ASTM C158-Standard test methods for strength of glass by flexure

These test methods cover the determination of the modulus of rupture in bending of glass and glass-ceramic. It is applicable to annealed and prestressed glasses and glass-ceramics available in varied forms. There are two test methods. Test method A is a test for modulus of rupture of flat glass. Test method B is a comparative test for modulus of rupture of glass and glass-ceramics. The test methods used shall be determined by the purpose of the test and geometric characteristics of specimens representative of the material

Equipment requirement:
It needs a universal testing machine to supply sufficiently adjustable to give the required uniform rate of increase of stress. For more information, please contact our engineers.
