Physical Requirements Physical Requirements10.1 Test SpecimenThe specified number of 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 t

31、his specification. The selectionshall be made at the point or points designated by the ownerwhen placing the order. The test pipe 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 Typ

32、e of Test SpecimensThe manufac-turer shall furnish pipe for crushing tests, up to 0.5 % of thenumber of pipe of each size included 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

33、pipe shall conformto the requirements prescribed in Table 1 and Table 2. Theindividual results of the various tests for each size of pipe andfor each shipment and plant shall be tabulated separately. Thecrushing strength shall ordinarily be applied to not less than75 % of the pipe received for purpo

34、se of test. All tests shall bemade in accordance with Test Methods C 497M. Pipe shall beacceptable when all test pipe conform to 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

35、each pipe that failed, and the pipeshall be acceptable only when all of these additional test pipemeet the strength requirement.10.4 Infiltration RequirementInfiltration (or porosity)shall conform to the requirements in Table 1 or Table 2.10.4.1 The test pipe shall be placed with a spigot end downon

36、 a soft rubber nonpermeable mat, or its equivalent, andweighted or clamped down if necessary to prevent the escapeof water through the spigot end of the pipe.10.4.2 Water shall be introduced into the pipe, and thedistance above the bottom of the porous section at which thewater level becomes constan

37、t shall be determined. The rate offlow shall be at least equal to the required minimum infiltrationfor1mofpipe as given in Table 1 or Table 2.10.4.3 The rate of infiltration per metre of pipe shall bedetermined as follows:LITRES/s 5 L/h (1)where:LITRES/s = infiltration rate in litres per second per

38、metreof pipe,L = litres per second of flow introduced into thetest pipe, andh = height in metres from the bottom of theporous section of the pipe at which the levelof water becomes constant.10.5 Test EquipmentThe manufacturer shall furnish allequipment, facilities, and personnel necessary to perform

39、 at hisplant the tests specified in Section 10. In the event that theowner elects to have tests performed at any other location, themanufacturer will not be required to furnish equipment, facili-ties, nor personnel.11. Permissible Variations11.1 Permissible variations from the dimensions describedin

40、 Table 1 and Table 2 shall not exceed those stated in Table 3and 11.2. This is not to be construed, however, that heavierwall thickness pipe cannot be furnished at the option of themanufacturer. Pipe intended to be straight shall not havevariation in alignment of more than 10 mm/m of length.11.2 Int

41、ernal DiameterSee Table 4.At the manufacturersoption, the internal diameter shall be one of two alternatives,the Designated Diameter or the Converted English Diameter.Pipe sections that are intended to be jointed to each other shallFIG. 1 Joint DimensionsTABLE 4 Internal DiametersDesignatedDiameter,

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 manuf

44、actured to Con-verted English 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 owne

45、r, the repaired pipe conforms to the requirements ofthis specification.13. Inspection13.1 The quality of all materials, the process of manufac-ture, and the finished pipe shall be subject to the inspection andapproval by the owner. Such inspection shall be performedeither at the point of manufacture

46、 or delivery.14. Rejection14.1 Pipe 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,

47、except that a single crack not exceeding 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

48、 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, durability, orserviceability of the pi
