Keywords: CFCCs; International harmonization; Test standards 1. Introduction Continuous fiber-reinforced ceramic composites (CFCCs) have been the focus of intensive developmental efforts over the last 15 years. These efforts have been driven to a large extent by the promise of substantial economic and environmental benefits if CFCCs are used in military and energy-related technologies, particularly at elevated temperatures [1]. Because the commercial diffusion and industrial acceptance of CFCCs can be hampered by lack of standard test methods, databases or design codes, initial standardization efforts concurrent with the development of these materials have focused on methods for the mechanical evaluation of test specimens, and on the drafting of design codes. 2. Test standards In the US, the American Society for Testing and Materi￾als (ASTM) has spearheaded the widespread introduction of standard test methods for advanced ceramics and ceramic composites. In 10 years since its inception, ASTM commit￾tee C28 on Advanced Ceramics has been responsible for the creation of over 25 standards. These standards range from clones of prior ASTM standards (with some new provisions) to complex, innovative documents tailored specifically to advanced ceramics [2]. Committee C28 of the ASTM is structured into eight subcommittees, as indicated in Fig. 1. A workshop organized by the National Institute for Stan￾dards and Technology (NIST) in February 1990 helped set the stage for the establishment of subcommittee C28.07 on ceramic matrix composites [3]. Since its establishment in 1991, subcommittee C28.07 has been responsible for forma￾lizing seven full consensus standard test methods for CFCCs and for drafting several other documents that are currently undergoing the ASTM’s internal balloting process. Table 1 lists the existing standards developed for CFCCs by subcommittee C28.07. In addition to its work of developing standards, subcommittee C28.07 has been responsible for informing the composites community of the progress in the standardization process through the organization of workshops and symposia.1 The work of subcommittee C28.07 has been organized around task groups, which are responsible for the prepara￾tion of drafts, and for the progress of these documents through the balloting and approval process at the subcom￾mittee, committee and society levels. Table 2 lists the task groups currently existing in C28.07.
