This article describes a calculation procedure of a permissible leakage flow for sealed products. It is shown how a leak detector sensitivity can be improved by changing a pressure drop and a test gas. Optimal leak rate ranges for a mass spectrometric leak detector, a portable helium leak detector and a pressure decay leak detector are suggested in order to achieve high accuracy, repeatability and minimum test expenses.
