22、ical sprinklers, porous hose, or by anyother approved method that will keep the pipe moist during thespecified curing period.9.2.3 The manufacturer has the option to combine themethods described in 9.2.1 and 9.2.2 provided the specifiedstrength is attained.9.3 Specials:9.3.1 General RequirementsSpec

23、ial shapes or fittingssuch as wyes, tees, bends, and adapters for use with concretepipe conforming to this specification shall be made of porousor nonporous concrete in such manner as will provide strengthat least equal to the class of the adjacent pipe to which they arejoined; and shall conform to

24、all other requirements specifiedfor pipe of corresponding class and internal diameter, exceptminimum infiltration. Joints shall be the same type as used inthe adjoining pipe.9.3.2 Wyes and TeesFabricated branches for wyes andtees shall be securely attached to the wall of the pipe and shallbe flush w

25、ith the inside surface of the pipe.10. Physical Requirements Physical Requirements10.1 Test SpecimenThe specified number of pipe requiredfor the test 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 s

26、pecification. 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 Type of

27、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 pipe

28、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 purpose of

29、 test. All tests shall bemade in accordance with Test Methods C 497. 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 each p
