Water Proofness Tester For Testing Lab Workshop.
Water Proofness Tester - For Testing Lab
The water proofness Tester for leather for shoe uppers consists of a set
of acrylic cylindrical grips, half of which are fixed while the
remaining half are movable along their common axis. The movement to the
grips is give with the help of a motorized arrangement through a worm
reduction gearbox. The travel of moving grip, which is different for
different leathers, can be set at any one of the four specified values
by changing the cam fitted on the gearbox.
The grips are located
inside a rectangular water container. The container can be filled with
water upto the desired level after fixing the test specimens. An
overflow pipe is provided to keep the level of water at a predetermined
height. A draining arrangement is also provided to empty out the
container at the end of the test.
Each of the test
stations has a provision for setting up an electric contact between
spiral brass turnings kept inside the test specimen and the water inside
the container. As soon as the current starts flowing through this
sensing arrangement an electric signal is generated which lights up an
indicator lamp to signify the failure of the test specimen. The test can
be continued after failure is established to determine the amount of
water penetrating through the test specimens from one face to the other
over one or more specified time intervals. The tester is available in
two models, one for testing three test specimens, and the other for
testing four test specimens simultaneously.The tester is finished in
shore blue metallic painting and bright chrome / zinc plating to give it
a corrosion resistant finish. All parts that come in contact with water
during the test are made from non-corrodible materials such as
aluminum, brass, or acrylic.
