See Section 7.3.2.2 assurance levelthe level of test intensity based onits probability of occurring in

16、 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 II is between these extremes. For Distribu-tion Cycle 18 (DC18),

(1.52 m) and a gross weight of 100 lb (45 kg) orless.3.2.7.2 large shipping unitfor DC-18, a large shippingunit is defined as one having at least one edge dimension ordiameter over 60 in. (1.52 m) or a gross weight in excess of 100lb (45 kg), or it is one that ha

21、s a gross weight exceeding 100 lb(45 kg) and is secured to a base or to the base of a shippingunit.3.2.8 test plana specific listing of the test sequence to befollowed to simulate the hazards anticipated during the distri-bution cycle of a shipping unit. Included will be the testintensity and number

22、 of sequential tests to be conducted. 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 purpose of the schedule is tosimulate the forces occurring duri

Significance and

24、 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 levelsare based on available information on the shipping andhandling e

25、nvironment, 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 tested remain unopened until the sequence of tests arecompleted

26、. 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 container performance.4.2 For Distribution Cycle 18, as referred to in

27、 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 blemishes or minor defects may be used if the defectivecomponent is no

28、t 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 fragilitylevel of the actual product has been exceeded. Take care toduplica

29、te 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 site. If any doubt existsas to the condition of the package, rep

30、ack 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-mended to improve the reliability of the test results.6. Condition

31、ing6.1 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 noted thatdifferent atmospheric conditions are likely to exist be

32、tween 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 to a standard atmosphere of 73.4 6 2F (23 61C) and 50 6 2 % rel

33、ative humidity. Condition fiberboardcontainers in accordance with Practice D 4332. The sameatmospheric condition should be used for any assurance level.5The boldface numbers in parentheses refer to a list of references at the end ofthis practice.D4169082TABLE 1 Distribution CyclesPerformance Test Sc

44、4169083A 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 from the conditioning atmosphere a

45、spracticable. 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 D 4332, or Test Method D 951,orothers (salt, spr

46、ay, water immersion, humidity, or temperature).The same climatic condition should be used for any assurancelevel. A conditioning period should be provided which willallow sufficient time to reach equilibrium of all parts of thepackage and product. Tests should be conducted in the condi-tioned atmosp

47、here whenever possible. If not possible, conductthe tests as soon after removal from the conditioning atmo-sphere as practicable. Recondition the shipping units as nec-essary during the test plan. For atmospheres other than thestandard conditioning atmosphere, the user must determine theappropriate

48、compressive load factor for warehouse and vehiclestacking, as the factors given in 11.2 are based on testing underthe standard test atmosphere.7. Acceptance Criteria7.1 Acceptance criteria must be established prior to testingand should consider the required condition of the product atreceipt. The or

49、ganizations 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-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 contentsar
