| Resumen: | This standard specifies the testing instruments and procedure for determining the particle size specific fractional filtration efficiency of flat sheet filter media against airborne nanoparticles in the 20 - 500 nm range. The testing methods in this document are limited to the use of spherical or nearly-spherical particles to avoid uncertainties due to the particle shape. |
