La presente Norma fornisce le prescrizioni per l’uso di denominazioni e simboli letterali applicabili a grandezze ed unità di misura riferite alle macchine elettriche rotanti.
La presente CEI EN 60027-4 costituisce completa revisione tecnica della CEI 24-2:1997.
In particolare, nella presente Norma sono evidenziati, in aggiunta, i riferimenti all’IEV (Vocabolario Elettrotecnico Internazionale - VEI).
Questa Norma viene pubblicata dal CEI in una prima fase nella sola lingua inglese, per consentirne l'immediato utilizzo da parte degli utenti interessati, nel rispetto della data di pubblicazione fissata dagli Enti Normatori internazionali.
Successivamente il CEI pubblicherà, in un nuovo fascicolo - ma come medesima edizione - la stessa Norma in versione italiano-inglese; tale nuova versione avrà la stessa validità della presente.
La presente Norma recepisce il testo originale inglese della Pubblicazione IEC e pertanto consta delle sole pagine dispari.

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.
