WebPermeation, Permeance, Water Vapor Permeability Converter. Permeation, in physics and engineering, is the penetration of a permeate (such as a liquid, gas, or vapor) through a solid, and is related to a material’s intrinsic permeability. Permeability is tested by permeation measurement, for example by a minipermeameter. WebMOCON Permeation Testing Analyzers are recognized as the industry-leading solution for over 50 years and are the basis for many global permeability testing standards such as ASTM D3985 and ASTM F1249.
