Scope: What is ISO 21083-1 about? ISO 21083 discusses the efficiency of air filtration media against spherical nanomaterials. ISO 21083-1 is the first part of the ISO 21083 multi-series. ISO 21083-1 specifies the testing instruments and procedure for determining the fractional filtration efficiencies of flat sheet filter medium against airborne nanoparticles in the range of 20 nm to 500 nm. Nanoparticles, referring to particles with at least one dimension below 100 nm, generally have higher mobility than larger particles. Because of their higher mobility and larger specific surface area, available for surface chemical reactions, they can pose a more serious health risk than larger particles. Thus, particulate air pollution with large concentrations of nanoparticles can result in an increasingly adverse effect on human health and an increased mortality Who is ISO 21083-1 for ? ISO 21083-1 on measuring the efficiency of air filtration media against spherical nanomaterials is useful for: Air filter manufacturers Pollution control bodies Health and safety bodies Quality control personnel Why should you use ISO 21083-1
