Apparatus and method for testing a sheet of brittle material comprising the steps of measuring one or more edge features of a sheet of brittle material, imparting a bend to the sheet of brittle material and producing relative motion between the sheet and the bend such that the bend traverses the sheet. A stress can be induced in the sheet as a function of the relative motion and imparted bend, wherein the induced stress corresponds to a predetermined strength value, and the measured one or more edge features can be correlated with the strength value.

Edge strength testing methods and apparatuses

A method includes introducing light into a glass article such that at least a portion of the introduced light is emitted from an edge of the glass article. The light emitted from an edge of the glass article is detected. An intensity profile of the emitted light is an intensity of the emitted light as a function of axial position. A first intensity boundary of the intensity profile and a second intensity boundary of the intensity profile are determined. A thickness of a layer of the glass article is determined based on an axial distance between the first intensity boundary and the second intensity boundary.
