Abstract
A method and system of testing a tightness of a closed container using a two-part test. The first part of the two-part test includes connecting the closed container to a gas supply and filing the closed container with a testing gas from the gas supply. A first leak rate of the closed container is measured over a first period of time, and when the first leak rate is less than a first threshold, the controller identifies the closed container as compliant. Conversely, when the first leak rate is greater than the first threshold, the controller measures a second leak rate of the closed container over a second period of time. When the second leak rate is greater than a second threshold, the controller identifies the closed container as noncompliant, and when the second leak rate is less than the second threshold, the controller identifies the closed container as compliant.
