Workplace exposure - Assessment of exposure by inhalation of nano-objects and their aggregates and agglomerates

This European Standard describes different levels of assessment of inhalation exposure to nano-objects and their agglomerates and aggregates (NOAA), as well as the evaluation of the results either as stand-alone assessment or embedded in a tiered approach framework. While the focus of this European Standard is on the assessment of nano-objects, the approach is applicable for exposure to the associated agglomerates and aggregates, i.e. NOAA, and particles released from nano composites and nano-enabled products.
