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 airstream 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.
This standard defines methods of calculating and reporting
results obtained from the test data and establishes a results reporting system that can be applied to loose granular media covered by this standard.
This standard does not apply to
a. bonded carbon panels, beaded activated carbon, carbon
cloths, absorbent-loaded nonwovens, dry-process carbon
composites, or similar products or
b. particulate removal equipment.
