Book Synopsis Developing a Suite of Ballistic Test Methods in ASTM E54.04 for Better Harmonization and Reuse in Various Ballistic Resistance Performance Standards by : Mark E. Greene
Download or read book Developing a Suite of Ballistic Test Methods in ASTM E54.04 for Better Harmonization and Reuse in Various Ballistic Resistance Performance Standards written by Mark E. Greene and published by . This book was released on 2018 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Institute of Justice (NIJ) develops performance standards for the unique equipment used by law enforcement and corrections agencies for testing and certification of equipment to ensure it is safe and effective. NIJ published the first performance standard for ballistic-resistant police body armor in 1972 and established body armor conformance testing in the late 1970s. The NIJ Compliance Testing Program ensures that body armor purchased and used by law enforcement in the United States meets minimum performance requirements as demonstrated through standardized ballistic testing to the current NIJ Standard 0101.06, Ballistic Resistance of Body Armor , published in 2008. NIJ is presently working on its seventh revision to its performance standard for ballistic-resistant body armor, NIJ Standard 0101.07, anticipated to be published in 2019. The updated standard will include improved test methods for female body armor and updated protection levels for rifle threats. NIJ and the U.S. Army have been cooperating to harmonize laboratory test procedures and practices in ASTM Subcommittee E54.04 Personal Protective Equipment (PPE). Unlike the current and previous versions of the NIJ standard, which have been comprehensive, standalone documents, revision 0101.07 will incorporate by reference a suite of standardized test methods and practices developed in ASTM E54.04. Incorporation of relevant ASTM standards by reference into NIJ standards and U.S. Army requirements and testing documents, for example, affords the opportunity to harmonize laboratory test procedures and practices for both law enforcement and military ballistic-resistant armor and other ballistic-resistant equipment while providing those end-user communities with ultimate control over product specifications, such as the specific threats against which their equipment must protect.
Book Synopsis A Residual Mass Ballistic Testing Method to Compare Armor Materials Or Components (Residual Mass Ballistic Testing Method) by : Benjamin Langhorst
Download or read book A Residual Mass Ballistic Testing Method to Compare Armor Materials Or Components (Residual Mass Ballistic Testing Method) written by Benjamin Langhorst and published by . This book was released on 2014 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: A statistics based ballistic test method is presented for use when comparing multiple groups of test articles of unknown relative ballistic perforation resistance. The method is intended to be more efficient than many traditional methods for research and development testing. To establish the validity of the method, it is employed in this study to compare test groups of known relative ballistic performance. Multiple groups of test articles were perforated using consistent projectiles and impact conditions. Test groups were made of rolled homogeneous armor (RHA) plates and differed in thickness. After perforation, each residual projectile was captured behind the target and its mass was measured. The residual masses measured for each test group were analyzed to provide ballistic performance rankings with associated confidence levels. When compared to traditional V50 methods, the residual mass (RM) method was found to require fewer test events and be more tolerant of variations in impact conditions.
