    ASTM E3003-15 Standard Practice for Body Armor Wearer Measurement and Fitting of Armor

    Over the past few years, ASTM has collaborated with the National Institute of Justice (NIJ) to create standard test methods and practices for body armor. These standards can be used by ballistic laboratories to improve testing, and by law enforcement officers to improve how they select and wear ballistic-resistant vests. Many of these new standard test methods will be incorporated into future revisions of NIJ’s performance standard for law enforcement body armor, Ballistic Resistance of Body Armor.

    A greater emphasis on ensuring that law enforcement officers wear body armor that properly fits and provides adequate coverage led to the development of ASTM E3003 Standard Practice for Body Armor Wearer Measurement and Fitting of Armor. Although ASTM normally charges for access to its standards, in order to help improve officer safety and better protect officers during deadly assaults, ASTM is making the E3003 Standard available for download. The standard includes guidance on how to properly measure wearers, and what officers should consider when putting on and adjusting their protective vests, in order to maximize the vest’s coverage and protection of critical body areas.
