Questa Norma contiene informazioni e guide sulla EN/IEC 61508-2 e EN/IEC 61508-3. L'allegato A fornisce una breve panoramica sui requisiti della CEI EN/IEC 61508-2 e EN/IEC 61508-3 e stabilisce i passi funzionali per la loro applicazione. L'allegato B invece da un esempio tecnico per calcolare le probabilità di anomalia hardware e dovrebbe essere letto insieme al 7.4.3 e all'allegato C della EN/IEC 61508-2 e all'allegato D. L'allegato C illustra un esempio di calcolo per la copertura diagnostica e dovrebbe essere letto insieme all'allegato C della EN/IEC 61508-2. L'allegato D propone una metodologia per quantificare l'effetto sulla probabilità di guasto delle anomalie hardware di causa comune. L'allegato E descrive degli esempi applicativi per le tabelle dei livelli di integrità del software di cui all'allegato A della EN/IEC 61508-3, livelli di integrità di sicurezza 2 e 3.
La Norma in oggetto sostituisce completamente la Norma CEI EN 61508-6:2002-11 che rimane applicabile fino al 01-05-2013, di cui costituisce una revisione tecnica, ed ha lo stato di Norma di base di sicurezza in accordo alla Guida 104 della IEC.

ICS

International Classification for Standards (ICS) is an international classification system for technical standards.

The ICS is a hierarchical classification organized on three levels.

Level 1 covers the main fields of activity in standardization, e.g. road vehicle engineering, agriculture, metallurgy.

Each field has a two-digit notation, e.g.

  43    Road Vehicle Engineering

The main fields are subdivided into groups (level 2). The notation of a group consists of the field notation and a three-digit group number, separated by a point, e.g.

  43.040    Road vehicle systems

Some groups are further divided into sub-groups (level 3). The notation of a sub-group consists of the group notation and a two-digit number, separated by a point, e.g.

  43.040.20 Lighting, signaling and warning devices

You can identify the ICS code of your interest by typing the code or a keywordword in the dropdown ICS field, and by selecting one of the filtered results.

Search also in the summary/description of the standard

By flagging this control, the search for keywords will not be limited to the Standard Number and Title fields, but will also be performed in the Abstract of the standard.

This way, you will get more results.

You should use this option when you can not find the desired result with the standard approach and it is necessary to extend the scope of the search: by increasing the number of results, you will increase the number of non-relevant elements, as well.
