- Scope
- 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.
