International harmonization The US is represented at the technical committees (TCs) of the International Organization for Standardization (ISO) through technical advisory groups (TAGs) of the American National Standards Institute (ANSI). In 1994, ANSI named the ASTM as administrator of TAG-206 to represent the US at ISO’s TC206 on Fine (Advanced, Technical) Ceramics. In February 1997, a working group (WG9) on tensile beha￾vior of CFCCs was officially established as part of TC206, with the US serving as the convenor. At the first official E. Lara-Curzio, M.G.
