4、.2 The products covered by this specification are intendedfor use with the distribution of pressurized liquids only, whichare chemically compatible with the piping materials. Due toinherent hazards associated with testing components and sys-tems with compressed air or other compressed gases, someman
5、ufacturers do not allow pneumatic testing of their products.Consult with specific product/component manufacturers fortheir specific testing procedures prior to pneumatic testing.NOTE 2Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious s
6、afteyhazards should a system fail for any reason.1.3 Fitting such as unions, flanges, special plastic-to-metaltransitions and appurtenances intended for use with PVCpiping are covered under specification F 1970.1.4 The text of this specification references notes, footnotes,and appendixes which provi
7、de explanatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.5 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are providedfor information only.1.6 The
8、following safety hazards caveat pertains only tothe test method portion, Section 7, of this specification. Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and hea

16、tion forpoly(vinyl chloride) plastic is PVC.4. Classification4.1 GeneralThis specification covers Schedule 40 PVCpipe fittings, made from four PVC plastic compounds andintended for use with Iron Pipe Size (IPS) outside-diameterplastic pipe.4.1.1 Fittings covered by this specification are normallymol
17、ded. In-line fittings, such as couplings, bushings, caps,nipples, etc., shall be molded or machined from extruded stock.4.1.2 Fittings fabricated by welding are not included in thisspecification.5. Materials5.1 This specification covers PVC pipe fittings made fromfive PVC plastics as classified in S
18、pecification D 1784. Theseare PVC 12454, 12454, 13354, 11443, and 14333.5.2 CompoundThe PVC plastic compound shall meet therequirements of PVC 12454, 12454, 11443, or 14333, asdescribed in Specification D 1784.NOTE 3Mechanical strength, heat resistance, flammability, andchemical resistance requireme
19、nts are covered in Specification D 1784.5.3 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. Requirements Requirements6.1 Dimensions and Tolerances:6.1.1 Fitting sockets inside d
20、iameters (waterways), mini-mum wall thicknesses, and dimensions shall be as shown inTable 1, Table 2, and Table 3 when measured in accordancewith Test Method D 2122.6.1.2 When multistep reducer bushings are cored out, theinner socket shall be reinforced from the outer wall by aminimum of three ribs
21、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 minimum wa
22、ll thickness of fittings shall be 125 %of the minimum wall thickness of the corresponding size ofSchedule 40 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 40 pipe. F
23、or any threaded fitting the minimum wallthickness of the threaded portion shall be at least equal to thethickness of material under the thread root of threaded Sched-ule 80 pipe of the same size.6.1.4 The minimum inside diameter of the fittings shall benot less than the minimum specified inside diam
24、eter of thecorresponding size of Schedule 40 pipe. Any fitting having amale thread shall have an internal diameter not larger thanSchedule 80 pipe of the same size.6.1.5 Minimum dimensions have zero negative tolerance.Tolerances on other dimensions are shown in Table 1 and Table3.6.2 ThreadsFor all
25、fittings having taper pipe threads,threads shall conform to Specification F 1498 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 thickness of thepipe with which it is to be used, when c
26、alculated from thefollowing equation:S 5 P DO2 t!/2t (1)where:S = hoop stress, psi (or MPa),P = internal pressure, psi (or MPa),DO= average outside diameter, in. (or mm), andt = minimum wall thickness, in. (or mm).Fittings tested in accordance with 8.5 shall withstand theminimum burst pressure shown
27、 in Table 4.6.3.2 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, foreign inclusions,
28、 or other defects. Thefittings shall be as uniform as commercially practicable incolor, opacity, density, and other physical properties.8. Test Methods8.1 ConditioningCondition the test specimens at 73 63.6F (23 6 2C) and 50 6 5 % relative humidity for not lessthan 40 h prior to test in accordance w
29、ith Procedure A ofPractice D 618, for those tests where conditioning is required.8.2 Test ConditionsConduct tests in the Standard Labora-tory Atmosphere of 73 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 suffici
30、ent 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, only those tests andnumbers of tests
31、specifically agreed upon between the purchaser and theseller need be conducted.8.4 ThreadsAll taper pipe threads shall be gaged inaccordance with Specification F 1498.8.5 Burst PressureDetermine the minimum burst pressurein accordance with Test Method D 1599. The pressure shall beapplied at a unifor
32、m rate such that the minimum allowableburst pressure is attained in 60 or 70 s.NOTE 5The time-to-failure may exceed 70 s.8.5.1 ApparatusFittings shall be tested while held in atest jig constructed in such a manner as to seal the socket bymeans of O-rings, or gaskets but not to reinforce or support t
33、heD 2466 062fittings, except where contact is necessary because of the shapeof the fitting to keep the fitting in the test jig. Such contact shallbe held to the minimum. The socket plug portion of the testfixture must extend one third to two thirds of the socket depth.Failure of any part of the test
34、 apparatus does not constitutefailure of the fittings.9. Retest and Rejection9.1 If the results of any test(s) do not meet the requirementsof this specification, the tests(s) shall be conducted again onlyby agreement between the purchaser and seller. Under suchagreement, minimum requirements shall n
35、ot 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 Fittings shall be marked with the following:10.1.1 Manufacturers name
36、or trademark,10.1.2 Material designation PVC I for PVC 12454-B, PVC12 for PVC 12454-C, PVC 13 for PVC 13354-C and 11443-B,and PVC II for PVC 14333-D,10.1.3 Fittings intended for the transport of potable watershall include the seal or mark of the laboratory making theevaluation for this purpose.10.1.
