Workplace exposure - Counting rules for the characterization of airborne nano-objects and their agglomerates and aggregates for scanning electron microscopy (SEM) and transmission electron microscopy (TEM) cen:proj:72093

Scope

This European Standard gives guidelines on counting rules and criteria for the determination of the concentration and characterisation (e.g. classification of structures, chemical composition and morphology) of airborne NOAA using electron microscopic methods (SEM and TEM), especially for nanofibers and platelets (e.g. carbon nanotubes and graphene nanoplatelets)
