Pressure Test
A test performed on pressure vessels that have been in service and that have undergone an alteration or repair to the pressure boundary(s) to indicate that the integrity of the pressure components are still compliant with the original construction code. The pressure test can be hydrostatic, pneumatic, or a combination thereof. Pressure tests at less than those specified by the construction code to determine if there may be leaks in the system are generally referred to as tightness tests.
