(991 by 686 mm), used to containand transport several small sized packages and envelopes.4. Significance and Use4.1 This practice provides a guide for the evalu
18、ation of shipping units in accordance with a uniform system, using establishedtest methods at levels representative of those occurring in actual distribution. The recommended test levels are based on availableinformation on the shipping and handling environment, and current industry/government pract
19、ice and experience. The tests shouldbe performed sequentially on the same containers in the order given. For use as a performance test, this practice requires that theshipping unit tested remain unopened until the sequence of tests are completed. If used for other purposes, such as packagedevelopmen
20、t, it may be useful to open and inspect shipping units at various times throughout the sequence. This may, however,prohibit evaluating the influence of the container closure on container performance.5. Test Specimen5.1 Test specimens consist of representative samples of complete shipping units, incl
21、uding actual contents. Products withblemishes or minor defects may be used if the defective component is not to be studied by the test and if the defect is documentedin the report. Dummy or simulated test loads are acceptable if testing the actual product might be hazardous. If a dummy load isused,
22、it should be instrumented to determine if the fragility level of the actual product has been exceeded. Take care to duplicatethe load characteristics of the actual product, and to avoid unnecessary handling.5.2 Care must be taken to ensure that no degradation has occurred to either the product or th
23、e package if the test packages havebeen shipped to the test site. If any doubt exists as to the condition of the package, repack the product in new packaging materialbefore testing.5.3 The number of test replications depends on the desired objectives of the testing and the availability of duplicate
24、productsand shipping containers. Replicate testing is recommended to improve the reliability of the test results.5.4 Identification of Package Test Specimen Members:5.4.1 Small Containers Bagged for Transport by Carrier, Sacks and BagsSmall packaged products (smaller than800 in.3 (13 110 cc) and les

36、 Face 6.6. Conditioning6.1 Conduct the test at standard conditions and compensate for the effects of any climatic condition. Condition containers inaccordance with Practice D4332 and document the actual conditions used.Aconditioning period of 72 h, or sufficient time to reachequilibrium of all parts
37、 of the package and product is recommended. Tests should be conducted in the conditioned atmospherewhenever possible. If not possible, conduct the tests as soon after removal from the conditioning atmosphere as practicable.Recondition the shipping units to the standard atmosphere as necessary during
38、 the test plan.6.2 In some circumstances, it may be necessary to conduct some or all of the tests at special climatic conditions, such as thosegiven in Practice D4332, or Test Method D951, or others (salt, spray, water immersion, humidity, or temperature). The sameclimatic condition should be used f
39、or any assurance level. A conditioning period of 24 h, or sufficient time to reach equilibriumof all parts of the package and product is recommended. Tests should be conducted in the conditioned atmosphere wheneverpossible. If not possible, conduct the tests as soon after removal from the conditioni
40、ng atmosphere as practicable. Recondition theshipping units as necessary during the test plan.7. Acceptance Criteria7.1 Acceptance criteria must be established prior to testing and should consider the required condition of the product at receipt.The organizations conducting the test may choose any a
41、cceptance criteria suitable for their purpose. It is advisable to compare theFIG. 2 Members of Rectangular ContainersD7386 163type and quantity of damage that occurred to the test specimens with the damage that occurs during actual distribution and handlingor with test results of similar containers
42、whose shipping history is known.7.2 In many cases, the acceptance criteria can be the following:Criterion 1Product is damage-free.Criterion 2Package is intact.Criterion 3Both criteria 1 and 2.7.2.1 Often, this means that the shipping container and its contents are suitable for normal sale and use at
43、 the completion of thetest cycle. Detailed acceptance criteria may allow for accepting specified damage to a product or its package. The form and contentof acceptance criteria may vary widely, in accordance with the particular situation. Methods may range from simple pass-failjudgments to highly qua
