AASHTO T 97-17

This test method covers determination of the flexural strength of concrete by the use of a simple beam with third-point loading.

The values stated in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

Note—For methods of molding concrete specimens, see AASHTO T 23 and R 39.
