High efficiency particulate air filters (HEPA and ULPA) - Part 4: Determining leakage of filter element (Scan method)

This standard applies to high efficiency air filters and ultra low penetration air filters (HEPA- and ULPA-filters) used in the field of ventilation and air conditionning and for technical processes, for example, for clean room technology or applications in the nuclear or pharmaceutical industry. It establisches a procedure for the determination of the efficiency on the basis of a particle counting method using a liquid test aerosol, and allows a standardized classification of these filters in terms of their efficiency.
