Publication Date: 2012-10

Language: EN
Pages: 50
Issue Num.:  12226 E
Commitee: CEI-CT56
Questa Norma definisce i principi base consolidati dell'analisi ad albero degli eventi (ETA, Event Tree Analysis) e fornisce una guida su come modellare le conseguenze di un evento scatenante così come sul modo di analizzare le conseguenze qualitative e quantitative nel contesto della fidatezza e delle misure correlate al rischio.
Più nel dettaglio, questa Norma tratta i seguenti argomenti in relazione all'albero degli eventi:

a) definizione dei termini essenziali e descrizione dell'uso dei simboli e loro rappresentazione grafica;
b) definizione dei passi procedurali nella costruzione di un albero degli eventi;
c) elaborazione delle ipotesi di partenza, dei limiti e dei benefici dell'esecuzione dell'analisi;
d) identificazione delle relazioni con altre tecniche per l'analisi di fidatezza e dei rischi correlati e chiarimenti sui campi di applicazione applicabili;
e) esposizione delle linee guida per gli aspetti qualitativi e quantitativi della valutazione;
f) esempi pratici di applicazione.

La Norma si applica a tutte le industrie nelle quali devono essere valutate la fidatezza e le misure correlate al rischio per le conseguenze di un evento scatenante.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.
La presente Norma recepisce il testo originale inglese della Pubblicazione 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.
