Historical Standard: ASTM D3985-02 Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor
SUPERSEDED (see Active link, below)
ASTM D3985
1. Scope
1.1 This test method covers a procedure for determination of the steady-state rate of transmission of oxygen gas through plastics in the form of film, sheeting, laminates, coextrusions, or plastic-coated papers or fabrics. It provides for the determination of ( 1 ) oxygen gas transmission rate (O 2 GTR), ( 2 ) the permeance of the film to oxygen gas (PO 2 ), and ( 3 ) oxygen permeability coefficient (P'O 2 ) in the case of homogeneous materials.
This standard does not purport to address all of the safety problems, 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.
1.2 This test method does not purport to be the only method for measurement of O 2 GTR. There may be other methods of O 2 GTR determination that use other oxygen sensors and procedures.
