WATER VAPOUR PERMEABILITY AND WATER VAPOR COEFFICIENT

WATER VAPOUR PERMEABILITY  AND WATER VAPOR COEFFICIENT
Product Description

Water vapour permeability of leather is evaluated by clamping a circular test specimen over the mouth of a bottle containing a solid desiccant and subjecting it to a rapid current of air. The air inside the bottle is circulated by keeping the desiccant in motion. The increase in weight of the bottle over a specified interval of time gives the quantitative measure of the water vapor permeability of the leather sample under test.
