This thesis aims to implement a bank for impact testing in flat tempered safety glass, based on American Technical Standard ANSI Z97.1, the purpose is to certify the tenacity minimum requirements to be met by flat tempered glass for buildings sold in different countries. Among the specific objectives geometric parameters have been determined, involving greater efficiency and reliability to the construction of the different parts of the bank for testing, this implementation will consist of a beam structure in "C", welded and anchored in a fixed base concrete, to avoid any kind of vibrations. The manufacture of the impactor shall be pear shaped, leather-wrapped and inside will have lead spheres with diameters in the order of 2.5 mm, with a total weight of 45 kg., which exercise the impact from tempered glass at three different heights depending on the quality, classification and certificat...
