Water Penetration Tester Description
This tester can add water pressure in constant rate on tarpaulin, when water drop penetrate from tarpaulin, at this moment the pressure is hydrostatic pressure characteristic of tarpaulin.
1. Water pressure method: Water level increase at speed of 1cm/sec. When three points penetration happen, record the highest level. (this is the most common method)
2. Fixed water pressure method: Water level increase to a particulate level at speed of 1cm/sec. record the time when three points penetration happen.
3.Leakage method: Water level increase to particular level and stop immediately and then observe how much water leaking (ml) within regulative period.
