmierbarer elektronischer Systeme - Teil 4: Begriffe und Abkürzungen

Sécurité fonctionnelle des systèmes électriques/électroniques/électroniques programmables relatifs à la sécurité - Partie 4: Définitions et abréviations

La CEI 61508-4:2010 contient les définitions et explications des termes utilisés dans les parties 1 à 7 de la série de normes CEI 61508. Les définitions sont regroupées sous des titres généraux de telle sorte que les termes qui sont en rapport puissent être compris dans le contexte des autres. Toutefois, il convient de remarquer que ces titres ne sont pas attribués pour ajouter un sens aux définitions. 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. Elle a le statut d'une publication fondamentale de sécurité conformément au Guide CEI 104.

Funkcijska varnost električnih/elektronskih/elektronsko programirljivih varnostnih sistemov - 4. del: Definicije in kratice (IEC 61508-4:2010)

1.1 Ta del IEC 61508 vsebuje definicije in razlago izrazov, ki se uporabljajo v delih od 1 do 7 serije standardov IEC 61508.
1.2 Definicije so razporejene pod splošnimi naslovi, tako da se povezani izrazi lahko razumejo v kontekstu drug drugega. Opozoriti pa je treba, da naslovi definicijam ne dodajajo pomena.
1.3 IEC 61508-1, IEC 61508-2, 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.
1.4 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.
1.5 Slika 1 prikazuje celoten okvir serije IEC 61508 in nakazuje vlogo IEC 61508-4 pri doseganju funkcijske varnosti varnostnih sistemov E/E/PE.
