La presente Norma è la versione italiana della Norma Europea CENELEC EN 50019 e suo Corrigendum (aprile 1994).
Prescrive le regole specifiche di costruzione, prova e contrassegno delle costruzioni elettriche con modo di protezione a sicurezza aumentata “e” destinate ad essere utilizzate in atmosfere esplosive con presenza di gas. Queste regole specifiche completano le regole generali della EN 50014 che sono applicabili al modo di protezione “e”. La Norma si applica alle costruzioni elettriche che hanno una tensione nominale d'alimentazione non superiore a 11 kV in corrente alternata (valore efficace) o in corrente continua, e che in servizio ordinario non producono né archi, né scintille, né temperature pericolose.
La presente Norma è destinata a sostituire la precedente versione (ed. 1972, fasc. 458 e relative Varianti), la quale rimane tuttavia in vigore in quanto è la sola, fino ad ora, ad essere considerata dalla legislazione italiana di recepimento della Direttiva Comunitaria Materiali EX.
La presente Norma deve essere utilizzata congiuntamente alla Norma CEI 31- 8 (fascicolo 2057 E).

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.
