Work Item s – proposed revisions of this standard. This page was last edited on 28 Marchat 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 of the glass to which it adheres. Glass plies used to construct laminated glass are recommended to be either annealed or heat strengthened glass. The width of silicone or glazing tape is referred to as bite and is shown and discussed in Guide C This standard was published by ASTM F14 which is a committee specializes about on systems products and services.

ASTM F2248 – 12

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. It is the responsibility of the user of this standard to establish f2248 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 plies will remain in the frame and absorb remaining load through tensile membrane behavior.
