Nanotechnologies. Single-wall carbon nanotubes. Characterization by scanning electron microscopy and energy dispersive X-ray spectrometry

This standard applies to materials containing single-wall carbon nanotubes (SWCNTs) and specifies scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometry (EDX) methods for determining the chemical composition of catalysts and inorganic impurities. This standard applies to purified nanomaterials and as-manufactured nanomaterials. The methods specified in this standard are applicable to nanomaterials containing multi-wall carbon nanotubes (MWCNTs).
