Designation:D322205(Reapproved 2015)Standard Specification forUnmodified Poly(Vinylidene Fluoride)(PVDF)MoldingExtrusion and Coating Materials1This standard is issued under the fixed designation D3222;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers melt processable molding andextrusion materials,as well as coating materials of poly(vi-nylidene fluoride)fluoroplastic,commonly abbreviated PVDF(or PVF2in scientific literature).This specification coversthermoplastic resin materials supplied in pellet or powderform.1.2 This specification applies only to the virgin homopoly-mer prepared from vinylidene fluoride,not copolymers,reinforced,filled grades or special grades with additives ortreatments for modification of attributes.1.3 The tests involved are intended to provide informationfor specification of unmodified PVDF homopolymer resins.Itis not the purpose of this specification to provide engineeringdata for design purposes.1.4 PVDF fluoroplastics melt between 156 and 180C(312and 356F)and are thermally stable up to about 370C(698F).(WarningEvolution of corrosive and toxic hydrogen fluo-ride can occur under certain conditions.)1.5 The values stated in SI units,as detailed in IEEE/ASTMS-10,are to be regarded as the standard.The values given inparentheses are for information only.NOTE1PVDF exhibits polymorphism.2The type and extent ofcrystalline structure varies with the thermomechanical history of thesample.Specimens prepared by techniques different than prescribed inthis specification can have properties that vary from the values specified.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.Specific precau-tionary statements are given in Section 10.NOTE2There is no equivalent ISO standard for this specification.Information in this specification is technically equivalent to relatedinformation in ISO 12086-1 and ISO 12086-2.2.Referenced Documents2.1 ASTM Standards:3D149 Test Method for Dielectric Breakdown Voltage andDielectric Strength of Solid Electrical Insulating Materialsat Commercial Power FrequenciesD150 Test Methods for AC Loss Characteristics and Permit-tivity(Dielectric Constant)of Solid Electrical InsulationD256 Test Methods for Determining the Izod PendulumImpact Resistance of PlasticsD257 Test Methods for DC Resistance or Conductance ofInsulating MaterialsD542 Test Method for Index of Refraction of TransparentOrganic PlasticsD618 Practice for Conditioning Plastics for TestingD638 Test Method for Tensile Properties of PlasticsD790 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastics and Electrical Insulating Materi-alsD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD883 Terminology Relating to PlasticsD1238 Test Method for Melt Flow Rates of Thermoplasticsby Extrusion PlastometerD2863 Test Method for Measuring the Minimum OxygenConcentration to Support Candle-Like Combustion ofPlastics(Oxygen Index)D3418 Test Method for Transition Temperatures and En-thalpies of Fusion and Crystallization of Polymers byDifferential Scanning CalorimetryD3835 Test Method for Determination of Properties ofPolymeric Materials by Means of a Capillary RheometerD3892 Practice for Packaging/Packing of PlasticsIEEE/ASTM S-10 Use of the International System of Units1This specification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.15 on ThermoplasticMaterials.Current edition approved May 1,2015.Published June 2015.Originallyapproved in 1973.Last previous edition approved in 2010 as D3222-05(2010).DOI:10.1520/D3222-05R15.2Lovinger,A.J.,“Poly(Vinylidene Fluoride)”Developments in CrystallinePolymers,Vol 1,Chapter 5,D.C.Bassett,Ed.,Applied Science,London,1982.3For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1(SI):The Modern Metric System2.2 IEC and ISO Standards:ISO 12086-1PlasticsFluoropolymer Dispersion andMoulding and Extrusion MaterialsPart 1:Designationand Basis for Specification4ISO 12086-2PlasticsFluoropolymer Dispersion andMolding and Extrusion MaterialsPart 2:Preparation ofTest Specimens and Determination of Propertie
