  • Aircraft O2 Cylinder Hydrostatic Testing & Filling ...

    2020-11-6u2002·u2002The most common method is a water jacket volumetric expansion test, also called a hydraulic proof pressure test. The vessel (O2 cylinder or bottle) is filled with water and placed within a water jacket. The vessel is then pressurized with water to the rated test pressure. As the vessel expands under the pressure, it displaces water from the jacket.
