2. Place the sample in the armature, rotate the armature and confirm;qz3Textile Testing Instruments, Testing Equipment Manufacturer

3. Press the up button and the metal container with 700 ml of water will start to rise at a constant speed driven by the motor. Increase the water pressure on the sample in the fixture;qz3Textile Testing Instruments, Testing Equipment Manufacturer

4. Observe the color change of the indicator paper covered on the filter paper sample through the plastic window of the fixture to measure the penetration of water;qz3Textile Testing Instruments, Testing Equipment Manufacturer

5. When the first signal of the color change of the indicator paper (from blue to pink) appears, immediately read the height of the water level on the ruler, expressed in Pa (mmH20);qz3Textile Testing Instruments, Testing Equipment Manufacturer

6. Press press the up button again to make the metal. The container stops rising and the measurement is recorded as the test data of the water resistance of the filter paper; qz3Textile Testing Instruments, Testing Equipment Manufacturer

7. Open the fixture, take out the sample and indicator paper, dry the loading window of the fixture with a soft cloth and check the water level in the fixture;qz3Textile Testing Instruments, Testing Equipment Manufacturer
