ABSTRACT:
A material whose permeability to a fluid, such as a gas, is to be measured, forms at least part of the wall of a chamber which is otherwise impervious to the fluid, and the fluid is located within the chamber at a reference pressure level. In one embodiment, after a given interval of time, sufficient fluid is returned to the chamber to restore the pressure to its reference level. The volume of fluid required is a measure of the permeability of the material.
