Detalles

This document specifies methods of determining nanoparticle size and shape distributions by acquiring

and evaluating scanning electron microscope images and by obtaining and reporting accurate results.

NOTE 1 This document applies to particles with a lower size limit that depends on the required uncertainty

and on the suitable performance of the SEM, which is to be proven first -according to the requirements described

in this document.

NOTE 2 This document applies also to SEM-based size and shape measurements of larger than nanoscale

particles.
