Test method to measure the efficiency of air filtration media against spherical nanomaterials - Size range from 20 nm to 500 nmWhat is ISO 21083 1 about? ISO 21083 discusses the efficiency of air filtration media against spherical nanomaterials. ISO 21083 1 is the first part of the ISO 21083 multi series. ISO 21083 1 specifies the testing instruments and procedure for determining the fractional filtration efficiencies of flat sheet filter medium against airborne nanoparticles in the range of 20 nm to 500 nm. Nanoparticles, referring to particles with at least one dimension
