ISO 29463 establishes a procedure for the determination of the ,efficiency, of all ,filters, on the basis of a particle counting ,method, using a liquid (or alternatively a solid) ,test, aerosol, and allows a standardized classification of these ,filters, in terms of their ,efficiency,, both local and overall ,efficiency,, which actually covers most needs of different applications.
Under the new ,particulate filter, tests, NIOSH will certify three classes of ,filters,, N-, R-, and P-series, with three levels of ,filter efficiency,, 95%, 99%, and 99.97%, in each class. All ,filter, tests will employ the most penetrating aerosol size, 0.3 µm aerodynamic mass median diameter.
