Enhancing Bulletproof Glass Standards: Insights on the new UL 752 and ASTM F3561-22

In the ever-evolving landscape of security, two updated standards are reshaping how professionals evaluate and implement security barriers. The UL 752 12th Edition Standard for Bullet-Resisting Equipment and the ASTM F3561-22 Standard for Forced-Entry-Resistance After Simulated Active Shooter Attacks are essential developments for anyone involved in the design, specification, or installation of physical security systems.

Understanding UL 752: What’s Changed?

For decades, UL 752 has been the go-to standard for assessing ballistic resistance. The hierarchy in the 11th edition allowed professionals to confidently choose materials based on their level ratings, ranging from Level 1 for low-velocity pistol fire to Level 8 for high-powered rifles. However, with evolving threats and materials, some inconsistencies emerged. For instance, materials rated for Level 3 (stopping a .44 Magnum) sometimes performed similarly to Level 6 (stopping a 9mm Uzi), yet had different ratings.

The revised UL 752 12th Edition brings much-needed clarity. It reorganizes ballistic ratings into three distinct tables—Handguns, Rifles, and Shotguns—based on ammunition type rather than a hierarchical structure. This shift makes it easier to align real-world scenarios with the corresponding security measures. Furthermore, the standard increases rigor in testing methodologies, ensuring more samples are tested with greater precision in shot placements.

ASTM F3561-22: Addressing Active Shooter Threats

While UL 752 focuses on ballistic resistance, ASTM F3561-22 fills a critical gap in the industry by addressing the forced-entry resistance of fenestration systems, such as windows and doors, in active shooter situations. Unlike other standards, ASTM F3561-22 evaluates how well a barrier can withstand an intruder’s attempt to force their way through after firing shots.

This standard does not require materials to be bullet-resistant but focuses on whether attackers can breach a barrier after shooting it. Products tested to ASTM F3561-22 are designed to prevent unauthorized entry even after projectiles penetrate. This addresses a common vulnerability in past events where attackers gained access by smashing weakened windows or doors after firing shots.

The Importance of Adopting These Standards

Although the revised UL 752 and ASTM F3561-22 bring significant improvements, industry-wide adoption may be slow. Some manufacturers and third-party labs may hesitate to transition due to the complexities of recertifying products. However, security professionals must stay informed to ensure that they specify solutions capable of withstanding modern threats.
