ABSTRACT

This document specifies the test instruments and procedures for the determination of the Filtration efficiency of planar filter media versus airborne nanoparticles in the range 3nm to 30nm. The test methods described in this document are limited to spherical or quasi-spherical particles in order to avoid uncertainties related to the shape of the particles. This document also gives the measurement uncertainties and the presentation of the results.
