Exponent's Test and Engineering Center (TEC) can easily conduct full-scale crash tests at a rate of about 25 per month. Some of these tests are conducted in accordance with the established FMVSS procedures, such as 208, 214, or 301, which not only define the vehicle impact mode, but also detail specific requirements concerning instrumentation (transducer selection, orientation, calibration, filtering, etc.), camera coverage, and dummy certification and positioning. Others are conducted to support manufacturers' research and development efforts. All of our tests follow the SAE J211 guidelines, which are required by the federal government for conducting and documenting safety compliance tests.
The majority of the tests conducted at the TEC are one of a kind in terms of vehicle impact mode. We have reproduced accident-scene features such as ditches, poles, trees, walls, guard rails, and ramps. We have crashed motorcycles into trucks, cars into cars, and even semi-tractors into cars or our fixed barrier. We also conduct rollover tests and re-create impacts of two moving vehicles at nearly any relative angle and speed.
Rollover Testing 
Exponent's TEC provides many options for rollover crash testing. Some rollover tests that we have conducted have involved ramps or dollies (including FMVSS 208). Others have simulated the more common, real-world condition of a lateral slide into a dirt- or curb-tripped roll. Rollovers are also simulated on our Roller Coaster Dolly or by using our crashworthy automated steering controller. When clients are interested in reproducing a particular roof strike during a rollover test, we conduct an inverted drop test or use our controlled rollover impact system (CRIS).
The TEC played a key role in the development of new SAE recommended practices for occupant protection in heavy-truck rollovers, by developing new test protocols and fixtures.
Sled Testing
Exponent offers sled testing services to a wide range of clients/developers. Many of these tests are conducted for the purpose of evaluating occupant injury or protection in a crash scenario. The sled is also used to test performance of system components, such as airbag crash sensors or fuel-system components.
In 1991, Exponent’s TEC was the first commercial facility to offer aircraft-seat dynamic certification testing in the United States. Since that time, we have conducted several hundred aircraft-seat sled tests for seat manufacturers interested in developing and/or certifying their designs.
The pre-impact braking/deceleration feature on the indoor sled offers clients an additional service. Exponent has conducted sled tests with pre-impact braking to generate low-level pre-impact decelerations. These tests have been beneficial to clients investigating restraint performance with out-of position occupants. The pre-impact braking feature has also been used to decelerate a complete vehicle, causing a tip-up of the vehicle without final impact.
