🔬 Testing Principles
1
Pressure Decay MethodInflate the workpiece → Maintain pressure → Measure the pressure drop value. The greater the pressure drop, the greater the leakage.
2
Differential Pressure MethodCompared with standard sealing components, the pressure difference between the workpiece and the standard component is measured to determine leakage.
