ABSTRACT:
A test cell comprises a first enclosure which is closed at one end and open at the other. A fan is located near the closed end for supplying conditioned air to the first enclosure and an aperture in the bottom wall of the enclosure near its open end. An apertured sample holder may be used to hold the test specimen in place during use. The first enclosure is preferably divided into first and second compartments by a slotted divider. The test cell may optionally include a baffle near its closed end to reduce eddying of the air and to provide a uniform air flow pattern across the test specimen. The test cell of the present invention may be used in conjunction with the apparatus described in U.S. Pat. No. 4,357,827 to measure moisture vapor transmission characteristics of a test specimen.
