Popis
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 3Â nm to 30Â nm. The testing methods in this document are limited to spherical or nearly-spherical particles to avoid uncertainties due to the particle shape.
