              This report describes a test method for evaluating the resistance to penetration of high-security windows that are subjected to a combined attack of heat and mechanical impact from firearms, fire axes, hammers, or burning combustibles.
Abstract
              These windows are used in bank teller windows, correctional institutions, and other situations. The discussion lists the equipment to be used, the preparation of specimens, the test setup, and the test procedure. The guidelines emphasize that two people are needed to carryout the test and that teamwork is essential. In addition, those carrying out the test must be familiar with all aspects of the test procedure and must follow suitable safety procedures.
