MONTE CARLO METHOD APPLIED TO GRAVIMETRIC LEAK CALIBRATION

B. Blanc, F. Beaudoux

Abstract

The gravimetric method for standard leak calibration is already documented and has proven to be repeatable. However, neglecting the air buoyancy correction in some cases may lead to a significant increase of the uncertainty and a bias on the result. The aim of this work is to provide a method for atmospheric leaks calibration using simple mass comparisons and the Monte Carlo method in order to determine the associated uncertainty and check the validity of the GUM approach in specific cases. The main objectives are to provide a guideline on how to quickly and simply calibrate such equipment and take into account the air buoyancy correction despite the lack of knowledge about the standard leak density.
