Designation:D557295(Reapproved 2012)Standard Specification forAdhesives Used for Finger Joints in Nonstructural LumberProducts1This standard is issued under the fixed designation D5572;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 specification establishes performance levels foradhesives to be used in finger joints in nonstructural bonded-lumber products.Such products include,but are not limited to,interior and exterior mouldings,window and door componentsor parts,and bonded-lumber panels.Adhesives that meet therequirements of the various performance classes are consideredcapable of providing an adequate bond for use under theconditions described for the class.This specification is to beused to evaluate adhesives as well as the adhesive bonds in thefinger joints.See Section 5,Significance and Use,for limita-tions when using this specification to evaluate industriallymanufactured finger joints.NOTE1This specification supersedes the finger-joint portion of the1990 edition of Specification D3110.1.2 The following index is provided as a guide to the testmethods in this specification:SectionApparatus6Equipment,Material,and Preparation of Assemblies and Specimens7Conditioning for Factory-Manufactured Assemblies,Laboratory-MadeAssemblies,and Test Specimens8Testing in Flexure9Testing in Tension10Exposure Conditions and Treatments111.Dry Use Tests:Dry,3-cycle Soak,Elevated Temperature,and Temperature-Humidity11.12.Wet Use Tests:Dry,Boil,Elevated Temperature,andVacuum-Pressure11.2NOTE2The conditioning needed for various stages in the preparationof both types of specimens and for the exposure tests are given.NOTE3Specific guidelines for specimen size,exposure conditions,testing,calculation,and reporting are given for flexure specimens inSections 9 and 11,and for tension specimens in Sections 10 and 11.1.3 For the definitions of dry use and wet use,see 3.2.1.1and 3.2.1.2.1.4 The values stated in inch-pound units are to be regardedas standard.The SI units given in parentheses are for informa-tion only.1.5 The following precautionary caveat pertains only to theapparatus and test methods portions,Sections 6 11 of thisspecification:This standard does not purport to address all ofthe safety 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:2D143 Test Methods for Small Clear Specimens of TimberD907 Terminology of AdhesivesD2016 Methods of Test for Moisture Content of Wood(Withdrawn 1987)3D3110 Specification for Adhesives Used in Laminate Jointsfor Nonstructural Glued Lumber Products(Withdrawn1996)3D4688 Test Method for Evaluating Structural Adhesives forFinger Jointing LumberD5266 Practice for Estimating the Percentage of WoodFailure in Adhesive Bonded JointsE4 Practices for Force Verification of Testing MachinesE6 Terminology Relating to Methods of Mechanical TestingE41 Terminology Relating To ConditioningE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Terminology3.1 Definitions:3.1.1 Many terms in this specification are defined in Termi-nology D907 and Terminology E41.3.1.2 bond,nthe union of materials by adhesives.3.1.3 finger joint,na joint formed by bonding two precutmembers shaped like fingers.(See Figs.1 and 2.)1This specification is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.30 on WoodAdhesives.Current edition approved Oct.1,2012.Published October 2012.Originallyapproved in 1994.Last previous edition approved in 2005 as D5572 95(2005).DOI:10.1520/D5572-95R12.2For 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 3.2 Definitions of Terms Specific to This Standard:3.2.1nonstructural adhesive:3.2.1.1 dry use nonstructural adhesive,nan adhesivecapable of producing sufficient strength and durability to makethe bonded lumber product serviceable in nonstructural use,under conditions in which the equilibrium moisture content(EMC)of the wood does not exceed 16%.3.2.1.2 wet use nonstructural adhesive,nan adhesivecapable of producing sufficient strength and durability to makethe bonded lumber product serviceable
