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. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...
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 leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
In 2002, Aeroflex acquired IFR Systems Inc, a test equipment manufacturer from Wichita, Kansas, originally founded in 1937.

Hydrogen leak testing is the normal way in which a hydrogen pressure vessel or installation is checked for leaks or flaws. This usually involves charging hydrogen as a tracer gas into the device undergoing testing, with any leaking gas detected by hydrogen sensors. [1] Various test mechanisms have been devised.
One, the pneumatically-actuated "clamshell" test fixture, electrically probes a circuit board from both sides. The company also combined in-circuit test with functional test in the same test fixture in 2004, by developing (and patenting) the two-stage fixture having pins of two different lengths, and compressing to two different heights.

VTI Instruments Corporation sells precision instrumentation for electronic signal distribution, data acquisition and monitoring. [1] The company's products are used to automate the functional testing of complex electronic systems as well as to monitor and record data that characterizes the physical integrity of aircraft, engines, and other large structures.
