Hydrostatic testing is a pressure test preformed on objects to determine strength and leakages, with a liquid, usually water. Hydrostatic testing is the most common method for testing. During the Hydro test the object will be filled with water, the object is pressurized to a certain level for a specific amount of time, based on customer or industry requirements. Acceptance of the test is based on the ability of the material under test to hold the specified pressure without deformation of the material or leakage.
