The methods of test in this standard apply to air control and distribution devices used in air distribution systems for commercial buildings. These devices provide control of air volume with or without temperature control by one or more of the following means and may or may not include a fan: a. fixed or adjustable vanes, b. pressure-dependent volume dampers or shutoff valves (including air induction nozzles and dampers), c. pressure-compensated volume dampers or shutoff valves (including air induction nozzles and dampers), d. heat exchange, e. ON/OFF fan control, or f. variable-speed fan control. This standard covers test methods for use in determining the following performance characteristics: a. sound power, b. temperature mixing and stratification, c. minimum operation pressure, d. air leakage, e. induced air, f. fan volume airflow, g. fan motor electrical power, and h. condensation. This standard does not cover individual control components nor those products covered in other ASH
