PURPOSE AND SCOPE
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.

PURPOSE AND SCOPE
Ballistic Resistance of Body Armor NIJ Standard-0101.06 establishes minimum performance requirements and test methods for the ballistic resistance of personal body armor designed to protect the torso against gunfire. The standard is limited to ballistic resistance only and does not address resistance from knives or other sharply pointed objects. It reviews NIJ body armor classifications, details requirements (e.g., acceptance criteria, workmanship and armor backing material), and discusses test methods (e.g., velocity measurement equipment, wet conditioning and test preparation.).

This standard supersedes NIJ 2005 Interim Requirements, Ballistic Resistance of Body Armor (August 2005) and also supersedes NIJ Standard-0101.04 Rev. A, Ballistic Resistance of Personal Body Armor (June 2001).

PURPOSE AND SCOPE
The purpose of this standard is to establish minimum performance requirements and methods of test for ballistic resistant protective materials. This standard supersedes NIJ Standard-0108.00, Ballistic Resistant Protective Materials, dated December 1981. This revision adds threat level III-A and establishes threat level classifications that are consistent with other NIJ standards for ballistic protection.

This standard is applicable to all ballistic resistant materials (armor) intended to provide protection against gunfire, with the exception of police body armor and ballistic helmets, which are the topic of individual NIJ performance standards [1,2]1. Many different types of armor are now available that range in ballistic resistance from those designed to protect against small-caliber handguns to those designed to protect against high-powered rifles. Ballistic resistant materials are used to fabricate portable ballistic shields, such as a ballistic clipboard for use by a police officer; to provide ballistic protection for fixed structures such as critical control rooms or guard stations; and to provide ballistic protection for the occupants of vehicles. The ballistic resistant materials used to fabricate armor include metals, ceramics, transparent glazing, fabric, and fabric-reinforced plastics; they are used separately or in combination, depending upon the intended threat protection.

PURPOSE AND SCOPE
The purpose of this standard is to establish minimum performance requirements and methods of test for the stab resistance of personal body armor intended to protect the torso against slash and stab threats. This standard is based on technical work performed by many organizations: in the United Kingdom by the Police Scientific Development Branch, and in the United States by the National Institute of Standards and Technology and its subcontractors.

The scope of the standard is limited to stab resistance only. The standard does not address ballistic threats, as those are covered by NIJ Standard–0101.04, Ballistic Resistance of Personal Body Armor. The standard does not directly address slash threats; however, testing has shown that stab threats are by far the more difficult to defeat, and that body armor capable of defeating stab threats will perform satisfactorily against slash threats.
