1.1 本试验方法包括检测包装中的严重泄漏。方法灵敏度降至250μm（0.010 in.）有一个81 % 概率（参见第节 11 ). 本试验方法可用于托盘和邮袋包装。 1.2 本试验方法的灵敏度尚未评估用于纺粘聚烯烃以外的多孔材料或无孔包装。 1.3 该测试方法具有破坏性，因为它需要进入包装以提供内部气压 1.4 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.5 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。 1.6 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 内部加压试验方法提供了一种检查包装是否存在严重泄漏的实用方法。 5.2 该测试方法在没有常见包装材料/尺寸的测试实验室环境中非常有用。 5.3 本试验方法可适用于不适合任何其他包装完整性试验方法装置的大型或长包装。 5.4 该测试方法可作为评估包装完整性的手段。包装完整性对消费者安全至关重要，因为热封包装的设计目的是为产品提供无污染或无菌环境，或两者兼而有之。 5.5 该测试方法可用于检测基板孔和通道。

1.1 This test method covers the detection of gross leaks in packaging. Method sensitivity is down to 250 μm (0.010 in.) with an 81 % probability (see Section 11 ). This test method may be used for tray and pouch packages. 1.2 The sensitivity of this test method has not been evaluated for use with porous materials other than spunbonded polyolefin or with nonporous packaging. 1.3 This test method is destructive in that it requires entry into the package to supply an internal air pressure 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. 1.6 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 The internal pressurization test method provides a practical way to examine packages for gross leaks. 5.2 This test method is extremely useful in a test laboratory environment where no common package material/size exists. 5.3 This test method may apply to large or long packages that do not fit into any other package integrity test method apparatus. 5.4 This test method may be used as a means to evaluate package integrity. Package integrity is crucial to consumer safety since heat sealed packages are designed to provide a contamination free or sterile environment, or both, to the product. 5.5 This test method may be used to detect substrate holes and channels.
