NIJ's Body Armor Web pages discuss the Body Armor Safety Initiative; explains the results of body armor research and explores future research; provides information on standards and testing; and offers links to resources that help agencies select and fund body armor purchases." (August 30, 2007).
Body Armor: The Department of Justice (DOJ), as part of its ongoing Body Armor Safety Initiative testing, announced on August 24, 2005 that test results indicate that used Zylon-containing body armor vests may not provide the intended level of ballistic resistance.
As a result, body armor models that contain Zylon will not be compliant, unless their manufacturers provide satisfactory evidence to NIJ that the models will maintain their ballistic performance over their declared warranty period.Another article summarizes findings from an NIJ-sponsored conference about suicide terrorism.The conference brought together experts in the field to discuss findings and share views on suicide terrorism, what compels individuals to join terrorist organizations, and the utility of a central database of research on the topic. Griffiths, David Jurgens, Dan Jurafsky, and Jennifer L. of Homeland Security, Science and Technology Directorate, prepared by the Space and Naval Warfare Systems Center (April 2015).In the tests, age and appearance of used Zylon-based vests were ineffective predictors of potential ballistic performance.NIJ's research also showed that ballistic-resistant material, including Zylon, can degrade as a result of exposure to environmental conditions, such as moisture and light.
