What Is Water Entry Pressure Testing?

Water entry pressure testing measures the minimum pressure required for water to penetrate a waterproof hydrophobic membrane. The test evaluates waterproof protection capability while maintaining breathable airflow performance.

Waterproof Barrier Performance

Evaluates membrane resistance against liquid water penetration and verifies reliable waterproof protection.

Hydrophobic Membrane Evaluation

Measures the water resistance capability of hydrophobic microporous membranes used in protective vent applications.

Pressure Resistance Verification

Confirms membrane durability under hydrostatic pressure conditions for demanding environments.

Ventrase Water Entry Pressure Testing Process

Ventrase evaluates waterproof breathable membranes through controlled pressure testing to determine resistance against liquid water penetration.

1. Sample Preparation ePTFE, PE, PP and composite membrane samples are prepared according to testing requirements.
2. Membrane Installation The membrane sample is securely installed to ensure accurate pressure measurement during testing.
3. Pressure Increase Water pressure is gradually increased under controlled conditions to evaluate waterproof resistance.
4. Water Penetration Detection The first appearance of water penetration is recorded as the water entry pressure value.
5. Performance Analysis Test results are analyzed together with airflow, material structure and application requirements.
