Defines requirements for acoustic testing in reverberation rooms of the type of equipment listed under clause 1. It is based on the use of ISO 3741 and ISO 3742, which describe the acoustic test facilities, instrumentation and procedures to be used for precision grade determination of sound power levels in octave or one-third octave bands of a noise source having a volume preferable less than 1% of the volume of the reverberation room. This International Standard establishes general rules for the acoustic testing of air terminal devices, high/low velocity/pressure assemblies and dampers and valves used in air diffusion and air distribution systems as defined in ISO 3258 in order to determine sound power levels as defined in ISO 3740. This International Standard is applicable to equipment operating under steady state conditions.
