ABSTRACT
This document specifies the use of different metrics for the measurement of the inhalation exposure of NOAA during a basic assessment and a full assessment, respectively, as described in NF EN 17058. This document demonstrates the consequences of choosing a particle metric to express inhalation exposure to airborne NOAAs, for example from the suspension of nanomaterials, and presents the operating principles, advantages and disadvantages of various techniques for measuring the various parameters of aerosols.
