The purpose of this standard is to establish minimum performance requirements and test methods for the ballistic resistance of personal body armor intended to protect the torso against gunfire. This standard is a general revision of NIJ Standard−0101.03, dated April 1987, updating the labeling requirements, acceptance criteria, test ammunition, procedures, and other items throughout the standard. Revision A of NIJ Standard−0101.04, dated June 2001, provides clarification to the text, methodology and test procedures of NIJ Standard−0101.04. The scope of the standard is limited to ballistic resistance only; this standard does not address threats from knives and sharply pointed instruments, which are different types of threat.
