EN ISO 28439:2011 Workplace atmospheres - Characterization of ultrafine aerosols/nanoaerosols - Determination of the size distribution and number concentration using differential electrical mobility analysing systems (ISO 28439:2011)
This International Standard provides guidelines for the determination of the number concentration and sizedistribution of ultrafine aerosols and nanoaerosols by use of mobility particle sizers (also called differentialmobility analysers). Only the particle fraction of the aerosol is considered. For ultrafine aerosols andnanoaerosols, exposure metrics such as the number and surface area concentration are important.
