发明名称 Method for measuring permeability of a material
摘要 A method for measuring the permeability of a gas through a material, wherein the steps include exposing the material to the gas to be measured and measuring the outgassing characteristics of the material over increments of time, to develop exponential expressions representative of the measured amounts, and solving the exponential expressions for the diffusion coefficient D and the solubility coefficient S; and then calculating the permeability of the material by forming the product of the diffusion coefficient D and the solubility coefficient S.
