Abstract: For the purpose of getting the shock wave overpressure threshold and impulse threshold of the tempered glass with a PVB (polyvinyl butyral) interlayer, some experiments of tempered glass were carried out. Several experiments were finished on the tempered glass with the thickness of 6 mm+1.52 mmPVB+6 mm. In each experiment, the blast shock wave parameter tests were performed and the experimental overpressure-time histories were recorded. By observing and recording the experimental phenomena, the experiment near the critical value of the damage threshold was determined. Therefore, combining the test results of the blast shock wave with the experimental design and experimental conditions, the shock wave overpressure threshold and impulse threshold of 6 mm+1.52 mmPVB+6 mm thickness tempered glass were obtained. Experimental results show that the overpressure threshold of the 6 mm+1.52 mm PVB+ 6 mm thickness tempered glass is between 41 and 55 kPa, and the impulse threshold is between 180 and 299 kP a·ms.
