La presente Norma nazionale riguarda la verifica dei complessi di misura a corrente alternata, destinati alla misura dell’energia attiva in circuiti monofase e trifase, per fini commerciali o per accertamenti di carattere fiscale, e costituiti dall’insieme dei contatori, degli eventuali trasformatori di misura che li alimentano e dei relativi cavetti di connessione
La presente Norma non riguarda la costruzione, l’accettazione e il collaudo dei contatori nuovi per i quali valgono rispettivamente le Norme CEI 13-13, 38-1 e 38-2.
Essa inoltre non riguarda gli eventuali strumenti indicatori e registratori associati al complesso di misura, se non in quanto la loro presenza possa influire sulla precisione delle misure.
Nella Norma sono contenute le direttive generali da seguire per la verifica dei complessi di misura dell’energia attiva, sia all’atto dell’installazione, sia durante l’esercizio, e sono precisati i limiti di errore ammissibili per detti complessi in relazione alle caratteristiche degli apparecchi che li costituiscono e all’importanza delle misure ad essi affidati.

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.
