17、ical Barriers to Trade (TBT) Committee.1The pail body is usually of a tapered design to provide fornesting of pails during transportation and storage, prior tofilling of contents. After filling of contents, the pail lid isapplied to the pail body, providing a sealed container forstorage and shipment

18、 of the contents. The pail lid may alsohave openings or fitments to allow for dispensing of contentswithout removing the lid. These openings are sealed withclosures.3.2.1.1 DiscussionThe definition for open-head pail forhazardous materials differs (see Section 49 CFR Parts 100 to199).4. Classificati

31、ily when tested in accordance with10.2.5.3.7.10 Special RequirementsPail requirements, additional tothose in 7.2 through 7.9, if needed by a purchaser, must bespecified in the procurement document and as agreed betweenpurchaser and supplier.8. Sampling8.1 LottingA lot shall consist of all pails of o

32、ne size anddesign, produced from the same materials and under essentiallythe same manufacturing conditions and offered for delivery atone time.8.2 Sampling Pails Select sample pails for test at randomfrom a continuous production lot. As a minimum, the numberof pails required is 17 as outlined for de

33、sign qualification tests(see Section 10 and Supplementary Requirements).9. Specimen Preparation9.1 Prepare pail specimens in accordance with NMFC, item258 and UFC Rule 40, where applicable, and as agreedbetween the pail purchaser and supplier.D4504 94 (2018)210. Methods of Testing Pails for Design Q

34、ualification10.1 GeneralThe test procedures described in this sectionare to be used to determine physical performance capability ofa specific design and thereby, to qualify such a design under theperformance requirements of this specification. Additionalsampling and testing of these pails, as may be

35、 agreed uponbetween purchaser and supplier, is not precluded by thissection. Test methods to determine compatibility of the con-tents (lading) with the pail will depend on the specific contentsto be contained. If the available technical information and prioruse experience cannot substantiate an appl

36、ication 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 liquid, that it will not permeate to an extent thata damaging condition could be caused during transportation,storage, and handling.10.2

37、Specific Test Methods for Design Qualification:10.2.1 Drop Strength Test:10.2.1.1 Perform drop strength test on pails intended fornonhazardous liquids 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 PailsFil

38、l 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 andviscosity. Securely close the cover, and stabilize the tempera-ture of the pails and contents at 0F (18C). Then exposethem at that temperature for a mini

39、mum 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 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 ch

40、ime 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 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

41、 5 min after dropping, the pails are rolled for a distance equalto twice its circumference, and no further leakage occurs.Otherwise, leakage or sifting out of contents constitutes failure.NOTE 2Uniform Freight Classification, Rule 40 and National MotorFreight Classification, Item 258 require a 45 an

42、gle at impact.10.2.2 Stacking StrengthThe stacking test shall conformto Test Method D4577. If a compression testing machine isused, it shall be capable 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 Strengt

43、h TestFilltwo sample pails with intended contents, or a material ofsimilar properties, to nominal capacity and close securely as iffor use. Expose the 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

44、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 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

45、 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 test 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 twi

46、ce its circumference and observefor leakage or sifting of contents. Any leakage or sifting ofcontents constitutes failure.NOTE 3The forces for stacking test are a minimum based uponrequirements of NMFC, Item 258 and UFC Rule 40. Consideration shouldbe given to using a stacking force based upon actua

47、l shipping experience.NOTE 4Caution: The potential exists for catastrophic failure causingan instability of the applied top load. Precautionary steps 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 Vib

48、ration Test (Vertical Column Stack ResonanceTest)Test three vertically stacked pails by vibrating asfollows.10.2.3.1 Perform vibration test on pails for nonhazardousliquids and nonliquids in accordance with the vibration testrequirements of NMFC, Item 258, and UFC, Rule 40, using theprocedures of Me

49、thods 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 from 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 repetitive shock test shall conform to MethodsD999 (Method A1).10.2.4.2 Condition Pails Fill ea
