1、Designation: D2466 17 An American National StandardStandard Specification forPoly(Vinyl Chloride) (PVC) Plastic Pipe Fittings, Schedule401This standard is issued under the fixed designation D2466; 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 () 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 This

3、specification covers poly(vinyl chloride) (PVC)Schedule 40 pipe fittings. Included are requirements formaterials, workmanship, dimensions, and burst pressure.NOTE 1Socket-type CPVC plastic pipe fittings, Schedule 40, whichwere formerly included in this standard, are now covered by SpecificationF438.

4、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, somema

5、nufacturers 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

19、 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 normallymolded. In-line fittings, such as couplings, bushings, caps,nipples, etc., shall be molded or machin

20、ed 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 Specification D1784. Theseare PVC 12454, 12454, 13354, 11443, and 14333.5.2 CompoundThe PVC plasti

21、c compound shall meet therequirements of PVC 12454, 12454, 11443, or 14333, asdescribed in Specification D1784.NOTE 3Mechanical strength, heat resistance, flammability, andchemical resistance requirements are covered in Specification D1784.5.3 Rework MaterialThe manufacturers shall use onlytheir own

35、. TheD2466 172pressure shall be applied at a uniform rate such that theminimum allowable burst pressure is attained in 60 to 70 s.NOTE 5Provided the minimum burst pressure is met or exceededbetween 60 and 70 s, the time-to-failure may exceed 70 s.9. Retest and Rejection9.1 If the results of any test

36、(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 not be lowered,changed, or modified, nor shall specification limits be changed.If upon retest, failure occur
