STANAG 2920

STANAG 2920
Name	STANAG 2920
Number	2920
Title	Ballistic test method for personal armour materials and combat clothing
Status	NATO standardization agreement
Year adopted	1985
Domain	personal armour testing

STANAG 2920 is a NATO standardization agreement that defines a ballistic test method for evaluating personal armour materials and combat clothing used by armed forces and security services. The standard provides procedures adopted by members including North Atlantic Treaty Organization, United States Department of Defense, Ministry of Defence (United Kingdom), Bundeswehr, and other national defence organizations to assess resistance against small-arms fragments and projectiles. It underpins interoperability between suppliers such as BAE Systems, Rheinmetall, General Dynamics, and research institutions like Royal Military College of Canada, Defence Research and Development Canada, and Fraunhofer Society.

Overview

STANAG 2920 specifies criteria for measuring the ballistic performance of materials used in helmets, vests, shields, and clothing developed by manufacturers such as Honeywell International Inc., DuPont de Nemours, Inc., and Teijin Ltd.. The agreement addresses test conditions referenced by laboratories including Sandia National Laboratories, Lawrence Livermore National Laboratory, and Cranfield University to ensure comparability with allied standards like those from National Institute of Justice, National Physical Laboratory (UK), and European Committee for Standardization. Adoption has influenced procurement by forces such as the United States Army, British Army, French Army, Italian Army, and Canadian Armed Forces.

Measurement Methodology

The methodology prescribes firing defined projectiles produced by manufacturers tied to ballistic research such as Norma Precision AB and Federal Cartridge Company at standardized velocities measured with equipment from firms like Ophir Optronics Solutions and institutions such as National Institute of Standards and Technology. Test ranges similar to those at Aberdeen Proving Ground, Pillau Range, and Yuma Proving Ground employ chronographs, high-speed cameras developed by Photron Limited, and witness materials analogous to those used by Ballistics Research Laboratory. The procedures define mounting frames, sample conditioning derived from protocols used by International Organization for Standardization, and environmental controls inspired by laboratories at Argonne National Laboratory and École Polytechnique Fédérale de Lausanne.

Armor and Projectile Classification

STANAG 2920 distinguishes material performance based on impact from standardized fragments and projectiles produced according to manufacturers and foundries like Avibank, FN Herstal, and Sellier & Bellot. The classification scheme correlates test results with threat assessments used by units such as United States Marine Corps, NATO Response Force, and French GIGN. It intersects with other standards for ballistic threats developed by organizations including OTAN, Northrop Grumman, and Lockheed Martin, and is referenced in comparative studies at universities like Massachusetts Institute of Technology, University of Oxford, and Technische Universität München.

Applications and Use in NATO

Member states apply STANAG 2920 in procurement programs overseen by entities such as Alliance Ground Surveillance, NATO Support and Procurement Agency, and national procurement arms like Defense Logistics Agency. The standard informs fielding of personal protective equipment by formations including International Security Assistance Force, ISAF, European Union Battlegroups, and peacekeeping contingents linked to United Nations mandates. Contractors bidding for contracts with Ministry of Defence (India), Defence Materiel Organisation (Netherlands), and other procurement agencies often supply compliance documentation referencing test houses like QinetiQ and TÜV SÜD.

Test Equipment and Procedures

Approved test equipment includes gas-gun systems and ballistic ranges manufactured by companies such as Yorkshire Ballistics, instrumentation by Kistler Group, and witness panels produced by suppliers comparable to ArmoRoc. Procedures require calibration traceable to standards from National Physical Laboratory (UK), Physikalisch-Technische Bundesanstalt, and National Metrology Institute of Japan, with quality systems aligned to ISO 9001 and test accreditation bodies like International Laboratory Accreditation Cooperation and United Kingdom Accreditation Service. Data acquisition and reporting formats mirror practices at research centers such as Aachen University, Imperial College London, and Royal Military Academy (Belgium).

Limitations and Criticisms

Critics from academic groups at University of California, Berkeley, Delft University of Technology, and Université de Montréal note that STANAG 2920 focuses on discrete impacts and may not represent complex battlefield effects encountered in theaters like Afghanistan, Iraq War, and Yugoslav Wars. Analysts from think tanks including RAND Corporation, International Institute for Strategic Studies, and Center for Strategic and International Studies argue for integration with multi-hit, blunt trauma, and fragmentation models developed at Johns Hopkins University and University College London. Manufacturers and procurement agencies such as BAE Systems, General Dynamics, and NATO Support and Procurement Agency debate updates to accommodate novel materials from firms like 3M Company and research consortia at European Defence Agency.
