The Massive Paradigm Shift: From Hierarchical Levels to Weapon Classes
: No fragments of the protective material itself (such as glass shards) can break off the back with enough force to injure someone standing directly behind it. Standard Ballistic Ratings (Reference Chart)
The updated standard addresses previous gaps in testing consistency. The "new" 12th edition requires: ul 752 standard pdf new
: 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.
Architects copy the exact UL 752 language into their Divisions 8 (Openings) or 10 (Specialties). They do not just write "bullet resistant glass." They write: "Provide glazing assembly tested to UL 752 (current edition), Level 3, with spall shield on protected side. Provide certified test report from an approved lab." The Massive Paradigm Shift: From Hierarchical Levels to
The UL 752 standard provides a comprehensive rating system that allows users to match the level of ballistic protection with the specific threat environment. While the new 12th edition has reorganized the ratings, the core ballistic performance requirements are based on a well-established set of test parameters. Below is a detailed look at the UL 752 ballistic levels:
The has officially transitioned to its 12th Edition , completely overhauling how physical security professionals, architects, and manufacturers evaluate ballistic barriers. Published by UL Standards & Engagement , this comprehensive update completely eliminates the traditional, linear Level 1 through Level 10 hierarchy. It replaces it with an explicit, threat-specific framework designed for modern architectural and urban safety planning. For example, the handgun specification (HG-A) now requires
, published in October 2023. This update marks a major shift from the traditional numeric hierarchy (Levels 1–10) to a threat-specific designation system designed to reduce confusion for security professionals and architects. ANSI Webstore Key Changes in the 12th Edition
The new UL 752 (12th Ed.) has completely replaced the numerical hierarchy with a new, three-table system that organizes threats by firearm type: .
Courthouses, military checkpoints, and executive suites. Level 5: Military Rifle
The UL 752 test procedure is designed to simulate real-world conditions in a controlled and repeatable manner.
