La presente Guida, elaborata dal SC 106A del CEI, "Esposizione umana ai campi elettromagnetici: bassa frequenza" ha lo scopo di fornire gli elementi fondamentali per il calcolo dei campi elettrici e magnetici a 50 Hz generati da linee, aeree e in cavo, e da cabine e stazioni elettriche. Essa è una revisione della Guida CEI 211-4:1996, per integrarla con metodi di calcolo del campo magnetico applicabili ad molte situazioni di interesse pratico non coperte dalla precedente edizione; fornisce inoltre indicazioni generali sulle metodologie disponibili per il calcolo del campo elettrico.
La Guida CEI 211-4:1996 era stata infatti redatta per formulare un metodo di calcolo del campo elettrico e del campo magnetico generati dalle linee elettriche aeree, che coprisse i casi di maggiore interesse riscontrabili in pratica per tali linee. Non era però applicabile a tutte le geometrie di linee aeree e in cavo e alle stazioni elettriche perché i metodi esposti nella suddetta precedente edizione, sviluppati limitatamente a geometrie bidimensionali, restavano applicabili soltanto alle linee, aeree e in cavo, nell'intorno delle quali i conduttori potevano essere considerati paralleli tra di loro e rispetto alla superficie del terreno (perlomeno per un tratto sufficientemente lungo rispetto alle distanze tra i conduttori stessi).

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.
