Texas Tech's Debris Impact Facility Gains Internationally Recognized Accreditation

The Debris Impact Facility (DIF) at Texas Tech University has received its ISO/IEC 17025 internationally recognized accreditation from the American Association for Laboratory Accreditation (A2LA).  

A2LA

The accreditation comes after a thorough assessment of the quality management system, traceability of measurements and calibrations to national standards, and competence of the National Wind Institute's Debris Impact Facility.

About the Debris Impact Facility

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".
