This Technical Specification lists fundamental characteristics which are commonly determined for
nanoparticles in powder form. The Technical Specification prescribes specific measurement methods
for each of these characteristics.
This Technical Specification does not specify acceptable quantitative criteria for the characteristics
because they are subject to agreement between sellers, buyers, and regulators.
Excluded in this Technical Specification are characteristics specifically related to health, safety, and
environmental issues, as well as characteristics that pertain to specific applications of nanoparticles
in powder form.
