    Testing Principles

    Pressure Decay Method: Inflate the workpiece → Maintain pressure → Measure the pressure drop value. The greater the pressure drop, the greater the leakage.

    Differential Pressure Method: Compared with standard sealing components, the pressure difference between the workpiece and the standard component.
