Even in essentially homogeneous structures, variations in morphology as indicated, for example, by density and thermal history may influence permeability.
These tests do not include any provision for testing seals that may be involved in packaging applications. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
