Debris Impact Facility
The Debris Impact Facility is an A2LA accredited ISO/IEC 17025-2005 a2latest laboratory. DIF offers accredited storm shelter, safe room, a2lacommercial and residential door, window, and other componentsa2la testing in accordance with FEMA 320, FEMA 361 and ICC-500, a2laincluding structural performance of exterior a2ladoors, windows, curtain walls, and skylights by Uniform Static Air pressure testing, determining the ability of elements of the building envelope to remain unbreached during severe windstorm event, including hurricanes or tornadoes.
The Debris Impact Facility is intended to promote public safety and welfare and helps prevent deaths and lower property losses incurred due to extreme weather events and their effects. DIF performs debris impact tests on storm shelters, shelter components and building materials in order to develop the safest, most impact-resistant materials to better protect individuals.
The heart of the Debris Impact Facility is a pneumatic cannon capable of producing simulated wind speeds over 250 mph. The cannon can launch different types of simulated wind-born debris in a controlled environment to provide valuable impact resistance data.
The cannon plays an important role in researching effective tornado shelters for use in homes and other structures. The cannon is used to develop standards for safe above ground shelters, and continues to be in demand for testing new shelter materials and constructions.
The NWI has also been selected for Popular Science’s “Most Awesome College Labs 2013" and as one of "PopSci's Most Awesome College Labs 2011".
