Joints shall be the same type as used inthe adjoining pipe.9.3.2 Wyes and TeesFabricated branches for wyes and teesshall be securely attached to the wall of the pipe and shall beflush with the inside surface of the pipe.10. Physical Requirements10.1 Test SpecimenThe specified number of
33、pipe requiredfor the tests shall be furnished by the manufacturer and shall beselected at random by the owner, and shall be pipe that wouldnot otherwise be rejected under this specification. The selectionshall be made at the point or points designated by the ownerwhen placing the order. The test pip
34、e shall first be freed fromall visible moisture. When dry, each pipe shall be measured andinspected. The results of these observations shall be recorded.10.2 Number and Type of Test SpecimensThe manufac-turer shall furnish pipe for crushing tests, up to 0.5 % of thenumber of pipe of each size includ
35、ed in the order, except thatin no case shall less than two pipes be furnished.10.3 External Load Crushing RequirementsThe crushingstrength of porous nonreinforced concrete pipe shall conformto the requirements prescribed in Table 1 and Table 2. Theindividual results of the various tests for each siz

All tests shall bemade in accordance with Test Methods C497M. Pipe shall beacceptable when all test pipe conform to
37、the specified strengthrequirement. Should any of the test pipe provided in 10.2 failto meet the strength requirement, the manufacturer will beallowed to test two pipe for each pipe that failed, and the pipeshall be acceptable only when all of these additional test pipemeet the strength requirement.1

The internal diameter of pipe manufactured to theConverted English Diameters shall vary not more than 63mmfrom the Converted English Diameter for 102 mm and 152 mmand 66 mm for larger pipe. For pipe manufactured to Con-verted English
46、Diameters, the corresponding Designated Di-ameter shown in Table 4 shall apply for all other requirementsof this specification.12. Repairs12.1 Pipe repaired because of imperfections in manufactureor damage during handling will be acceptable, if in the opinionof the owner, the repaired pipe conforms

Such inspection shall beperformed either at the point of manufacture or delivery.14. Rejection14.1 P
48、ipe shall be subject to rejection on account of failureto conform to any of the specification requirements. It is notprohibited for individual sections of pipe to be rejected becauseof any of the following:14.1.1 Fractures or cracks passing through the wall or joints,except that a single crack not e
49、xceeding 50 mm in length ateither end of a pipe or a single fracture in the joints notexceeding 75 mm in width nor more than 50 mm in length shallnot be considered cause for rejection unless these defects existin more than 5 % of the entire shipment or delivery.14.1.2 The planes of the ends of the pipe are not perpen-dicular to the longitudinal axis, subject to the limits of variationas shown in Table 3.14.1.3 Defects that indicate mixing and molding not inaccordance with 9.1.14.1.4 Cracks sufficient to impair the strength,
