Current Status: Widely recognized as the North American benchmark for ballistic resistance. Relevance: Essential for manufacturers of ballistic glass, doors, transaction windows, and enclosures (guard houses), as well as architects and security consultants.
Older versions allowed a certain amount of glass or laminate fragments to fly off the back side of the barrier. The new standard has tightened these limits significantly. If a bullet stops but sends a spray of glass into the protected area, it is now considered a failure for many applications.
Older versions of standards sometimes focused heavily on single-shot resistance. Newer interpretations and revisions often emphasize multi-shot capabilities—ensuring that a barrier can withstand multiple impacts in a tight grouping without compromising structural integrity.

The newest version of the UL 752 Standard for Bullet-Resisting Equipment 12th Edition , published on October 17, 2023
. This edition introduced a fundamental shift from a hierarchical numeric system (Levels 1–10) to a threat-based designation system organized by firearm type. ANSI Webstore Key Updates in the 12th Edition (New) New Performance Designations
: Replaces the traditional "Level 1-10" with specific firearm categories for better clarity: : Handguns. : Shotguns. Non-Hierarchical Approach Current Status: Widely recognized as the North American
: Unlike the 11th edition, where it was often assumed a higher level protected against all lower threats, the new designations are independent. A material must be tested and certified for each specific threat it claims to resist. Stricter Testing Protocols
: Mandates an increased number of samples, more shots per sample, and more precise shot groupings to reflect realistic attack scenarios. Explicit Scope Clarification
: Formally states that UL 752 does not apply to personal protective equipment (PPE) like body armor or helmets, which remain under NIJ standards. ANSI Webstore Legacy Levels (Still Widely Referenced) Older versions allowed a certain amount of glass
While the 12th edition is the current official standard, many manufacturers still reference the 11th edition legacy levels (1–10) during the industry transition. UL 752, NIJ & ASTM: Bullet-Resistant Glass Standards 2026
It can be tempting to search for a free PDF download of the standard. However, relying on an unofficial, bootleg copy of UL 752 poses significant risks:
If you are searching for a new UL 752 PDF, you are likely looking for the most recent revisions. While the core ratings (Levels 1–10) have remained largely consistent for years, standards bodies like UL constantly evolve their testing protocols.
Here is what is often highlighted in recent revisions and why the "new" version matters:
You cannot assume an installed window is still UL 752 compliant after 10 years. The standard includes requirements for retrofitting and maintenance. Use the PDF to write a quality control plan.
