Blast mitigation window film is held to several rigorous industry and government testing standards to ensure performance during explosive events. The primary standards include:
- GSA and ASTM Standards: Films are tested to ensure they can hold glass fragments within a 1-meter perimeter of the window during a blast.
- DHS SAVER Program: The Department of Homeland Security (DHS) System Assessment and Validation for Emergency Responders (SAVER) program provides government validation for these films as a cost-effective security technology.
- WBDG Glazing Hazard Mitigation: According to the Whole Building Design Guide (WBDG), industry standards define glazing hazard mitigation levels from A to D. Professional-grade blast resistant window films typically achieve Level C or higher, which is suitable for commercial buildings facing blast threats.
In real-world performance testing, these films have demonstrated the ability to resist overpressure of 5-10 psi (pounds per square inch) without breaching, including surviving 4.5 psi at a 10-foot standoff. These certifications ensure the film effectively contains fragments, retains glass within the frame post-explosion, and maintains structural integrity for safe evacuation.
