EN 1822-3:1998

EN 1822-3:1998 is a standard published by the European Committee for Standardization (CEN). Its full title is "High efficiency air filters (HEPA and ULPA) - Part 3: Testing flat sheet filter media". This standard covers: This European Standard applies to high efficiency particulate air filters and ultra low penetration air filters (HEPA and ULPA) used in the field of ventilation and air conditioning and for technical process, e.g. for clean room technology or applications in the nuclear and pharmaceutical industry. It established a procedure for the determination of 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.
