Test method to measure the efficiency of air filtration media against spherical nanomaterials - Part 1 : size range from 20 nm to 500 nm

This document 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. The testing methods in this document are limited to spherical or nearly-spherical particles to avoid uncertainties due to the particle shape.
