This paper describes a method for measuring hydrogen permeabilities of plastic films and metal foils. The method utilizes a hydrogen mass spectrometer leak detector.Hydrogen permeability values of several plastic films are presented over a temperature range of 250 to -150 F. The experimental work was done as part of an evaluation of cryogenic insulation systems to be used in space vehicles.
