UL 752 testing is notoriously stringent. To achieve certification, materials must pass distinct performance metrics during the physical evaluation:
Disclaimer: Ballistic testing requires specialized facilities. Always consult with certified security engineers for project specifications. To give you the most accurate advice on which, I can:
: Threats are now categorized by firearm type rather than just a number: UL-HG : Handguns (e.g., UL-HG-A through UL-HG-D). UL-RF : Rifles (e.g., UL-RF-A through UL-RF-J). UL-SG : Shotguns (e.g., UL-SG-A and UL-SG-B).
Retail pharmacies, small convenience stores, and gas stations. Level 2: High-Power Small Arms Offers protection against heavier caliber handguns. Ammunition: .357 Magnum Jacketed Soft Point (JSP) Velocity: 1,250 to 1,375 fps
Actionable next steps
The UL 752 standard applies to materials, devices, and assemblies designed to provide protection against intentional shooting. It covers a broad range of products, including ballistic glass, armored panels, doors, transfer drawers, and deal trays.
The new 12th Edition addresses a critical flaw in the previous version: the assumption that a higher protection level automatically stopped all threats from lower levels. Because different calibers and ammunition types (like handguns vs. rifles) affect materials differently, the new system uses :
UL standards are copyrighted documents. Distributing a free PDF of the current standard without a license is a violation of intellectual property law. Furthermore, using an unauthorized copy for a construction project opens you up to liability if the document is outdated or counterfeit.
Unlike some standards that focus solely on the material composition, UL 752 evaluates the entire performance of the product under specific, controlled test conditions. The standard ensures that the certified product offers predictable protection based on its designated level. Key Ballistic Protection Levels
It covers everything from portable bullet-resistant shields and structural panels to full transaction windows. The standard ensures that if a product passes the test, it will provide a predictable, certified level of security.
Transaction windows, counter systems, and secure vestibules generally require Level 2 or Level 3 protection.
This standard applies to a wide range of protective products, including: Bullet-resistant glass and glazing materials Armor plates and architectural wall panels Security doors, window frames, and deal trays Bank teller enclosures and guard booths
Improvements in how environmental conditions (such as temperature and humidity) are managed during testing to ensure consistent material behavior.
The UL 752 standard is developed by Underwriters Laboratories (UL). It establishes rigorous testing protocols to determine the ballistic resistance of various materials and structures.
