                            1.1  This document determines resistance of security glazing products to natural threats characterized by simulated destructive-windstorm events.1.2  The test method determines the performance of security-glazing for use in fenestration assemblies under conditions representative of events that occur in severe, destructive-windstorm environments using simulated missile impact(s) followed by the application of cyclic static-pressure differentials.1.3  A missile-propulsion device, an air pressure system and a test chamber are used to model some conditions that can be representative of windborne debris and pressures in a windstorm environment.1.4  The performance determined by this test method relates to the ability of glazing in the building envelope to remain without openings during a windstorm.
