Designation:D767214Standard Specification forEvaluating Structural Capacities of Rim Board Products andAssemblies1This standard is issued under the fixed designation D7672;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.INTRODUCTIONRim board assemblies are an engineered component within light-frame wood platform construction.Rim board assemblies serve in multiple structural capacities,including:providing floor closure anddiaphragm attachment,transferring vertical and in-plane lateral loads,restricting out-of-plane rotationand lateral translation at the ends of the floor joists,providing deck ledger attachment,and spanningwall openings as a header material.Rim board products,which serve a principal role as a componentintegrated within a rim board assembly,can vary by wood species,size,shape,and type.Rim boardproducts and assemblies require evaluation of their mechanical properties,physical properties,andtheir response to end use environments.Procedures established in this Specification provide a meansto test rim board products and assemblies,to judge their acceptability,and to establish allowabledesign capacities.1.Scope1.1 This specification provides procedures for testing andestablishing the structural capacities of proprietary rim boardproducts and assemblies for use in light-frame wood construc-tion using I-joist or structural composite lumber joist framing.This specification does not apply to commodity rim boardproducts.1.2 This specification was developed in light of currentlymanufactured panel,structural composite lumber,and pre-fabricated I-joist rim board products as defined in 3.2.Mate-rials that do not conform to the definitions of 3.2 are beyondthe scope of this specification.1.3 Fire safety,sound transmission,building envelopeperformance,and cutting/notching attributes of rim boardproducts and assemblies fall outside the scope of this specifi-cation.1.4 This specification primarily considers end use in dryservice conditions,such as most protected framing members,where the equilibrium moisture content for solid-sawn lumberis less than 16%.1.5 This specification provides methods to establish“allow-able stress”design resistances for use with the National DesignSpecification for Wood Construction(NDS).Derivation ofdesign resistances from the test data in accordance with“loadand resistance factor design”or“limit states design”arebeyond the scope of this specification.1.6 Quality control requirements are outside the scope ofthis Specification.1.7 The performance of a rim board product will be affectedby the constituent wood species,geometry,adhesive,andproduction parameters.Therefore,rim board products pro-duced by each individual manufacturer shall be evaluated todetermine their product properties,regardless of the similarityin characteristics to products produced by other manufacturers.1.8 Where a manufacturer produces product in more thanone facility,each production facility shall be evaluated inde-pendently.For additional production facilities,any revisions tothe full qualification program in accordance with this specifi-cation shall be approved by an accredited,independent quali-fying agency.1.9 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.10 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.1This specification is under the jurisdiction of ASTM Committee D07 on Woodand is the direct responsibility of Subcommittee D07.05 on Wood Assemblies.Current edition approved Oct.1,2014.Published November 2014.Originallyapproved in 2011.Last previous edition approved in 2013 as D767213.DOI:10.1520/D767214.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.Referenced Documents2.1 ASTM Standards:2D9 Terminology Relating to Wood and Wood-Based Prod-uctsD198 Test Methods of Static Tests of Lumber in StructuralSizesD1037 Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel MaterialsD2395 Test Methods for Density and Specific Gravity(Rela-tive Density)of Wood and Wood-Based MaterialsD2915 Practice for Sampling and Data-Analysis for Struc-tural Wood and Wood-Based ProductsD4442 Test Methods for Direct Moisture Content Measure-ment of Wood and Wood-Based MaterialsD4761 Test Methods for Mechanical Properties of Lumberand Wood-Base Structural MaterialD5055 Specification for Establishing and Monitoring Struc-
