It is one of the hydro-testing machines, widely applied for determining the resistance of fabrics (canvas, coated fabrics, cover cloth, rainproof clothing fabrics, and geotextile materials) and films to water penetration under pressure. Hydrostatic Head Tester TF163C complies with testing standards like AATCC127, ATSC127-2008, EN 20811, ISO 811, etc. Please contact us for the Hydrostatic head test(water penetration test) procedure,and get the hydrostatic head tester price.Our hydrostatic tester for sale.
Description
Application
Hydrostatic Head Tester TF163C is also named Hydrostatic Pressure Testing Machine TF163C. It can measure the water penetration resistance of fabrics under hydrostatic pressure by clamping the specimen on a standard test area. The hydrostatic test can include those kinds of fabrics, such as canvas, coated fabrics, cover cloth, rainproof clothing fabrics, geotextile materials, and films to water penetration under pressure while firmly clamped in the test rig of standard area. When you have a hydrostatic pressure testing machine, you can do a hydrostatic head test easily. A More smart and advanced version of the hydrostatic pressure tester machine developed by our sister company ChiuVention.

Know More about Hydrostatic Head Tester
Definition of hydrostatic pressure
Hydrostatic pressure refers to the resistance encountered when water passes through the fabric. The fabric is subjected to a continuous rise in water pressure until water beads up on the back of the fabric under standard atmospheric pressure. At this point, the measured water pressure value is the hydrostatic pressure. The greater the hydrostatic pressure that the fabric can withstand, the better the waterproofness or resistance to seepage.
Hydrostatic pressure units
The hydrostatic pressure can be expressed in N/㎡, Kpa, and water column height m. And the conversion unit is 1m water column height equals 9.82Kpa.
Hydrostatic head rating
Hydrostatic Head, given in millimeters. It’s a measure of how waterproof a fabric is, based on the water pressure it can withstand – the higher the number, the more waterproof the fabric. Contact us to acquire more detailed hydrostatic head rating parameters about this hydro pressure tester.
Precaution and Maintenance
1 Before the first operation, the operator must read the Operation Manual carefully and receive special technical training.
2 Sweep the upper chuck lightly before placing the specimen to avoid affecting the test results.
3 The default value of the cylinder is 0.5MPa (can be adjusted according to the characteristics of the specimen). The maximum error range should not exceed plus or minus 0.2MPa.
4 The inlet pressure should be less than 0.8MPa but the maximum pressure should not exceed 1MPa.
5 Turn off the power and then remove the plug from the power outlet after each test.
6 Emergency stop and restart the instrument in case of malfunction.
7 In order to ensure the normal operation of the machine, the user must regularly check the water level of the test tank. Meanwhile, drain the water out if the machine will keep idle for a long time. You, therefore, need to turn on the drain switch (horizontal direction to the outlet pipe) and by all means, avoid wetting the electrical equipment. After completing the drainage, close the drainage switch (vertically to the outlet pipe) and check that the drainage switch and the pipe mouth must not fall off.
8 Keep the touch screen away from sharp hard objects.
9 No strong electromagnetic interference in the surroundings.

What is the hydrostatic head tester:
The definition of hydrostatic head is the pressure of homogeneous fluid act on an object, which can explain that each part of an object is forced uniformly. The object will shrink its volume when the hydrostatic pressure is enhanced but will not change.
Hydrostatic head test procedure:
- Turn on the power.
- Turn on the air pump and adjust the air pressure governor to ensure that air pressure in a reasonable range.
- Pouring water into the water tank until it reaches the highest water level.
- Setting and saving the parameter on the setting page according to the standard, go to the test page.
- Place the sample on the clamp to fix it, and then put the sample into
Attention: The pressure transducer should be zeroed or cleared. Otherwise, the test result might be inaccurate.
- Start the test and observe the sample.
- he third water droplet has appeared on the surface a we should stop the test and record the data.
- After that, we need to release the sample and change another one for the next test.
- Draining the water after all the test is finished, and turn the power off.
A: Hydrostatic pressure refers to the water permeability of fabrics under certain water pressure. It is suitable for all kinds of fabrics, including those treated with waterproofing.ydrostatic pressure method is used to measure the waterproofing offabrichere are static pressure methodand dynamic pressure method. Static pressure is used for water-conducting fabrics, and dynamic pressure is used for coated or compact fabrics.
A: Yes, it is.
Q: What is the difference between hydrostatic head testing and air permeability testing towards fabrics?
A: Hydrostatic pressure test measures the waterproofness of a fabric by using Hydrostatic Head Tester, while air permeability testing assesses the ability of a fabric to circulate air by using an air permeability tester. The two usually need to be considered together in developing waterproof fabrics to ensure that they are both waterproof and breathable.
Q: Does a high hydrostatic pressure value mean the fabric is more waterproof?
A: Yes, a higher hydrostatic pressure value indicates better waterproof performance, meaning the fabric can prevent water penetration under greater water pressure.
Q: What are the reasons for a decrease in hydrostatic pressure testing value?
A: Factors such as prolonged use, frequent washing, coating wear, or fabric aging can lead to a reduction in the hydrostatic pressure value, thereby affecting its waterproof performance.
Q: How to determine the endpoint of the fabric hydrostatic pressure test?
A: The endpoint is reached when the third water droplet appears on the surface of the sample in the hydrostatic pressure testing machine. The water pressure at this moment is recorded as the test result. Test personnel should closely observe the formation of water droplets and ensure timely recording of the appearance of the third droplet to obtain an accurate hydrostatic pressure value.
Q: How to avoid water leakage issues in the fabric hydrostatic head pressure test?
A: Ensure the sample is securely clamped to prevent any loosening.
Regularly check the sealing gaskets of the clamping device.
Adjust the clamping pressure to ensure a tight fit around the edges of the sample.
Q: What factors affect the hydrostatic pressure test of fabrics?
A: Yarn Thickness
For tightly woven fabrics made from moisture-absorbing fibers, the capillary effect allows for reduced yarn radius, which can enhance the fabric's resistance to water penetration.
Yarn Elasticity
Under water pressure, elastic yarns in the warp and weft can stretch, leading to gaps between adjacent yarns. This allows water droplets to pass through more easily, reducing the fabric's water resistance.
Fabric Thickness
Thicker fabrics generally have greater moisture resistance and higher water pressure values due to increased wet resistance.
Yarn Density
Increased distance between yarns directly affects water resistance. Typically, the tighter the fabric structure, the better its water penetration resistance.
