适用范围：This International Standard specifies a shock tube test method and classification requirements for explosionpressure-resistant glazing, including glazing fabricated from glass, plastic, glass-clad plastics, laminated glass,glass/plastic glazing materials, and film-backed glass. This International Standard provides a structuredprocedure to determine the blast resistance and the hazard rating of glazing and glazing systems. ThisInternational Standard sets out procedures to classify such security glazing sheet materials by means of testson specimens of a standard size in a standard frame for the purpose of comparing their relative explosionresistance and hazard rating.The procedures and test method can also be used to test, but not classify, glazing systems where the sheetinfill is incorporated into frames purposely designed as complete products of appropriate size for installationinto buildings. This International Standard applies a method of test and classifications against blast wavesgenerated in a shock tube facility to simulate high-explosive detonations of approximately 30 kg to 2 500 kg oftrinitrotoluene (TNT) at distances from about 35 m to 50 m. The classifications approximately represent thereflected pressures and impulses that are experienced by these equivalent threat levels on the face of a largebuilding 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 peakreflected pressure, impulse, positive phase duration and wave-form parameter (decay coefficient), and ratingcriteria, expressed in terms of degrees of glazing damage and fragment impact hazard. Classifications andratings are assigned based upon the performance of the glazing and are specific to the blast characteristicsunder which the test has taken place. Glazing that has received an air-blast classification and rating is suitablefor use in blast-resistant applications only for blasts of comparable characteristics and only if installed in aproperly designed frame. Design based on knowledge of the air-blast resistance reduces the risk of personalinjury.
