NF EN ISO 16890-3, X44-062-3 (09/2024)

ISO 16890-3:2016 specifies test equipment and test methods used to measure the gravimetric efficiency and air flow resistance of a general ventilation air filter. It is intended to be used in conjunction with ISO 16890-1, ISO 16890-2 and 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, 530 ft3/min) and 1.5 m3/s ( 5,400 m3/h, 3,178 ft3/min), referring to a test bench having a nominal frontal area of 610 mm × 610 mm (24 inch × 24 inch). ISO 16890 (all parts) concerns general ventilation filter elements having an ePM1 efficiency less than or equal to 99% and an ePM10 efficiency greater than 20%, when tested according to the procedures defined in ISO 16890 (all parts). ISO 16890 (all parts). Apart from these aerosol fractions, filter elements 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 of this part of ISO 16890. Performance results obtained in accordance with ISO 16890 (all parts) cannot be used quantitatively to predict in-service performance, with respect to efficiency and service life.
