Dynamic Water Proofness Tester
Model No. HV-EXP3564
Dynamic Water Profaneness Tester - The uppers of shoes get folded over the toe portion every time a step is taken. These repeated foldings cause the finished grains to start cracking, resulting in loss of water resistance. To ensure that the leather uppers retain their water resistance for a reasonable period of use, the action of such foldings on them is evaluated by subjecting test specimens taken from the leather to a water penetration test using a penetrometer. & In this apparatus the test specimens are held in form of a trough between two cylindrical grips. One of the grips is then repeatedly moved towards and away from the other along their common axis. The test specimens are kept immersed in a water bath up to a part of their periphery. Penetration is detected when an electric conductivity is established between the inside and outside surfaces of the test specimens. civil lab equipments manufacturers.
