20、e and Use4.1 Dangerous goods (hazardous materials) regulations re-quire performance tests to be conducted on packaging or IBCdesigns before being authorized for use. The regulations do notinclude standardized procedures for conducting performancetests and, because of this, may result in a non-unifor

21、mapproach and differences in test results between testing facili-ties.4.2 The purpose of this standard is to provide guidance andto establish a set of common practices for conducting hydro-static pressure tests on IBC designs subjected to UN certifica-tion testing.4.3 Intermediate bulk container des

22、igns are required to betested in a sequence. This guide focuses on conducting thehydrostatic pressure test, which is preceded in the test sequenceby the leakproofness test. The fittings and adaptors applied tothe container for the hydrostatic pressure test may also be usedfor the leakproofness test.

Equipment5.1 Recommended Test Equipment:5.1.1 Appropriate Packaging Closing Equipment (Cali-brated as Applicable)Closing equipment, such as torquewrench, cover/closure crimping tools, and so forth, to preparethe IBC design for transport.5.1.2 Water Supply Source:5.1.2.1 Water supply source system

24、 should be designed tominimize water pressure fluctuations during the test.5.1.2.2 The water source can be building supplied waterprovided fluctuations in pressure do not occur during the test.5.1.2.3 It is recommended to have a separate water supplytank assembly to enable the use of air pressure ov

25、er the top ofthe water supply. Air pressure may be used to pressurize thewater supply tank to provide adequate water pressure to the testcontainer in a timely fashion. Refer to Fig. 1.5.1.3 Regulator Valve, used to maintain an even pressurethroughout the duration of the test and to maintain proper w

Refer toitems (6) and (7)inFig. 1.5.1.5 Hose or Piping, as required.5.1.6 Pressure Gauge(s), psi/kPa dual marked and cali-brated (digital preferred).5.1.6.1

27、Gauge, to monitor water supply pressure.5.1.6.2 Gauge, to monitor pressure inside the test container.5.1.6.3 All gauges used should be calibrated and have anaccuracy in the appropriate range.5.1.7 Connections (Fitting/Valves, Adaptors, Gaskets, andBushings) or other equally effective means, as neede

Container7.1 Selection:7.1.1 Randomly select an appropriate container to be tested.7.1.2 Visually inspect container to verify that all closures,plugs, gasket, accessories, and so forth match the closinginstructions and to determine if the c

32、ontainer has any blemishesor defects that would affect a proper seal (record any observa-tions). If necessary, clean off gaskets and other closure surfacesto ensure a proper seal is accomplished.7.2 Preparation:7.2.1 Location of Fittings and GaugesCare should betaken not to attach fittings to contai

33、ner embossments or othergeometries that could possibly compromise the integrity of thecontainer or invalidate the test. The report should describe ingeneral how many fittings are used and where fittings andgauges are located. Photo documentation is recommended.NOTE 2To reduce the possibility of inco

34、nsistent results between testsamples, gauges and fittings should be in the same location.D8134 1827.2.1.1 IBC DesignsThe pressure gauges and fittingsshould be located in the highest possible point of the testorientation.7.2.2 Container Setup:7.2.2.1 Drill an appropriate size hole in the test contain

35、er fora water inlet fitting then install the fitting and snug tight witha wrench (see Fig. 2).7.2.2.2 Drill a second hole of appropriate size in the testcontainer for a pressure-monitoring fitting then install thefitting and snug tight with a wrench (see Fig. 2).NOTE 3Both holes and fittings should

36、be installed near the topopening to allow for access through the opening. Make sure you leaveenough room to allow for the closing tool to be used to torque the fill portcap of the IBC (see Fig. 3).7.2.2.3 Connect the pressure gauge assembly to this fittingand remember to place it at the highest poin

37、t of container testorientation (see Fig. 3 and Fig. 4).7.2.2.4 Connect the water supply line to the water inletfitting (see Fig. 3 and Fig. 4).Component ID Description1 Water supply (to pressure tank) with regulator and shut off valve. Hose quick-connects to pressure tank when used.2 Air supply (to

Hose quick-connects to pressure tank when used.3 Tank pressure relief with shut-off valve.4 Gauge to monitor the pressure inside the tank.5 Pressure tank (recommended minimum size of 80 gal) with air over water.6 Water supply with regulator and gauge

41、heopening, discontinue filling. Dry the sealing area and threadarea to ensure there is no trapped water after the closure isapplied (see Fig. 5).7.2.2.7 Measure and record the temperature of the waterinside the test container before sealing the packaging. It isrecommended the water temperature be in

42、 the range of12-23C (see Fig. 5).7.2.2.8 Insert the top closure and secure. All test samplesshall have their fittings, covers, and closures prepared fortransportation in accordance with the manufacturers recom-mended closing instructions (see Fig. 4).7.2.2.9 Vented closures shall be replaced with no

43、n-ventedclosures of the same specification or the vent shall be sealed.Pressure-relief devices shall be removed and their aperturesplugged or shall be rendered inoperative (see Fig. 4).NOTE 4All containers should be prepared completely full with waterbefore starting the test. This may be accomplishe

44、d by venting thecontainer through a fitting while pressurizing the container and allowingthe air to be released.NOTE 5Care should be taken not to cause damage to any part of thesealing surface or thread areas while filling the container.7.2.2.10 When samples are prepared by the client or thirdparty,

45、 a note should be added to the report to indicate whosealed the containers.7.3 Reference Appendix X2 for pressure station preparationprior to starting the test.8. Rate of Pressurization8.1 Test pressure should be determined based on the pres-sures required by the regulations.8.2 After the container

46、has been sealed (in accordance withthe proper closing instructions) and as much air as possible hasbeen removed from the test sample, start pressurizing.8.3 The container shall be gradually pressurized to therequired test pressure using a continuous supply of waterthrough a regulator. The continuous

47、 supply of water shouldremain open to the test sample throughout the entire testduration to allow for the necessary water supply if containerexpansion occurs.8.4 The required test pressure should be accomplishedwithin a suitable length of time based on the IBC design type.It is recommended to be ach

48、ieved in less than 10 min.8.5 The rate of pressurization is dependent on the containerdesign (rigid or composite), size, and its material of construc-tion.8.5.1 The pressure should be applied continuously andevenly and at a rate that will not affect the results of the test.8.5.1.1 The rate should no

49、t be too fast that it would causeundo expansion (shock) to the test sample.8.5.1.2 The rate should not be too slow to cause undostressing over an extended period of time before the requiredtest pressure is reached.8.5.2 Example for Composite IBC with Blow MoldedReceptacleUsing a supply tank pressure of 100 psi and awater supply hose size of34 in. to the test sample a typical 275gal or 330 gal composite IBC should take approximately 7-9min to reach the required test pressure.8.6 For all design types, record the elapsed time to reach therequired test pres
