Particulate air filters for general ventilation. Requirements, testing, marking

NEN-EN 779-1994 发布历史

This European Standard refers to particulate air filters for genera! 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 cannot by themselves be quantitatively appüed to predict performance in service. 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 European 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 %.
