Designation:D744609Standard Specification forStructural Insulated Panel(SIP)Adhesives for LaminatingOriented Strand Board(OSB)to Rigid Cellular PolystryeneThermal Insulation Core Materials1This standard is issued under the fixed designation D7446;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 is designed to evaluate adhesivessuitable for the bonding of oriented strand board(OSB)to rigidcellular polystyrene insulation core materials for general struc-ture use.1.2 The requirements of the structural insulated panel(SIP)adhesive are based on the performance of the adhesive asmeasured by:1.2.1 Resistance to shear by compression loading in ambi-ent conditions and after accelerated aging.1.2.2 Resistance to tensile loading in ambient conditionsand after accelerated aging.1.2.3 Resistance to creep(deformation)under static load inambient conditions and after accelerated aging.1.2.4 Tensile and shear strength to polystyrene core materi-als.1.3 The classification of the adhesive formulation is basedon,but not limited to the adhesives industry accepted genericnames,for example:phenol-resorcinol,emulsion polymerisocyanate,one and two-part urethane.The type of adhesiveapplication and curing terminology are also usually includedfor classification purposes such as cold-setting phenolresorcinol,heat-cured phenol resorcinol,and hot melt onecomponent urethane.1.4 Evaluation of adhesive performance at high temperatureconditions,such as during a fire exposure,is beyond the scopeof this specification.1.5 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.6 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.2.Referenced Documents2.1 ASTM Standards:2C273/C273M Test Method for Shear Properties of SandwichCore MaterialsC297/C297M Test Method for Flatwise Tensile Strength ofSandwich ConstructionsC578 Specification for Rigid,Cellular Polystyrene ThermalInsulationD572 Test Method for RubberDeterioration by Heat andOxygenD905 Test Method for Strength Properties of AdhesiveBonds in Shear by Compression LoadingD907 Terminology of AdhesivesD1183 Practices for Resistance of Adhesives to CyclicLaboratory Aging ConditionsD1583 Test Method for Hydrogen Ion Concentration of DryAdhesive FilmsD2294 Test Method for Creep Properties of Adhesives inShear by Tension Loading(Metal-to-Metal)D4300 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 MaterialsD4444 Test Method for Laboratory Standardization andCalibration of Hand-Held Moisture MetersE4 Practices for Force Verification of Testing Machines2.2 Other Standards:PS2 Performance Standard for Wood-Based Structural-UsePanels31This specification is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.70 on ConstructionAdhesives.Current edition approved Sept.1,2009.Published October 2009.DOI:10.1520/D7446-09.2For 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 States1 ISO 17025 General Requirements for the Competence ofTesting and Calibration Laboratories43.Terminology3.1 DefinitionsMany terms in this specification are de-fined in Terminology D907.3.2 Definitions of Terms Specific to This Standard:3.2.1 core material,nlocated between structural insulatedpanel facings;for this specification,consists of rigid cellularpolystyrene thermal insulation,either expanded polystyrene(EPS)or extruded polystyrene(XPS)that conforms to Speci-fication C578.3.2.2 facings,nthe outer layers of a structural insulatedpanel typically consisting of oriented strand board.3.2.3 oriented strand board(OSB),na mat formed panelproduct with oriented layers resulting in directional properties.3.2.3.1 DiscussionOriented strand board is comprised pri-marily of wood strands bonded with exterior adhesive formu-lations under heat and pressure.Design capacities are refer-enced to the primary and secondary structural axis,whichtypically correspond to the manufacturing machine and cross-machine
