Designation:D349819aStandard Specification forAdhesives for Field-Gluing Wood Structural Panels(Plywood or Oriented Strand Board)to Wood Based FloorSystem Framing1This standard is issued under the fixed designation D3498;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 covers minimum performance stan-dards and test requirements for gap-filling construction adhe-sives for bonding wood structural panels consisting of plywoodor oriented strand board(OSB)to wood based floor systemframing,particularly dimension lumber or wood I-joists,at theconstruction site.1.2 This specification provides a basis for ensuring thequality of the adhesives and is not intended as an applicationspecification.1.3 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.1.4 The following precautionary caveat pertains only to thetest method portion,Section 11,of this specification:Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety,health,andenvironmental practices and determine the applicability ofregulatory limitations prior to use.1.5 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:2D572 Test Method for RubberDeterioration by Heat andOxygenD905 Test Method for Strength Properties of AdhesiveBonds in Shear by Compression LoadingD907 Terminology of AdhesivesD4300 Test Methods for Ability of Adhesive Films toSupport or Resist the Growth of FungiD4442 Test Methods for Direct Moisture Content Measure-ment of Wood and Wood-Based MaterialsD4783 Test Methods for Resistance of Adhesive Prepara-tions in Container to Attack by Bacteria,Yeast,and FungiE4 Practices for Force Verification of Testing MachinesE177 Practice for Use of the Terms Precision and Bias inASTM Test Methods2.2 Voluntary Product Standards:3PS1 Structural PlywoodPS2 Performance Standard for Wood-Based Structural-UsePanels3.Terminology3.1 Definitions:3.1.1 Many terms in this specification are defined in Termi-nology D907.3.1.2 gap class,na classification used to indicate whethera product has been qualified using a18in.(1.59 mm)gapcondition.3.1.3 gap-filling adhesive,nan adhesive capable of form-ing and maintaining a bond between surfaces that are notclose-fitting.3.1.3.1 DiscussionClose-fitting is relative to a given ma-terial and industry;for example,standards in constructiondiffer from standards in electronics.Some adhesives will bondby bridging without completely filling the gap;others by fillingthe gap completely.3.1.4 open assembly time,nthe time interval betweenapplying adhesive on the substrates and closing them togetherbefore bonding.1This specification is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.70 on ConstructionAdhesives.Current edition approved June 1,2019.Published June 2019.Originallyapproved in 1976.Last previous edition approved in 2019 as D3498 19.DOI:10.1520/D3498-19a.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 National Institute of Standards and Technology(NIST),100Bureau Dr.,Stop 1070,Gaithersburg,MD 20899-1070,http:/www.nist.gov.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 3.1.5 oriented strand board(OSB),na mat formed panelproduct with oriented layers resulting in directional properties.3.1.6 panel type,na classification used to indicate whethera product has been qualified using OSB and/or plywood panels.3.1.7 plywood,na conventional all-veneer panel withalternate layers of veneer which are orientated perpendicular toeach other.3.1.8 wood-I joist,na structural member manufacturedusing sawn or structural composite lumber flanges and struc-tural panel webs,bonded t
