This European Standard specifies the use of different metrics for the measurement of exposure by inhalation of NOAA during a basic assessment and a comprehensive assessment, respectively, as described in EN 17058 [1]. This document demonstrates the implications of choice of particle metric to express the exposure by inhalation to airborne NOAA, e. g. released from nanomaterials1) and present the principles of operation,
