    Determination of material resistance to water penetration by hydrostatic pressure according to DSTU EN 20811

    Testing the resistance of a material to water penetration by hydrostatic pressure allows you to determine at what pressure water begins to penetrate through fabric or other materials.
    This indicator characterizes the water resistance of the material and is a key criterion for assessing the quality of products designed to protect against moisture — clothing, tents, medical barrier materials, technical and special clothing, and textiles.

    Tests are conducted in accordance with the requirements of DSTU EN 20811:2017 (EN ISO 811:2018). During the test, the material sample is secured in a chamber, which is supplied with water with a gradual increase in pressure until the first three drops appear on the surface of the sample. The resulting hydrostatic pressure value (in mm of water column or Pa) is recorded automatically and used to assess the water resistance of the material. Tests can be performed at water pressures from 0 to 3000 cm Н₂О in accordance with DSTU EN 20811:2004, EN ISO 811:2018.
