A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks.
A hydrostatic test involves pressurising the cylinder to its test pressure (usually 5/3 or 3/2 of the working pressure) and measuring its volume before and after the test. A permanent increase in volume above the tolerated level means the cylinder fails the test and must be permanently removed from service. [3]: sect. 5.7.3
A process to perform a water flow test is explained in the model fire codes as published by NFPA (National Fire Protection Association). If a water supply source is considered weak compared to what is required by the sprinkler system design hydraulic calculation , the water pressure can be boosted by means of a fire pump .
The most common leak detection method for pipeline operators is called the Supervisory Control And Data Acquisition (SCADA) system. This system uses a series of sensors to track data such as pressure, flow rates, temperature, and whether valves are open or closed.
where is the height z − z 0 of the liquid column between the test volume and the zero reference point of the pressure. This formula is often called Stevin's law. [ 4 ] [ 5 ] One could arrive to the above formula also by considering the first particular case of the equation for a conservative body force field: in fact the body force field of ...

The low-end test equipment is dominated by few large suppliers, notably Germany's Loviband and Merck, DelAgua & ITS Europe Water Testing of the UK who work globally, and US-based LaMotte. Major manufacturers of in-line equipment include Siemens and Danaher's Hach. Thermo Scientific and Waters are key producers of high-end test equipment. [38]
