ASTM F 1769 : 1997

CONTAINED IN VOL. 15.09, 2001 Covers the measurement of volatile organic-vapor-barrier properties of coated papers, films, laminates and plastic sheeting. The specific material properties measured include permeability coefficients, solubility and diffusivity; parameter values which are required for the solution of mass transfer problems associated with non-steady state and steady state conditions.

1.1 This test method covers the measurement of volatile organic-vapor-barrier properties of films, plastic sheeting, coated papers, and laminates. The specific material properties measured include diffusivity, solubility, and permeability coefficients; parameter values which are required for the solution of mass transfer problems associated with nonsteady state and steady state conditions.

1.2 Applicable test vapors include volatile organic compounds which are detectable by a flame ionization detector. Examples of applicable permeation compounds include solvents, organic film additives, flavor compounds, and aroma compounds.

1.3 This test method assumes the material being measured exhibits Fickian behavior and uses the solutions to Fick's Laws for a planar surface as the data regression model. (See Annex A1.)

1.4 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.
