Ul 752 Standard Pdf New Updated Jun 2026

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.

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

If you are in the process of upgrading your facility, I can help you understand the difference between and opaque armor systems , or discuss how to integrate bullet-resistant doors into your design. Testing and Certification for Bullet-Resistant Materials ul 752 standard pdf new

For reference, the older Level 4 threat (a single .30-06 round) is now classified as , and the older Level 8 threat (five 7.62mm rounds) is now classified as UL-RF 4 . The standard now also includes up to Level 10 for specialized high-power scenarios.

Main entryways, administrative offices, and safe rooms increasingly adopt Level 3 or Level 4 materials to mitigate active threat scenarios. Accessing the Official PDF Document Modern testing methods have become more precise

The UL 752 standard categorizes ballistic resistance into distinct levels based on the type of firearm, ammunition, velocity, and number of impacts the material must withstand during testing. Level 1: Small Caliber Handguns

The UL 752 standard evaluates the protective capabilities of materials against specific firearm threats. The testing process determines whether a material can successfully prevent a bullet from completely penetrating it, while also ensuring that no dangerous structural fragmentation (spall) occurs on the protected side. The standard covers a wide range of products, including: Bullet-resistant glazing (glass) Fiberglass panels and opaque armor Security doors, frames, and windows Deal trays and pass-through windows This ensures that "real world" threats are accurately

is a safety standard developed by Underwriters Laboratories (UL) that tests and certifies architectural components—such as windows, doors, barriers, and panels—for bullet resistance.
