2、ision.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 specification covers poly(vinyl chloride
3、)(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 test methods for materials,workmanship,dimensions,susta
4、ined 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 compatible with the piping materials.Due toinherent hazards associat

10、blish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.A specific precautionary statement is givenin Note 9.NOTE3CPVC plastic pipes,Schedules 40 and 80,which wereformerly included in this specification,are now covered by SpecificationF441
11、/F441M.NOTE4The 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 conducted on pipe as large as 24-in.(600-mm)diameter have shownthese stress values to be
12、valid for larger diameter PVC pipe.NOTE5PVC pipe made to this specification is often belled for use asline pipe.For details of the solvent cement bell,see Specification D2672and for details of belled elastomeric joints,see Specifications D3139 andD3212.2.Referenced Documents2.1 ASTM Standards:2D618
