ASTM E1886 provides procedures for determining the performance of exterior building envelope components in withstanding penetration, damage, or loss of integrity when struck by flying debris under hurricane-like conditions. This specification is accompanied by ASTM E1996, which specifies types of missiles and impact velocities to test protective systems per the International Building Code and Florida Building Code requirements. Testing entails launching a designated missile against the specimen and subsequently applying positive and negative cyclic pressure loading. Window, door, and curtain wall performance is critical to avoiding internal pressurization that would result in roof uplift and structural collapse during storms. The technique can be used in products installed in both commercial and residential high-wind areas to protect occupants and maintain structural integrity during storm conditions. It also facilitates insurance authorizations and provides liability protection for manufacturers and contractors.
ASTM E1886 Test Method
| Missile Impact Test | A 2×4-inch timber missile of specified mass is propelled at 50 ft/s to strike the specimen at critical locations. |
| Cyclic Pressure Loading | The specimen is subjected to 4,500 pressure cycles alternating between positive and negative differentials, simulating hurricane wind loads. |
| Damage Evaluation | Inspection of glazing breakage, frame deformation, and breach potential is conducted to determine pass or fail status based on containment. |
