Laminated glass fabricated with astm f 2248 tempered glass plies has a tendency to leave the supporting glazing system frame after fracture whereas laminated glass fabricated with annealed or heat strengthened glass plies will remain in the frame and absorb remaining load through tensile membrane behavior.
The width of glazing tape shall be at least equal to two times but not more than four times the thickness designation of the glass to which it adheres. Glass plies used to construct laminated glass are recommended to be either astm f 2248 or heat strengthened glass.
Historical Version s – view previous versions of standard. Values given in parentheses are for information only. This page astm f 2248 last edited on 28 Marchat ASTM F is a standard practice for specifying an equivalent 3-Second Duration design loading for blast resistant glazing fabricated with laminated glass.
Blast testing has shown that astm f 2248 of fully tempered glass plies, when fractured during a blast event, have poorer post blast performance than astm f 2248 or heat strengthened glass plies. Link to Active This link will always route to the current Active version of the standard.

The main keywords to present this standard are air blast pressure, blast resistant glazing, explosion, insulating glass, and laminated glass.
The system shall be designed to astm f 2248 that the glazing fails prior to the framing system that supports the glazing and its attachment to the structural framing system. ASTM International which was funded inis an international standards developing organization that astm f 2248 and publishes standards for a wide range of wstm, products, systems, and services.
astm f 2248 The fasteners that attach the framing system that supports the glazing to the structural framing system shall be designed to resist a uniform load acting on the blast resistant glazing that has a magnitude of at least: This standard was published astm f 2248 ASTM F14 which is a committee specializes about on systems products and services.
Retrieved from ” https: Use of the annealed or heat strengthened glass plies will also reduce the amount of load transferred into the structure.
The astm f 2248 of silicone or glazing tape is referred to as bite and is shown and discussed in Guide C Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. As a minimum, insulating glass shall use laminated glass for the inboard protected side astm f 2248. Views Read Edit View history.
