Fans — Determination of fan sound power levels under standardized laboratory conditions — Part 1: General overview

Ventilateurs — Détermination des niveaux de puissance acoustique des ventilateurs dans des conditions de laboratoire standardisées — Partie 1: Présentation générale

Abstract / scope

This document establishes principles for the determination of the acoustic performance of fans. In addition, this document can be used to determine the acoustic performance of fans combined with an ancillary device such as a roof cowl or damper or, where the fan is fitted with a silencer, the sound power resulting from the fan and silencer combination.
