DESCRIPTION

PD CEN ISO/TS 21083-2:2019


This standard PD CEN ISO/TS 21083-2:2019 Test method to measure the efficiency of air filtration media against spherical nanomaterials is classified in these ICS categories:
  • 91.140.30 Ventilation and air-conditioning systems

This document specifies the testing instruments and procedure for determining the filtration efficiencies of flat sheet filter media against airborne nanoparticles in the range of 3 nm to 30 nm. The testing methods in this document are limited to spherical or nearly-spherical particles to avoid uncertainties due to the particle shape.
