    Terminal ballistics Terminal ballistics, a sub-field of ballistics, is the study of the behavior and effects of a projectile when it hits its target.[1] Terminal ballistics is relevant both for small caliber pro- jectiles as well as for large caliber projectiles (fired from artillery). The study of extremely high velocity impacts is still very new and is as yet mostly applied to spacecraft design. 1 General An early result is due to Newton; the impact depth of any .32 ACP full metal jacket, .32 S&W Long wadcutter, .380 ACP projectile is the depth that a projectile will reach before jacketed hollow point stopping in a medium; in Newtonian mechanics, a pro- jectile stops when it has transferred its momentum to an equal mass of the medium.

  • Ballistic Resistant Protective Materials
    U.S. Department of Justice National Institute of Justice National Institute Technology Assessment of Justice Program Ballistic Resistant Protective Materials NIJ Standard 0108.01 ABOUT THE TECHNOLOGY ASSESSMENT PROGRAM The Technology Assessment Program is sponsored by the Office of Development, Testing, and Dissemination of the National Institute of Justice (NIJ), U.S. Department of Justice. The program responds to the mandate of the Justice System Improvement Act of 1979, which created NIJ and directed it to encourage research and development to improve the criminal justice system and to disseminate the results to Federal, State, and local agencies. The Technology Assessment Program is an applied research effort that determines the technological needs of justice system agencies, sets minimum performance standards for specific devices, tests commercially available equipment against those standards, and disseminates the standards and the test results to criminal justice agencies nationwide and internationally. The program operates through: The Technology Assessment Program Advisory Council (TAPAC) consisting of nationally recognized criminal justice practitioners from Federal, State, and local agencies, which assesses technological needs and sets priorities for research programs and items to be evaluated and tested. The Law Enforcement Standards Laboratory (LESL) at the National Bureau of Standards, which develops voluntary national performance standards for compliance testing to ensure that individual items of equipment are suitable for use by criminal justice agencies. The standards are based upon laboratory testing and evaluation of representative samples of each item of equipment to determine the key attributes, develop test methods, and establish minimum performance requirements for each essential attribute. In addition to the highly technical standards, LESL also produces user guides that explain in nontechnical terms the capabilities of available equipment.
