One of the important physical characteristics of glass is its strength. The biaxial flexural strength test is used for strength evaluation usually. The biaxial test offers several advantages over uniaxial test because it critically explores surface flaws – as it does not matter in which orientation the crack lies. However, it does minimize the volume or surface area investigated and also the edge effect. In the paper modification of strength testing process is suggested based on both ball-on-three-balls and ball-on-ring-of-balls principle. This work demonstrates that the biaxial flexure test can be used for the testing of glass.
