  Designation: D 2846/D 2846M – 99 e 1  An American National Standard Standard Specification for Chlorinated Poly(Vinyl Chloride) (CPVC) Plastic Hot- andCold-Water Distribution Systems 1 This standard is issued under the fixed designation D 2846/D 2846M; the number immediately following the designation indicates theyear of srcinal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon ( e ) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. e 1 N OTE —Table 4 was editorially corrected in November 2004. 1. Scope 1.1 This specification covers requirements, test methods,and methods of marking for chlorinated poly(vinyl chloride)plastic hot- and cold-water distribution system componentsmade in one standard dimension ratio and intended for waterservice up to and including 180°F (82°C). These componentscomprise pipe and tubing, socket-type fittings, street fittings,plastic-to-metal transition fittings, solvent cements, and adhe-sives. Requirements and methods of test are included formaterials, workmanship, dimensions and tolerances, hydro-static sustained pressure strength, and thermocycling resis-tance. The components covered by this specification areintended for use in residential and commercial, hot and cold,potable water distribution systems.1.2 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 somemanufacturers do not allow pneumatic testing of their products.Consult with specific product/component manufacturers fortheir specific testing procedures prior to pneumatic testing. N OTE  1—Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safteyhazards should a system fail for any reason. 1.3 The text of this specification references notes, footnotes,and appendixes which provide explanatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.4 The values stated in either inch-pound or SI units are tobe regarded separately as standard. Within the text, SI units areshown in brackets. The values stated in each system are notexact equivalents; therefore, each system shall be used inde-pendently of the other. Combining values from the two systemsmay result in nonconformance with the specification. N OTE  2—Suggested hydrostatic design stresses and hydrostatic pres-sure ratings for pipe, tubing, and fittings are listed in Appendix X1.Design, assembly, and installation considerations are discussed in Appen-dix X2. An optional performance qualification and an in-plant qualitycontrol program are recommended in Appendix X3. 1.5 The following safety hazards caveat pertains only to thetest method portion, Sections 9 and 10, of this specification: This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use. 2.

Terminology 3.1  Definitions: 3.1.1  General —Definitions used in this specification are inaccordance with Terminology F 412, unless otherwise speci-fied. The abbreviation for chlorinated poly(vinyl chlo-ride) isCPVC. Plastic tubing denotes a particular diameter schedule of plastic pipe in which the outside diameter of the tubing is equalto the nominal size plus  1  ⁄  8  in. (3.18 mm).3.1.2  relation between standard dimension ratio, stress, and internal pressure —the following expression is used to relatestandard dimension ratio, stress, and internal pressure for pipeand tubing: 2 S/P  5  R  2  1 (1) or 2  S/P  5 ~  D 0  /t   ! 2  1 (2) where: S   = stress in circumferential or hoop direction, psi(MPa), P  = internal pressure, psi (MPa),  D  0  = average outside diameter, in. (mm), t   = minimum wall thickness, in. (mm), and  R  = standard dimension ratio, SDR3.1.3  standard dimension ratio (SDR) —a selected series of numbers in which the average outside diameter to minimumwall thickness dimension ratios are constant for all sizes of pipe and tubing in each standard dimension ratio, and whichare the ANSI Z17.1 Preferred Number Series 10 modified by+1. SDR fittings shall by definition be equivalent in minimumsocket wall thickness to the minimum wall thickness of thecorresponding SDR and size of pipe or tubing, and theminimum body wall thickness shall be 125 % of that value.3.1.4  standard material designation code —the chlorinatedpoly(vinyl chloride) material designation code shall consist of the abbreviation CPVC followed by two digits indicating theASTM type and grade in Arabic numerals. Where necessary, athird and fourth digit shall be added to indicate the hydrostaticdesign stress for water at 73°F [23°C] in units of 100 psi [0.69MPa]. 4. Classification 4.1  Pipe ,  Tubing ,  and Fittings —This specification classifiesCPVC 4120 pipe, tubing, and fittings by a single standarddimension ratio which shall be SDR 11, by a maximumcontinuous use temperature which shall be 180°F [82°C] andby nominal pipe or tubing diameters from  1  ⁄  4  in. [9.5 mm]through 2 in. [50 mm].4.2  Plastic-to-Metal Transition Fittings —This specificationclassifies CPVC plastic-to-metal transition fittings intended foruse up to and including 180°F [82°C] as CPVC-180°F on thebasis of resistance to failure by thermocycling.4.3  Solvent Cements and Adhesives — This specificationclassifies solvent cements and adhesives meeting the require-ments contained herein as CPVC Solvent Cement or CPVCAdhesive. 5. Materials 5.1  Basic Materials Description —Chlorinated poly(vinylchloride) plastics used to make pipe, tubing, and fittingsmeeting the requirements of this specification are categorizedby two criteria; namely, basic short-term properties, andlong-term hydrostatic strength. Sections 5.1.1 and 5.1.2 respec-tively define these categories.5.1.1  Basic Short-Term Properties —This specification cov-ers CPVC 41 pipe, tubing, and fittings made from plasticmaterials meeting the mechanical strength, heat resistance,flammability, and chemical resistance requirements for CPVC23447-B in Specification D 1784. N OTE  3—CPVC 23447-B was formerly designated as CPVC Type IVGrade 1, and is herein designated as CPVC 41. This is also used inmarking pipe, tubing, or fittings. 5.1.2  Long-Term Hydrostatic Strength — This specificationcovers CPVC 41 pipe, tubing, and fittings which are furtherdefined by hydrostatic design stress as CPVC 4120. Pipe andtubing are so defined on the basis of long-term hydrostaticstrength tests and are made from compounds having anestablished 180°F [82°C] hydrostatic design stress of 500 psi[3.45 MPa] or greater in accordance with Test Method D 2837.Fittings are so defined by hydrostatic sustained pressure testson fitting assemblies, required by this specification (see 6.2),based on the hydrostatic strength of the corresponding pipe ortubing. N OTE  4—No hydrostatic design stress, as such, exists for fittings untilsuch time as long-term hydrostatic strength test methods for fittings aredeveloped. 5.2  Rework Material —Clean rework material generatedfrom the manufacturer’s own tube or fitting production may beused by the same manufacturer provided the pipe, tubing, orfittings meet all the requirements of this specification. 6.

Calculated SDR 11 fitting wall thick-nesses that fall below 0.102 in. [2.59 mm] for the fitting socketbottom, or 0.128 in. [3.25 mm] for the fitting body, shall bearbitrarily increased to these values.6.1.1.2  Interference Fit  —The diameters and tolerances inTable 1 and Table 2 provide for socket-type joints having aninterference fit based on the major diameter of pipe and tubinghaving a degree of out-of-roundness.6.1.1.3  Out-of-Roundness —The maximum out-of-roundness requirements shown in Table 1 and Table 2 for pipe,tubing, and fittings apply to the average measured diameter. N OTE  5—  Example : In the 1-in. [25 mm] tubing size, if the measuredaverage tubing diameter was 1.123 in. [28.52 mm], then the extrememeasured diameters due to ovality could be 1.129 in. [28.68 mm]maximum and 1.117 in. [28.37 mm] minimum. 6.1.2  Pipe and Tubing :6.1.2.1  Outside Diameter and Wall Thickness —The outsidediameters and wall thicknesses for pipe and tubing shall meetthe requirements for dimension and tolerance given in Table 1when measured in accordance with Test Method D 2122.6.1.2.2  Wall Thickness Range —The wall thickness range forpipe and tubing shall be within 12 % when measured inaccordance with Test Method D 2122.6.1.2.3  Flattening —There shall be no evidence of split-ting, cracking, or breaking when the pipe is tested in accor-dance with 9.2.6.1.2.4  Length —Pipe and tubing supplied in straight lengthsshall have a tolerance on any specified length of + 1  ⁄  2  , −0 in.[+12.5, −0 mm].6.1.3  Socket-Type Fittings :6.1.3.1  Dimensions —Fitting sockets, inside diameters (wa-terways), wall thicknesses, laying lengths, and reducing bush-ing minimums shall meet the requirements for dimension andtolerance given in Table 2, Table 3, and Table 4 when measuredin accordance with Test Method D 2122. The spigot ends of street fittings shall meet the outside diameter and minimumwall requirements of Table 1.6.1.3.2  Alignment  —The maximum angular variation of anysocket opening shall not exceed  1  ⁄  2  ° off the true centerlineaxis.6.1.4  Plastic-to-Metal Transition Fittings :6.1.4.1  Basic Dimensions —Plastic parts of plastic-to-metaltransition fittings shall meet the dimensional requirements of Table 1 and Table 2, where applicable, with the followingexceptions. Such parts shall be exempted from the require-ments for inside diameter (waterway) and wall thicknesstolerance.6.1.4.2  Threads —For all fittings having taper pipe threads,threads shall conform to Specification F 1498 and be gaged inaccordance with 9.5.6.2  Hydrostatic Sustained Pressure :6.2.1  General —Pipe, tubing, and fittings (tested as assem-blies) shall meet the minimum hydrostatic sustained pressurerequirements of both test conditions shown in Table 5 whentested in accordance with 9.2.6.2.2  Pipe and Tubing Quality —Test Condition B shall betermed the primary sustained pressure test for pipe and tubingand shall be used for quality control (see Appendix X3). TestCondition A shall be termed the secondary sustained pressuretest for pipe and tubing and shall be used for periodicperformance qualification. Failure to pass either test is causefor rejection.6.2.3  Fitting Quality —Test Condition A shall be termed theprimary sustained pressure test for fittings and shall be used forquality control (see Appendix X3). Test Condition B shall betermed the secondary sustained pressure test for fittings andshall be used for periodic performance qualification. Failure topass either test is cause for rejection. N OTE  6—Drop weight impact resistance is correlatable with hydrostaticsustained pressure resistance for CPVC 41 components, and may be usefulfor predicting compliance with the sustained pressure requirements of Table 5. Such correlations will necessarily differ with the size, wallthickness, and geometry of individual components. Test Method D 2444using Tup A and Holder A is suggested for nominal diameters of 1 in. [25mm] and above. For smaller components, a guided mandrel type of impacter such as the Gardner Impacter 6 equipped with a  1  ⁄  2  in. [12.7 mm]radius mandrel is suggested. Drop impact is not included in this specifi-cation directly as a quality requirement because of the wide test scatter 6 Available from the Plastics Pipe Institute, 355 Lexington Ave., New York, NY10017.
