Resumen:
This International Standard refers to particulate air filters for general ventilation having an initial efficiency of less than 99 % with respect to 0,4 µm particles. Filters used in the ventilation of low-rise residential buildings or portable room-air cleaners are excluded from the scope of this standard. This standard describes the procedure to determine the gravimetric efficiency and the resistance to airflow for a given air cleaning device. After determination of the initial particle removal efficiency and the conditioned particle removal efficiency, the filter element is loaded with synthetic dust until its final test pressure drop is reached. The pressure drop curve versus the dust loading is recorded during the course of dust loading to determine the test dust holding capacity.
