- Scope
- This European Standard applies to efficient particulate air filters (EPA); high efficiency particulate air filters (HEPA) and ultra low penetration air filters (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 part of the EN 1822 series deals with measuring the efficiency of filter elements; specifying the conditions and procedures for carrying out tests; describing a specimen test apparatus and its components; and including the method for evaluating test results.
