ISO/TS 10798:2011 establishes methods to characterize the morphology, and to identify the elemental composition of catalysts and other inorganic impurities in raw and purified single-wall carbon nanotube (SWCNT) powders and films, using scanning electron microscopy and energy dispersive X-ray spectrometry analysis.

The methods described in ISO/TS 10798:2011 for SWCNTs can also be applied to the analysis of multiwall carbon nanotubes (MWCNTs).
