Check that the method can detect a known challenge
A representative intact pack shows the normal baseline for the chosen setup. A positive control has a known path or a characterized reference leak. It checks that the same setup can detect a challenge relevant to the acceptance decision. A large open hole may trigger the instrument easily while a narrow channel near the intended limit goes undetected.

Match the challenge to the package and method
Select a control whose flow behavior or defect geometry relates to the expected package failure. Keep pressure, orientation and fill conditions comparable, and repeat the runs to check separation from the intact samples. A calibrated reference leak can check the response of the instrument, while a representative defective pack can also challenge sample handling and fixture effects.
Record the control and the conditions under which it was detected. Passing a system check establishes a response to that challenge. It leaves other defect types and the production defect rate to separate evaluations.
