1、Designation: D 2241 05An American National StandardStandard Specification forPoly(Vinyl Chloride) (PVC) Pressure-Rated Pipe (SDRSeries)1This standard is issued under the fixed designation D 2241; the number immediately following the designation indicates the year oforiginal adoption or, in the case
2、of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript 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.1. Scope1.1 This specif
3、ication covers poly(vinyl chloride) (PVC)pipe made in standard thermoplastic pipe dimension ratios andpressure rated for water (see appendix). Included are criteriafor classifying PVC plastic pipe materials and PVC plasticpipe, a system of nomenclature for PVC plastic pipe, andrequirements and test
4、methods for materials, workmanship,dimensions, sustained pressure, burst pressure, flattening, andextrusion quality. Methods of marking are also given.1.2 The products covered by this specification are intendedfor use with the distribution of pressurized liquids only, whichare chemically compatible
5、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 procedur
6、es prior to pneumatic testing.NOTE 1Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safetyhazards should a system fail for any reason.NOTE 2This standard specifies dimensional, performance and testrequirements for plumbing and fluid
7、handling applications, but does notaddress venting of combustion gases.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 spec
8、ification.1.4 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.5 The following safety hazards caveat pertains only to thetest methods portion, Section 8, of this specification: Thisstandard does not purport to address
9、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 healthpractices and determine the applicability of regulatory limita-tions prior to use. A specific precautionary statement is givenin Note 7.NOTE 3CPV
10、C plastic pipe (SDR-PR), which was formerly includedin this specification, is now covered by Specification F 442/F 442M.NOTE 4The sustained and burst pressure test requirements, and thepressure ratings in the appendix, are calculated from stress values obtainedfrom tests made on pipe 4 in. (100 mm)
11、and smaller. However, testsconducted on pipe as large as 24 in. (600 mm) in diameter have shownthese stress values to be valid for larger diameter PVC pipe.NOTE 5PVC pipe made to this specification is often belled for use asline pipe. For details of the solvent cement bell, see Specification D 2672a

22、 dimension ratio, hydro-static design stress, and pressure ratingThe following ex-pression, commonly known as the ISO equation,4is used inthis specification to relate standard dimension ratio, hydrostaticdesign stress, and pressure rating:2S/P 5 R 2 1 or 2 S/P 5 D0/t! 2 1 (1)where:S = hydrostatic de
23、sign stress, psi (or MPa),P = pressure rating, psi (or MPa),D0= average outside diameter, in. (or mm),t = minimum wall thickness, in. (or mm), andR = standard thermoplastic pipe dimension ratio (D0/t forPVC pipe), also known as SDR.3.2.4 standard thermoplastic pipe dimension ratio (SDR)the ratio of
24、pipe diameter to wall thickness. For PVC pipe it iscalculated by dividing the average outside diameter of the pipein inches or millimetres by the minimum wall thickness ininches or millimetres. If the wall thickness calculated by thisformula is less than 0.060 in. (1.52 mm), it shall be arbitrarilyi
