La presente Norma specifica le prescrizioni, per gli apparecchi di prova, applicate alla verifica dell'efficacia dei dispositivi di controllo della corrente residua (RCM) di tipo A e di tipo B, che sono già installati nei sistemi di distribuzione. Tali apparecchi di prova possono essere utilizzati in qualsiasi tipo di rete con sistemi TN, TT o IT. L'apparecchiatura di prova può essere utilizzata anche per prove RCM a discriminazione direzionale nei sistemi IT. La presente edizione sostituisce la precedente e costituisce una revisione tecnica, che include le seguenti modifiche tecniche significative rispetto alla precedente:
a) titolo del documento, modificato per includere tutti i tipi di RCM;
b) termini allineati alla IEC 60050;
c) aggiunta di requisiti per testare nuovi tipi di RCM;
d) spostamento dei requisiti per RCM di tipo B dall'ex Allegato A al corpo principale;
e) allineamento della struttura con quella di tutta la serie IEC 61557.
La Norma in oggetto sostituisce completamente la Norma CEI EN 61557-11:2013-11, che rimane applicabile fino al 06-04-2025.
La presente Norma riporta la traduzione completa della EN IEC 61557-11; la versione inglese è riportata nel fascicolo 18953E di novembre 2022.

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.
