Standard Test Method for Leakage Testing of Empty Rigid Containers by Vacuum Method 用真空法对空的刚性容器进行泄漏试验的标准试验方法
发布日期: 2023-03-15
1.1 本试验方法包括在压差条件下对空容器进行抗泄漏试验,例如在空运过程中可能发生的情况。它适用于根据《联合国危险货物运输建议》(UN TDG)和国际民用航空组织《危险货物安全空运技术说明》(ICAO TI)测试用于运输某些危险液体的刚性容器。 1.2 本标准并非旨在解决与其使用相关的所有安全问题(如有)。 本标准的使用者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。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 容器可根据本试验方法加压,而无需对容器的封闭件或主体进行修改。 本试验方法可用于根据ICAO TI或联合国TDG对用于空运某些液体的刚性容器进行试验。 5.2 该测试方法确定了泄漏开始的点,极限约为95 千帕(13.8 psi)压差。参见测试方法 第3078页 用于柔性封装。 5.3 这种测试方法可能不适用于某些包装,例如带有纸帽密封的包装,因为在这些包装中,测试液可能会迅速损坏包装。
1.1 This test method covers the testing of empty containers for resistance to leakage under differential pressure conditions such as those which can occur during air transport. It is suitable for testing rigid containers intended for the transportation of some hazardous liquids in accordance with the United Nations Recommendations On The Transport Of Dangerous Goods (UN TDG) and the International Civil Aviation Organization Technical Instructions For The Safe Transport Of Dangerous Goods By Air (ICAO TIs). 1.2 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. 1.3 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 Containers may be pressurized in accordance with this test method without modification to the closure or to the body of the container. This test method may be used for testing rigid containers intended for the transportation of some liquids by air in accordance with the ICAO TIs or in accordance with the UN TDG. 5.2 This test method establishes the point at which leakage commences, with a limit of approximately 95 kPa (13.8 psi) differential. See Test Method D3078 for flexible packages. 5.3 This test method may not be suitable for some packages, such as packages with paper cap seals, where the test fluid may rapidly deteriorate the packaging.
