Standard Practice for Conditioning and Testing Flexible Barrier Packaging
1.1 This practice defines the standard temperature and humidity for conditioning and testing of flexible barrier packaging and flexible barrier packaging materials at nominally ambient conditions.
1.2 There are many other temperature and humidity conditions that may be appropriately used to test end use conditions (such as freezer, refrigerated, or abusive storage). These need to be individually established and are not in the scope of this practice.
1.3 Only those materials that fall under the general area of flexible barrier packaging materials are included in this practice.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
