La presente Norma specifica i requisiti costruttivi e le prove per le apparecchiature a sicurezza intrinseca destinate ad essere utilizzate in atmosfera esplosiva e per le apparecchiature associate destinate al collegamento a circuiti a sicurezza intrinseca che entrano in tale atmosfera esplosiva. Questo tipo di protezione si applica alle apparecchiature elettriche nelle quali i circuiti elettrici stessi non sono nelle condizioni di provocare un'esplosione nell'atmosfera esplosiva circostante. La Norma è applicabile anche alle apparecchiature elettriche o parti di esse situate al di fuori dell'atmosfera esplosiva o protette da un altro tipo di protezione secondo la Norma CEI EN IEC 60079-0, ove la sicurezza intrinseca dei circuiti elettrici nell'atmosfera esplosiva può dipendere dalla progettazione e dalla costruzione di tali apparecchiature elettriche o da parti di esse. I requisiti per i sistemi a sicurezza intrinseca sono forniti dalla norma CEI EN IEC 60079-25. La presente Norma sostituisce totalmente la CEI EN 60079-11 - Fascicolo 12061 che rimane applicabile fino al 31/12/2027.

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.
