Impact ressitant performance of glasses against wind born debris

本文参考了ISO 16932和ASTM E1996、E1886等有关玻璃窗在风载碎片冲击下性能的规范，并对日本的抗冲击试验规范进行了研究，包括日本代表性的风载碎片--屋面瓦的冲击性能，以制定国内标准。我们研制了一种新型空气炮，它既能发射ISO或ASCE标准的导弹，又能发射屋顶瓦片作为导弹。根据ISO和ASCE对浮法玻璃、钢化玻璃、夹丝玻璃和夹层玻璃等各种玻璃进行了一系列耐冲击试验。研究了玻璃在标准导弹和屋面瓦上的抗冲击和断裂特性。提出了冲击性能和建议的标准导弹，其中包括木材导弹相当于屋顶瓦片的破坏力。这些结果发表在论文和期刊评论上，或在专题讨论会和报告会上发表。

We referred some specifications for glazing performance under impact from windborne debris such as ISO 16932 and ASTM E1996, E1886 and examined the specifications for impact resistant test in Japan, including the impact performance of roof tiles, representative windborne debris in Japan, in order to make domestic standards. We made a new designed air cannon which can propel not only the standard missiles of ISO or ASCE but also a roof tile as missile. A series of impact resistant tests based on ISO and ASCE was conducted on various kinds of glasses such as float , tempered , wired, and laminated glass. Impact resistant and fracture characteristics of the glasses against standard missiles and a roof tile were investigated. The impact performance and proposed standard missiles which include a lumber missile with equivalent to a roof tile in destructive power were proposed. These results were published by papers and commentaries of journal or presented at symposiums and lecture meetings.
