High efficiency particulate air filters (HEPA and ULPA) - Part 5: Determining the efficiency of filter element
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 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.
Part 5 of the standard 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 the test results.
Diese Europäische Norm gilt für Schwebstoffilter (HEPA) und Hochleistungs-Schwebstoffilter (ULPA) im Bereich der Raum- und Prozesslufttechnik, z.B. in der Reinraumtechnik, oder Anwendungen in der Nuklear- und pharmazeutischen Insutrie.
