La presente Norma, da utilizzare congiuntamente alla CEI EN 50085-1:2006-03, specifica le prescrizioni e le prove per i sistemi di canali (CTS) e per i sistemi di condotti (CDS), destinati all'alloggiamento di conduttori isolati, cavi ed eventualmente di altre apparecchiature elettriche e, se necessario, alla loro separazione ai fini della protezione elettrica, nelle installazioni elettriche e/o nei sistemi di telecomunicazione. La tensione massima di queste installazioni è 1 000 V in corrente alternata e 1 500 V in corrente continua. Le colonne e le torrette sono destinate al montaggio in spazio libero e in contatto con le o la superficie di montaggio solo a una o a due estremità. Il montaggio avviene fissandole o ponendole sul pavimento con una base zavorrata o collegata alla superficie di montaggio tramite un componente flessibile. La presente Norma non si applica ai sistemi di tubi, ai sistemi di passerelle o passerelle a traversini porta cavi, ai sistemi di canalizzazione elettrificata o ai prodotti trattati da altre Norme. La Norma in oggetto sostituisce completamente la Norma CEI 23-73:2001-12, che rimane applicabile fino al 01-05-2012. La presente Norma riporta il testo in inglese e italiano della EN 50085-2-4; rispetto al precedente fascicolo n. 10638E di agosto 2010, essa contiene la traduzione completa della EN sopra indicata. La presente Norma è annullata e sostituita dalla CEI EN IEC 61084-2-4:2024-10 (CEI 23-108), tuttavia rimane applicabile fino al 08/05/2029 .

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.
