ASTM D6653 High Altitude on Packaging Systems by Vacuum Method

The scope of ASTM D6653 sustainability testing determines the effects of pressure differential when packaged products are transported via certain modes of transport, such as feeder aircraft or ground over high mountain passes. The results of these tests are intended to be used for qualitative purposes.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents. Therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

Packaged products transported via the feeder aircraft network are liable to experience altitudes as high as 19,000 feet. When exposed to these high-altitude conditions, products or packaging systems, or a combination thereof, may be affected negatively by the resultant pressure differential.

ASTM D6653 package testing is suitable for evaluating the effect of high altitude on packaging systems. ASTM D6653 testing is suitable for package or product, or both, development and engineering.

High Altitude ASTM D6653 Testing Procedures

Note that much of the following information below may be modified based on knowledge of shipping environment, product value, desired damage level acceptances, or other criteria.


If conditioning prior to testing or during the test is not possible, then it is recommended to condition the test specimen to a standard conditioning atmosphere of 23°C +/- 2°C for a minimum of 24 hours before to testing. The test specimens and the number of samples chosen must adequately represent performance for a portion of the samples produced.


A test specimen is placed in a vacuum chamber.  The chamber inlet valve is closed, and the outlet valve is opened. The outlet valve turns the vacuum source on so that the gauge rises at an approximate rate of 305(m) for 30-60(s) until the appropriate pressure is achieved. Maintain the vacuum for 60(min).

Certain pressure levels are attained for test specimens tested at condition specifications. As mentioned above, the vacuum pressure may be modified based on the knowledge of a certain environment.

Lastly, the chamber inlet is slowly opened and the specimen is removed from the vacuum chamber. The specimen is then examined for any damage or deformation.
