Hydrostatic head tester determines the resistance of fabrics to water penetration

Samples of fabrics analyzed with Hydrostiac head tester 35S are technical textiles, bonded fabrics, coated fabrics, impermeable membranes and other materials resistant to water penetration.

Test method establishes the minimum hydrostatic pressure that enduces to a passage of water across the specimen subjected to constant head increment.

Original test surface is of 100 cm2 (UNI 20811), but can be applied on 100 cm2 other reduction flanges in compliance with AFNOR Standards.

The Hydrostatic head tester has a pneumatic closure with activation switch on front panel that assures the perfect tightness of the specimen during the test running.
