16、 level of test intensity based onits probability of occurring in a typical distribution cycle.3.2.2.1 DiscussionLevel I is a high level of test intensityand has a low probability of occurrence. Level III is a low levelof test intensity, but has a correspondingly high probability ofoccurrence. Level

17、II is between these extremes.

(1.52 m) or

See8.5.3.2.9 test schedulethe specific procedure to be used,including the three assurance level intensities, and a referenceto the test method that is the basis of the schedule.3.2.9.1 DiscussionThe

23、 purpose of the schedule is tosimulate the forces occurring during any hazard element of thedistribution cycle.

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 recommended test levels

25、are based on available information on the shipping andhandling environment, and current industry/government prac-tice and experience (1-13).5The tests should be performedsequentially on the same containers in the order given. For useas a performance test, this practice requires that the shippingunit

26、 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 containerclosure on contai

27、ner performance.4.2 For Distribution Cycle 18, as referred to in MIL-STD-20731, 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. Productswith blemis

28、hes 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 determine if the fragilityle

29、vel 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 shipped to the test

30、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. Replicate testing is recom-me

31、nded 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 procedures. (It should be n

32、oted 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. Condition theshipping units

33、 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 condition should be used for any assurance level.A conditioning period of 72 h, or sufficient time to reachequilibrium of all parts of

34、 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 from the conditioning atmosphere as5The boldface numbers in parentheses refer to a list of references at the end ofthis practi

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 choo

49、se 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-tainers whose shipping history is known.7.2 In many cases, the acceptance criteria can be thefollowing:Criterion 1Product is damage-free.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
