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.
