What is ISO 21363 about?

ISO 21363 discusses measurements of particle size and shape distributions by transmission electron microscopy for nanotechnologies. ISO 21363 outlines how to capture, measure and analyse transmission electron microscopy images to obtain particle size and shape distributions in the nanoscale. ISO 21363 broadly is applicable to nano-objects as well as to particles with sizes larger than   100 nm. The exact working range of the method depends on the required uncertainty and on the performance of the transmission electron microscope. These elements can be evaluated according to the requirements described in this document.
