Phạm vi áp dụng / Scope of standard

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 (P'CO₂) , and (3) carbon dioxide permeability coefficient (P"CO₂) in the case of homogeneous materials.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
