ASTM E2609-08

1.1 This test method covers a recommended procedure for examining odor or flavor properties or both of rigid polymeric packaging closures and fillable materials.

1.2 This test method can be used for single materials or coextruded materials that are foam molded, injection molded, blow molded, compression molded, or thermoformed polymers.

1.3 The focus of this test method is the evaluation of molded polymer in terms of the transfer of package-related odors, flavors, or both, to water and other model systems (bland food simulants). Rigid packaging forms vary considerably in type, size, and shape. Thus, customizing the exact procedure for dealing with the physical requirements for individual packages is the responsibility of the user.

1.4 This test method assumes testing of the materials at a one-time point; shelf-life testing is not included.

1.5 Refer to Test Method E 1870 for the evaluation of inherent odor of packaging material by confinement tests.

1.6 This test method provides sample preparation procedures and two methods of evaluation.

1.6.1 The package performance score method allows for the comparison of any molded polymer sample to another.

1.6.2 The ranking method allows for comparison of samples within the currently tested set only.

1.6.3 The preparation of samples is consistent regardless of the method of evaluation used.

1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.8 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.
