ASTM E1300-24 is the Standard Practice for Determining Load Resistance of Glass in Buildings. It provides procedures for assessing the load resistance of specified glass types, including combinations used in sealed insulating glass units, when exposed to uniform lateral loads of short or long duration, for a specified probability of breakage. This practice applies to vertical and sloped glazing in buildings where the specified design loads consist of wind load, snow load, and self-weight with a total combined magnitude less than or equal to 15 kPa (315 psf). It covers monolithic and laminated glass constructions of rectangular shape with continuous lateral support along one to four edges. The standard does not apply to applications such as balustrades, glass floor panels, aquariums, structural glass members, and glass shelves. It also excludes glass with surface or edge treatments that reduce strength, such as wired, patterned, sandblasted, drilled, notched, or grooved glass. The 2024 revision includes updates to material properties, analytical procedures, and methods for evaluating glass bite pullout, among other editorial changes.
