Functional safety - Safety instrumented systems for the process industry sector - Part 2: Guidelines for the application of IEC 61511-1
IEC 61511-2:2016 is available as IEC 61511-2:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61511-2:2016 provides guidance on the specification, design, installation, operation and maintenance of SIFs and related SIS as defined in IEC 61511-1:2016. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: guidance examples based on all phases of the safety life cycle provided based on usage experience with IEC61511 1st edition; annexes replaced to address transition from software to application programming.

L'IEC 61511-2 :2016 donne les lignes directrices relatives à la spécification, la conception, l'installation, au fonctionnement et à la maintenance des SIF et des SIS associés, telles que définies dans l'IEC 61511-1:2016. Cette deuxième édition annule et remplace la première édition parue en 2003. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: description des exemples d'orientation, basés sur toutes les phases du cycle de vie de sécurité, réalisée avec des exemples basés sur l'expérience de l'utilisation de la norme IEC 61511 première édition; remplacement des annexes pour répondre à la transition de logiciel à programmation d'application.
Funkcijska varnost - Sistemi z varnostnimi instrumenti za sektor procesne industrije - 2. del: Smernice za uporabo IEC 61511-1 (IEC 61511-2:2016)
Ta del standarda IEC 61511 določa zahteve za specifikacijo, zasnovo, namestitev, delovanje in vzdrževanje funkcij z varnostnimi instrumenti in povezanimi sistemi z varnostnimi instrumenti, kot je določeno v standardu IEC 61511-1:2016.
OPOMBA 1: Dodatek A (informativni) je bil organiziran na način, da vsaka številka točke in podtočke obravnava ustrezno številko točke in podtočke v standardu IEC 61511-1:2016, s to razliko, da pred njimi stoji »A«.
OPOMBA 2: Dodatek A zdaj vsebuje material, ki je bil prej v besedilu prve izdaje. Te spremembe so potrebne zaradi skladnosti s pravili IEC, ki prepovedujejo, da bi bil standard v celoti informativen.
OPOMBA 3: Da bi lahko v kar največji meri uporabili te smernice:
– si oglejte napotke za razdelke in posamezne točke (npr. ko iščete napotke za 5.2.6.1.3, upoštevajte napotke v točki 5.2.6);
– kadar ni na voljo napotkov za določeno točko (npr. ni dodatnih napotkov), si oglejte tudi napotke za razdelek, saj so lahko uporabni).
OPOMBA 4: Primeri, navedeni v dodatkih tega standarda, se navezujejo na posamezne primere uporabe zahtev iz standarda IEC 61511 v določenem primeru, uporabnik pa se mora prepričati, da so izbrane metode in tehnike primerne v njegovem primeru.
