1998EN ISO 5135:1998 Acoustics - Determination of sound power levels of noise fromair-terminal devices, air-terminal units, dampers and valves by measurement in a reverberation room
EN ISO 5135:1998 Acoustics - Determination of sound power levels of noise fromair-terminal devices, air-terminal units, dampers and valves by measurement in a reverberation room has been changed from EN 25135:1991 Acoustic; 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 (identical with ISO 5135:1984).
