Standard Cancelled

Acoustics. Determination of sound power levels of noise from air terminal devices, high/low velocity/pressure assemblies, dampers and valves by measurement in a reverberation room.

La présente norme définit les conditions requises pour l'essai acoustique en salle réverbérante du type d'équipement spécifié dans l'article 1. Elle est basée sur l'application des normes NF ISO 3741 (S 31-022) et NF ISO 3742 (S 31-023) qui décrivent les dispositifs d'essai acoustique, l'équipement de mesurage et les procédures à employer pour la détermination en laboratoire des niveaux de puissance acoustique en bandes d'octave ou de tiers d'octave d'une source de bruit dont le volume est, de préférence, inférieur à 1% du volume de la salle réverbérante.

Acoustics - Determination of sound power levels of noise from air-terminal devices, air-terminal units, dampers and valves by measurement in a reverberation test room

This document establishes general rules for the acoustic testing of air-terminal devices, air-terminal units, dampers and valves used in air diffusion and air distribution systems in order to determine sound power levels as defined in ISO 3741.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
