Significance and Use4.1 This practice provides a guide for the evalu

25、ation ofshipping units in accordance with a uniform system, usingestablished test methods at levels representative of thoseoccurring in actual distribution. The recommended test levelsare based on available information on the shipping andhandling environment, and current industry/government prac-tic

26、e and experience (1-13).6The tests should be performedsequentially on the same containers in the order given. For useas a performance test, this practice requires that the shippingunit tested remain unopened until the sequence of tests arecompleted. If used for other purposes, such as packagedevelop

27、ment, it may be useful to open and inspect shippingunits at various times throughout the sequence. This may,however, prohibit evaluating the influence of the containerclosure on container performance.4.2 For Distribution Cycle 18, as referred to in MIL-STD-20731, the use of this practice is defined

28、in subsequentsections identified as DC-18.5. Test Specimen5.1 Test specimens consist of representative samples ofcomplete shipping units, including actual contents. Productswith blemishes or minor defects may be used if the defectivecomponent is not to be studied by the test and if the defect isdocu

29、mented 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 determine if the fragilitylevel of the actual product has been exceeded. Take care toduplicate the load characteristics of the actual product, a

30、ndavoid 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 shipped to the test site. If any doubt existsas to the condition of the package, repack the product in newpackaging material before test

31、ing.5.3 The number of test replications depends on the desiredobjectives of the testing and the availability of duplicateproducts and shipping containers. Replicate testing is recom-mended to improve the reliability of the test results.6. Conditioning6.1 If the distribution cycle contains climatic c

44、 Conduct the test at standard conditions and compen-sate for the effects of any climatic condition. Condition theshipping units to a standard atmosphere of 73.4 6 2F (23 61C) and 50 6 2 % relative humidity. Condition fiberboardcontainers in accordance with Practice D4332. The sameatmospheric conditi

45、on should be used for any assurance level.A conditioning period of 72 h, or sufficient time to reachequilibrium of all parts of the package and product is recom-mended. Tests should be conducted in the conditioned atmo-sphere whenever possible. If not possible, conduct the tests assoon after removal

46、 from the conditioning atmosphere aspracticable. Recondition the shipping units to the standardatmosphere as necessary during the test plan.6.1.2 In some circumstances, it may be necessary to conductsome or all of the tests at special climatic conditions, such asthose given in Practice D4332, or Tes

47、t Method D951, or others(salt, spray, water immersion, humidity, or temperature). Thesame climatic condition should be used for any assurance level.A conditioning period should be provided which will allowsufficient time to reach equilibrium of all parts of the packageand product. Tests should be co

48、nducted in the conditionedatmosphere whenever possible. If not possible, conduct thetests as soon after removal from the conditioning atmosphereas practicable. Recondition the shipping units as necessaryduring the test plan. For atmospheres other than the standardconditioning atmosphere, the user mu

Acceptance Criteria7.1 Acceptance criteria must be established prior to testingand should consider the required condition of the product atreceipt. 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 a
