ISO 20344 Water Vapor Permeability Tester for Footwear Upper
Material
1．Product Name: Water vapor permeability tester
2.Description:
This machine tests the characteristics of moisture permeability of
the upper and upper shoe (including leather and lining) in the
environment of 20℃and 65% RH specified in the specification.
Test principle: The specimen is fixed on the opening of a test
bottle equipped with a certain amount of solid desiccant. Put the
test bottle in the strong air environment, move the bottle so the
desiccant move constantly, so as to drive the air continued to be
disturbed, weighing the test bottle, measure the weight of water
vapor absorbed by the desiccant.
3. Test Standard: ISO 20344, ISO 8782-1, ISO 17699
