21、ners secured together so as to be handled as an entity.4. Significance and Use4.1 These test methods will allow the user to determineintegrity and stability of the load as well as provide guidanceto improve the design of the shipping container or the unit loadwhere deficiencies are found.4.2 Damage
22、to products or packages observed during testingcan be expected to correlate at least in a qualitative way todamage observed in actual distribution handling systems.4.3 The results received from shock machine testing andfree fall drop testing are different for certain products. Wherethis test is perf
23、ormed to satisfy a regulatory or contractualrequirement, its use is subject to approval by the agencyconcerned.5. Apparatus5.1 Drop Test ApparatusIn performing the drop test, thecase, crate, or unitized load may be handled with any conve-nient equipment, such as a block and tackle, a hoist, or jacks
24、with provision made for releasing the test item either by pullingsupporting blocks from under it when tackle and jacks are usedor by a release hook when a hoist is used.5.1.1 Other apparatus may be used for dropping a case,crate, or unitized load as follows:5.1.1.1 Lift with heavy steel strapping or
25、 wire (to release,the strapping or wire is cut), or5.1.1.2 Lift with a forklift truck (while restraining the testitem, the forklift truck is removed from under it), or5.1.1.3 Lift with a clamp truck. (Apply sufficient force to lifttest item to prescribed height, then release test item), or5.1.1.4 Us
26、e a tractor with block and tackle (blocks arepulled from under test item) or,5.1.1.5 Use a commercial drop tester for test items that arewithin the weight limitations of the machine.5.1.2 Perform the test upon a flat, horizontally level, con-crete slab, pavement, or similarly unyielding surface, mas
27、siveenough to be immovable and rigid enough to be non-deformable under test conditions, with a mass at least 50 timesthat of the test item and large enough to ensure that the testpackage falls entirely upon the surface.5.2 Tip Test and Tipover Test Apparatus In performing thetip or tipover test, the
28、 test item may be handled with anyconvenient equipment, such as a forklift truck, a host, a blockand tackle, by hand, or any means capable of applying ahorizontal load to the vertical faces of the test item at aparticular height above the center of gravity and of sufficientforce to cause tipping wit
29、hout causing the test item to slide onthe horizontal surface. Perform the test upon a flat, horizontallylevel, concrete slab, pavement, or similarly unyielding surface,massive enough to be immovable and rigid enough to benon-deformable under test conditions, with a mass at least 50times that of the
30、test item and large enough to ensure that thetest item falls entirely upon the surface.5.3 Rolling Test ApparatusIn performing the rolling test,the test item may be handled with any convenient equipment,such as a forklift truck, a hoist, a block and tackle, or by hand.Perform the test upon a flat, h
31、orizontally level, concrete slab,pavement, or similarly unyielding surface, massive enough tobe immovable and rigid enough to be non-deformable undertest conditions, with a mass at least 50 times that of the testitem and large enough to ensure that the test item falls entirelyupon the surface.6. Tes
32、t Specimen and Number of Tests6.1 Test several cases, crates, or unitized loads of a givendesign, if possible, to obtain replication of results. If it is notpossible to test an entire unitized load, then sufficient articles orcontainers should be assembled such that the height and onebase dimension
33、are nearly the same as the proposed unitizedload. The same test item may often be used for all applicabletests if not tested to failure. Load the test item with the actualcontents for which it was designed. If use of actual contents isnot practical, a dummy load of the same total mass, size, andweig
34、ht distribution may be substituted. The contents or dummyload shall be blocked, braced, and cushioned in place and thepackage closed normally as for shipment.6.2 Identify faces, edges, and corners of containers asshown in Fig. A1.1 of Test Method D5276.3Available from American National Standards Ins
35、titute (ANSI), 25 W. 43rd St.,4th Floor, New York, NY 10036, http:/www.ansi.org.D6179 07 (2014)27. Conditioning7.1 It is recommended that atmospheres for conditioning beselected from those shown in Practice D4332. Unless other-wise specified, fiberboard and other paperboard containersshall be precon
36、ditioned and conditioned in accordance with thestandard atmosphere specified in Practice D4332.8. Acceptance Criteria8.1 Reference Practice D4169 for acceptance criteria andthe correlation to relative performance criteria.9. Drop Tests9.1 Test Method ARotational Edge Drop TestRaise oneend of the cas
37、e or crate and set it upon a timber or othersupport, placed at right angles to the length of the case or crate.The height of the support shall be sufficient to ensure that therewill be no support for the base between the ends of the test itemwhen dropping takes place, but should not be high enough t
38、ocause the test item to slide on the support when the drop end israised for the drop. Raise the other end of the test itemsuccessively to prescribed heights and release to fall freely onthe impact surface. Where test items are tall or top heavy,provision must be made to prevent the test item from ti
39、ppingover after the drop is made. The drop test impact surface isspecified fully in the Apparatus section. If the stability of theload is in question, the Tip Test (Test Method F) or the TipoverTest (Test Method G), or both, should be performed. SeeAnnex A1 for alternative drop test procedures.9.2 T
40、est Method BRotational Corner Drop TestStart upby setting up the case or crate as defined for the Test MethodA rotational edge drop test. Placea4to10in.(100 to 254 mm)block flat under one corner of the end already supported inorder to raise one corner higher than the other so that impactson the diag
41、onally opposite corner can be obtained. Raise theunsupported end of the test item so that the lower corner of thatend reaches a specified height from the impact surface andallow to fall freely. Where test items are tall or top heavy,provision must be made to prevent the test item from tippingover af
42、ter the drop is made. If the stability of the load is inquestion, the Tip Test (Test Method F) or the Tipover Test (TestMethod G), or both, should be performed. See Annex A1 foralternative drop test procedures.9.3 Test Method CRotational Flat Drop TestWith oneedge of the case, crate or unitized load
43、 supported by the floor,raise the other end to prescribed heights and release to fall flaton the impact surface. Where test items are tall or top heavy,provision must be made to prevent the test item from tippingover after the drop is made. If the stability of the load is inquestion, the Tip Test (T
44、est Method F) or the Tipover Test (TestMethod G), or both, should be performed. See Annex A1 foralternative drop test procedures.9.4 Test Method DUnsupported Free Fall Drop TestRaise the case, crate or unitized load above the impact surface,using apparatus as described in 5.1. Position load while in
45、 theair for flat bottom drop, edge, or corner drop as is desired.Release the test item and allow to fall freely. The angle of dropis at the users option but must be recorded. Where test itemsare tall or top heavy, provision must be made to prevent the testitem from tipping over after the drop is mad
46、e. If the stability ofthe load is in question, the Tip Test (Test Method F) or theTipover Test (Test Method G), or both, should be performed.See Annex A1 for alternative drop test procedures.NOTE 3When conducting a drop test using slings on a corrugatedfiberboard case, it is necessary to install a n
47、ominal 2 by 6 in. (50 by 150mm) wooden board at least 1 in. (25 mm) longer than the dimension of thecase on top of the case and in line with each sling. This board will preventeach sling from collapsing the top of the corrugated fiberboard case whenit is being lifted prior to the drop test.9.4.1 Tes
48、t Method EShock Machine MethodThe free falldrop test may, in some instances, be performed using aprogrammable shock machine of appropriate dimensions usingthe apparatus and procedures described in Test Method D5487.See 4.3 for an equivalency statement for the shock machinemethod and free fall method
49、 of drop testing. See Annex A1 foralternative drop test procedures.9.5 Measurements During Drop Tests (Optional)Measuredimensions of the test item, typically diagonals, and recordbefore the test is started and after each drop. The differences insuccessive measurements permit a study of the distortions anddeflections that have taken place. In addition to these measures,a record should be made of any changes or breakage in the testitem and their location.
