Sebbene l'oggetto della presente Norma non sia ancora oggetto di una Pubblicazione IEC, è tuttavia in corso, in sede internazionale, uno studio che verrà pubblicato come modifica alla Pubblicazione IEC 570 (1985). Si applica ai sistemi di alimentazione a binario elettrificato con due o più poli per la connessione alla rete di apparecchi di illuminazione, sia con tensione nominale tra i poli non superiore a 440 V con dispositivo di messa a terra (CL. I), sia con bassissima tensione di sicurezza (BTS) non superiore a 24 V senza dispositivo di messa a terra (CL. III). Si applica anche a binari misti, con parti in Classe III sostenute da binari in Classe I. I sistemi di alimentazione a binario elettrificato possono anche garantire il supporto meccanico degli apparecchi di illuminazione.
Deve essere usata congiuntamente alla CEI 34-17 (1989) - fasc. 1263, di cui costituisce integrazione e modifica.

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.
