Th

17、isterminology may have to be agreed upon between supplier anduser.Fig. 14.4.2 Since all end use conditions and requirements cannotbe foreseen and since designing for worst case scenario for allapplications is prohibitively expensive, designers should fol-low best practices. The prudent designer will

18、 consider productand package weight when deciding the proper use of a handhole.5. General Design Considerations5.1 Hand holes can take many forms (see Fig. 1). They can:5.1.1 Be a simple hole in a box,5.1.2 Be a complex molded handle with a reinforcementmounted at the attaching point,5.1.3 Incorpora

19、te rope handles, and5.1.4 Be reinforced by the box maker with reinforcing tapeapplied above them.5.2 If possible, position hand holes so that product andinternal cushioning material can add support for carrying (seeFig. 2). If the box must bear all the weight, it is best to positionthe hand holes at

20、 least two (2) in. below the horizontal scoreline of end panels to distribute the compressive forces andavoid failure. When placing hand holes, consider productbalance and box closure method.FIG. 1 Common Hand Hole TypesD 6804 02 (2007)25.3 Some closure methods, such as taping, can affect handhole p

21、lacement. When a hand hole is to be used with a boxstyle such as an RSC, which is to have a tape closure (seePractice D 1974), it is best to allow enough room (2 to 212-in.)for the end-leg of the tape (see Fig. 3). For a Bliss style box,hand holes should be placed just below the top flange (see Fig.

22、4).5.4 Several methods are used to reinforce a box above thehand hole. For example, pressure sensitive, heat activated, andadhesive based products can be used. Some have fiberglass orpolyester yarn reinforcement, some are tensilized, and someare made of heavy kraft paper (see Fig. 5).5.5 When possib

23、le, use curved type hand holes: they willnot tear as easily as the straight top design (see Fig. 4). Thecurved design eliminates a sharp edge at the corners, resultingin a more evenly distributed lifting force across the surface.Note that a different type of grasping device will be requiredwhen test

24、ing curved hand holes as opposed to straight ones (seeX1.3, Apparatus).6. Evaluation6.1 The test methods in Appendix X1 are not ASTMstandards, but are evaluation methods to assist in determiningthe relative performance of hand holes during handling in thedistribution environment. The methods, in exp

25、erimental trials,were shown to have high variability between laboratories;however, within laboratories the methods were useful indetermining relative performance.7.

EVALUATION OF PERFORMANCE OF HAND HOLES IN CORRUGATED BOXESX1.1 Summary of MethodsX1.1.1 Method A, Jerk TestUses free-fall drop test appa-ratus in conjunction with a support ap

28、paratus and graspingdevice(s), imparting a sudden sharp arrested motion (jerk) tothe hand hole area of a corrugated box. A grasping devicesimilar to that shown in Fig. X1.1 provides contact with thehand hole.X1.1.1.1 This method is applicable for testing both one- andtwo-hand lifting of boxes. It is

29、 not intended for horizontalpulling of the box (see Method B, Tensile Test).X1.1.2 Method B, Tensile TestUses tensile testing ma-chines having a constant free-running crosshead speed orconstant extension rate to determine the maximum load carry-ing ability of the hand hole(s) in the tested box. Cont

30、act withthe hand hole is provided by the same type of grasping deviceused for Method A, and the box is fixed to the stationaryportion of the machine.X1.1.2.1 With proper fixturing, this method is applicable totesting one- and two-hand lifting, and horizontal pulling ofboxes.X1.2 Significance and Use

31、X1.2.1 These test methods will assist in determiningwhether hand holes in corrugated boxes will perform tospecific level(s) of handling force(s) expected in the distribu-tion environment during manual handling. These forces can bestatic, that is, a box picked up slowly, or dynamic, a box pickedup or

32、 moved with a jerking motion. These methods may beused to compare different types of hand hole/box construction,or to measure performance to a specified level.X1.2.2 During testing, forces are applied in directions mostfrequently seen in normal manual handling. In addition to thenormal direction of

33、force (usually vertical), other directionscould be diagonal (such as when lifting a box with one hand)and at 90 (such as when boxes are pulled by the hand holerather than lifted).X1.3 ApparatusX1.3.1 Grasping Device:X1.3.1.1 The grasping device shall be similar to that shownin Fig. X1.1. The width s

34、hould be modified to match the widthof the straight portion of the hand hole, up to a maximum widthof 4 in. Hand holes having a curved top edge may requirespecial designs, to be determined by the user.X1.3.1.2 For a vertical jerk or tensile test, two graspingdevices are used, each connected to a spr

35、eader bar that supportsthe two devices at a distance such that the devices hangvertically when lightly engaging both hand holes (see Fig.X1.2).X1.3.1.3 The user must be sure that the grasping devices,spreader bar, and connecting hardware are of sufficient strengthto safely hold the load.X1.3.2 Metho

36、d A, Jerk Test (see Fig. X1.2):X1.3.2.1 Drop Test Apparatus, with a platform or otherfeature which supports a corrugated box, such that the box maybe released for free-fall from a specified height. Supportapparatus for the grasping device must suspend the box at least6 in. (150 mm) above the floor o

37、r test apparatus base. Thesupport apparatus must secure the grasping device(s) soessentially no yielding or elastic stretch occurs when the boxfalls and its motion is arrested by the device(s). A chain orflexible steel cable suspended from a rigid support or overheadhoist may be used for this purpos

38、e.X1.3.2.2 An elastic cord may be used to take up the slack inthe chain or cable to make sure the grasping device(s) stays inthe hand hole(s). The cord shall be stiff enough to just supportthe weight of the fixture at the desired drop height and yetimpart no significant additional force at the botto

39、m of travel,that is, when there is no slack in the chain.X1.3.3 Method B, Tensile Test (see Fig. X1.3):X1.3.3.1 A tensile testing machine capable of producing aconstant cross-head speed or rate of extension shall be used.X1.3.3.2 Machines used for tensile testing shall conform tothe requirements of

40、Practice E4. The forces used in determin-ing the tensile strength shall be within the verified forceapplication range of the testing machine as defined in PracticeE4.X1.3.3.3 A method to determine and record the maximumforce applied during the test shall be provided.NOTE X1.1It may be of interest to

41、 record the amount of energyrequired to cause failure.X1.4 Sampling and Test SpecimensX1.4.1 Selection of a sampling plan depends on the purposeof the testing. The sampling plan from Appendix X2.2.2 ofPractice D 585 is recommended for acceptance criteria. Forpurposes other than acceptance criteria,

42、Practice E 122 isrecommended.X1.4.2 Pack the box with either the actual contents, or adummy load simulating the contents with respect to dimen-sions, weight, center of gravity, moment of inertia, and flowcharacteristics. Close the box the same way it will be used forshipment.X1.4.2.1 For tensile tes

43、ts, fixturing may make it impossibleto use actual contents. The weight, center of gravity, moment ofinertia, and flow characteristics of the contents are not signifi-cant parameters for tensile tests. However, fixturing andcontents must be such that the deformation of the box andstrength of the hand

44、 holes are not affected.X1.5 ConditioningX1.5.1 All test specimens shall be preconditioned, condi-tioned, and tested in accordance with Practice D 4332, or otherspecial conditions as required.D 6804 02 (2007)5FIG.

X1.3 Tensile Test ConfigurationsD 6804 02 (2007)8X1.6 ProcedureX1.6.1 Method A, Jerk Test:X1.6.1.1 Insert the grasping device(s) in the hand hole(s),and raise the filled box so that it is suspended at least 6 in. (150mm) above the floor or drop apparatus base. Note the distancefrom the floor

46、or base to the box, and then use the drop testapparatus to raise the box to the desired free-fall drop height,relative to the free suspended position. An elastic cord may beused to take up the slack in the chain or cable to hold thegrasping device(s) in the hand hole(s). Refer to Fig. X1.2 forgraphi

47、c descriptions of the test configuration.X1.6.1.2 The spreader bar (see Fig. X1.2) must remain in ahorizontal and level position during the test.X1.6.1.3 When conducting the One-Hand Jerk test, the boxclosure method must be the same as intended for actual use.X1.6.1.4 Release the drop test apparatus

48、, allowing the boxto free-fall for the desired drop height until stopped by thegrasping device(s). (WarningWhen a hand hole fails ineither a two-hand or one-hand test, the box and graspingdevices may move in a violent and unpredictable manner.X1.6.1.5 Perform the jerk tests to a prescribed sequence,

49、using a single or multiple constant drop height procedure, or aprogressive drop height procedure. Refer to Test MethodD 5276 Annex A2 for guidance on drop test cycles andprocedures. Typical drop heights for jerk testing range from 0.5to 8 in. (13 to 200 mm), sufficient to produce 40 to 60 in.-lbf(4.5 to 6.8 J) of energy (gross weight 3 drop height). Energylevels may be lower for multiple drop sequences, perhaps aslow as 5 in.-lbf (0.6 J) for repeated drops of a lightly loadedbox.X1.6.1.6 Note the condition of the hand hole area after eachtest, and compare it to
