Abstract
A process to measure the moisture permeability between a liquid and a solid body is described, which is of importance for determining the suitability of material combinations. In the course of the process, the oscillation behavior of an oscillating system is changed when a solid body or test object is immersed in a liquid by the interaction of surface tension forces between the surface of the solid body or test object and the fluid. The change in the oscillation behavior or the transfer of oscillation energy between the solid object and the fluid is then used as an indicator of the strength of the surface tension force.
