Hydraulic, pneumatic and hydrostatic testing
validate the strength and reliability of your equipment
Hydraulic, pneumatic and hydrostatic testing is a critical technical tool for assessing the structural strength and functional behaviour of equipment subjected to pressure loads that are generally severe, sometimes cyclic and often combined. They are used for design validation, but also at the regulatory approval stage.

Why carry out hydraulic tests?
Our tests enable us to assess the behaviour of a piece of equipment under actual conditions of use, or under severe conditions by applying hydraulic stresses:
- Mechanical strength under pressure (burst and proof pressure).
- Behaviour under pressure pulses (water hammer).
- Equipment operation (characterization tests).
- Hydraulic fatigue resistance.
- Verification of resistance to pressure and temperature cycles.
- Reproduction of real or severe conditions for the automotive, rail, aeronautical and defence industries...
What sectors are involved in these trials?
