1.1本文件确定了安全玻璃产品对以模拟破坏性风暴事件为特征的自然威胁的抵抗力。 1.2本试验方法通过模拟导弹撞击，然后施加循环静压差，确定用于开窗组件的安全玻璃在代表严重破坏性风暴环境中发生的事件的条件下的性能。 1.3一个导弹推进装置、一个气压系统和一个测试室用于模拟一些条件，这些条件可以代表风暴环境中的风传播碎片和压力。 1.4本试验方法测定的性能与建筑围护结构中的玻璃在风暴期间保持无开口的能力有关。

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.
