Standards
Bullet resistant products are rated by Underwriters' Laboratories, the U.S. Department of State, the National Institute of Justice, H.P. White and others. We at ARMI provide barriers for retail establishments, financial institutions, and governmental facilities using ballistic materials which meet the appropriate threat levels as identified by various ballistic standards. In commercial establishments, the majority of installations are done
in U.L. levels 1-3 (or equivalent), while many governmental facilities are done in U.L. levels 5-8 (or equivalent). The U.L. bullet resistant ratings chart and WMFL Physical Attack Rating Charts follow below.
