Level 2: Defines bullet resistant glass designed to withstand fire from larger caliber handguns.It must be able to resist a minimum of three 9mm FMJs traveling at a minimum velocity of 1,175 feet per second (f/s) Level 1: Refers to bullet resistant glass able to withstand fire from small caliber handguns.A brief explanation of each level follows: This organization developed the most widely-accepted set of quality standards for bulletproof glass and is one of few Nationally Recognized Testing Laboratories authorized to perform safety testing by the Occupational Safety and Health Administration (OSHA).Įight different levels of ballistics resistant glass have been established by the UL, each capable of withstanding security threats of different magnitudes. The UL rating system is a series of tests established by the Underwriter’s Laboratory (UL), a not-for-profit organization focussed on enhancing public safety by founding sets of standards for various products. So, how is bullet resistant glass tested and rated? In this blog post, Armortex introduces the UL rating system and outlines some of the rating levels in detail. Guaranteeing the specified level of protection requires a testing methodology that can reconcile each of these dynamic factors. Whether the glass succeeds in safely stopping bullets or not depends on several factors, namely: the material and architecture of the glass the severity of the impacting force and the projectile material and the number of subsequent impacts. ![]() Bullet resistant glass is designed to stop projectiles without shattering, absorbing their energy and retaining the bullet. ![]()
