The tensile strength of a commercial, high alumina body was investigated by using hydraulically expanded cylindrical test specimens. Results were evaluated with respect to loading rate, surface finish, and microstructure. At various loading rates, uniform tensile strength data coefficients of variation of less than 7.6 percent were obtained in testing groups of specimens having the same fabrication history, while the differences in tensile strength between individual groups of specimens gave a measure of the over-all extent to which uncontrollable fabrication variables affect the tensile strength of alumina bodies.
