This standard was published by ASTM F14 which is a committee specializes about on systems products and services.
Retrieved from ” https: The standard explain different methods to check the thickness and type of blast resistant glazing fabricated with laminated glass to glaze a fenestration.
Glass plies used to construct laminated glass are recommended to be astm f 2248 annealed or heat strengthened glass.
ASTM International which was funded inis an international standards developing astm f 2248 that develops and publishes standards for a wide range of materials, products, systems, and services. Values astm f 2248 in parentheses are for information only. The system shall be designed to ensure that atsm glazing fails prior to the framing system that supports the glazing and its attachment to the structural framing system.
Blast testing has shown that use of fully tempered glass plies, when fractured during a blast event, have poorer post blast performance than annealled or heat strengthened glass plies.

The width of glazing tape shall be at least equal to two times but not more than four times the thickness designation atsm the glass to which it adheres.
The width of silicone or glazing tape is referred to as bite and is shown and discussed in Guide C Historical Version s – view previous versions of standard. Work Item s – proposed revisions of this standard.
ASTM F 2248
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Laminated glass fabricated with fully 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 astm f 2248 will remain in the frame and absorb remaining load through tensile membrane behavior.
The fasteners that attach the framing system that supports the glazing to the astm f 2248 framing system shall be designed to resist a uniform load acting on the blast resistant glazing that has a magnitude of at least: ASTM F is a standard practice for specifying an equivalent 3-Second Duration design loading for blast resistant glazing fabricated with laminated glass.
As a minimum, insulating glass shall use laminated glass for the inboard protected side lite.

Use of the annealed or heat strengthened glass plies will also reduce the amount of load transferred into the structure.
