ASTM F2714-08(2013)

3.1 The oxygen content of a package’s headspace is an important determinant of the packaging protection afforded by barrier materials. The package under test is typically MAP (modified atmosphere packaging) packaged.

3.2 Oxygen content is a key contributor to off-flavors and spoilage of various products, such as chemicals, food and pharmaceuticals.

3.3 The method determines the oxygen in a closed package headspace. This ability has application in:

1.1 This test method covers a procedure for determination of the oxygen concentration in the headspace within a sealed package without opening or compromising the integrity of the package.

1.2 This test method requires that chemically coated components be placed on the inside surface of the package before closing.

1.3 The package must be either transparent, translucent, or a transparent window must be affixed to the package surface without affecting the package’s integrity.

1.4 As this test method determines the oxygen headspace over time, the oxygen permeability can easily be calculated as ingress per unit time as long as the volume of the container is known.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.
