What is the Hydrostatic Head Tester In Fabric

A. What is Hydrostatic Head?

Hydrostatic Head is a way of measuring how waterproof a fabric is. The resulting measurement in millimetres relates to how high a column of water standing on the fabric would need to be before the water would penetrate the fabric. For the best fabrics results can be as high as 30,000mm, i.e. 30 metres high, before it would penetrate the fabric.

B. Hydrostatic Pressure

The Hydrostatic Pressure test evaluates a material’s resistance to water penetration. The test is done using a machine that replicates the downward pressure that a water column of such height would create. The machine increases the pressure of water that is pushed against the fabric until water is visible on the other side. The required level of pressure used to force water through the fabric is then converted into a measurement of how high the water column would have been. This provides the result of the Hydrostatic Head test in millimetres.


C. WHAT IS A HYDROSTATIC HEAD TESTER?

A Hydrostatic Head Tester is a measuring device used to measure the water penetration resistance of fabrics and seams. It provides quick and accurate results.

Digital Hydrostatic Head Tester is used to testing the waterproof properties of fabrics through waterproofing work such as canvas, coated fabrics, hood fabric, tarpaulin, rain-proof fabrics and geotextile.

D.The Feature Of High Pressure-Servo Hydrostatic Pressure Test Equipment

1. The pressure using dynamic feedback regulation effectively prevent pressure overshoot.
