Significance and Use
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.
This test method establishes the point at which leakage commences, with a limit of approximately 95-kPa (13.8-psi) differential. See Test Method D 3078
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.
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 and health practices and determine the applicability of regulatory limitations prior to use.
