Pages: 28
Issue Num.:  16993
Commitee: CEI-CT109
Questa Norma si applica ad assiemi protetti dall’inquinamento mediante l’uso di rivestimenti, riempimenti o stampaggi, consentendo quindi una riduzione delle distanze di isolamento in aria e delle distanze di isolamento superficiali descritte nella IEC 60664-1.
La Norma descrive le prescrizioni e le procedure di prova per due metodi di protezione:
- la protezione di tipo 1 migliora il microambiente delle parti protette;
- la protezione di tipo 2 è considerata analoga all’isolamento solido.
Le modifiche tecniche più significative di questa nuova edizione rispetto alla precedente sono le seguenti: informazioni aggiuntive riguardanti l’interpolazione e la prova di graffiatura che si applica solo per la protezione di tipo 2.
Questa Norma è una pubblicazione fondamentale di sicurezza in accordo con la Guida IEC 104.
La presente Norma sostituisce completamente la Norma CEI EN 60664-3:2004-02 che rimane applicabile fino al 16-06-2020.
La presente Norma riporta la traduzione completa della EN 60664-3; la versione inglese è riportata nel fascicolo 15933E di dicembre 2017.

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.
