Versione italiana della Norma Europea CENELEC EN 60947-3 più Corrigendum giugno 1992 e marzo 1993, equivalente alla Pubblicazione IEC 947-3 (1990) più Corrigendum (dicembre 1991), con il testo originale nella versione inglese a fronte del testo italiano, la Norma si applica agli interruttori di manovra, ai sezionatori, agli interruttori di manovra-sezionatori e alle unità combinate con fusibili, destinati a circuiti di distribuzione e di alimentazione di motori, la cui tensione nominale non supera i 1000 V in corrente alternata o 1500 V in corrente continua.
Essa ha lo scopo di fissare:
– le caratteristiche dell'apparecchiatura;
– le condizioni che l'apparecchiatura deve soddisfare relativamente a funzionamento e comportamento in servizio ordinario e in condizioni anormali, e a proprietà dielettriche;
– le prove per verificare se queste condizioni sono soddisfatte e i metodi da utilizzare per queste prove;
– i dati da riportare sull'apparecchiatura o forniti dal costruttore
La norma non contiene le prescrizioni addizionali necessarie per apparecchiature elettriche in atmosfere di gas esplosive e non si applica alle apparecchiature oggetto delle Pubblicazioni IEC 947-2 (CEI 17-5), IEC 947-4-1 (CEI 17-50) e IEC 947-5-1 (CEI 17-45), fatte salve le eccezioni evidenziate.

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.
