Nanotechnologies - Measurements of particle size and shape distributions by scanning electron microscopy (ISO 19749:2021)
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.*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.*This document applies also to SEM-based size and shape measurements of larger than nanoscale particles.
