ASTM C158 testing covers the determination fo the modulus of rupture in bending of glass and glass-ceramics.
This procedure has methods for testing modulus of rupture of flat glass and comparative testing for modulus of rupture of glass and glass-ceramics.
Test specimens are inserted into the four-point bend fixture and loaded at a constant rate. A deflectometer is placed at the center of the specimen in order to measure deflection and strain at center-span throughout the test.
The calculated modulus of rupture is considered a valid measure of tensile strength.
