Laboratory Test Method for Assessing the Performance of Gas-Phase Air-Cleaning Systems: Loose Granular Media
This standard prescribes a small-scale laboratory test method for measuring the contaminant removal efficiency of loose granular sorptive media used in gas-phase air-cleaning equipment as installed (in a test apparatus) in an air stream and challenged with test gases under steady-state conditions. This test is conducted at elevated gas challenge concentrations(relative to ventilation applications) and therefore should be used to compare media rather than directly predict performance in any particular application.
