ASTM F2476 – Standard Test Method for the Determination of Carbon Dioxide Gas Transmission Rate (CO2TR) Through Barrier Materials Using an Infrared Detector

1.1 This method covers a procedure for determination of the steady-state rate of transmission of carbon dioxide gas through plastics in the form of film, sheeting, laminates, coextrusions, or plastic-coated papers or fabrics. It provides for the determination of (1) carbon dioxide gas transmission rate (CO₂TR), (2) the permeance of the film to carbon dioxide gas (PCO₂), and (3) carbon dioxide permeability coefficient (P'CO₂) in the case of homogeneous materials.
