La presente Norma europea è applicabile agli apparati nuovi di fabbrica per la misura di energia elettrica attiva, utilizzata in ambito residenziale, commerciale e industriale su reti elettriche a 50Hz.
Tale Norma indica le prescrizioni generali ed i metodi di prova di tipo che riguardano sia i contatori elettromeccanici che i contatori statici per utilizzo sia in interno che in esterno.
Essa non è applicabile:
- ai contatori nei quali la tensione tra i terminali di connessione superi i 600 V;
- ai contatori portatili;
- ai contatori di riferimento.
Il superamento delle prove indicate garantisce agli apparati il funzionamento corretto in normali condizioni di lavoro. Per condizioni operative speciali potrebbero essere necessarie tipologie e/o livelli di prova particolari da concordare tra utilizzatore e fabbricante.

La presente Parte 1 della Norma EN 50470 deve essere utiizzata o con la Parte 2 o con la Parte 3, secondo il tipo di contatore cui si è interessati, per l'individuazione del quale si rimanda al sommario delle suddette Parti (EN 50470-2 e 50470-3).

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.
