3、pe1.1 These test methods determine the effects of pressure differential when packaged products are transported via certain modesof transport, such as feeder aircraft or ground over high mountain passes. The results of these tests are intended to be used forqualitative purposes.1.2 The values stated
4、in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 Th

United States14. Significance and Use4.1 Packaged products transported via the feeder aircr
14、aft network are liable to experience altitudes as high as 5 791 m 19 000ft.4 When exposed to these high altitude conditions, products or packaging systems, or a combination thereof, may be affectednegatively by the resultant pressure differential.4.2 These test methods are suitable for evaluating th
15、e effect of high altitude on packaging systems.4.3 These test methods are suitable for package or product, or both, development and engineering.4.4 Other test methods, such as Test Methods D3078, D4991 and D5094, test for leakage of packaging systems by vacuummethod and are applicable for testing th
16、e effects of high altitude.5. Apparatus5.1 Vacuum ChamberAny suitable chamber capable of withstanding approximately one atmosphere pressure differential fittedwith a flat-vacuum-tight cover or equivalent chamber providing the same functional capabilities, such as an altitude chamber.5.2 Vacuum Gage,
17、 Inlet Tube from a Source of Vacuum and Outlet Tube to the Atmosphere, shall be sealed to the chamber. Theinlet and outlet tubes shall be equipped with hand operated valves. The vacuum gauge shall be laboratory quality with a full-scalerange of 0 to 100 kPa 0 to 30 in. Hg with minimum graduation no
18、greater than 2 kPa 1 in. Hg and accuracy to within 2 %.5.3 The Chamber, shall be large enough to contain the test specimen, as well as allow for the expansion of the product orpackage, or both.6. Sampling6.1 The test specimens and number of samples shall be chosen to permit an adequate determination
19、 of representativeperformance (see Practice E122).6.2 In the absence of any sampling plan, at least three representative specimens should be selected for performance evaluation.7. Test Specimen7.1 Atest specimen shall consist of an assembled packaging system, representative of a production run packa
20、ge, or componentsof an assembled packaging system, to include primary and/or secondary packaging.8. Conditioning8.1 Test specimens shall be conditioned to 5.6 6 2C 42 6 3.6F for a minimum of 24 h prior to testing.8.2 Test specimens shall be tested in and at conditions of 5.6 6 2C 42 6 3.6F.48.3 If c
21、onditioning prior to testing or during test is not possible, then it recommended to condition test specimen to a standardconditioning atmosphere of 23 6 2C 73.4 6 3.6F for a minimum of 24 h prior to testing (see Practice D4332)8.4 Conditioning specifications may be modified based on knowledge of shi
22、pping environment, product value, desired damagelevel acceptances, or other criteria (see Appendix X1 for guidance).9. Procedure9.1 Place the test specimen in the vacuum chamber. Close the chamber inlet valve, open the outlet valve and turn the vacuumsource on so that the gauge rises at an approxima

The
25、 test duration may be modified based on knowledge of shipping environment, productvalue, desired damage level acceptances, or other criteria (see Appendix X1 and Table X2.1 for guidance).9.3 Partially open the chamber inlet valve and release the vacuum at a rate of approximately 305 m 1 000 ft per 3

Interpretation of Results10.1 If a distribution packaging system was tested and the closure, shipping container, internal packaging and product are intactand free of damage, then the packaging system should be
29、reassembled for testing in accordance with an industry acceptedpackaged-product performance test, such as Practice D4169. This will help determine if the pressure differential had an affect onthe performance of the packaging system. It is recommended to test a new test specimen with the same package
