Pressure/suction exposed objects

Ausschnitt der IFI-Stadt, Druck-Sog-Wechsel

A special case of aerodynamic loads are pressure and suction changes, such as those generated in tunnels by passing vehicles (trains, cars, etc.). The materials and fasteners installed there must withstand a constant alternation of "pushing" and "pulling".

We therefore test construction materials such as noise protection cladding, fire protection wall cladding, fans, doors and cable ducts as well as their fastenings for strength under constant pressure and suction changes and the associated deflections.

Our final test report contains a description of the tests carried out, the test equipment and the test specimen, documentation in the form of photos and, if applicable, drawings, notification of the test result and presentation of the measurement data for individual load cycles.
