    Abstract: A system and technique for pressure testing a line portion, connection, or other linking piece of unknown leak characteristics. The technique includes applying predetermined pressure to the linking piece to be tested as well as to another of known non-leaking characteristics. Thus, a differential of recorded pressures may be monitored over time and against a predetermined known parameter. For example, an acceptance boundary with a set level of confidence may be established against which the differential may be evaluated. The boundary may be developed by prior testing of known non-leaking characteristics.
