CEI EN IEC 61439-1 - Apparecchiature assiemate di protezione e di manovra per bassa tensione (quadri BT). Parte 1: Regole generali. Pacchetto Norma base e VERSIONE REDLINE

PAGES:  296
Si tratta di un pacchetto composto da Norma CEI e Documento di confronto, denominato “Versione Redline”.
La versione Redline è un ausilio all’identificazione delle
differenze tra la Norma CEI EN IEC 61439-1 del 2022 e la Norma CEI EN 61439-1 del 2012, entrambe in lingua inglese.

La Norma CEI EN IEC 61439-1 stabilisce le definizioni generali, le condizioni di servizio, le prescrizioni di costruzione, le caratteristiche tecniche e i requisiti di verifica per le apparecchiature assiemate di protezione e manovra per bassa tensione (quadri BT).

La Versione Redline non è una pubblicazione normativa e può essere
acquistata solo insieme alla Norma CEI EN IEC 61439-1 del 2022 - che rimane l’unico riferimento normativo in vigore sull’argomento - in un pacchetto pensato ad hoc.
Per maggiori informazioni o per acquistare il pacchetto, contattare il CEI:



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.
