16、ot include requirements for pipe andfittings intended to be used to vent combustion gases.5. Materials and Manufacture5.1 This specification covers CPVC pipe fittings made fromcompounds meeting the requirements of Class 23447 and Class23448 as defined in Specification D1784.NOTE 3Mechanical strength

17、, heat resistance and flammability re-quirements are covered in Specification D1784.5.2 Rework MaterialThe manufacturers shall use onlytheir own clean rework fitting material, and the fittings pro-duced shall meet all the requirements of this specification.6. Requirements6.1 Dimensions and Tolerance

18、s:6.1.1 Fitting sockets, inside diameters (waterways), mini-mum wall thicknesses, and dimensions shall be as shown inTables 1-6 when measured in accordance with Test MethodD2122.6.1.2 When multistep reducer bushings are cored out, theinner socket shall be reinforced from the outer wall by aminimum o

19、f three ribs extending from the top of the innersocket to the deepest extremity of the coring. The transitionfromDtoDJ(Table 3) shall be straight, tapered as shown, orradiused. A positive taper in the same direction of the taper inthe socket on the outside diameter of the bushing is optional(see XA/

20、XB in Table 3). Any point measured along the outsidediameter of the bushing (between XA and XB) shall not fallbelow minimum pipe OD.6.1.3 The minimum wall thickness of fittings shall be 125 %of the minimum wall thickness of the corresponding size ofSchedule 80 pipe for which they are designed to be

21、used,except that for the socket, the wall thickness shall be at leastequal to the minimum wall thickness of the corresponding sizeof Schedule 80 pipe.6.1.4 The minimum inside diameter of the fittings shall benot less than the minimum specified inside diameter of thecorresponding size of Schedule 80

22、pipe. This is calculated asfollows:minimum OD! 2 2 3 maximum wall! 5 minimum ID (1)6.1.5 Minimum dimensions have zero negative tolerance.Tolerances on other dimensions are shown in Tables 1 and 3.6.1.6 Fitting Not IllustratedAll fittings, whether illus-trated in Tables 1-5 or not, shall maintain the

23、 dimensionsconforming to 6.1 and 6.2.6.2 ThreadsFor all fittings having taper pipe threads,threads shall conform to Specification F1498 and be gaged inaccordance with 8.4.6.3 Burst Pressure:6.3.1 The minimum burst strength of the fittings shall be notless than that calculated for the size and wall t

24、hickness of thepipe with which it is to be used, when calculated from thefollowing equation and using a stress of 6400 psi for 8in. andsmaller fittings, and a stress of 5100 psi for fittings larger than8in.:S 5 PDO2 t!/2t (2)where:S = hoop stress, psi (MPa),P = internal pressure, psi (MPa),DO= avera

25、ge outside diameter, in. (mm), andt = minimum wall thickness, in. (mm).Fittings tested in accordance with 8.5 shall withstand theminimum burst pressure shown in Table 6.6.3.2 Pressures shown are minimum burst pressures and donot imply rated working pressures. The burst pressure shall beused only as

26、an indication of quality.7. Workmanship, Finish, and Appearance7.1 The fittings shall be homogeneous throughout and freeof cracks, holes, foreign inclusions, or other defects. Thefittings shall be as uniform as commercially practicable incolor, opacity, density, and other physical properties.8. Test

27、 Methods8.1 ConditioningCondition of test specimens at 73.4 63.6F (23 6 2C) and 506 5 % relative humidity for not lessthan 40 h prior to test in accordance with Procedure A ofPractice D618, for those tests where conditioning is required.8.2 Test ConditionsConduct tests in the standard labora-tory at

28、mosphere of 73.4 6 3.6F (23 6 2C) and 50 6 5%relative humidity, unless otherwise specified in the test meth-ods or in this specification.8.3 SamplingA sufficient quantity of fittings as agreedupon between the seller and the purchaser shall be selected atrandom from each lot or shipment and tested to

29、 determine thatthe basic design is in conformance with this specification.NOTE 4For individual orders or specifications where supplementaltests are required, only those tests and numbers of tests specifically agreedupon between the purchaser and the seller need be conducted.8.4 ThreadsAll taper pipe

30、 threads shall be gaged inaccordance with Specification F1498.8.5 Burst PressureDetermine the minimum burst pressurein accordance with Test Method D1599, Procedure B. The timeof testing each specimen shall be between 60 and 70 s.9. Retest and Rejection9.1 If the results of any test(s) do not meet th

31、e requirementsof this specification, the test(s) shall be conducted again onlyby agreement between the purchaser and the seller. Under suchagreement, minimum requirements shall not be lowered,changed, or modified, nor shall specification limits be changed.If upon retest, failure occurs, the quantity

32、 of product repre-sented by the test(s) does not meet the requirements of thisspecification.10. Marking10.1 Quality of MarkingThe markings shall be applied tothe fitting in such a manner that they remain legible undernormal handling and installation practices.10.2 Content of Marking:10.2.1 Fittings
