The U.S. General Services Administration (GSA) uses a classification system to rate security window films based on the GSA-TS-1-2003 test method. This system measures a glazing system’s ability to contain glass fragments and maintain structural integrity when subjected to an external explosive charge at a 50-meter standoff distance.
The four GSA levels of protection are defined as follows:
- Level 1 (Minimum Protection): Tested against 2.3 kg of TNT. The glass may break, but the film retains fragments and prevents perforation of the glazing. This is typically used for low-risk interior partitions.
- Level 2 (Moderate Protection): Tested against 4.5 kg of TNT. The glazing remains in the frame; while some glass breakage is allowed, the film must prevent major fragmentation. Common applications include office buildings and reception areas.
- Level 3 (High Protection): Tested against 9.1 kg of TNT. The glass may break, but the film retains all fragments and no significant opening is formed. This level is used for government facilities, schools, and high-value commercial buildings.
- Level 4 (Very High Protection): Tested against 13.6 kg of TNT. The glazing remains in the frame and the film retains all fragments with very limited structural breach. This is intended for embassies, critical infrastructure, and military facilities.
Note that these levels represent blast mitigation performance, not ballistic protection. Security window film is NOT bullet-resistant.
