        • Designation: D 4169 – 08

          Standard Practice for

          Performance Testing of Shipping Containers and Systems

          1

          This standard is issued under the fifixed designation D 4169; the number immediately following the designation indicates the year of

          original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A

          superscript epsilon (´) indicates an editorial change since the last revision or reapproval.

          This standard has been approved for use by agencies of the Department of Defense.

          1. Scope

          1.1 This practice provides a uniform basis of evaluating, in

          a laboratory, the ability of shipping units to withstand the

          distribution environment. This is accomplished by subjecting

          them to a test plan consisting of a sequence of anticipated

          hazard elements encountered in various distribution cycles.

          This practice is not intended to supplant material specififications

          or existing preshipment test procedures.

          1.2 This practice does not include performance testing of

          packages for single parcel shipments (see Practice D 7386).

          1.3 The suitability of this practice for use with hazardous

          materials has not been determined.

          1.4 The values stated in inch-pound units are to be regarded

          as standard. The values given in parentheses are mathematical

          conversions to SI units that are provided for information only

          and are not considered standard.

          1.5 This standard does not purport to address all of the

          safety concerns, if any, associated with its use. It is the

          responsibility of the user of this standard to establish appro

          priate safety and health practices and determine the applica

          bility of regulatory limitations prior to use.

          3.2 Defifinitions of Terms Specifific to This Standard:

          3.2.1 acceptance criteria—the acceptable quality level that

          must be met after the shipping unit has been subjected to the

          test plan. See Section 7.

          3.2.2 assurance level—the level of test intensity based on

          its probability of occurring in a typical distribution cycle.

          3.2.2.1 Discussion—Level I is a high level of test intensity

          and has a low probability of occurrence. Level III is a low level

          of test intensity, but has a correspondingly high probability of

          occurrence. Level II is between these extremes. For Distribu

          tion Cycle 18 (DC–18), see MIL-STD-2073–1 for defifinitions

          of military levels of protection.

          3.2.3 coeff?cient of restitution—the ratio of the rebound

          velocity to the impact velocity.

          3.2.4 distribution cycle (DC)—the sequential listing of the

          test schedules employed to simulate the hazard elements

          expected to occur for a specifific routing of a shipping unit from

          production to consumption. See Table 1.

          3.2.5 feeder aircraft—small, potentially non-pressurized

          aircraft used to transport express packages.

          3.2.6 hazard element—a specifific event that occurs in a

          distribution cycle that may pose a hazard to a shipping unit.

          The element will usually be simulated by a single test schedule.

          See Section 9.

          3.2.7 shipping unit—the smallest complete unit that will be

          subjected to the distribution environment, for example, a

          shipping container and its contents.

          3.2.7.1 small shipping unit—for DC-18, a small shipping

          unit is defifined as one having no edge dimension or diameter

          over 60 in. (1.52 m) and a gross weight of 100 lb (45 kg) or

          less.

          3.2.7.2 large shipping unit—for DC-18, a large shipping

          unit is defifined as one having at least one edge dimension or

          diameter over 60 in. (1.52 m) or a gross weight in excess of 100

          lb (45 kg), or it is one that has a gross weight exceeding 100 lb

          (45 kg) and is secured to a base or to the base of a shipping

          unit.

          3.2.8 test plan—a specifific listing of the test sequence to be

          followed to simulate the hazards anticipated during the distri

          bution cycle of a shipping unit. Included will be the test

          intensity and number of sequential tests to be conducted. See

          8.5.

          3.2.9 test schedule—the specifific procedure to be used,

          including the three assurance level intensities, and a reference

          to the test method that is the basis of the schedule.

          3.2.9.1 Discussion—The purpose of the schedule is to

          simulate the forces occurring during any hazard element of the

          distribution cycle. See Section 9.

          3.2.10 total velocity change, (DV)—the sum of the impact

          and rebound velocities.

          3.3 Abbreviations:

          3.3.1 TOFC—trailer on flflatcar.

          3.3.2 COFC—container on flflatcar.

          3.3.3 TL—truckload.

          3.3.4 CL—carload.

          3.3.5 LTL—less than truckload.

          4. Signifificance and Use

          4.1 This practice provides a guide for the evaluation of

          shipping units in accordance with a uniform system, using

          established test methods at levels representative of those

          occurring in actual distribution. The recommended test levels

          are based on available information on the shipping and

          handling environment, and current industry/government prac

          tice and experience (1-13).

          5

          The tests should be performed

          sequentially on the same containers in the order given. For use

          as a performance test, this practice requires that the shipping

          unit tested remain unopened until the sequence of tests are

          completed. If used for other purposes, such as package

          development, it may be useful to open and inspect shipping

          units at various times throughout the sequence. This may,

          however, prohibit evaluating the inflfluence of the container

          closure on container performance.

          4.2 For Distribution Cycle 18, as referred to in MIL-STD-

          2073–1, the use of this practice is defifined in subsequent

          sections identifified as DC-18.

          5. Test Specimen

          5.1 Test specimens consist of representative samples of

          complete shipping units, including actual contents. Products

          with blemishes or minor defects may be used if the defective

          component is not to be studied by the test and if the defect is

          documented in the report. Dummy test loads are acceptable if

          testing the actual product might be hazardous. If a dummy load

          is used, it should be instrumented to determine if the fragility

          level of the actual product has been exceeded. Take care to

          duplicate the load characteristics of the actual product, and

          avoid unnecessary prehandling.

          5.2 Care must be taken to ensure that no degradation has

          occurred to either the product or the package if the test

          packages have been shipped to the test site. If any doubt exists

          as to the condition of the package, repack the product in new

          packaging material before testing.

          5.3 The number of test replications depends on the desired

          objectives of the testing and the availability of duplicate

          products and shipping containers. Replicate testing is recom

          mended to improve the reliability of the test results.

          6. Conditioning

          6.1 If the distribution cycle contains climatic conditions that

          have an effect on the performance characteristics of the

          product, shipping container, or components such as cushioning,

          use one of the following procedures. (It should be noted that

          different atmospheric conditions are likely to exist between the

          origin 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 the

          shipping units to a standard atmosphere of 73.4 6 2°F (23 6

          1°C) and 50 6 2 % relative humidity. Condition fifiberboard

          containers in accordance with Practice D 4332. The same

          atmospheric condition should be used for any assurance level.
