Physical Requirements7.1 StrengthThe design strength designation of the pipe shall be the D-load to produce the 0.01-in. crack when tested inaccor

36、from 2000 through 3000, and a factor of 1.25 for design strength designations in excessof 3000.NOTE 3As used in this specification, the 0.01-in. crack is a test criterion for pipe tested in three-edge bearing test and is not intended as an indicationof overstressed or failed pipe under installed con

37、ditions.NOTE 4Ultimate strength of concrete pipe in the buried condition is dependent on varying soil bedding factors and varying failure modes and shallnot necessarily have a relationship to the ultimate strength as defined under three-edge bearing conditions.7.2 Test Equipment and FacilitiesThe ma

38、nufacturer shall furnish without charge all samples, facilities, and personnelnecessary to carry out the tests required by this specification.7.3 Pipe Load Tests The tests for crushing strength, when required, shall be made in accordance with Test Methods C497.When alternative methods of load testin

39、g are specified, tests shall be made in accordance with the alternative requirements.8. Dimensions and Permissible Variations8.1 Standard DiametersPipe shall be manufactured in the standard inside diameters listed in Table 1.NOTE 5Diameters other than those shown in Table 1 and diameters larger than

40、 144 in. are possibly available. When such sizes are required, the ownershould contact the manufacturers 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 12 through 24-i

41、n. pipe shall not vary more than 2 % of the design diameterfor 12-in. pipe and 112 % for 24-in. pipe with intermediate size variation being a linear scale between 2 and 112 %. The internaldiameter of sizes 27-in. and larger shall not vary by more than 1 % of the design diameter or 638-in., whichever

42、 is greater. Thesediameter requirements are based on the average of four diameter measurements at a distance of 12-in. from the end of the bell orspigot of the pipe. Diameter verification shall be made on the number of pipe selected for test per Section 11.8.2.2 Reinforcement Placement TolerancesThe

43、 maximum variation in the nominal position of the reinforcement shall be610 % of the wall thickness or 658 in., whichever is greater. Pipe having variations in the position of the reinforcement exceedingthose specified above shall be accepted if the three-edge-bearing strength requirements obtained

44、on a representative sample aremet. In no case, however, shall the cover over the circumferential reinforcement be less than58 in.8.2.3 Length of Two Opposite SidesVariations in the laying length of two opposite sides of pipe shall not be more than14 in.for all sizes through 24-in. internal diameter,

45、 and not more than18 in./ft of internal diameter for all larger sizes, with a maximumof58 in. in any pipe through 84-in. internal diameter, and a maximum of34 in. for 90-in. internal diameter or larger, except wherebeveled-end pipe for laying on curves is specified by the owner.8.2.4 Length of PipeT

46、he underrun in length of a section of pipe shall not be more than18 in./ft with a maximum of12 in.in any length of pipe.TABLE 1 Standard Designated Inside Diameter, in.12 24 36 60 84 108 13215 27 42 66 90 114 13818 30 48 72 96 120 14421 33 54 78 102 126C655 1238.2.5 Wall Thickness TolerancesThe wall

47、 thickness shall be not less than the nominal specified in the design given in 5.1.3by more than 5 % or316 in., whichever is greater.Awall thickness more than that required in the design is not a cause for rejection,except that such pipe shall not be used for the tests required in 7.3.9. Acceptance

48、of Design9.1 Acceptance by Tests of SpecimensThree to five representative specimens, or special test pipe that are shorter than standardproduction pipe, as agreed upon by the owner and manufacturer, shall be tested to the 0.01-in. crack and to ultimate strength andthe results recorded.
