This document specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation.
It is intended to be used in conjunction with ISO16890‑1, ISO16890‑3 and ISO16890‑4.
The test method described in this document is applicable for air flow rates between 0,25m3/s (900m3/h, 530ft3/min) and 1,5m3/s (5400m3/h, 3178ft3/min), referring to a test rig with a nominal face area of 610mm×610mm (24.0inches × 24.0inches).
This document refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99% and an ePM10 efficiency greater than 20% when tested as per the procedures defined within the ISO16890 series.
NOTE The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20% since it is very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure.
This document is not applicable to filter elements used in portable room-air cleaners.
