ASTM C1211 Flexural Testing for Ceramics

ASTM C1211 measures the flexural strength of advanced ceramics at elevated temperatures. Flexure stress is computed using simple beam theory assuming the material is isotropic, homogeneous, the moduli of tension and compression are identical, and it is linear elastic. Use a three-point and four-point flexure tests for this standard.

ASTM C1211

For ASTM C1211, use rectangular cross section specimens. The flexural strength of the specimens can be influenced by outside factors. Remember to consider the testing rate, test environment, specimen size, specimen preparation, and test fixtures.

This method determines the flexural strength at elevated temperature and ambient environmental conditions at a nominal, moderately fast testing rate. The flexural strength under these conditions is not always the inert flexural strength. Flexure strength at elevated temperature may be strongly dependent on testing rate, a consequence of creep, stress corrosion, or slow crack growth.

A universal testing machine can be used alongside a furnace to test your ceramic. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM C1211.
