29、r, must bespecified in the procurement document and as agreed betweenpurchaser and supplier.8. Sampling8.1 LottingA lot shall consist of all pails of one size anddesign, produced from the same materials and under essentiallythe same manufacturing conditions and offered for delivery atone time.8.2 Sa

30、mpling Pails Select sample pails for test at randomfrom a continuous production lot. As a minimum, the numberof pails required is 17 as outlined for design qualification tests(see Section 10 and Supplementary Requirements).9. Specimen Preparation9.1 Prepare pail specimens in accordance with NMFC, it

31、em258 and UFC Rule 40, where applicable, and as agreedbetween the pail purchaser and supplier.10. Methods of Testing Pails for Design Qualification10.1 GeneralThe test procedures described in this sectionare to be used to determine physical performance capability ofa specific design and thereby, to

32、qualify such a design under theperformance requirements of this specification. Additionalsampling and testing of these pails, as may be agreed uponbetween purchaser and supplier, is not precluded by thissection. Test methods to determine compatibility of the con-tents (lading) with the pail will dep

33、end on the specific contentsto be contained. If the available technical information and prioruse experience cannot substantiate an application decision, itshall be the responsibility of the shipper of the filled pail toensure that the content is compatible with the pail, and that ifthe content is li

34、quid, that it will not permeate to an extent thatD4504 94 (2011)2a damaging condition could be caused during transportation,storage, and handling.10.2 Specific Test Methods for Design Qualification:10.2.1 Drop Strength Test:10.2.1.1 Perform drop strength test on pails intended fornonhazardous liquid

35、s and nonliquids as follows:10.2.1.2 Perform drop tests in accordance with Test MethodD5276 (without the rupture hazard).10.2.1.3 Conditioning PailsFill each of nine pails to nomore than the marked gross weight at normal outage with thematerial to be contained, or a material of similar density andvi

36、scosity. Securely close the cover, and stabilize the tempera-ture of the pails and contents at 0F (18C). Then exposethem at that temperature for a minimum of 4 h. At the end ofthe temperature conditioning period, remove the pails andimmediately perform the drop test.10.2.1.4 Drop Test Procedure (see

37、 Test Method D5276)Test the pails with a 4 ft. (1.22 m) drop. Use three pails perorientation: ( 1) The pail striking flat on its side, (2)Onthebottom chime with the center of gravity of the pails directlyabove the point of impact, and (3) The pail striking flat on thebottom. Do not use any one pail

38、for more than one drop. Forpails containing liquid, a loss of a few drops through theclosure or gasket area at impact is not to be considered failureif 5 min after dropping, the pails are rolled for a distance equalto twice its circumference, and no further leakage occurs.Otherwise, leakage or sifti

39、ng out of contents constitutes failure.NOTE 2Uniform Freight Classification, Rule 40 and National MotorFreight Classification, Item 258 require a 45 angle at impact.10.2.2 Stacking StrengthThe stacking test shall conformto Test Method D4577. If a compression testing machine isused, it shall be capab

40、le of applying a constant force to anaccuracy of 61 % when determined in accordance with Prac-tices E4.10.2.2.1 Conditioning Pails for Stacking Strength TestFilltwo sample pails with intended contents, or a material ofsimilar properties, to nominal capacity and close securely as iffor use. Expose th

41、e filled pails to a temperature of at least130F (54.4C) for 4 h after its contents have attained atemperature of at least 130F. Immediately proceed to test forstacking strength.10.2.2.2 Stacking Strength Test Procedure (see Test MethodD4577)Stack the one pail on top of the other on a flathorizontal

42、surface in an ambient temperature environment of73.4 6 3.6F (23 6 2C).Apply a top-load mass of 600 lb (272kg) evenly to the top rim of the top pail and leave in place fora minimum of 48 h. Observe for collapse, leakage of contents,and overall stack deflection of both pails at the conclusion ofthe te

43、st period of 48 h. Remove the top pail, then after waitingfor a minimum of 5 min, turn the bottom pail on its side, rollit a distance equivalent to twice its circumference and observefor leakage or sifting of contents. Any leakage or sifting ofcontents constitutes failure.NOTE 3The forces for stacki

44、ng test are a minimum based uponrequirements of NMFC, Item 258 and UFC Rule 40. Consideration shouldbe given to using a stacking force based upon actual shipping experience.NOTE 4Caution: The potential exists for catastrophic failure causingan instability of the applied top load. Precautionary steps

45、 should be taken(that is, through restraining the top load) to reduce the chance of injury tothe operator or damage to surrounding equipment.10.2.3 Vibration Test (Vertical Column Stack ResonanceTest)Test three vertically stacked pails by vibrating asfollows.10.2.3.1 Perform vibration test on pails

46、for nonhazardousliquids and nonliquids in accordance with the vibration testrequirements of NMFC, Item 258, and UFC, Rule 40, using theprocedures of Methods D999, Method C, but restricting theresonant frequency dwell to a vertical linear motion for aperiod of 1 h.10.2.3.2 ResultsRemove each pail fro

47、m the table at onceafter vibrating, and turn it on its side. Then roll it a distanceequal to twice its circumference. Observe for leakage or siftingof contents. Failure of any pail or leakage shall be cause forrejection of the lot (see Section 12).10.2.4 Repetitive Shock Test (Optional):10.2.4.1 The

48、 repetitive shock test shall conform to MethodsD999 (Method A1).10.2.4.2 Condition Pails Fill each of three pails to nomore than the marked gross weight at normal outage with thematerial to be contained, or a material of similar density andviscosity. Securely close the cover and condition to 73.4 63

49、.6F (23 6 2C).10.2.4.3 Perform the repetitive shock test on three pails,oriented in their normal shipping position, in accordance withMethods D999, Method A1, for a period of 1 h. Remove thepails from the table at once after vibrating. Then turn the pailson their sides and rotate them a distance equal to twice itscircumference. Observe for leaking or sifting of contents. Anyleakage or sifting of contents constitutes failure.10.2.5 Compatibility, Permeation, and Environmental StressCrack ResistanceFor each application involving contents
