This European Standard provides guidelines for the assessment of inhalation exposure to nano-objects and their aggregates and agglomerates (NOAA) in workplaces. It provides guidance on the sampling and measurement strategies to be adopted and methods for data evaluation. While this document focuses mainly on the assessment of nano-objects, the approach described also applies to the exposure to their associated aggregates and agglomerates, ie NOAA, and particles released from nanocomposites and nano-object products.
