This European Standard refers particulate air filters for general ventilation. These filters are classified according to their performance. This European Standard contains requirements to be met by particulate air filters. It describes testing methods and the test rig for measuring the filter performance. The performance results obtained in accordance with this standard connot by themselfs be quantitatively applied to predict performance in service. In order to obtain results for comparison and classfication purposes, particulate air filters shall be tested against an atmospheric aerosol and a synthetic test aerosol. This European Standard applies to air filters which are to be tested between an airflow rate of 0,24 3/s (850 m3/h) and 1,39 m3/s (5000 m3/h) and have an initial atmospheric dust spot effciency lower than 98%.
