Designation:D703111Standard 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 and health practices and determine the applica-bility of regulatory limitations prior to use.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 and PlywoodD1413 Test Method for Wood Preservatives by LaboratorySoil-Block CulturesD1554 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Ignition Temperatureof PlasticsD2017 Test Method ofAccelerated Laboratory Test of Natu-ral Decay Resistance of Woods(Withdrawn 2014)3D2047 Test Method for Static Coefficient of Friction ofPolish-Coated Flooring Surfaces as Measured by theJames MachineD2394 Test Methods for Simulated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-Base 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 Wood andOther Cellulosic Materials 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 MaterialsD4495 Test Method for Impact Resistance of Poly(VinylChloride)(PVC)Rigid Profiles by Means of a FallingWeightD4761 Test Methods for Mechanical Properties of Lumberand Wood-Base Structural MaterialD5379/D5379M Test Method for Shear Properties of Com-posite Materials by the V-Notched Beam Method1This 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 May 1,2011.Published June 2011.Originallyapproved in 2004.Last previous edition approved in 2004 as D7031 04.DOI:10.1520/D7031-11.2For 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 States1 D5456 Specification for Evaluation of Structural CompositeLumber ProductsD5764 Test Method for Evaluating Dowel-Bearing Strengthof Wood and Wood-Based ProductsD6109 Test Methods for Flexural Properties of Unreinforcedand Reinforced Plastic Lumber and Related ProductsD6341 Test Method for Determination of the Linear Coef-ficient of Thermal Expansion of Plastic Lumber andPlastic Lumber Shapes Between 30 and 140F(34.4and 60C)D6662 Specification for Polyolefin-Based Plastic LumberDecking BoardsE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE108 Test Methods for Fire Tests of Roof CoveringsE661 Test Method for Performance of Wood and Wood-Base
