The Hydrostatic Pressure Tester determines the resistance of textile fabrics to penetration by water. At a constant rate of increasing pressure. The Hydrostatic Pressure Tester tests quality of fabrics to resist water. It does by measuring the flow of water through the material.
The testing procedure starts with subjecting the testing specimen to water. And thereafter, increasing pressure of water on one side. This is under standard conditions. Only until penetration occurs in three different places. then record the hydrostatic pressure at which water penetrates the fabric at the third place.
