- Scope
- 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 dif-fusion 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.
