We have dedicated facilities that provide automated life cycle testing under real world conditions.

When reliability and product image count for your company, you can count on DTB to design a test that will deliver the results that you expect.


Commercial and residential applications, as well as industrial components, all require their own unique levels of reliability and performance.

Whether its ambient cycling, pressure or water hammer tests, or even temperature affects that you need to evaluate, we have the expertise to assist you with a test design that is appropriate for you.



DTB uses our large facilities and the 24/7 operation of the laboratory to provide DV and PV testing in the shortest amount of time possible.

Using our high powered vibration facilities we are able to vibrate 12 to 24 driver or passenger airbags, at the desired environment. These vibration facilities also handle 4 to 8 full IPs at a time.

Our drive-in environmental chambers are used to test entire lot samples at one time, further reducing testing time. We use our Solar Radiation array of lights to test the materials of these IPs to provide ample confidence of proper deployment in the vehicle, simulating many years of service.
