The release of UL 752 12th Edition coincides with another important standard: , the "Standard Test Method for Forced-Entry-Resistance of Fenestration Systems After Simulated Active Shooter Attack." It is important not to confuse these two documents.
Here is what is often highlighted in recent revisions and why the "new" version matters:
Standards for resisting shotgun slugs and buckshot.
A: Approximately every 5 to 7 years. Always check the "Edition" date on the title page of your PDF. As of 2025, the industry is on the 11th or 12th edition depending on the revision year. ul 752 standard pdf new
Offers protection against multiple hits from high-power military rifles, such as the 7.62mm rifle.
The UL 752 standard is the foundational document for ballistic-resistant equipment in buildings. The new has brought essential updates, replacing the old numerical levels with a more logical, non-hierarchical system of designations— UL-HG (Handgun), UL-RF (Rifle), and UL-SG (Shotgun) —and introducing more rigorous testing protocols.
: Old numeric "Levels" (1–10) are being replaced with categories like Handgun (UL-HG) and Rifle (UL-RF) to provide more clarity on specific weapon threats. The release of UL 752 12th Edition coincides
This category covers both slugs and buckshot, which present different types of mass and fragmentation threats.
New iterations clarify the velocity tolerances required during testing, reducing statistical variances across independent laboratory trials. The updates provide standardized metrics for multi-shot spacing, ensuring that successive impacts accurately simulate real-world attack vectors. Focus on Composite Materials
For decades, the 11th edition of UL 752 was the gold standard for structural ballistic safety in North America. However, to address evolving threats and inconsistencies, UL published a comprehensive revision. The current and most up-to-date version is , officially designated UL 752 Ed. 12-2023 , which was published on October 17, 2023. Always check the "Edition" date on the title
