The strength of many brittle ceramics reflects the flaws present in the material and the intrinsic fracture toughness. Interpretation of strength- test results for monolithic, brittle advanced ceramics requires fractographic analysis whether mechanical testing has done for quality control, materials development, or design purposes. Progress is presented on an effort to develop a standard practice for fractographic analysis of laboratory strength-test specimens. The primary goal is to encourage fractography as a complement to mechanical testing. Procedures will be developed with regard to inspection techniques, sampling criteria and reporting practices. The standard practice is in a formative state and the purpose of this report is to present its framework and solicit recommendations and comments.
