Buttlesays...I recall, years ago, reading a standard (ISO or ASME, don't recall), on testing "bullet proof" window materials. The requirements were, and I will probably get the numbers wrong, 12 burly young lads, at least 3 of which were right handed, and at least 3 left handed, and a standard set of tools with which to bash windows. Then you encouraged them to bash for a standard time, and evaluated the damage using standard criteria.
