ASTM C1326 covers the determination of tensile strength under uniaxial loading of monolithic advanced ceramics at ambient temperatures. ASTM C1326 addresses various suggested test specimen geometries as listed in the appendix. Additionally, it covers test specimen fabrication methods, testing modes, testing rates, allowable bending, and data collection and reporting procedures. ASTM C1326 primarily applies to advanced ceramics that exhibit isotropic, homogeneous, continuous behaviour. While intended for monolithic advanced ceramics, certain whisker- or particle-reinforced composite ceramics, as well as certain discontinuous fibre-reinforced composite ceramics, may also meet these macroscopic behaviour assumptions.
ASTM C1326 Test Method
| Universal Testing Machine | The ASTM C1273 test method uses a universal testing machine (UTM) to apply tensile stress to the specimen until it breaks. An extensometer monitors changes in the specimen’s length. The specimen is shaped like a round rod with large shoulders on each end for gripping by the UTM. |
| Measurements of Changing Length of the Specimen | The machine measures changes in gauge length as it pulls the specimen. The test is conducted in a controlled environment to minimize the influence of other factors like temperature and contaminants. |
