DESCRIPTION
UNE CEN ISO/TS 21083-2:2019
This document specifies the testing instruments and procedure for determining the filtration efficiencies of flat sheet filter media against airborne nanoparticles in the 3 nm to 30 nm range. The testing methods in this document are limited to spherical or nearly-spherical particles to avoid complications due to the particle shape.
