La presente Norma specifica i metodi di prova per la determinazione del livello di potenza acustica delle macchine elettriche rotanti. La Norma specifica il livello massimo di potenza acustica ponderata A per le prove di accettazione in fabbrica delle macchine elettriche rotanti conformi alla IEC 60034-1, con modi di raffreddamento secondo la IEC 60034-6, gradi di protezione secondo la IEC 60034-5 ed aventi le seguenti caratteristiche: progetto normale, in corrente alternata o in corrente continua, senza ulteriori speciali modifiche elettriche, meccaniche o acustiche intese a ridurre il livello di potenza sonora, potenza assegnata da 1 kW (o kVA) fino a 5500 kW (o kVA) compresi, e velocità non superiore a 3750 g/min. Si ritengono esclusi i motori in corrente alternata alimentati da convertitori, per i quali ci si riferisce alla IEC 60034-17. La presente Norma riporta il testo in inglese e italiano della Norma europea EN 60034-9; rispetto al precedente fascicolo n. 7738E di luglio 2005, essa contiene la traduzione completa della Norma EN sopra indicata. La presente Norma è annullata e sostituita dalla Nuova Edizione CEI EN IEC 60034-9 (2-24), tuttavia rimane applicabile fino al 30/11/2027.

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.
