  • How to Establish an Acceptable Leak Rate - Leak Testing

    • The characteristics of the hole (or leak) that determine whether it will leak are the smallest diameter in the hole path, the path length of the hole through the part material, surface tension, and the surface finish of hole (leak). Hole Size - The smallest opening in the flow (leak) path controls the rate of flow through the path.

  • Leak Rate - an overview | ScienceDirect Topics

    The leak rate may be defined in terms of the fall in pressure in the vessel. (19.8.1) L = − V d P d t. where L is the leak rate (Pa m 3 /s), P is the pressure (Pa), V is the volume of vessel (m 3 ), and t is the time (s). Until quite recently, the internationally agreed unit of leak rate has been the torr l/s (=0.133 Pa m 3 /s).

    Pressure drop tests allow leak rate measurements to 10-4 mbar*l/s but results can be distorted if condensation occurs. As one can see, the differential pressure decay test is fraught with caveats, but if employed under laboratory conditions, it is a good tool at determining both leaks and leak rates.

  • Leak Standards FAQ - LACO Tech

    For example, if a leak standard has a calibrated leak rate of 2.00 x 10-7 cc/sec and its uncertainty is ±10%, the true leak rate is likely between 1.80 x 10-7 and 2.20 x 10-7 cc/sec. NOTE The uncertainty is an expression of the calibration uncertainty, and is a function of the calibration process, not a physical property of the calibrated leak standard.
