ASTM D6653 Test

Standard Test Methods for Determining the Effects of High Altitude on Packaging Systems by ASTM D6653 Vacuum Method

The purpose of ASTM D6653 ^ is to simulate the effects of the pressure difference on packaged products transported with different high altitude modes. Common examples of high-altitude transport are feeder aircraft and land transport at high mountain passes.

ASTM D6653 Test

A feeder plane is a small plane used to transport the express air package; in some cases, no pressure is applied to the aircraft. Packages carried by this method may experience high altitudes that negatively affect the package or its contents due to the pressure difference.

The test can be used to evaluate the effects of high altitude on packaging and also to identify areas of design and engineering that need to be improved to better withstand high altitudes.

The apparatus required for ASTM D6653 is a vacuum chamber. The vacuum chamber is suitable if it can withstand an atmospheric pressure difference equipped with a flat vacuum sealed cover. Height room is also acceptable. It should be a vacuum gauge, inlet pipe from a vacuum source and an outlet pipe to the atmosphere connected to the chamber. There must be hand operated valves in the inlet and outlet pipes. The vacuum indicator should be accurate within 2%, be of laboratory quality, be in the range of 0-100 kPa, and the minimum graduation should not be more than 2 kPa. The chamber should be large enough to contain the test sample, including any expansion that may occur during the test.

ASTM D6653 The test sample for will be the assembled packaging system. The system should represent actual packaging systems, including primary and secondary packaging. The test sample must be conditioned before testing. The conditioning criteria are as follows: The test sample must be conditioned to 24 +/- 5.6 ° C for at least 2 hours before testing. Test samples are tested in a conditioned environment. However, these conditions can be varied, but not limited to, the actual shipping environment, product value, and desired damage level.

Testing can begin after the package is conditioned. The test sample should be placed in the vacuum chamber. The valves should be adjusted so that the inlet valve is closed and the outlet valve is opened. The vacuum source should then be adjusted so that the gauge rises approximately 305 m 30-60 s until the desired pressure is reached. Once the desired vacuum is reached, it should be kept for 60 minutes (1 hour). Again, this can be varied, but not limited to, the actual shipping medium, product value, and desired damage level.

To release pressure, open the inlet valve to release the vacuum in which the vacuum was created. Once the vacuum has been released, open the hopper and inspect the packaging and contents for damage. The test lab records the test method and provides a report following ASTM D6653 guidelines.

If the pack is not damaged at the end of the altitude test, it is recommended to reassemble the pack to pass other tests. The follow-up test will help determine if the pressure difference has any effect on the packaging that was not visible at first.
