Header_Umweltsimulation_Ansicht

Environmental Simulation and Vibration

External influences such as vibration, impact, cold, heat, moisture or water spray are simulated on vibration tables and in climatic chambers. We subject your product, for example, to vibration testing, shock testing, climatic testing, determination of Woehler-lines, pressure pulse tests, bursting pressure test, leak test, corrosion test and transport simulation.
