Physical Requirements7.1 StrengthThe design strength designation of the pipeshall be the D-load to produce the 0.01-in. crack when tested inaccordance with Test Methods C 497. The relationship ofultimate strength D-load to the design strength D

32、-load shall bedetermined using a factor of 1.5 for design strength designa-tions up to 2000 lbf/ftft of diameter, a factor varying in linearproportions from 1.5 to 1.25 for design strength designationsfrom 2000 through 3000, and a factor of 1.25 for designstrength designations in excess of 3000.NOTE

33、 3As used in this specification, the 0.01-in. crack is a testcriterion for pipe tested in three-edge bearing test and is not intended asan indication of overstressed or failed pipe under installed conditions.NOTE 4Ultimate strength of concrete pipe in the buried condition isC655092dependent on varyi

34、ng soil bedding factors and varying failure modes andshall not necessarily have a relationship to the ultimate strength as definedunder three-edge bearing conditions.7.2 Test Equipment and FacilitiesThe manufacturer shallfurnish without charge all samples, facilities, and personnelnecessary to carry

35、 out the tests required by this specification.7.3 Pipe Load Tests The tests for crushing strength, whenrequired, shall be made in accordance with Test MethodsC 497. When alternative methods of load testing are specified,tests shall be made in accordance with the alternative require-ments.8. Dimensio

36、ns and Permissible Variations8.1 Standard DiametersPipe shall be manufactured in thestandard inside diameters listed in Table 1.NOTE 5Diameters other than those shown in Table 1 and diameterslarger than 144 in. are possibly available. When such sizes are required,the owner should contact the manufac

37、turers in the area.8.2 Design TolerancesExcept as specified in this section,all permissible design tolerances shall be given in Section 5.8.2.1 Internal DiameterThe internal diameter of 12through 24-in. pipe shall not vary more than 2 % of the designdiameter for 12-in. pipe and 112 % for 24-in. pipe

38、 withintermediate size variation being a linear scale between 2 and112 %. The internal diameter of sizes 27-in. and larger shallnot vary by more than 1 % of the design diameter or 638-in.,whichever is greater. These diameter requirements are based onthe average of four diameter measurements at a dis

39、tance of12-in. from the end of the bell or spigot of the pipe. Diameterverification shall be made on the number of pipe selected fortest per Section 11.8.2.2 Reinforcement Placement TolerancesThe maximumvariation in the nominal position of the reinforcement shall be610 % of the wall thickness or 658

40、 in., whichever is greater.Pipe having variations in the position of the reinforcementexceeding those specified above shall be accepted if thethree-edge-bearing strength requirements obtained on a repre-sentative sample are met. In no case, however, shall the coverover the circumferential reinforcem

41、ent be less than58 in.8.2.3 Length of Two Opposite SidesVariations in thelaying length of two opposite sides of pipe shall not be morethan14 in. for all sizes through 24-in. internal diameter, and notmore than18 in./ft of internal diameter for all larger sizes, witha maximum of58 in. in any pipe thr

42、ough 84-in. internaldiameter, and a maximum of34 in. for 90-in. internal diameteror larger, except where beveled-end pipe for laying on curvesis specified by the owner.8.2.4 Length of PipeThe underrun in length of a section ofpipe shall not be more than18 in./ft with a maximum of12 in.in any length

43、of pipe.8.2.5 Wall Thickness TolerancesThe wall thickness shallbe not less than the nominal specified in the design given in5.1.3 by more than 5 % or316 in., whichever is greater. A wallthickness more than that required in the design is not a causefor rejection, except that such pipe shall not be us

44、ed for thetests required in 7.3.9. Acceptance of Design9.1 Acceptance by Tests of SpecimensThree to five repre-sentative specimens, or special test pipe that are shorter thanstandard production pipe, as agreed upon by the owner andmanufacturer, shall be tested to the 0.01-in. crack and toultimate st

45、rength and the results recorded. Compute the valuesin 9.1.1 and 9.1.2 for both the 0.01-in. crack and the ultimatestrength.9.1.1 Compute the estimated standard deviation, s,byEq1or Eq 2, which equations yield identical values.s 5 =(Xi2 X!2#/n 2 1! (1)s 5 =(Xi22 ( Xi!2/n#/n 2 1! (2)where:Xi= observed

46、 value of the load to produce the 0.01-in.crack (and the load to develop the ultimate strength),X= average (arithmetic mean) of the values of Xi, andn = number of observed values.9.1.2 Compute the minimum allowable arithmetic mean, Xs,by Eq 3. In Eq 3, the value of the estimated standard deviation,s

47、, shall be as calculated by Eq 1 or Eq 2 or equal to 0.07L,whichever is greater.Xs5 L 1 1.07 s (3)where:L = specification limit (specified D-load).9.1.3 The pipe design shall be acceptable if the arithmeticmean Xfor the 0.01-in. crack and ultimate strength is equal toor greater than the computed val

48、ues of Xs, and if all the testedspecimens meet or exceed the specification limit, or if all testspecimens meet or exceed the design strength.9.2 Alternative Acceptance MethodThe manufacturershall be allowed to request approval of designs based onempirical evaluations of the strength of the pipe incl

49、uding, butnot limited to, designs based on interpolation between designsapproved in accordance with 9.1, or designs evaluated on thebasis of tests other than the three-edge-bearing test method.Acceptance of design tests need not be performed for eachcontract or order.10. Acceptance of Pipe by Load Testing10.1 Lot SamplingWhen the acceptance is to be in accor-dance with 4.1.1, randomly select from the lot a sample of thesize listed in Table 2 and test each specimen to the 0.01-in.TABLE 1 Standard Designated Inside Dia
