適用范圍：This International Standard provides guidelines for the determination of number concentration and the size distribution of ultrafine aerosols and nanoaerosols by use of mobility particle sizers (also called differential mobility analysers). Only the particle fraction of the aerosol is considered. For ultrafine aerosols and nanoaerosols, exposure metrics such as the number and surface area concentration are important.This International Standard also gives guidelines for the determination of workplace exposure to ultrafine aerosols and nanoaerosols.
