ASTM F2248 – 12

The system shall be designed to ensure that the f2284 fails prior to the framing system that supports the glazing and its attachment to qstm structural framing system. This standard was published by ASTM F14 which is a committee specializes about on systems products and services. 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:.

ASTM F is a standard practice for specifying an equivalent 3-Second Duration design loading for blast resistant glazing fabricated with laminated glass.

The standard explain different methods astk 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. It is the responsibility of t2248 user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Glass plies used to construct laminated glass are recommended to be either annealed or heat strengthened glass.

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. As a minimum, insulating glass shall use laminated glass for the inboard protected side lite. Values given in parentheses are for information only.

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. From Wikipedia, the free encyclopedia. The width 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.

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 plies will remain in the frame and absorb remaining load through tensile membrane behavior.
