ISO 16933:2006提供了一个确定嵌装玻璃抗气流冲击性的结构化程序,并规定了进行安全嵌装玻璃竞技场气流冲击试验所需的仪器、程序、样本、其他要求和指南。七个模拟汽车炸弹的标准爆炸和七个模拟可用于玻璃性能分类的小型背包炸弹的标准爆炸纳入本国际标准,涵盖了广泛的爆炸参数。
安全玻璃,包括由玻璃、塑料玻璃板材料、玻璃包层塑料、夹层玻璃、中空玻璃、玻璃/塑料玻璃材料和薄膜背衬玻璃制成的安全玻璃,可以在标准框架内进行测试和分类,也可以在装有嵌装玻璃的框架内进行测试但不进行分类。
分类和额定值是根据空气冲击压力和脉冲加载的嵌装玻璃的性能来分配的,并且特定于进行试验的爆炸特性。已接受空气喷砂分类和评级的嵌装玻璃仅适用于具有类似特征的喷砂,且仅适用于安装在正确设计的框架中的防爆应用。基于空气冲击阻力知识的设计降低了人身伤害的风险。
ISO 16933:2006 provides a structured procedure to determine the air-blast resistance of glazing and sets forth the required apparatus, procedures, specimens, other requirements and guidelines for conducting arena air-blast tests of security glazing. Seven standard blasts simulating vehicle bombs and seven standard blasts simulating smaller satchel bombs that can be used to classify glazing performance are incorporated in this International Standard and cover a broad range of blast parameters.
Security glazing, including that fabricated from glass, plastic glazing sheet material, glass-clad plastics, laminated glass, insulated glass, glass/plastic glazing materials and film-backed glass, can be tested and classified in a standard frame or tested but not classified in frames provided with the glazing.
Classification and ratings are assigned based on the performance of glazing loaded by air-blast pressures and impulses and are specific to the blast characteristics under which the test takes place. Glazing that has received an air-blast classification and rating is suitable for use in blast-resistant applications only for blasts of comparable characteristics and only if installed in a properly designed frame. Design based on knowledge of the air-blast resistance reduces the risk of personal injury.
