Annotation of standard text ČSN EN ISO 19749 (012008):

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
