1、Designation: D1785 15 An American National StandardStandard Specification forPoly(Vinyl Chloride) (PVC) Plastic Pipe, Schedules 40, 80,and 1201This standard is issued under the fixed designation D1785; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1
3、This specification covers poly(vinyl chloride) (PVC)pipe made in Schedule 40, 80, and 120 sizes and pressure-ratedfor water (see Appendix X1). Included are criteria for classi-fying PVC plastic pipe materials and PVC plastic pipe, asystem of nomenclature for PVC plastic pipe, and requirementsand tes
4、t methods for materials, workmanship, dimensions,sustained pressure, burst pressure, flattening, and extrusionquality. 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 compatibl
5、e 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 procedu
6、res prior to pneumatic testing.NOTE 1Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safteyhazards should a system fail for any reason.NOTE 2This standard specifies dimensional, performance and testrequirements for plumbing and fluid
7、 handling applications only. It doesnot include provisions for the use of these products for venting ofcombustion gases. UL 1738 is a standard that does include specific testingand marking requirements for flue gas venting products, including PVC.1.3 The text of this specification references notes,
8、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 inch-pound units are to be regardedas standard. The values given in parentheses are mathe
9、maticalconversions to SI units that are provided for information onlyand are not considered standard.1.5 The following safety hazards caveat pertains only to thetest methods portion, Section 8, of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associa
10、ted 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 9.NOTE 3CPVC plastic pipes, Schedules 40 and 80, whic
11、h wereformerly included in this specification, are now covered by SpecificationF441/F441M.NOTE 4The sustained and burst pressure test requirements, and thepressure ratings in the Appendix X1, are calculated from stress valuesobtained from tests made on pipe 4 in. (100 mm) and smaller. However,tests
12、conducted on pipe as large as 24-in. (600-mm) 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.
