ASTM C1273 – 18 : Standard Test Method for Tensile Strength of Monolithic Advanced Ceramics at Ambient Temperatures
This test method covers the determination of tensile strength under uniaxial loading of monolithic advanced ceramics at ambient temperatures.
This test method addresses, but is not restricted to, various suggested test specimen geometries as listed in the appendixes.
In addition, test specimen fabrication methods, testing modes (force, displacement, or strain control), testing rates (force rate, stress rate, displacement rate, or strain rate), allowable bending, and data collection and reporting procedures are addressed. Note that tensile strength as used in this test method refers to the tensile strength obtained under uniaxial loading.
This test method applies primarily to advanced ceramics that macroscopically exhibit isotropic, homogeneous, continuous behavior.
While this test method applies primarily to monolithic advanced ceramics, certain whisker- or particle-reinforced composite ceramics as well as certain discontinuous fiber-reinforced composite ceramics may also meet these macroscopic behavior assumptions.
Generally, continuous fiber ceramic composites (CFCCs) do not macroscopically exhibit isotropic, homogeneous, continuous behavior and application of this practice to these materials is not recommended.
