16、nclude 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, he
17、at 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 Tolerances:6.
18、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 of th
19、ree 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.6.1.3 The m
20、inimum 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 used,except that for the socket, the wall thickness shall be at leastequal to the minimum wall thickness of the corresponding sizeof Schedule 8
21、0 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 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.Tolera
22、nces 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 dimensionsconforming to 6.1 and 6.2.6.2 ThreadsFor all fittings having taper pipe threads,threads shall conform to Specification F1498 and be
23、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 thickness of thepipe with which it is to be used, when calculated from thefollowing equation and using a stress of 6400 psi for 8in. andsmaller
24、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= average outside diameter, in. (mm), andt = minimum wall thickness, in. (mm).Fittings tested in accordance with 8.5 shall withstand theminimum burst
25、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 an indication of quality.7. Workmanship, Finish, and Appearance7.1 The fittings shall be homogeneous throughout and freeof cracks, holes, forei
26、gn inclusions, or other defects. Thefittings shall be as uniform as commercially practicable incolor, opacity, density, and other physical properties.8. Test 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 i
27、n accordance with Procedure A ofPractice D618, for those tests where conditioning is required.8.2 Test ConditionsConduct tests in the standard labora-tory atmosphere 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 Sa
28、mplingA sufficient quantity of fittings as agreedupon between the seller and the purchaser shall be selected atrandom from each lot or shipment and tested to determine thatthe basic design is in conformance with this specification.NOTE 4For individual orders or specifications where supplementaltests
29、 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 threads shall be gaged inaccordance with Specification F1498.8.5 Burst PressureDetermine the minimum burst pressurein accordance with Test Met
30、hod 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 the requirementsof this specification, the test(s) shall be conducted again onlyby agreement between the purchaser and the seller. Under suchagre
31、ement, minimum requirements shall not be lowered,changed, or modified, nor shall specification limits be changed.If upon retest, failure occurs, the quantity of product repre-sented by the test(s) does not meet the requirements of thisspecification.10. Marking10.1 Quality of MarkingThe markings shal
32、l 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 shall be marked with the following:10.2.1.1 Manufacturers name or trademark,F439 122TABLE 1 Tapered Sockets for CPVC Pipe Fittings, Schedule 80
