VAC-V1 Gas Permeability Tester VAC-V1 is applicable to the determination of gas permeability rate, solubility coefficient, diffusion coefficient and permeability coefficient at various temperature of plastic films, laminated films, sheeting, foils and finished packages, etc.

The materials being tested often affect the between-laboratory precision.

Historical Version s – view previous versions of standard. It is equipped with three diffusion cells. It is suggested that this method not be used for referee purposes unless purchaser and seller can both establish that they are measuring the same quantity to a mutually agreed upon level of precision.

The causes of these variations are not known at this time. No other units of measurement are included in this standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

VAC-V3 Gas Permeability Tester VAC-V3 is designed for the measurement of gas permeability rate, solubility coefficient, diffusion coefficient and permeability coefficient at various temperature of plastic films, laminated films, high barrier material, sheets, foils, etc. This test method provides for the determination of 1 gas transmission rate GTR2 permeance, and, in the case of homogeneous materials, 3 asym.

Even in essentially homogeneous structures, variations in morphology as indicated, for example, by density and thermal history may influence permeability.
