This European Standard applies to high effciency particulate air filters and ultra low penetration air filters (HEPA and ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for clean room technology or applications in the nuclear and pharmaceutical industry. It establishes 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. This European Standard describes the measuring instrurnents and aerosol generators used in the Course of this testing. With regard to particle counting it specifies the statistical basis for the evaluation of counts with only small numbers of counted events.
