Abstract
Methods of validating edge strength of a glass sheet are provided. The glass sheet includes a first surface, a second surface opposing the first surface, a thickness defined between the first surface and the second surface, and at least one edge including an edge surface. The first surface and the second surface intersect the edge surface of the at least one edge. The methods include a step (I) of noncontactually thermally loading the glass sheet to subject at least a portion of the at least one edge to a tensile stress. The methods also include a step (II) of determining whether the at least one edge has an edge strength below a predetermined level by detecting whether a resulting strength imperfection has originated in the glass sheet due to the noncontactual thermal loading of step (I).
