GW-313 Tablet seepage machine
The instrument is mainly used to determine the upper water permeability and water absorption. The main materials used for the uppers: leather, imitation leather, cloth ... etc., and cut the standard test piece, the device on the test machine, the water in the external conditions, the angle of the standard rate and scratch off the action, Flexing some time after sensing material penetration index as the basis for the development of improved waterproofing material.
Standard: GB/T20991-2007, 6.13
Note: This test is done with the weighing scales needed to complete specific gravity (gravity balance GW-044D sold separately!)
