Yes, ASTM F3561 is considered the modern benchmark and framework for evaluating forced entry resistance, particularly in school security, commercial, and high-security applications. Unlike earlier standards (such as ASTM F588) that relied on static loads or simple impact counts, ASTM F3561 introduces a time-based methodology that replicates real-world threats.
Key reasons why this standard is used for modern security include:
- Time-Based Metrics: It quantifies resistance in seconds, allowing facility managers to align security hardening with operational response plans (e.g., lockdown procedures).
- Realistic Attack Simulation: The protocol uses a structured progression of tools, including screwdrivers, pry bars, hammers, and sledgehammers, to simulate a determined intruder.
- Dynamic Testing: It measures how long a complete glazing assembly—including the glass, frame, and impact protection attachment systems—can withstand a sustained physical assault.
- Standardized Levels: It provides clear performance grades (typically Level 1 through Level 4), ranging from a 60-second delay to over 300 seconds of resistance.
While ASTM F3561 is the modern standard for forced entry, it is important to note that it does not measure bullet resistance. Security film tested to this standard is intended to delay entry and contain glass fragments, not to stop ballistic threats.
