Designation:D439622Standard Specification forRigid Poly(Vinyl Chloride)(PVC)and Chlorinated Poly(VinylChloride)(CPVC)Compounds for Plastic Pipe and FittingsUsed in Nonpressure Applications1This standard is issued under the fixed designation D4396;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 reapproval.1.Scope*1.1 This specification covers the classification and identifi-cation of rigid plastic compounds intended for use in makingnonpressure piping products composed of(1)poly(vinyl chlo-ride)polymer,(2)chlorinated poly(vinyl chloride)polymer,or(3)vinyl chloride copolymers,and the necessary compoundingredients.Compounding ingredients consist of lubricants;stabilizers;non-poly(vinyl chloride)resin modifiers;colorantsor pigments,or both;fibrous or nonfibrous reinforcements;orfillers.1.2 The requirements in this specification are intended forthe quality control of compounds used to manufacture pipe orfittings intended for nonpressure use.Specific properties arenot directly applicable to finished products.When specified ina product or application standard,the series of classificationproperties in this standard form a basis for a material specifi-cation.See the applicableASTM standards or requirements forfinished products.1.3 In special cases,specific compounds for unusual pipingapplications that require consideration of other properties notcovered in this specification,such as service temperature,sagresistance,special chemical resistance,weather resistance,bending forces,and electrical properties,shall be considered.1.4 Rigid PVC-type compounds for building applicationsother than piping are covered in Specification D4216.1.5 Rigid PVC compounds for general purpose extrusion,molding,fitting,and pipe are covered in Specification D1784.1.6 The rate of burning test,Test Method D635,is used inthis specification as a test for identification of certain propertiesof the compound.1.7 It is acceptable for rigid PVC and CPVC recycle plasticsmeeting the requirements of this specification to be used insome applications.Refer to the specific requirements in theMaterial and Manufacture section of the applicable productstandard.1.8 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.1.9 The following safety hazards caveat pertains only to thetest methods portion,Section 10,of this specification:Thisstandard does 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,health,andenvironmental practices and determine the applicability ofregulatory limitations prior to use.NOTE1There is no known ISO equivalent to this standard.1.10 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D256 Test Methods for Determining the Izod PendulumImpact Resistance of PlasticsD618 Practice for Conditioning Plastics for TestingD635 Test Method for Rate of Burning and/or Extent andTime of Burning of Plastics in a Horizontal PositionD638 Test Method for Tensile Properties of PlasticsD648 Test Method for Deflection Temperature of PlasticsUnder Flexural Load in the Edgewise PositionD883 Terminology Relating to PlasticsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD1784 Classification System and Basis for Specification for1This specification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.15 on ThermoplasticMaterials.Current edition approved Sept.1,2022.Published September 2022.Originallyapproved in 1984.Last previous edition approved in 2015 as D4396 15.DOI:10.1520/D4396-22.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1Rigid Poly(Vinyl Chloride)(PVC)Compounds and Chlo-rinated Poly(Vinyl Chloride)(CPVC)Compound
