UL 752 Ballistic Glass
UL 752 is a widely recognized standard for ballistic-resistant materials, including glass. This standard, developed by Underwriters Laboratories (UL), classifies ballistic-resistant materials into various levels based on their ability to withstand different types of ballistic threats, such as bullets and projectiles. Each level represents a different degree of protection. UL 752 is often used to assess the ballistic performance of glass and other building materials.
Here are some key details about UL 752 ballistic glass levels:
-
Level 1: This level is designed to resist handgun threats, typically 9mm and .38 Special ammunition.
-
Level 2: Provides protection against higher caliber handguns, such as .357 Magnum and 9mm submachine guns.
-
Level 3: Offers protection against more powerful handguns, like .44 Magnum and 12-gauge shotgun rounds.
-
Level 4: Designed to withstand high-velocity rifles, such as .30-06 and 7.62mm ammunition.
-
Level 5: Provides protection against military-grade rifles, including 7.62mm and .223 Remington ammunition.
-
Level 6: Offers the highest level of protection against very high-velocity military rifles and armor-piercing ammunition.
The specific thickness and construction of ballistic glass required to meet each UL 752 level can vary, and it is essential to consult with manufacturers or security professionals to ensure that the chosen glass provides the necessary protection for a particular application.
Ballistic glass is commonly used in applications where security and protection against firearms are essential, such as banks, government buildings, military facilities, armored vehicles, and critical infrastructure.
