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

This European Standard provides guidelines to assist workplace exposure by inhalation of nano-objects and their aggregates and agglomerates (NOAA). It guidance on the sampling and measurement strategies to adopt and methods for data evaluation. While the focus of this document is on the assessment of nano-objects, the approach is also applicable for to the aggregate aggregates associated and agglomerates, i.e. NOAA, and particles released from nanocomposites and nano-enabled products.
