Endurance tests on vehicle seats are carried out using classic vibration tests, multi-stage/block tests or cyclic ramp tests. Both the metallic seat structures and fully upholstered seats are analysed. The force is applied via back and buttock dummies in order to reproduce a load that is as close to reality as possible.

Multi-axis tests are easy to realise with the help of the DYNA-MESS test axes. The testing software is configured for several axes and then ensures that the overall test is carried out correctly. In multi-axis tests, the correct sequence of loads or – in the case of simultaneous loading by several axes – the temporal synchronisation of the axes is important.

Many test specifications stipulate alternating loads in two directions. Thanks to the servo technology used, these loads can be applied with just one test axis. The axis-integrated force and displacement measurement ensures that the desired loads and positions are approached precisely.

In addition to testing the seat structures, test axles are used for the continuous actuation of seat adjustments (seat length adjustment, seat height adjustment). These continuous function tests can be carried out in combination with electrical adjusters (backrest adjustment, etc.). The DYNA-MESS test software enables simple control of these motors.

To determine the backrest play and seat rigidity, the seats are subjected to a quasi-static load up to a test force. Additional displacement sensors (displacement sensors, laser displacement measuring systems, etc.) are used to measure the deformation of the seat structure at defined positions.

The requirements for sandwich elements (panels) are described in DIN EN 14509: “Self-supporting sandwich panels with metal facings on both sides – Factory made products – Specifications”.

The standard specifies the requirements for prefabricated self-supporting sandwich insulation elements with a metal facing on both sides, which are intended for overlapping installation in the following applications:

The insulation core materials covered by this standard include rigid polyurethane foam, expanded polystyrene, extruded polystyrene foam, phenolic resin foam, cellular glass and mineral wool.
