TECHNICAL OFFICER Per.Ind. ANDREA NAFI

Scope of application

Norme per apparecchiature di manovra e di comando ad alta tensione, superiore a 1 kV c.a. e 1,5 kV c.c., e per assiemi di apparecchi con isolamento in gas, combinazioni di di una o piĆ¹ parti di apparecchiature a tensione superiore a 1 kV c.a., con gli associati dispositivi di comando, misura, segnalazione, protezione, regolazione ecc. Richieste di deviazioni nazionali, quando necessario, alle norme europee in caso di apparecchiature che comportano involucri in pressione per l'adeguamento ai regolamenti vigenti in Italia.

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.
