Designation:D110197a(Reapproved 2018)Standard Test Methods forIntegrity of Adhesive Joints in Structural Laminated WoodProducts for Exterior Use1This standard is issued under the fixed designation D1101;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.INTRODUCTIONThe integrity of adhesive joints for structural laminated wood members,such as laminated archesand beams,should be at least equal to that of the wood.Because initial strength tests generally are notan adequate measure of integrity of adhesive joints under severe service conditions,a test thatsimulates the effects of exterior exposure has been devised to evaluate adhesive joints in structurallaminated wood members intended for this type of service.1.Scope1.1 These test methods cover an accelerated means ofmeasuring the resistance to delamination of structural lami-nated wood members intended for exterior service.1.2 These test methods are not intended as substitutes orreplacements for the more severe test of resistance to delami-nation in Specification D2559.1.3 Two test methods are included.Choice of test methoddepends on purpose of the test and available time to complete.1.3.1 Test Method AThis test requires 3 days to completeand is a method for determining the suitability of adhesives andmanufacturing techniques and equipment for production ofjoints adequate for exterior service.1.3.2 Test Method BThis test requires approximately 1212h.(If excessive delamination occurs,the cycle is repeated).Itis a quality-control type test for examining adhesive jointquality.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 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.1.6 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:2D907 Terminology of AdhesivesD2559 Specification for Adhesives for Bonded StructuralWood Products for Use Under Exterior Exposure Condi-tions2.2 Other Standards:3ANSI A190.1 American Nation Standard for WoodProductsStructural Glued Laminated Timber3.Terminology3.1 DefinitionsMany terms in these test methods aredefined in Terminology D907.3.1.1 glulam,nsynonym for structural-glued-laminatedtimber.3.1.2 structural-glued-laminated timber,nan engineeredstress-rated product of a timber laminating plant comprisingassemblies of specially selected and prepared wood lamina-tions securely bonded together with adhesives,with the fol-lowing characteristics:(1)the grain of all laminations isapproximately parallel longitudinally;and(2)the laminationsmay be comprised of pieces end-joined to form any length,ofpieces placed or glued edge-to-edge to make wider ones or of1These test methods are under the jurisdiction of ASTM Committee D14 onAdhesives and are the direct responsibility of Subcommittee D14.30 on WoodAdhesives.Current edition approved Aug.1,2018.Published August 2018.Originallyapproved in 1997.Last previous edition approve in 2013 as D1101 97a(2013).DOI:10.1520/D1101-97AR18.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.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 pieces bent to curved form during gluing.(Synonym glulam)ANSI A190.1.American National Standard for Wood Prod-uctsStructural Laminated.3.2 Definitions of Terms Specific to This Standard:3.2.1 laminated wood,nthe fabricated product resultingfrom the bonding of two or more laminations,with eachlamination made from one or more pieces bonded eitherlengthwise,edgewise,or both,and all with the direction of thegrain essentially parallel,to form a larger piece such
