NIJ Standard 0101.06 Ballistic Resistance of Body Armor

NIJ standard 0101.06 Personal body armor covered by this standard is classified into five types (IIA, II, IIIA, III, IV) by the level of ballistic performance. In addition, a special test class is defined to allow armor to be validated against threats that may not be covered by the five standard classes. The classification of an armor panel that provides two or more levels of NIJ ballistic protection at different locations on the ballistic panel shall be that of the minimum ballistic protection provided at any location on the panel.
