When transported overland at altitude or by air, products are subject to fairly significant pressure differentials, which can lead to the risk of leaks or product deformation.

ASTM D6653-19 describes standard test methods for determining the effects of high altitude on vacuum packaging systems. This standard provides detailed instructions for testing packaged products under vacuum conditions simulating the high altitudes encountered during high-altitude air or land transport. Designed to assess the ability of packaging systems to withstand pressure changes and protect packaged products from damage. This test is capable of simulating conditions at an altitude of 11,000 meters.

The standard describes the requirements for test equipment, including vacuum gauges, inlet and outlet tubes, and manual valves. It also specifies the minimum size of the test chamber to allow expansion of packaged products. The test specimens and number of samples required are also defined to enable adequate determination of representative performance.

ASTM D6653-19 also includes detailed instructions for preparing samples, carrying out tests and interpreting results. Test results must be recorded and included in a report that complies with the requirements of the standard.

It is important to note that this standard does not address all the safety concerns associated with its use. It is the responsibility of the user of the standard to implement appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use of this standard.

In summary, ASTM D6653-19 provides detailed instructions for testing the effects of high altitude on vacuum packaging systems. This standard is useful for manufacturers and carriers of packaged products who need to ensure that their products are protected against damage caused by pressure changes during transport.
