Physical Requirements Physical Requirements10.1 Test SpecimensSpecimens for tests shall be full-sizepipe which shall in every respect conform to the inspectionrequirements prescribed in this specification.

26、10.2 Number and Type of Tests Required:10.2.1 The specimens to be tested shall be selected atrandom by the owner at the place of manufacture, and shall betested in advance of shipment. The manufacturer shall furnishspecimens for purpose of tests, without charge, up to 0.5 % ofthe number of pipe of e

27、ach size included in the order, exceptthat in no case shall less than two specimens be furnished, themanufacturer bearing all expense of testing each pipe. Shoulda larger number of specimens be tested upon demand of theowner or manufacturer, then the cost of such additional testspecimens and the exp

28、ense of testing shall be borne by theparty making such demand.10.2.2 The owner shall specify the proportion of irrigationpipe specimens that shall be subjected to the three-edge-bearing load tests, and the proportion that shall be subjected tothe hydrostatic test.10.2.3 All drainage pipe to be teste

29、d shall be subjected tothe three-edge-bearing load tests, and one half of the number ofpipe so tested shall be subjected to the Test Method A or TestMethod B absorption test in accordance with Test MethodsC 497M, or other absorption test approved by the owner.10.3 External Load Test RequirementsThe

If mutually agre

33、ed upon between the manu-facturer and owner, other types of bearings such as hard rubberblocks or sand-filled high-pressure hose are acceptable. Theuser of this specification is advised that sand or other loose finematerial may be spread along the length of the crown of thepipe to equalize the upper

34、 bearing.10.3.2 The load shall be applied continuously until thestrength specified in Table 1 or 2 is reached. The pipe shall notbe allowed to stand under load longer than is required to applythe load and to observe and record it. The pipe shall besurface-dry when tested. Tests shall not be made on

35、frozenpipe.10.4 Absorption TestTest specimens shall be subjected tothe boiling absorption test in accordance with Test MethodsC 497M. For Test Method A, three test specimens shall betaken from each pipe unit to be tested; one of the pieces shallbe taken from one end of the pipe, another piece from t

36、heopposite end, and the third piece from near the center. For TestMethod A, each test specimen shall be free of visible cracks,shall have a minimum area of not less than 130 cm2asmeasured on one surface. The average absorption of the threespecimens shall be considered to be the absorption for thatpi

37、pe. The absorption of concrete drainage pipe as determinedby the boiling absorption test shall not exceed 9 % for TestMethod A or 8.5 % for Test Method B.10.5 Hydrostatic Tests:10.5.1 Irrigation pipe, when tested in accordance with thehydrostatic test procedures of Test Methods C 497M, shallsustain

38、an internal hydrostatic pressure of 70 kPa for 10 minwithout excessive leakage through the wall of the pipe.Moisture appearing on the surface of the pipe in the form ofpatches or beads adhering to the surface shall not be consideredas excessive leakage. Slow-forming beads of water frompinholes that

39、result in minor dripping and slight pinhole spurtsthat will not interfere with the use of the pipe in service will notbe cause for rejection.10.5.2 The pipe shall not fail when, after completion of theportion of the test described in 10.5.1, the pressure is increasedto the minimum hydrostatic pressu

40、re specified in Table 1.10.6 RetestsIrrigation pipe shall be acceptable under theload and hydrostatic test requirements when all test specimensconform to the test requirements. Drainage pipe shall beacceptable under the load and absorption test requirementswhen all the test specimens conform to the

41、test requirements.Should any of the initial test specimens fail to meet the testrequirements, the manufacturer will be allowed a retest on twoadditional specimens for each initial specimen that failed, andthe tested lot will be acceptable only if all retest specimensmeet the test requirements. In th

42、e event these retest specimensdo not fully conform to the test requirements, the entire lotshall be rejected without further test. The manufacturer shallbear all the expense of retesting.11. Permissible Variations11.1 Internal DiameterSee Table 3.At the manufacturersoption, the internal diameter sha

43、ll be one of two alternatives,the Designated Diameter or the Converted English Diameter.Pipe sections that are intended to be jointed to each other shallbe furnished with the same internal diameter alternative. Theinternal diameter of pipe manufactured to the DesignatedDiameters shall vary from the

44、Designated Diameter not morethan 65 mm for 150 mm pipe and smaller, 67 mm for 200 mmpipe to 450 mm pipe, and 68 mm for 500 mm pipe and larger.The internal diameter of pipe manufactured to the ConvertedEnglish Diameter shall vary from the Converted EnglishDiameter not more than 65 mm for 152 mm pipe

45、and smaller,67 mm for 203 mm pipe to 457 mm pipe, and 68 mm for 508mm pipe and larger. For pipe manufactured to ConvertedEnglish Diameters, the corresponding Designated Diametershown in Table 3 shall apply for all other requirements of thisspecification.11.2 Wall ThicknessThe minimum wall thickness

46、of thepipe shall be not more than 5 % or 2 mm, whichever is greater,less than the wall thickness specified in Table 1 or Table 2 forthe applicable class of pipe, or as specified in an approvedalternative design.12. Workmanship and Finish12.1 Pipe shall be substantially free of fractures and surfacer

47、oughness.13. Repairs13.1 Pipe repaired because of occasional imperfections inmanufacturing or accidental injury during handling and will beacceptable if, in the opinion of the owner, the repairs are soundand properly finished and cured and the repaired pipe conformsto the requirements of this specif

48、ication.14. Inspection14.1 The quality of all materials and the finished pipe shallbe subject to inspection and approval by the owner.15. Rejection15.1 Individual pipe units shall be subject to rejection onaccount of failure to conform to any of the specificationrequirements or on account of any of
