Helium Leak Testing

Leak testing is employed to detect leaks and determine the rate at which a
fluid i.e. a liquid or gas will penetrate from inside a tight component or
assembly to the outside or vice versa as a result of pressure differential
between the two regions or of permeation of somewhat extended barrier. It
has become conventional to use the term “leak” to refer to an actual
discontinuity or passage through which a fluid flows or permeates. “Leakage”
refers to the fluid that has flowed through a leak. “Leak rate” refers to the rate
of fluid flow per unit of time under a given set of conditions, and is properly
expressed in units of mss per unit of time. Standard leak rate refers to the rate
of flow o atmospheric air under conditions in which inlet pressure is 0.1 Mpa
±5%; outlet pressure is leass tha 1 Kpa; temperature is 298K±5 and dew point
is less than -298K.
The term “minimum detectable leak” refers to the smallest hole or discrete
passage that can be detected and “minimum detectable leak rate” refers to
the smallest detectable fluid flow rate. The amount of leakage required for a
leak testing instrument to give a minimum detectable signal can be
determined. This amount is generally used to denote the sensitivity of the
instrument. Instrument sensitivity is independent of test conditions, but when
an instrument is applied to a test, the sensitivity of the test depends on the
existing conditions of pressure, temperature and fluid.
