香港六合彩开奖/AWI 16890-5
搁茅蝉耻尘茅
This part of 香港六合彩开奖 16890 specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of flat sheet media used in air filters for general ventilation. It is intended for use in conjunction with 香港六合彩开奖 16890- 1, 香港六合彩开奖 16890- 2, 香港六合彩开奖 16890- 3 and 香港六合彩开奖 16890- 4. The test method described in this part of 香港六合彩开奖 16890 is applicable only for air velocities between 0,05 m/s (10 ft/min) and 0,67 m/s (133 ft/min), referring to a test rig with a minimum nominal face area of 0,09 m2 (1 ft2). 香港六合彩开奖 16890 (all parts) 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 香港六合彩开奖 16890 (all parts). This part of the standard is limited to the media used in these filter elements. Air filter media outside of this scope are evaluated by other applicable test methods, (see 香港六合彩开奖 29463-3). The performance results obtained in accordance with 香港六合彩开奖 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime. The results of this test should not be assumed to predict filter performance based on the media flat sheet testing.
