1.1 本试验方法涵盖了测定氧气进入包装的稳态传输速率的程序。更具体地说，该方法适用于正常使用时将封闭在干燥环境中的包装。 1.2 以国际单位制表示的数值应视为标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 氧气传输速率是屏障材料提供保护的重要决定因素。然而，这不是唯一的决定因素，必须使用基于经验的额外测试来将封装性能与O 2. 全球技术法规。如果用户和来源已就取样程序、标准化程序、测试条件和验收标准达成一致，则本测试方法适合作为测试的参考方法。

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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. ====== 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 O 2 GTR. 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.
