In response to requests of the Office, Chief of Ordnance, and in cooperation with various steel producers, tests have been conducted over a period of several methods, on various steels in varying conditions of treatment. While the results of these tests have been reported, as they have been completed in Watertown Arsenal reports, an attempt is made in this report to collate and integrate the results of the several tests. In attempting to evaluate the means of a single ballistic limit test, the relative resistance of various materials with respect to service attack, there were developed several fragment-simulating projectiles. These projectiles, in addition to cal. .45 ball projectiles which have been used traditionally to evaluate ballistically helmet materials, have been used to test materials submitted for ballistic evaluation. The results of tests conducted on the various steels are recited in Tables I to XIX.
