Laboratory Test Method for Assessing the Performance of Gas-Phase Air-Cleaning Systems: Air-Cleaning Devices
This standard prescribes a full-scale laboratory test method for measuring the performance of in-duct sorptive media gas-phase air-cleaning devices. In this context, “sorptive media” are defined as the active agent of the air cleaner, whether granular or sheet or pleated, that operate by adsorbing and/or chemically reacting with contaminant gases. This test is conducted under steady-state conditions at elevated gas challenge concentrations (relative to ventilation applications) and, therefore, should be used to compare devices rather than directly predict performance in any particular application.
