Leakage Requirement

Description
There are a variety of satellites, each with a specific function and supporting a specific aspect of our daily life. It can be used to enhance navigation, GPS or internet communication; to monitor tides; or to forecast weather. In order to link with each function, a satellite carries instrumentation that needs to operate for many years since maintenance is not possible on a satellite. Instrumentation also needs to be protected from the outside atmosphere, all of which are possibly detrimental, as well as internal corrosive fluids and substances that are carried by the satellite for its other functions (such as hypergolic fuels that power its thrusters).

Description
Launch vehicles are most often propelled using fluids with liquid oxygen being the most common oxidizer and fuel being liquid hydrogen or kerosene and most recently liquid methane. All these fluids (except kerosene) are commonly stored at cryogenic temperatures.
Sealing is critical when liquid oxygen or hydrogen are involved since they are easily ignitable. Any small amount of leakage can create a hazardous situation, which can lead to a potential explosion of the whole launch system. Leakage requirements are therefore quite stringent.
