标准摘要
[中文适用范围]: 本国际标准规定了防爆耐压玻璃的激波管试验方法和分类要求,包括玻璃、塑料、玻璃包塑料、夹层玻璃、玻璃/塑料玻璃材料和覆膜玻璃制成的玻璃。 本国际标准提供了确定玻璃和玻璃系统的防爆性和危险等级的结构化程序。 本国际标准规定了通过对标准框架中标准尺寸的样本进行测试来对此类安全玻璃板材进行分类的程序,以比较其相对防爆性和危险等级。 该程序和测试方法还可用于测试玻璃系统,但不能对其进行分类,其中片材填充物被合并到专门设计为适当尺寸的完整产品以安装到建筑物中的框架中。 本国际标准采用了一种针对激波管设施中产生的爆炸波的测试和分类方法,以模拟约 30 kg 至 2 500 kg 三硝基甲苯 (TNT) 在约 35 m 至 50 m 距离处的高爆爆炸。 这些分类大致代表了垂直于冲击波路径的大型建筑立面表面上这些等效威胁级别所经历的反射压力和脉冲。 分类是根据爆炸冲击波特性(以峰值反射压力、脉冲、正相持续时间和波形参数(衰减系数)表示)和评级标准(以玻璃损坏和碎片程度表示)来定义的冲击危险。 分类和评级是根据玻璃的性能指定的,并且特定于进行测试时的爆炸特性。 已获得空气爆炸分类和评级的玻璃仅适用于具有可比特性的爆炸的防爆应用,并且仅当安装在正确设计的框架中时才适用。 基于抗空气阻力知识的设计可降低人身伤害的风险。 [外文原描述]: ISO 16934:2007 specifies a shock tube test method and classification requirements for explosion-pressure-resistant glazing, including glazing fabricated from glass, plastic, glass-clad plastics, laminated glass, glass/plastic glazing materials, and film-backed glass. ISO 16934:2007 provides a structured procedure to determine the blast resistance and the hazard rating of glazing and glazing systems. ISO 16934:2007 sets out procedures to classify such security glazing sheet materials by means of tests on specimens of a standard size in a standard frame for the purpose of comparing their relative explosion resistance and hazard rating. The procedures and test method can also be used to test, but not classify, glazing systems where the sheet in-fill is incorporated into frames purposely designed as complete products of appropriate size for installation into buildings. ISO 16934:2007 applies a method of test and classifications against blast waves generated in a shock tube facility to simulate high-explosive detonations of approximately 30 kg to 2 500 kg TNT at distances from about 35 m to 50 m. The classifications approximately represent the reflected pressures and impulses that are experienced by these equivalent threat levels on the face of a large building facade positioned perpendicular to the path of the blast waves. Classification is defined in terms of both blast shock-wave characteristics, expressed in terms of peak reflected pressure, impulse, positive phase duration and wave-form parameter (decay coefficient), and rating criteria, expressed in terms of degrees of glazing damage and fragment impact hazard. Classifications and ratings are assigned based upon the performance of the glazing and are specific to the blast characteristics under which the test has taken 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.
