Air filters for general ventilation - Determination of the gravimetric efficiency and the air flow resistance versus the mass of test dust captured1 Scope This part of ISO 16890 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 ISO 168901, ISO 168902 and ISO 168904. 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
