ASTM F1927
1. Scope
1.1 This test method covers a procedure for determination of the rate of transmission of oxygen gas, at steady-state, at a given temperature and %RH level, through film, sheeting, laminates, co-extrusions, or plastic-coated papers or fabrics. This test method extends the common practice dealing with zero humidity or, at best, an assumed humidity. Humidity plays an important role in the oxygen gas transmission rate (O 2 GTR) of many materials. This test method provides for the determination of oxygen gas transmission rate (O 2 GTR), the permeance of the film to oxygen gas (P'O 2 ), and oxygen permeability coefficient (P''O 2 ) in the case of homogeneous materials at given temperature and %RH levels(s).
1.2 The values stated in SI units are to be regarded as the standard.
1.3 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. Specific precautionary statements are given in Section 9.
