One of the critical requirements in soft ballistic testing is measurement of “back side signature” (i.e. energy delivered to tissue by a non-penetrating projectile) in a deformable backing material placed behind the targeted vest. The majority of military and law enforcement standards have settled on an oil/clay mixture for the backing material, known as Roma …

The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. Tested armor must withstand three hits, spaced 120mm (4.72″) apart, of the designated test threat with no more than 25mm of back-face deformation in order to pass. Of note is the inclusion of special regional …
The Technische Richtlinie (TR) Ballistische Schutzwesten is a regulation guide in Germany for body armor. It is mainly issued for body armor used by the German police, but also for the German armed forces and civilian available body armor. Producers have to meet the criteria of the TR, if they want to participate in open competitive bidding made by German …
In this article we’re going to take a closer look at the process of NIJ Certification, specifically what it means for the end user and why you should buy NIJ certified body armor. The National Institute of Justice (NIJ) has set a standard criteria for meeting each “protection level”. What you might not know is …
Level IIA Tested to stop 9mm and .40 S&W ammunition fired from short barrel handguns. No rifle ammunition protection. Level II Tested to stop 9mm and .357 Magnum ammunition fired from short barrel handguns. No rifle ammunition protection. Level IIIA Tested to stop .357 SIG and .44 Magnum ammunition fired from longer barrel handguns. No …
NIJ Body Armor Threat Levels Summary 0101.06 Standard Read More »
Personal body armor covered by this standard is classified into five types (IIA, II, IIIA, III, IV) by 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 …
NIJ Standard-0101.06 has specific performance standards for bullet resistant vests used by law enforcement. This rates vests on the following scale against penetration and also blunt trauma protection (deformation): In the first half of 2018, NIJ is expected to introduce the new NIJ Standard-0101.07. This new standard will completely replace the NIJ Standard-0101.06. The current system of using Roman …
GOST R 50744-95 is the Russian Federation standard for body armor. Prior to the 2017 revision, the threat levels ran from 1 to 6. Noticeably, it included threats with the suffix A, which denote heightened ratings as opposed to lowered ratings in the NIJ standard. The old (pre-2017) standards are as follows: Armor Level Protection Class …
Measuring the ballistic performance of armor is based on determining the kinetic energy of a bullet at impact (Ek = ½ mv2). Because the energy of a bullet is a key factor in its penetrating capacity, velocity is used as the primary independent variable in ballistic testing. For most users the key measurement is the velocity at which no …
