Tali Norme, che contengono in allegato la traduzione della Norma Europea CENELEC EN 50014, danno le «Regole generali» di realizzazione delle costruzioni elettriche destinate ad essere utilizzate in atmosfere potenzialmente esplosive per assicurare che queste costruzioni non provochino l'esplosione dell'atmosfera circostante. Esse sono completate o modificate da Norme Europee specifiche per ciascun modo di protezione normalizzato, ovvero CEI 31-1 - fasc.472, CEI 31-2 - fasc.471, CEI 31-5 - fasc. 456, CEI 31-6 - fasc.457, CEI 31-7 - fasc. 458, CEI 31- 9 - fasc. 473.
La ristampa in F.to A4 è comprensiva delle Varianti V 1 e V 2 sinora uscite.
N.B.: Le Norme e Varianti considerate sono oggetto del DPR 675/82 e del DM 5 ottobre 1984 che recepiscono rispettivamente le Direttive CEE n. 196/79 e n. 47/84.
Si rende noto che attualmente si può applicare solo la prima edizione (1977) della EN 50014 (CEI 31-8-fasc.459) in quanto la seconda edizione (1992) (CEI 31-8-fasc.2057E) non è ancora stata recepita da una Direttiva comunitaria "Vecchio Approccio" e non è ancora entrata in funzione la Direttiva "Nuovo Approccio" n. 94/9/CE che sarà resa operativa solo il 1° marzo 1996. A partire da questa data ci sarà poi un periodo transitorio di validità in parallelo, fino al 30 giugno 2003, in cui entrambe potranno essere utilizzate.

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.
