Standard Specification for (PVC) Plastic Pipe, …

1 Provided by : Designation: D1785 12An American National StandardStandard Specification forPoly( vinyl chloride ) (PVC) Plastic pipe , Schedules 40, 80,and 1201 This Standard is issued under the fixed designation D1785; the number immediately following the designation indicates the year oforiginal adoption or, in the 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 Standard has been approved for use by agencies of the Department of Scope* This Specification covers poly ( vinyl chloride ) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-ratedfor water (seeAppendix X1).

2 Included are criteria for classi-fying PVCplastic pipe materials and PVC Plastic pipe , asystem of nomenclature for PVC Plastic pipe , and requirementsand test methods for materials, workmanship, dimensions,sustained pressure, burst pressure, flattening, and extrusionquality. Methods of marking are also 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 with specific product/component manufacturers fortheir specific testing procedures prior to pneumatic Pressurized (compressed)

3 Air or other compressed gasescontain large amounts of stored energy which present serious safteyhazards should a system fail for any This Standard specifies dimensional, performance and testrequirements for plumbing and fluid handling applications, but does notaddress venting of combustion 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 The values stated in inch-pound units are to be regardedas Standard .

4 The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered The following safety hazards caveat pertains only to thetest methods portion, Section8, of this Specification :Thisstandarddoes 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 healthpractices and determine the applicability of regulatory limita-tions prior to specific precautionary statement is giveninNote CPVC Plastic pipes, Schedules 40 and 80, which wereformerly included in this Specification , are now covered by SpecificationF441 The sustained and burst pressure test requirements, and thepressure ratings in theAppendix X1.

5 Are calculated from stress valuesobtainedfromtests made on pipe 4 in. (100 mm) and smaller. However,tests conducted on pipe as large as 24-in. (600-mm) diameter have shownthese stress values to be valid for larger diameter PVC PVC pipe made to this Specification is often belled for use asline pipe .
