摘要：Apparatus for measuring the permeability of a material to passage of a fluidincludes a pressure regulator for varying the pressure of a supplied fluid, a pair of jawswhich may be clamped onto the material specimen, a solenoid valve arranged betweenthe regulator and the jaws, and a collapsible container arranged to be inflated with suchfluid as may pass through the clamped specimen during the test. The permeability of thetest specimen is determined in terms of the length of time needed for a known volumeof such fluid to pass through the specimen, when fluid at a test pressure is applied to aunit area thereof. The apparatus may further include a pressure switch arranged to sensean inflated condition of the container, and a timer to disable the apparatus until sufficienttime has been provided to enable the container to return to its deflated condition. In use,such apparatus performs an improved method of measuring the permeability of thematerial to passage of such fluid.
