Summary
"This is an interim report on a project that evaluated the resistance of windows to forced entry by an unskilled attacker using a sledge hammer. To ensure the safety of the attacker and to keep the cost of instrumentation to a minimum, high strength aluminum plates of the same modulus and density as glass were used instead of glass. Aluminum responds like glass under impact, but does not break. The information collected will be used to design a “standard” test procedure and to build special test equipment for evaluating “window” systems proposed to replace single- or double-glazed windows where enhanced security is required."
