1. The degree of curvature of the flat flat tempered glass shall not exceed 0.5% when the bow is formed, and shall not exceed 0.3% when the waveform is used. Impact resistance Six tempered glass samples were tested. The number of sample failures was less than one, and more than or equal to three were unqualified. When the number of damages is 2, another 6 pieces are taken for testing, and all 6 pieces must not be destroyed as qualified.
2. The state of the debris is tested by taking four tempered glass samples. The number of fragments in each 50 mm × 50 mm area must exceed 40, and a small number of long strips are allowed. The length is not more than 75 mm. Not a knife shape, the long strips extending to the edge of the glass form an angle of not more than 45° with the edge
3, Safety Glazing Shot Bag impact performance Take 4 flat tempered glass samples for testing, must meet the requirements of any of the following (1) or (2). (1) When the glass is broken, the sum of the masses of the large 10 pieces of each sample shall not exceed the mass corresponding to the area of 65 m2 of the sample. (2) When the drop height of the shotgun bag is 1200mm, the sample is not damaged.
4. The bending measurement is based on a flat tempered glass product. The sample is placed vertically, and the ruler is placed horizontally against the surface of the sample for measurement. The arc is expressed as a percentage of the ratio of the height of the arc to the length of the string. In the case of a waveform, the percentage of the height of the valley to the peak is expressed as a percentage of the ratio of the peak to the peak or the valley to the valley.
We also have architectural glass testing equipment such as Building Glass Boiling Test Box, Portable Dew Point Meter.
