Laminated glass will be a mass of 1040g steel ball placed from the surface of the sample 1200mm height position, after free fall impact point should be located in the sample geometric center as the center, the radius of 25mm in the circle, observe the composition of the glass has 1 or more pieces of damage. The first thing to look at is the product description provided by the manufacturer, and also to look at the test results of the product. If you can further select the laminated glass selection criteria, you can refer to the following basic principles.
1.In general, the performance of thicker laminated glass will be better than that of thinner.
2.Two laminated glass of the same thickness, the one with more layers is better than the one with fewer layers.
3.The impact resistance of the laminated glass will increase.
4. Laminated glass made of heat-reinforced glass has better impact resistance than ordinary annealed glass and tempered glass.
