La presente Norma specifica i requisiti generali applicabili alle apparecchiature di misura e monitoraggio per la verifica della sicurezza elettrica nei sistemi di distribuzione a bassa tensione con tensioni nominali fino a 1 000 V in c.a. e 1 500 V in c.c. Altre parti della serie CEI EN 61557 possono specificare requisiti aggiuntivi. Questa edizione costituisce una revisione della precedente e include le seguenti modifiche tecniche significative:
a) aggiornamento della terminologia alla IEC 60050;
b) stima dell'incertezza rivista secondo le equazioni di cui al punto 4.2 della Guida ISO/IEC 98-3:2008 (GUM);
c) riferimenti aggiornati per i requisiti di sicurezza ed EMC;
d) riferimenti aggiornati per la marcatura e le istruzioni operative;
e) riferimenti aggiornati per le prove di sicurezza ed EMC;
f) l'Allegato A contiene chiarimenti relativi all’incertezza;
g) l'Allegato B riguarda gli aspetti ambientali.
La Norma in oggetto sostituisce completamente la Norma CEI EN 61557-1:2008-07, che rimane applicabile fino al 10-11-2024.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.

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.
