Since 1976, NTA has been offering product testing, inspection, and certification to the building products industry. Accredited to ISO 17025 as a testing laboratory, ISO 17020 as an inspection agency, and ISO 17065 as a certification body, ICC NTA has long been the go-to third-party provider for companies in the building products arena who need assistance with product testing and/or code evaluation. As part of its building envelope testing services, ICC NTA works with manufacturers of fenestration products (windows, doors), vinyl siding, water-resistive barriers (WRBs), wall systems, and more.

NTA Fenestration Test wallIn Summer 2018, ICC NTA added a new and improved Test Wall and Impact Cannon to its Midwest Testing Laboratory located in Nappanee, Indiana. The new Test Wall provides air, water, and structural testing on a wide variety of products, and the cannon provides impact testing to simulate windborne debris experienced during a hurricane or tornado event. The Test Wall can be used to establish a product’s compliance with standards such as those published by AAMA and ASTM. At 16’ high by 18’ wide, the ICC NTA Test Wall can test one large specimen or multiple smaller specimens at the same time. “For many years, ICC NTA has offered accredited services for air/water/structural and impact testing,” says Justin Mann, Operations Manager for NTA’s Midwest Testing Laboratory. “Now with our upgraded equipment, we will be more efficient and offer faster turnaround times for our clients, further reducing their time to market and positively impacting their bottom line.” To see a short video of a rain demo, click here.


The New Impact Cannon Simulates Windborne Debris

NTA Impact CannonAn important part of the Test Wall system is the Impact Cannon, which simulates wind-borne debris experienced during a hurricane or tornado event. Testing and performance requirements for demonstrating tornado and hurricane resistance are addressed by standards such as ASTM E1886, ASTM E1996, Florida’s TAS 201, FEMA 361, and ICC 500. Our powerful new Impact Cannon has the ability to shoot a 9-lb, 8-ft long 2×4 at 128 mph for hurricane testing and a 15-lb, 14-ft long 2×4 at 100 mph for tornado testing.

ICC NTA Sets a New Standard for Eco-Conscious Testing
The testing required to demonstrate a product’s water penetration resistance uses a lot of water, especially the two-hour wind-driven rain test prescribed by Chapter 14 of the International Building Code (IBC) for wall systems that don’t utilize a traditional water-resistive barrier (WRB). Most test labs consume thousands of gallons of water per year. ICC NTA wanted to do things differently, so we utilize a 300-gallon water tank to recycle the water used for testing. We are very proud to say that our environmental impact of water waste will be greatly reduced because of our water recycling system.
