Tornadoes can cause serious damage. This means that when you’re buying a storm shelter to protect your family, you want to make sure that it will actually do its job. The Debris Impact Test was created to make sure that storm shelters could withstand the power of a tornado. This Stronghold blog explores what exactly a Debris Impact Test is and why it is so important.

What Is A Debris Impact Test?

When a tornado strikes, the fast moving wind is not the only concerning element of the storm. As the tornado moves it picks up debris that can cause damage to your property as well as your loved ones. So, in order to ensure that storm shelters and doors can withstand the impact of storm debris the National Weather Institute came up with a way to test these products.

Over time they ascertained what best represents the damage that tornado borne debris can do is a 2×4 traveling at 100 mph. This is equivalent to the kind of damage an EF5 tornado can do. So, the idea is to launch a 2×4 at this speed directly at the storm door or the storm shelter. If the product can withstand this test without experiencing a compromise to the integrity of the shelter then it passes the test.

NWI Debris Impact Facility

The original facility for debris impact testing is at Texas Tech University in Lubbock, Texas where the National Wind Institute (NWI) was established. The Debris Impact Test Facility at the NWI was established in 1999 and is internationally acclaimed for its work in testing debris impact. There are a few other accredited facilities that can perform the test. In order to be deemed truly safe in a tornado any storm shelters sold much go through this kind of testing that the NWI developed.
