EN 61511-1:2004

Functional safety - Safety instrumented systems for the process industry sector - Part 1: Framework, definitions, system, hardware and software requirements

Gives requirements for the specification, design, installation, operation and maintenance of a safety instrumented system, so that it can be confidently entrusted to place and/or maintain the process in a safe state. This standard has been developed as a process sector implementation of EN 61508.

Funktionale Sicherheit - Sicherheitstechnische Systeme für die Prozessindustrie - Teil 1: Allgemeines, Begriffe, Anforderungen an Systeme, Software und Hardware

Sécurité fonctionnelle - Systèmes instrumentés de sécurité pour le secteur des industries de transformation - Partie 1: Cadre, définitions, exigences pour le système, le matériel et le logiciel

permet de définir des prescriptions relatives aux spécifications, à la conception, à l'installation, à l'exploitation et à l'entretien d'un système instrumenté de sécurité, de telle manière qu'il puisse être mis en oeuvre en toute confiance, et ainsi établir et/ou maintenir les processus dans un état de sécurité convenable. La présente norme a été conçue pour être une mise en uvre de la norme internationale CEI 61508 "Sécurité fonctionnelle des systèmes électriques/électroniques/ électroniques programmables relatifs à la sécurité" dans le domaine de l'industrie des processus. Le contenu du corrigendum de novembre 2004 a été pris en considération dans cet exemplaire. Elle a le statut d'une norme horizontale conformément au Guide 108 de la CEI.
