Hydrostatic Head Tester TF163C
Hydrostatic Head Tester, used for determining the resistance of fabrics (canvas, coated fabrics, cover cloth, rainproof clothing fabrics, and geotextile materials) and films to water penetration under pressure while firmly clamped in the test rig of standard area.
For special medical protective clothing compression-folding (Schildknecht) flex cracking resistance testing, this hydrostatic head tester is also capable of doing extra tests when it fails the flex cracking resistance test, which defined in standards like EN 14126 – 2003, EN14325, EN ISO 7854.

What Criteria to Consider During Hydrostatic Testing？
1 Water temperature: water temperature directly affects the water pressure value. With higher water temperature, the measured water pressure is lower. Therefore, when testing similar products, you should choose the same water temperature.
2 The rate of water pressure rise: The current water pressure gauge typically has two rates; 10cm / minute, or 60cm / minute. The test should indicate which rate was used.
Readings: Different water pressure levels have different reading level margins for error: For 1m and below the margin for error in the water column is 0.5cm, for 1 ~ 2m, the margin is 1cm, and for 2m and above, the margin is 2cm.
3 Eliminating Bad Data:
a.No consideration for fine water drops that no longer increase after formation.
b.Consecutive water seeping in the same place of the fabric is not cumulative, it should only be counted as one drop of water.
c.If the third seepage occurs at the edge of the clamp frame and the water pressure measured at this time is lower than the lowest of the other samples in the sample, the data should be thrown out, and another sample/test should be taken.
