Significance and Use4.1 This practice provides a guide for the evaluation ofshipping units in accordance with a uniform system, usingestablished test methods at levels representative of thoseoccurring in actual distribution. The r
23、ecommended test levelsare based on available information on the shipping andhandling environment, and current industry/government prac-tice and experience (1-13).4The tests should be performedsequentially on the same containers in the order given. For useas a performance test, this practice requires
24、 that the shippingunit tested remain unopened until the sequence of tests arecompleted. If used for other purposes, such as packagedevelopment, it may be useful to open and inspect shippingunits at various times throughout the sequence. This may,however, prohibit evaluating the influence of the cont
25、ainerclosure on container performance.4.2 For Distribution Cycle 18, as referred to in MIL-STD20731, the use of this practice is defined in subsequentsections identified as DC-18.5. Test Specimen5.1 Test specimens consist of representative samples ofcomplete shipping units, including actual contents
26、. Productswith blemishes or minor defects may be used if the defectivecomponent is not to be studied by the test and if the defect isdocumented in the report. Dummy test loads are acceptable iftesting the actual product might be hazardous. If a dummy loadis used, it should be instrumented to determi
27、ne if the fragilitylevel of the actual product has been exceeded. Take care toduplicate the load characteristics of the actual product, andavoid unnecessary prehandling.5.2 Care must be taken to ensure that no degradation hasoccurred to either the product or the package if the testpackages have been
28、 shipped to the test site. If any doubt existsas to the condition of the package, repack the product in newpackaging material before testing.5.3 The number of test replications depends on the desiredobjectives of the testing and the availability of duplicateproducts and shipping containers. Replicat
29、e testing is recom-mended to improve the reliability of the test results.6. Conditioning6.1 If the distribution cycle contains climatic conditions thathave an effect on the performance characteristics of theproduct, shipping container, or components such as cushioning,use one of the following proced
30、ures. (It should be noted thatdifferent atmospheric conditions are likely to exist between theorigin and destination points of a distribution cycle, particu-larly for export/import cycles.):6.1.1 Conduct the test at standard conditions and compen-sate for the effects of any climatic condition.

Acceptance Criteria7.1 Acceptance criteria must be established prior to testingand should consider the required condition of the product atreceipt.
48、The organizations conducting the test may choose anyacceptance criteria suitable for their purpose. It is advisable tocompare the type and quantity of damage that occurred to thetest specimens with the damage that occurs during actualdistribution and handling or with test results of similar con-tain
49、ers whose shipping history is known.7.2 In many cases, the acceptance criteria can be thefollowing:Criterion 1Product is damagefree.Criterion 2Package is intact.Criterion 3Both criteria 1 and 2.Often, this means that the shipping container and its contentsare suitable for normal sale and use at the completion of the testcycle. Detailed acceptance criteria may allow for acceptingspecified damage to a product or its package. The form andcontent of acceptance criteria may vary widely, in accordancewith the particular situation. Methods may range from si
