(Test Method)Standard Test Method for Oxygen Transmission Rate Through Dry Packages Using a Coulometric Sensor
Standard Test Method for Oxygen Transmission Rate Through Dry Packages Using a Coulometric Sensor
SIGNIFICANCE AND USE
5.1 Oxygen gas transmission rate is an important determinant of the protection afforded by barrier materials. It is not, however, the sole determinant, and additional tests, based on experience, must be used to correlate package performance with O2GTR. This test method is suitable as a referee method of testing, provided that the user and source have agreed on sampling procedures, standardization procedures, test conditions, and acceptance criteria.
SCOPE
1.1 This test method covers a procedure for the determination of the steady-state rate of transmission of oxygen gas into packages. More specifically, the method is applicable to packages that in normal use will enclose a dry environment.
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.

4. Summary of Test Method
4.1 This test method employs a coulometric oxygen sensor and associated equipment in an arrangement similar to that described
in Test Method D3985. Oxygen gas transmission rate (O GTR) is determined after the package has been mounted on a test fixture
2
and has equilibrated in the test environment.
4.2 The package is mounted in such a way as to provide that the inside of the package is slowly purged by a stream of nitrogen
while the outside of the package is exposed to a known concentration of oxygen.
