Metrology of the leak detection practical guide


Leaks have not always been a major issue in vacuum technology where they are a limiting factor to the ultimate pressure and the purity of a process gas that can be reached in a vacuum vessel, but also in any other container, be it for operational reasons (e. g. engines, air bags or pace makers), security reasons (e. g. for poisonous or radioactive materials) or environmental reasons. Limitations of refrigerant gas leakages were pointed out in regulations to meet recommendations of the Kyoto Protocol (1997). The above mentioned examples are far from being exhaustive and the leak measurement is a crucial concern in many industries. This practical guide deals with tools and theory in the field of the gas leak detection under the view of metrology, in a range from 1 × 10-10 Pa·m3·s-1 to 1 × 10 4 Pa·m3·s-1, considering leaks towards vacuum or atmosphere. It focuses on helium leak detection and refrigerant leak detection and provides the reader with useful technical information, uncertainty assessment of helium detectors in using and knowledge about refrigerant detectors evaluation according to the European standard EN 14624 : 2012.
