This European Standard refers to particulate air filters for general ventilation. These filters are classified according to their measured performance in this test procedure.
This European Standard contains requirements that particulate air filters must meet. Explains test methods and test equipment to measure filter performance.
To obtain results for comparison and classification purposes, particulate air filters should be tested against two synthetic aerosols, a fine aerosol, for measurement of filtration efficiency as a function of particle size in the 0,2 µm to 3,0 particle size range.
This European Standard applies to air filters with an initial efficiency of less than 0,4% relative to 98 µm particles. The filters will be tested at an air flow rate between 0,24 m3/s (850 m3/h) and 1,5 m3/s (5400 m3/h).
Performance results obtained in accordance with this standard cannot be applied quantitatively alone to predict performance in service in terms of efficiency and life.
