In order to obtain results for comparison and classification purposes, particulate air filters shall be tested against an atmospheric aerosol and a synthetic test aerosol. This standard applies to air filters which are to be tested between an airflow rate of 0,24 m3/S (850 m3/h and 1,39 m3/s (5000 m3/h) and have an initial atmospheric dust spot efficiency lower than 98%.
