    🔬 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 is measured to detect leakage.
