EN ISO 16890-3 specifies the test equipment and the test methods used for measuring the gravimetric efficiency and resistance to air flow of air filter for general ventilation. It is intended for use in conjunction with EN ISO 16890-1, EN ISO 16890-2 and EN ISO 16890-4. The test method described in this part of ISO 16890 is applicable for air flow rates between 0,25 m3/s (900 m3/h) and 1,5 m3/s (5400 m3/h), referring to a test rig with a nominal face area of 610 mm x 610 mm. EN ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an initial efficiency less than or equal to 99 % with respect to ePM1 aerosol fraction and greater than 20 % with respect to ePM10 aerosol fraction when tested per the procedures defined within EN ISO 16890-1 to EN ISO 16890-4. Air filter elements outside of this aerosol fraction are evaluated by other applicable test methods. See ISO 29463 (all parts). Filter elements used in portable room-air cleaners are excluded from the scope. The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime.
