Crash test of components and systems
Today, crash safety in cars is a matter of course. On many components, for example seats, vehicle glass, safety belts, interior fittings etc, there are different demands in the regulations. To reach this security, an extensive research and development is to be needed. A natural part in the development work is the crash test of components and systems. A crash test gives prompt information of the behaviour of the components or systems, which otherwise can be difficult to realize. At SP we have the possibility to perform this type of crash tests. Different crash pulses can be accomplished according to the client’s desire, socalled vehicular specific crash pulses. Naturally, we also can accomplish standardized crash pulses as ECE-R16, ECE-R17 etc.
We have equipment for testing of:
- Seat belts according to ECE-R16, accredited lab
- Car seats and attachments according to ECE-R17, accredited lab
- Disability equipment for vehicles according to ISO-10542 and ISO-7176-19, accredited lab
- Load carrying systems according to ISO 11154 and DIN 75302
- Medical vehicles and their equipment according to TSVFS 1981:33 and EN 1789:1999
The documentation from the tests can be made via data collection with 32 channels and two digital high-speed video cameras. To film the behaviour for a certain component during the test, both the cameras can be mounted at the crash sled. Using the program TEMA, a detailed film analysis of the movement, velocity and acceleration of the test object can be made.
The crash test is not only limited to vehicles. Example for other applications is testing of load-handling shocks, train and boat details, etc.

Both high-speed video cameras can be attached to the crash sled. The films from the cameras can be studied direct after the test. A detailed film analysis of the test object can be made with the program, TEMA, if required.
