Test Procedure

1. Activate the water‑inlet pressurization device to allow water to enter and fill the collection tank slowly, until it is just about to overflow.

2. Place the specimen, free of wrinkles, flat on the mesh inside the water collector, and allow excess water to drain off to ensure there are no air bubbles in the collector. Cover with the porous plate and clamp the specimen evenly. For specimens composed of a textile material laminated to a membrane, orient the membrane side toward the water surface. For composite materials with textile layers on both sides and the membrane sandwiched in the middle, carefully peel away the edge of the textile layer facing the water surface from the annular portion to be clamped; alternatively, apply a sealant such as glass adhesive to the clamped annular section to ensure that the clamped area remains watertight.

3. Slowly adjust the pressurization device to increase the water pressure in the collector to 0.1 MPa; if the approximate range of the sample’s hydrostatic pressure resistance can be estimated, the pressure may be set directly to the lower limit of that range to begin the test.

4. Maintain the aforementioned pressure for at least 1 hour, and observe whether any water leaks out of the wells in the microtiter plate.

5. If the specimen does not exhibit water penetration, incrementally increase the pressure in steps of 0.1 MPa, maintaining each pressure level for at least 1 hour, until water leakage occurs. At that point, the specimen is considered to have a water‑permeable defect or to have sustained rupture. Record the pressure value immediately preceding the onset of leakage; this represents the specimen’s hydrostatic pressure resistance, reported to an accuracy of 0.1 MPa.

6. If it is only necessary to determine whether the specimen has reached a specified hydrostatic pressure, the pressure may be increased directly to that value and maintained for at least 1 hour. If no water leakage occurs, the specimen is deemed to meet the requirements. When water droplets appear in the pores of the porous plate, if wiping them away results in no further leakage, this can be attributed to edge overflow and the test may proceed. However, if leakage persists after wiping, it indicates water penetration through the specimen, and the test may be terminated.

7. Determine the remaining specimens according to steps 4.1 through 4.6. Ensure that three valid data points are obtained, and that the difference between the two lowest values does not exceed 50%; otherwise, an additional 2–3 specimens should be tested.

8. Determine whether seepage is occurring by monitoring the seepage rate. Under a given hydraulic head difference, if the seepage rate is extremely low (e.g., less than 0.1 cm³/h), it can be considered that no seepage is present; conversely, a rapid increase in the seepage rate indicates that the specimen has failed, and the test may be terminated.
