ASTM F2247 Performance Response Categories
Beyond PSI rating, blast doors are classified by their post-blast condition. The appropriate category depends on operational requirements and personnel safety considerations.
| Category | Response | Post-Blast Condition | Operability | Recommended For |
|---|---|---|---|---|
| Category I | Elastic Response | No permanent deformation | 100% Operational | Critical egress routes, security checkpoints |
| Category II | Controlled Plastic | Measurable deformation, ≤2.0° edge rotation | Maintained | Petrochemical standard (PIP STC01018), personnel areas |
| Category III | Significant Plastic | Non-catastrophic failure, ≤8° edge rotation | Lost | Unmanned areas, equipment rooms, most DoD applications |
| Category IV | Catastrophic Failure | Door may detach, severe deformation | Failed | Not recommended - fails to provide protection |
Selecting the Right Blast Rating
Determine Threat Level
Work with security consultants or reference UFC 4-010-01 threat assessment guidelines.
Calculate Blast Load
Blast pressure depends on charge weight and standoff distance.
Select Category
Category II for personnel areas, Category III for unmanned spaces.
Consider Impulse
Complete specs include peak pressure, duration, and impulse.
Understanding Pressure vs. Total Load
Door size significantly affects total load even at identical PSI ratings:
Larger doors require proportionally stronger construction to achieve the same PSI rating.
Construction & Materials
Engineering the blast resistant door system from frame to finish
Door Leaf Construction
Standard Steel Blast Door
1-5 PSI Range
Standard construction for government buildings, commercial applications, and moderate protection requirements. Most common configuration for UFC 4-010-01 Low Level of Protection.
Face Skins
14-16 gauge (low range), 12-14 gauge (mid range)
Hot-dip galvanized or phosphate pretreatment
Core
High-density mineral fiber (120-200 kg/m³)
Provides mass for inertial resistance
Heavy-Duty Steel Blast Door
6-20 PSI Range
Armor Plate Blast Door (AR-500)
20-50+ PSI Range
Frame Systems
Welded Steel Frame
New construction, all PSI ratings
- Material: 12-gauge min (10-gauge for 5+ PSI)
- Depth: 4-3/4" to 8"+
- Anchorage: Embedded in concrete or welded to steel
Recommended for new construction
Heavy-Duty Blast Frame
Mid and high-range PSI ratings
- Material: 10-gauge or heavier
- Depth: 6" to 10"
- Anchorage: Engineered anchor system

- Depth: 4-3/4" to 6"
- Anchorage: Expansion anchors
Limited to 1-3 PSI applications
Hardware Systems
| Component | Low-Range (1-3 PSI) | Mid-Range (4-5 PSI) | High-Range (6+ PSI) |
|---|---|---|---|
| Hinges | 3× heavy-duty ball bearing, 4-1/2" × 4-1/2" | 4× blast-rated or continuous hinge | Continuous blast hinge or 5+ pivot hinges |
| Locking System | Multi-point lock (2-point minimum) | 3-point min with reinforced strikes | 5+ point with proprietary blast latches |
| Seals | Compression gaskets (EPDM/neoprene) + optional intumescent for fire rating | ||
Critical: Hinges and locks are common failure points under blast loading. Must be rated for calculated blast load. Lock disengagement under dynamic loading voids protection—specify locks tested as part of complete door assembly.
