High efficiency air filters (EPA, HEPA and ULPA) -- Testing flat sheet filter media
This European Standard applies to high efficiency particulate air filters and ultra low penetration air filters (EPA, HEPA and ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or 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 applies to testing sheet filter media used in high efficiency air filters.
The procedure includes methods, test assemblies and conditions for carrying out the test, and the basis for calculating results.
