| Abstract: | This paper discusses the theory and models of materials outgassing. Theoretical outgassing rates of typical (cylindrical) testing products are obtained by using Fick's law. Two methods of measuring the outgassing rate are proposed, which are the constant volume method and the orifice throughput method. Three problems of the orifice throughput method are analyzed and solved by the twin gauge throughput (TGT) method. |
