The UL 752 Standard for Safety for Bullet-Resisting Equipment was most recently updated with its 12th Edition, published on October 17, 2023. This standard covers materials, devices, and fixtures used to form bullet-resisting barriers for protection against armed attacks. Key Updates in the 12th Edition (2023)
The official 12th Edition is a copyrighted document and is not typically available for free download as a full PDF. Testing and Certification for Bullet-Resistant Materials
Furthermore, the transition to digital accessibility for these standards, such as the search for updated PDF versions, highlights a shift toward more transparent and rapid dissemination of safety information. For architects and security consultants, having the most current version of UL 752 is not merely a regulatory hurdle but a moral and professional imperative. Using outdated specifications could result in the installation of equipment that is insufficient against contemporary ballistic threats. ul 752 standard pdf new
Increased Test Rigor: The new edition requires testing more samples and more shots per sample. For example, the handgun specification (HG-A) now requires 18 shots across three samples, compared to just 6 shots in the previous Level 1.
Modern testing methods have become more precise. Recent editions of the standard may place stricter requirements on the velocity of the bullet during testing. If a bullet travels faster than the specified limit, the product fails; if it travels too slow, the test is invalid. This ensures that "real world" threats are accurately simulated. The UL 752 Standard for Safety for Bullet-Resisting
The UL 752 standard is famous for its "Level" system. Unlike the NIJ (National Institute of Justice) standards which rate vests, UL 752 rates fixed equipment.
The UL 752 Standard for Bullet-Resisting Equipment is the North American benchmark for testing and certifying the ballistic performance of building materials, such as windows, doors, and wall panels. Visit the UL Standards Sales Website: Go to shop
If you are designing a facility for a government RFP, always check the RFP's version requirement. Many now explicitly state: "All ballistic materials shall meet the most current active UL 752 standard as of the date of bid opening."
