Il presente fascicolo informa che la Guida CEI 31-35/A:2012-11 "Atmosfere esplosive - Guida alla classificazione dei luoghi con pericolo di esplosione per la presenza di gas in applicazione della Norma CEI EN 60079-10-1 (CEI 31-87): esempi di applicazione" è abrogata dal 14 ottobre 2018 in quanto la Norma di riferimento CEI EN 60079-10-1:2010-01 (CEI 31-87) è superata da edizione successiva.
Il Sotto Comitato CEI SC 31J "Impianti elettrici nei luoghi con pericolo di esplosione" ritiene che i contenuti tecnici della Guida CEI 31-35/A:2012-11, abrogata, rappresentino un utile riferimento, per le metodologie scientifiche in essa contenute, relativamente alle parti non in contrasto con la nuova edizione della Norma CEI EN 60079-10-1:2016-11, nell’ambito delle scelte affidate al valutatore/classificatore.

Standard Evolution

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.
