Test & Approvals

Tornado Safe Room's Wall Assembly Debris Impact Test at Texas Tech Securall Tornado Safe's FEMA 320/361/ICC-500 Proprietary Wall Assembly passed three impacts and meets both the FEMA 320 and the ICC-500 standards for wall systems in storm shelters . The tornado test criterion uses a 15-lb. 2x4-in. wood board traveling horizontally at 100-mph, which corresponds to a 250-mph wind, and is the criterion used in designing vertical surfaces for occupant protection.

Tornado Safe Door Pressure & Debris Impact Test at Texas Tech Pressure and Impact tests were conducted at Texas Tech University’s Wind Science and Engineering Research Center. The test on FEMA 320/ICC-500, Model HD42x84-O-LH was consistent with the guidelines of FEMA 320/361 and ICC-500 (2008) Standard for “The Design and Construction of Storm Shelters” and the ICC-500 requirement that the pressure test load should include a safety factor of 1.2. This pressure relates to a 250 mph ground speed tornado and the door installed in Zones 4&5 per ASCE 7-05 for a corner zone with the negative pressures being greater than the positive pressures. The goal pressure is 2.19 psi which must be held for 10 seconds in accordance to ASTM E330. In accordance to FEMA 320, the residential shelter guideline, swinging door assemblies should resist a static pressure of 1.37-psi for a 5-second period. The tornado test criterion uses a 3 impacts of 15-lb. 2x4-in. wood board traveling horizontally at 100-mph, which corresponds to a 250-mph wind.

Test Results FEMA 320/ICC-500, Model HD42x84-O-LH door assembly passed 2.19 psi for 10 sec.(includes ICC-500,1.2 Safety Factor) & three impacts and is qualified to meet both the FEMA 320 and the ICC-500 standards of door pressures and impacts for doors in storm shelters.
