These tests do not include any provision for testing seals that may be involved in packaging applications. VAC-V2 can be used to measure gas permeability rate, solubility coefficient, diffusion coefficient and permeability coefficient at various temperature of plastic films, laminated films, high barrier material, sheets, foils, etc.

The gas transmission rate is affected by conditions not specifically provided for in these tests, such as moisture content Note 2plasticizer content, and nonhomogeneities.

VAC-V2 Gas Permeability Tester VAC-V2 can be used to measure gas permeability rate, solubility coefficient, diffusion coefficient and permeability coefficient at various temperature of plastic films, laminated films, high barrier material, sheets, foils, etc. Sign Up For Our Newsletter.

Ask for more details or tell us your test requirements. Correlation of measured values with any given use, such as packaged contents protection, must axtm determined by experience.

This test method provides for the determination of 1 gas transmission rate GTR2 permeance, and, in the case of homogeneous materials, 3 s1434. Link to Active This link will always route to the current Active version of the standard.

Referenced Documents purchase separately D144 documents listed below are referenced within the subject standard but are not provided as part of the 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.

No other units of measurement are included in this standard.

ASTM D Standard: Gas Permeability Tester for Plastic Film and Sheeting

The materials being tested often affect the between-laboratory precision. Even in essentially homogeneous structures, variations in morphology as indicated, for example, by density and thermal history may influence permeability.
