The bullet, or any fragment of the bullet, must not pass completely through the test sample.

While UL 752 focuses purely on ballistic resistance (stopping bullets), ASTM F3561-22 addresses a different but equally critical vulnerability. This standard tests how well a barrier, like a window or door, can resist a forced entry after it has been shot. In real-world active shooter events, attackers have been known to fire shots to weaken a barrier and then physically smash their way through. ASTM F3561-22 is designed to evaluate a product's ability to prevent that breach. For comprehensive security, professionals should be aware of both standards.

UL 752 is a standard for bullet-resistant materials, specifically designed to evaluate their ability to withstand penetration by bullets and other projectiles. The standard covers a range of materials, including glass, laminated glass, polycarbonate, and acrylic. The testing protocol assesses the material's performance against various types of ballistic threats, including handgun, rifle, and shotgun rounds. ul 752 standard pdf new

Modern polycarbonate, ceramic, and composite matrices perform differently than older materials. Updated standards account for these manufacturing changes.

The standard's core definition of "bullet-resisting" is critical: a barrier must prevent complete penetration by a projectile, stop any fragments of the bullet, and eliminate spalling (shattering of material on the protected side) to a degree that would not cause injury to a person standing directly behind it. It is important to note that UL 752 explicitly does cover personal protective equipment (PPE) such as body armor, helmets, or shields. In real-world active shooter events, attackers have been

Protection against high-velocity rifle rounds.

Rifle threats are categorized by a single, high-velocity shot, with the exception of the 5.56mm and 7.62mm levels, which involve five-shot groups.

This structure eliminates the dangerous assumption that a rifle-rated material naturally stops specialized handgun or shotgun rounds, forcing precise, threat-modeled material specifications. Legacy vs. New UL 752 Performance Cross-Reference
