Designation:D349803(Reapproved 2011)Standard Specification forAdhesives for Field-Gluing Plywood to Lumber Framing forFloor Systems1This 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 plywood to lumber framing,particularlyfloor joists,at the construction 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 and healthpractices and determine the applicability of regulatory limita-tions prior to use.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in Shear by Compression LoadingD907 Terminology of AdhesivesD2016 Methods of Test for Moisture Content of Wood(Withdrawn 1987)3D4300 Test Methods for Ability of Adhesive Films toSupport or Resist the Growth of FungiD4783 Test Methods for Resistance of Adhesive Prepara-tions in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 Methods3.Terminology3.1 Definitions:3.1.1 Many terms in this specification are defined in Termi-nology D907.3.1.2 gap-filling adhesive,nan adhesive capable of form-ing and maintaining a bond between surfaces that are notclose-fitting.3.1.2.1 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.3.1.3 open assembly time,nthe time interval betweenapplying adhesive on the subtrates and closing them togetherbefore bonding.4.Significance and Use4.1 This specification establishes test methods and perfor-mance requirements for adhesives bonding plywood to woodframing members.4.2 This specification provides a basis for ensuring thequality of the adhesives.4.3 The tests provide shear strength performance data whenthe substrates are conditioned to simulate various conditionsthat may occur during sub-floor adhesive application andcuring.4.4 The tests are suitable for product performance certifica-tion and quality control programs,and can be useful to thegeneral public,adhesive manufacturers,distributors,specifiers,architects,contractors,testing laboratories and other businessesand professionals.4.5 The results do not include all possible conditions,whichmay occur during final assembly,but indicate a set of perfor-mance characteristics for laboratory controlled bonding vari-ables.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 Jan.1,2011.Published January 2011.Originallyapproved in 1976.Last previous edition approved in 2003 as D3498 03.DOI:10.1520/D3498-03R11.2For 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 5.Ordering Information5.1 The adhesive may be furnished by the manufacturer inany suitable form agreeable to the purchaser.6.Materials6.1 The adhesive shall be a gap-filling construction adhesivethat sets at temperatures as low as 40F(4.4C).6.2 The adhesive shall not support mold or bacterial growth.If amylaceous or protein fillers and extenders are used in theadhesive formulation,the adhesive must not only pass theperformance requirements of this specification,but in addition,possess sufficient anti-fungal properties to inhibit the growth ofselected fungal species when tested in accordance with TestMethods D4300 and selected bacterial species in accordancewith Test Methods D4783.The adhesive manufacturer shallnotif
