While UL 752 focuses purely on ballistic resistance (stopping bullets), ASTM F3561-22 addresses a different but equally critical vulnerability. This standard tests how well a barrier, like a window or door, can resist a forced entry after it has been shot. In real-world active shooter events, attackers have been known to fire shots to weaken a barrier and then physically smash their way through. ASTM F3561-22 is designed to evaluate a product's ability to prevent that breach. For comprehensive security, professionals should be aware of both standards.
