技术参数 Technical Parameters
钢球直径:25mm(重量为0.635N)。
Steel Ball Specification: Diameter: 25.00±0.05 mm, Mass: 0.635 N.
检测要求 Test Requirments:
进行第一次试验时钢球下落的高度必须低于使玻璃破裂的高度,以保证在钢球落下时不会导致玻璃破裂。然后进行接下来的一系列试验,每次落下的高度增加25mm,直至玻璃破裂。
The initial test shall be conducted with the steel ball released from a height below the critical fracture threshold of the crystal to prevent breakage. Subsequently, perform sequential tests with the drop height incrementally increased by 25mm per trial until crystal fracture occurs.
