Characterization of Carbon Materials

IUPAC has approved a three-year project to collect a compilation of various national standards for characterization of carbon materials (ASTM, British Standards, AFNOR-France, DIN-Germany, JIS-Japan, ISO, etc.). Although largely similar, the national standards differ in details of determination of properties (e.g., true density, coefficient of thermal expansion, chemical composition, etc.) that are characteristic of given carbon materials or their precursors in production. Such differences often have a marked influence on the characteristic data. These differences frequently cause disagreement in international cooperation for commerce, and a comparison of the various standards can help to recognize the cause of diverging results. An earlier, similar compilation by W. S. Horton (PAC, Vol. 51, pp. 1561-1574, 1979) is outdated.

Comments and inquiries from the chemistry community are welcome and should be addressed to the Task Group Chairman, Prof. H.-P. Boehm, Department Chemie, Universität München, Butenandstrasse 5-13 (Haus D), D-81377 München, Germany, Fax: +49 89 2180 7492; E-mail: See for project description and update.
