Standard Method for Determining Gas Permeability Characteristics of Plastic Film and Sheeting
|Publication Date:||30 July 1982|
|ICS Code (Films and sheets):||83.140.10|
This method covers the estimation of the steady-state rate of transmission of a gas through plastics in the form of film, sheeting, laminates, and plastic-coated papers or fabrics. This method provides for the determination of (1) gas transmission rate (GTR), (2) permeance, and, in the case of homogeneous materials, (3) permeability.

The values stated in SI units are to be regarded as the standard.
