This means the back face of the material stops a .44 Magnum (L3), but the front face only stops 9mm (L1). The new standard clarifies how to label these asymmetric products to avoid confusion.
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

Tactical facilities, nuclear power plants, and high-threat environments. Level 8: Multiple-Shot Armor-Piercing Rifle
The importance of UL 752 lies in its rigorous testing methodology. Unlike generic ballistic claims, a UL 752 certification requires a product to undergo a standardized sequence of shots under controlled environmental conditions. The test ensures that not only does the projectile fail to penetrate the protected side, but also that no "spalling"—the dangerous fragmentation of the material itself—occurs. This dual focus on penetration and fragmentation is what makes the standard a trusted foundation for security in high-risk environments such as banks, government buildings, and educational institutions.
A high-level rating designed to withstand five shots from a high-powered 7.62mm rifle ("military ball" rounds). Why Access the Updated UL 752 Standard PDF? The official 12th Edition is a copyrighted document
Newer editions refine environmental testing conditions. Materials are evaluated under varying temperature extremes, humidity, and artificial weathering to ensure bullet resistance does not degrade over years of exposure. 3. Strict "No Spall" Verification
Corporate reception areas, financial institutions, and upscale retail storefronts. Level 3: Super-Power Handguns
Reconfirming that the standard applies strictly to architectural components, not personal protective equipment (PPE). While the 12th edition is the current official
: Materials are often tested under various temperature conditions to ensure consistent performance.
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.
