    Fabric Hydrostatic Tester ISO 811 Fabric Hydrostatic Head ...
    The EN20811 Hydrostatic Head Pressure Tester measures the water resistance of coated fabrics, tents, rainproof clothing, and geotextiles by applying rising water pressure. It conforms to standards including BS EN 20811, ISO 811, and AATCC 127, determining when the third water droplet penetrates the sample.

    Key Features and Specifications 
    • Standards: Complies with BS EN 20811, ISO 811, AATCC 127, GB/T 4744, and JIS L 1092.
    • Test Methods: Offers dynamic, static, and customized test programs.
    • Measurement Range: Typically
      500𝑃𝑎
      ∼200𝑘𝑃𝑎
       (or custom ranges, e.g.,
      0
      ∼5000𝑚𝑏𝑎𝑟
      ).
    • Accuracy: High-precision pressure sensors with automated testing processes.
    • Data Management: Digital display with options for printing results or USB/computer connectivity for data logging. 
    Testing Process 
    1. Preparation: The sample is clamped securely over a test hole.
    2. Pressurization: The instrument applies rising water pressure to one side of the fabric at a specified rate.
    3. Observation: The tester automatically detects or requires manual observation of water penetration.
    4. Result: The pressure at the point of failure is recorded, often defined by the appearance of three separate droplets (ISO 811). 
    Common Applications 
    The EN20811 tester is utilized for: 
    • Outdoor sports clothing and hiking gear.
    • Medical non-woven fabrics and protective clothing.
    • Industrial materials: Tents, tarpaulins, canvas, and geosynthetics.

    What is the hydrostatic head test ISO 811?
    The hydrostatic head supported by a fabric is a measure of the opposition to the passage of water through the fabric. A specimen is subjected to a steadily increasing pressure of water on one side of the fabric, under standard conditions, until penetration occurs in three places.

    What is the standard for hydrostatic pressure test?
    ASME B31.

    The hydrostatic test pressure at any point in the piping system shall not be less than 1.5 times the design pressure, but shall not exceed the maximum allowable test pressure of any non-isolated component, nor shall it exceed the limits of calculated stresses due to occasional loads.
