La presente Norma tratta delle tecniche di misura del rumore acustico prodotto dalle turbine eoliche.
La Norma presenta metodi di misura appropriati per la valuazione del rumore acustico in prossimità della macchina, per evitare errori dovuti alla propagazione del suono, ma abbastanza lontano da permettere di trascurare le dimensioni finite della sorgente.
Tali metodi sono volti a facilitare la caratterizzazione del rumore prodotto da un aerogeneratore in relazione a una gamma di velocità e direzioni del vento. La normalizzazione delle procedure di misura facilita anche il confronto tra aerogeneratori diversi.
Le metodologie indicate consentono di caratterizzare in modo coerente e accurato le emissioni di rumore di un singolo aerogeneratore.
Rispetto alla precedente edizione, di cui costituisce revisione tecnica, sono stati introdotti nella Norma nuovi principi per le procedure di riduzione dei dati.
La Norma in oggetto sostituisce completamente la Norma CEI EN 61400-11:2004-01, che rimane applicabile fino al 12-12-2015.
La presente Norma riporta il testo in inglese e italiano della EN 61400-11; rispetto al precedente fascicolo n. 12988E di luglio 2013, essa contiene la traduzione completa della EN sopra indicata.

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.
