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 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 – Wikipedia

From Wikipedia, the free encyclopedia. Values given in parentheses are for information only. 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: The system shall be designed to ensure that the glazing fails prior to the framing system that supports the glazing and its attachment to the structural framing system.

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. ASTM International which was funded inis an international standards developing organization that develops and publishes standards for a wide range of materials, products, systems, and services.

Work Item s – proposed revisions of this standard. 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. The system shall be designed to ensure that the glazing fails prior to the framing system that supports the glazing and its attachment to the structural framing system.

Values given in parentheses are f22248 information only. Glass plies used to construct laminated glass are recommended to be either annealed or heat strengthened glass. Views Read Edit View history. The width of glazing tape shall be at least asfm to two times but not more than four times the thickness designation of 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 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 ff2248 remain in the frame and absorb remaining load through tensile membrane behavior.

Laminated glass axtm 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.

Use of the annealed or heat strengthened glass plies will also reduce the amount of load transferred into the structure. Glass plies used to construct laminated glass are recommended to be either annealed or heat strengthened glass.

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