Thi
14、s European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2010, and conflicting national standards shall be withdrawn at the latest by May 2010. Attention is drawn to the possibility that some of the eleme
15、nts of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1822-2:1998. It is dealing with the performance testing of efficient particulate air filters (EPA), high efficiency pa
16、rticulate air filters (HEPA) and ultra low penetration air filters (ULPA) at the manufacturers site. EN 1822, High efficiency air filters (EPA, HEPA and ULPA), consists of the following parts: Part 1: Classification, performance testing, marking Part 2: Aerosol production, measuring equipment, parti
17、cle counting statistics Part 3: Testing flat sheet filter media Part 4: Determining leakage of filter elements (scan method) Part 5 : Determining the efficiency of filter elements This European Standard is based on particle counting methods which actually cover most needs of different applications.
18、The difference between this European Standard and its previous edition lies in the addition of: an alternative test method for using a solid, instead of a liquid, test aerosol; a method for testing and classification of filters made out of membrane type filter media; a method for testing and classif
19、ication filters made out of synthetic fibre media; and an alternative method for leak testing of group H filters with other than panel shape. Beside that, various editorial corrections have been implemented. According to the CEN/CENELEC Internal Regulations, the national standards organizations of t

The difference between this European Standard and p
22、revious national standards lies in the technique used for the determination of the integral efficiency. Instead of mass relationships, this technique is based on particle counting at the most penetrating particle size (MPPS), which is for micro-glass filter mediums usually in the range of 0,12 m to
