This pre-standard shall provide guidance on how the different properties of single-wall carbon nanotubes can be listed, represented and defined for industrial application in electronic products, and how they can be introduced in a bilateral detail specification between vendor and user. The pre-standard provides a blank detail specification for single-wall carbon nanotubes. Essential electrical properties and certain other common characteristics including dimensional, structural and mechanical properties of single-wall carbon nanotubes are compiled therein. The document provides a standardized format for detail specifications characterising essential basic properties of single-wall carbon nanotubes and also recommends suitable measurement methods. Single-wall carbon nanotubes with a chemical modification, dispersed into a solvent or tubes grown on a substrate are also included. Experiences shall be collected with this pre-standard with the purpose of integrating these into an International Standard at a later stage. The responsible committee is K 141 "Nanotechnologie" ("Nanotechnology") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
