Nanotechnologies. Considerations for in vitro studies of airborne nano‐objects and their aggregates and agglomerates (NOAA) Ingestion-build-63114 Annex D (normative) Requirements forWhat is PD ISO TR 21624 about? PD ISO TR 21624 discusses in vitro studies of airborne nanoobjects and their aggregates and agglomerates (NOAA) for nanotechnologies. PD ISO TR 21624 provides guidance practices regarding the systems available for exposure and assessment of nano objects and their aggregates and agglomerates (NOAA) for in vitro air exposure studies. PD ISO TR 21624 provides an overview of the various exposure systems and in vitro cell
