La presente Norma fornisce prescrizioni per la progettazione e la costruzione di sistemi di messa a terra di impianti elettrici con tensione nominale superiore a 1 kV in c.a. e frequenza nominale fino a 60 Hz inclusa, al fine di consentire un funzionamento adeguato e sicuro per l'uso previsto.
Il presente documento non si applica alla progettazione e realizzazione di sistemi di messa a terra per:
- linee aeree e sotterranee tra impianti separati;
- binari e materiale rotabile elettrificati;
- apparecchiature ed impianti in miniere;
- installazioni di lampade fluorescenti;
- installazioni su navi ed impianti off-shore;
- apparecchiature elettrostatiche (per esempio precipitatori elettrostatici, unità per verniciatura a spruzzo);
- sale prova;
- apparecchiature mediche, per esempio apparecchiature a raggi X.
Il presente documento non include i requisiti per l'esecuzione dei lavori sotto tensione su impianti elettrici.
La Norma in oggetto sostituisce completamente la Norma CEI EN 50522:2011-07, che rimane applicabile fino al 10-01-2025.
Questa Norma viene pubblicata dal CEI in una prima fase nella sola lingua inglese, per consentirne l'immediato utilizzo da parte degli utenti interessati, nel rispetto della data di pubblicazione fissata dagli Enti Normatori Internazionali.
Successivamente il CEI pubblicherà, in un nuovo fascicolo, la versione solo italiana; tale versione avrà la stessa validità della presente.
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.
