La presente Norma specifica le prescrizioni generali di prestazione di tutti i relè elettrici di misura e dei dispositivi di protezione utilizzati nei campi elettrotecnici. Esclude i relè utilizzati nei seguenti campi elettrotecnici: telefonia, telegrafia, segnalazione e blocco nei sistemi ferroviari. Per applicazioni speciali (marina, aeronautica, atmosfere esplosive, computer ecc.), può essere ampliata mediante prescrizioni speciali. I relè progettati per soddisfare le prescrizioni preparate da altri organismi internazionali di normalizzazione (telecomunicazioni, ferrovie ecc.) devono essere conformi alla presente Norma quando sono utilizzati nei campi elettrotecnici coperti dalla IEC, diversi da quelli esclusi sopra. Le prescrizioni si applicano solo ai relè nuovi. Tutte le prove della presente Norma sono prove di tipo se non diversamente dichiarato. Scopo della presente Norma è stabilire: le definizioni dei termini utilizzati; i valori nominali relativi alle grandezze di alimentazione e di influenza; le prescrizioni relative alla precisione, alle prestazioni termica e meccanica; i metodi di prova; i dati di targa e le indicazioni.
La presente Norma costituisce la ristampa senza modifiche, secondo il nuovo progetto di veste editoriale, della Norma pari numero ed edizione (Fascicolo 2457).
La presente Norma é annullata e sostituita dalla Nuova Norma, CEI EN 60255-1:2010-07 (CEI 95-21), tuttavia rimane applicabile fino al 1-12-2012.

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.
