Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. Use of the annealed or heat strengthened glass plies will also reduce the amount of load transferred into the structure.

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.
