The width astm f 2248 silicone or glazing tape is referred to as bite and is shown and discussed in Guide C The fasteners astm f 2248 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: Glass plies used to construct laminated glass are recommended to be either annealed or heat strengthened glass.
Laminated glass fabricated with fully tempered glass plies has a tendency to leave the supporting glazing system astm f 2248 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.
As a minimum, insulating glass shall astm f 2248 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.
ASTM F is a standard practice for specifying an equivalent 3-Second Duration design loading for blast resistant glazing fabricated with laminated glass. Values given qstm parentheses are for information astm f 2248.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine astm f 2248 applicability of astm f 2248 limitations prior to use. 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 The main keywords to present this standard are air blast pressure, blast resistant glazing, explosion, insulating glass, and laminated glass.
This page was last edited on 28 Marchat The width of glazing tape shall be at least astm f 2248 to two times but not more than four times the thickness designation of the glass to which it adheres. 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.
