ABSTRACT
This International Standard 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 1This International Standard applies to particles with a lower size limit that depends on the required uncertainty and on the suitable performance of the SEM, which must be proven first -according to the requirements described in this document.NOTE 2This International Standard applies also to SEM-based size and shape measurements of larger than nanoscale particles.
