A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was corrected editorially in March 2011.1. Scope1.1 These test

3、 methods determine the effects of pressuredifferential when packaged products are transported via certainmodes of transport, such as feeder aircraft or ground over highmountain passes. The results of these tests are intended to beused for qualitative purposes.1.2 The values stated in either SI units

4、 or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not

Sampling6.1 The test specimens and number of samples shall bechosen to permit an adequate determination of representativeperformance (see Practice E122).6.2 In the absence of any sampling plan, at least th

18、reerepresentative specimens should be selected for performanceevaluation.7. Test Specimen7.1 Atest specimen shall consist of an assembled packagingsystem, representative of a production run package, or compo-nents of an assembled packaging system, to include primaryand/or secondary packaging.8. Cond

19、itioning8.1 Test specimens shall be conditioned to 5.6 6 2C 42 63.6F for a minimum of 24 h prior to testing.8.2 Test specimens shall be tested in and at conditions of 5.66 2C 42 6 3.6F.48.3 If conditioning prior to testing or during test is notpossible, then it recommended to condition test specimen

20、 to astandard conditioning atmosphere of 23 6 2C 73.4 6 3.6Ffor a minimum of 24 h prior to testing (see Practice D4332)8.4 Conditioning specifications may be modified based onknowledge of shipping environment, product value, desireddamage level acceptances, or other criteria (see Appendix X1for guid

21、ance).9. Procedure9.1 Place the test specimen in the vacuum chamber. Closethe chamber inlet valve, open the outlet valve and turn thevacuum source on so that the gauge rises at an approximate rateof 305 m 1 000 ft 30-60 s until the appropriate pressure isachieved.9.1.1 Attain a pressure equivalent t

23、owledge of shipping environment, product value, desireddamage level acceptances, or other criteria (see Appendix X1and Table X2.1 for guidance).9.2 Maintain the vacuum for 60 min. The test duration maybe modified based on knowledge of shipping environment,product value, desired damage level acceptan

24、ces, or othercriteria (see Appendix X1 and Table X2.1 for guidance).9.3 Partially open the chamber inlet valve and release thevacuum at a rate of approximately 305 m 1 000 ft per 30-60s.9.4 Open the chambers cover and remove the test specimenand examine for any damage or deformation.59.5 Record the

25、results of examination.10. Interpretation of Results10.1 If a distribution packaging system was tested and theclosure, shipping container, internal packaging and product areintact and free of damage, then the packaging system should bereassembled for testing in accordance with an industry ac-cepted

26、packaged-product performance test, such as PracticeD4169. This will help determine if the pressure differential hadan affect on the performance of the packaging system. It isrecommended to test a new test specimen with the samepackaged-product performance test without the altitude condi-tioning for

27、comparative purposes.11.
