DESCRIPTION
BS EN ISO 5135:2020
This standard BS EN ISO 5135:2020 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 is classified in these ICS categories:
- 17.140.20 Noise emitted by machines and equipment
- 91.140.30 Ventilation and air-conditioning systems
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.
