THe hydrostatic head tester model WP 35S allows to determine the waterproof limits of fabrics
The Standard UNI EN ISO 811:2018 describes the procedure to perform the test of resistance to water penetration
Samples analyzed with WP 35S are mainly technical textiles, bonded fabrics, coated fabrics, waterproof membranes and other textile materials resistant to water penetration.
The test method according to UNI EN ISO 811:2018 establishes the hydrostatic head limit of fabrics at a passage of waterdrops across the specimen subjected to constant pressure increase of cm.H2O/min.
Original test area is 100 cm2 (UNI 20811), but can be applied on 100 cm2 add-on reductions in compliance with AFNOR Standard.
The hydrostatic head tester is equipped with a pneumatic clamping system with On/Off switch that apply always same force on sample ensuring a perfect tightness of the specimen during hydrostaic head test.
