One crucial aspect of Level IV plate testing is the measurement of backface deformation (BFD). These conditions help evaluate the armor’s ability to maintain its ballistic performance in different environmental settings, ensuring its effectiveness even under the most challenging circumstances. The plates get exposed to adverse environmental conditioning, including variations in temperature and humidity. To test the ballistic resistance of Level IV plates the selected projectiles are fired at a specific velocity.(2880ft/s ± 30ft/s) This velocity is typically higher than those used for lower-level plates, ensuring that Level IV plates can withstand the impact of high-velocity armor-piercing rifle rounds.ĭuring the testing process, Level IV plates undergo a series of rigorous conditions to simulate real-world scenarios. These rounds are known for their ability to penetrate steel and other materials. ![]() For Level IV plates, the selected projectiles include armor-piercing. The NIJ Standard-0101.06 specifies the types of ballistic projectiles used during the testing process. It covers various aspects of body armor testing, including the selection of test ammunition, velocity requirements, environmental conditioning, and measurement of back face deformation (BFD). This standard provides clear guidelines for manufacturers, testing laboratories, and users to ensure consistency and reliability in ballistic resistance. The NIJ Standard-0101.06 is the primary document that outlines the testing requirements for body armor, including Level IV plates. We will explore some intricacies of Level IV body armor, its composition(s), testing standards, and its significance in safeguarding those who depend on it. However, not all Level IV armors are created equal. Level IV body armor, the highest-rated armor recognized by the NIJ, is designed to offer unparalleled defense against high-velocity rifle rounds, including armor-piercing projectiles like. These levels will range from level II to level IV, with level II being the minimum level of protection that the NIJ will recognize as body armor, only protecting against your standard 9MM. A variety of different levels of protection are set and recognized by the NIJ. The NIJ is an agency responsible for setting standards for ballistic protection in the United States. Regarding body armor, the National Institute of Justice (NIJ) is the ruling body for what armor is rated to protect against. In an era where personal safety is priority number one, body armor can be the difference between life and death, especially when facing life threatening scenarios. ![]() “By failing to prepare, you are preparing to fail” What are Level IV Plates?
