16、ydrostatic heads of 25, 50, 75, 100, and 125 ft measuredto the centerline of the pipe. Designs are provided in Table 1for the above hydrostatic heads combined with external load-ings of 5, 10, 15, and 20 ft (designated A, B, C, and D in Table1) of earth cover over the top of the pipe under specifici

17、nstallation conditions. The specific installation conditions arecovered in Appendix X1. Where the hydrostatic head, externalloadings, and installation conditions vary from those given inTable 1 and Appendix X1, detailed design calculations shall bemade. The design criteria for Table 1 are presented

18、in Appen-dix X2.5. Basis of Acceptance5.1 Acceptability of the pipe in all diameters and classesshall be determined by the results of such material tests as arerequired in 6.2 through 6.9 by crushing tests on cured concretecylinders, by hydrostatic pressure tests on units of the pipe, byjoint leakag

19、e tests, and by inspection during or after manufac-ture to determine whether the pipe conforms to this specifica-tion as to design and freedom from defects.5.2 Age for AcceptancePipe shall be considered ready foracceptance when they conform to the requirements, as indi-cated by the specified tests.6

20、. Materials6.1 Reinforced ConcreteThe reinforced concrete shallconsist of portland cement, mineral aggregates, and water, inwhich steel has been embedded in such a manner that the steeland concrete act together.
