1.1 This Standard describes a method covering the estimation of the steady-state rate of transmission of a gas through plastics in the form of film, sheeting, laminates and plaslic-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.
1.2 Two procedures are provided.
1.2.1 Procedure M - Manometric.
1.2.2 Procedure V - Volumetric.
1.3 Caution. This Standard may involve hazardous materials, operations, and equipment. This Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever using this Standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
