ABSTRACT

This International Standard specifies the test equipment and test procedure for determining the filtration efficiency of flat sheet filter material in relation to airborne nanoparticles in the size range from 20 to 500 nm. The test methods specified in this International Standard are applicable only to particles with a spherical or nearly spherical shape in order to avoid uncertainties associated with determining the shape of particles.
