Abstract: A portable system (100) for testing a valve (3) in a process plant. At least one upstream (102) or downstream (104) connector permits fluid contact to a respective upstream isolation valve (2) or a downstream isolation valve (4). A summation technique enables detection and quantification of a small leakage (20, 40) through either isolation valve (2, 4) during testing or certification of the valve (3). A portable computer (110) runs a controller (120) for automatic testing or certification. The controller (120) supports branching into separate diagnostic routines depending on measurements from sensors (122, 124). A security system (130) ensures reliable and confidential measurement data, and facilitates certification. Areas of use include chemical factories, offshore platforms for producing hydrocarbons and treatment plants aboard ships.
