Designation:D703111(Reapproved 2019)Standard Guide forEvaluating Mechanical and Physical Properties of Wood-Plastic Composite Products1This standard is issued under the fixed designation D7031;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.Scope1.1 This guide covers test methods appropriate for evaluat-ing a wide range of performance properties for wood-plasticcomposite(WPC)products.It was developed from evaluationsof both experimental and currently manufactured products,andis not intended to suggest that all the tests listed are necessaryor appropriate for each application of a WPC.The user mustdetermine which test methods apply to the particular applica-tion being evaluated(see Appendix X1).1.2 Details of manufacturing processes may be proprietaryand are beyond the scope of this guide.1.3 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 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:2C1308 Test Method forAccelerated Leach Test for DiffusiveReleases from Solidified Waste and a Computer Programto Model Diffusive,Fractional Leaching from CylindricalWaste FormsD9 Terminology Relating to Wood and Wood-Based Prod-uctsD143 Test Methods for Small Clear Specimens of TimberD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD883 Terminology Relating to PlasticsD1037 Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel MaterialsD1038 Terminology Relating to Veneer,Plywood,and WoodStructural PanelsD1413 Test Method for Wood Preservatives by LaboratorySoil-Block Cultures(Withdrawn 2016)3D1554 Terminology Relating to Wood-Base Fiber and Par-ticle Panel MaterialsD1761 Test Methods for Mechanical Fasteners in WoodD1929 Test Method for Determining Ignition Temperatureof PlasticsD2017 Test Method ofAccelerated Laboratory Test of Natu-ral Decay Resistance of Woods(Withdrawn 2014)3D2047 Test Method for Static Coefficient of Friction ofPolish-Coated Flooring Surfaces as Measured by theJames MachineD2394 Test Methods for Simulated Service Testing of Woodand Wood-Based Finish FlooringD2395 Test Methods for Density and Specific Gravity(Rela-tive Density)of Wood and Wood-Based MaterialsD2481 Test Method for Accelerated Evaluation of WoodPreservatives for Marine Services by Means of Small SizeSpecimens(Withdrawn 2014)3D2565 Practice for Xenon-Arc Exposure of Plastics In-tended for Outdoor ApplicationsD2915 Practice for Sampling and Data-Analysis for Struc-tural Wood and Wood-Based ProductsD3345 Test Method for Laboratory Evaluation of SolidWood for Resistance to TermitesD4000 Classification System for Specifying Plastic Materi-alsD4060 Test Method for Abrasion Resistance of OrganicCoatings by the Taber AbraserD4092 Terminology for Plastics:Dynamic MechanicalPropertiesD4442 Test Methods for Direct Moisture Content Measure-ment of Wood and Wood-Based Materials1This guide is under the jurisdiction of ASTM Committee D07 on Wood and isthe direct responsibility of Subcommittee D07.02 on Lumber and Engineered WoodProducts.Current edition approved July 15,2019.Published August 2019.Originallyapproved in 2004.Last previous edition approved in 2011 as D7031 11.DOI:10.1520/D7031-11R19.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright 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.1 D4495 Test Method for Impact Resistance of Poly(VinylChloride)(PVC)Rigid Profiles by Means of a FallingWeightD4761 Test Methods for Mechanical Properties of Lumberand Wood-Based Structural MaterialsD5379/D5379M Test Method for Shear Properties of Com-posite Materials by the V-N
