Scope of application
Il Comitato Tecnico si occupa dell'attività normativa relativa alle apparecchiature e ai quadri protetti per uso industriale e commerciale per tensioni inferiori a 1 kV in c.a. e a 1,5 kV in c.c. (bassa tensione). Il campo di attività comprende gli apparecchi - sia elettromeccanici sia a semiconduttori - separati, con o senza involucro, e le loro combinazioni in unità funzionali.
Structure
Il CT 121 coordina i seguenti SottoComitati:
- SC 121A - Apparecchiature a bassa tensione
- SC 121B - Quadri protetti per bassa tensione.
Work Program
Le norme del CT 121 sono prodotte dai suoi SottoComitati. Il CT 121 ha direttamente pubblicato due documenti di carattere generale relativi agli aspetti ambientali e all’efficienza energetica dei prodotti.

INTERNATIONAL Related Committees - IEC
This Committee contributes, with the creation of standards, to the following themes
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.
