There are currently significant differences in glass strength information presented by major United States glass manufacturers. These differences have caused considerable confusion among glass designers. Several years ago a glass failure prediction model was developed in an effort to provide a mechanism for restoring continuity to the glass design process. This failure prediction model allows the probability of failure of window glass to be specified in terms of surface flaw parameters and the stresses induced by lateral loads. For the past several years, a task group within ASTM has focused on developing a new set of glass design charts based on the glass failure prediction model. The result of this effort is a "Practice to Determine the Minimum Thickness of Annealed Glass Required to Resist a Specified Load." The proposed practice presents a method for relating the probability of failure of a rectangular annealed glass plate subjected to a 60 second duration design load. This new ASTM practice is currently in the ASTM ballot process.
