2 Introduction Rheinmetall Ballistic Protection GmbH provided two armor samples to for ballistic resistance testing on 29 November Threats and Instrumentation 2. Threats* 7.62 x 39-mm, 23-grain PS Ball projectiles *All projectiles were fired from a universal receiver which was fitted with the appropriate barrel and mounted on a NTS- Chesapeake Testing mount. *The threat projectiles were required to have no greater than 3 total yaw. Projectile yaw was measured to ensure that the test impacts were within this constraint by placing a yaw card at the appropriate gun-to-target range during velocity verification shots. 2.2 Instrumentation Projectile velocity measurements were obtained using Oehler Research model 57 infrared screens with Hewlett-Packard (HP) counter chronographs (universal counters, HP model 533A). A digital caliper was used to measure the post-impact deformations observed in the backing clay for selected shots. A digital still camera was used to document the test. Photographs are presented in Attachment A. 3 Details of Test The objective of this test was to conduct a ballistic resistance test on the armor samples in accordance with NIJ-STD-06 Level III (Modified) and the customer s request. spacing between multiple impacts on a single plate was in accordance with the referenced performance standard. s against the armor samples were performed at obliquity and ambient range temperature (65 ± F). For each shot, the target was strapped to a 5.5-in clay/plywood backing that was clamped to a rigid test fixture. All firings were conducted at ft from the target. The velocities used for the test were in accordance with the customer s request. 4 Summary of Results The results of the ballistic resistance test are shown in Table. The round-by-round data sheets for all ballistic resistance testing performed are provided on the following pages. of 4
