Designation:D600404(Reapproved 2011)Standard Test Method forDetermining Adhesive Shear Strength of Carpet Adhesives1This standard is issued under the fixed designation D6004;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 test method describes a procedure to measure shearstrength development for adhesives used to bond carpet adhe-sives to selected underlayments.1.2 This test method provides a quantitative means ofmeasuring and recording shear strength of the adhesive when itis applied to the desired underlayment.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 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:2D618 Practice for Conditioning Plastics for TestingD907 Terminology of AdhesivesE4 Practices for Force Verification of Testing MachinesE177 Practice for Use of the Terms Precision and Bias inASTM Test Methods2.2Voluntary Product Standards3PS1 Construction and Industrial PlywoodPS2 Structural Use Panels3.Terminology3.1 DefinitionsMany of the terms in this test method aredefined in Terminology D907.4.Significance and Use4.1 In selecting or developing a carpet adhesive,it is criticalto have knowledge regarding how well the adhesive will bondto the desired underlayment.Shear loading simulates a com-mon failure mode.4.2 The test method determines the failure shear load for thetest adhesive and specific underlayment combination.5.Apparatus5.1 Applicator trowel,with a notch pattern of18in.(3.2mm)wide,332in.(2.4 mm)deep,18in.(3.2 mm)flat.5.2 Three 10-lb(4.54-kg)weight equivalents.5.3 Three 2 3-in.(51 mm 76 mm)sections of underlay-ment for dead weight distribution.5.4 Convection Oven,capable of maintaining a temperatureof 122 6 2F(50 6 1C).5.5 Calibrated Universal Testing Machine,capable of acontrolled application of force with a force measurementaccuracy of 6 1%when calibrated in compliance withPractices E4 requirements.6.Materials6.1 AdhesiveAny appropriate adhesive for carpet installa-tion.6.2 Duck clothnatural,untreated,#10,14.73 oz.6.3 UnderlaymentCommon wood-based products such asPS2 grade mark stamped oriented strand board underlaymentor PS1 grade mark stamped plywood underlayment.Otherproducts,recommended by the adhesive manufacturer mayalso be used.7.Conditioning7.1 Condition the duck cloth,underlayment and adhesive tobe tested for 24 h at 73 6 3F(23 6 2C)and 50%6 5%relative humidity prior to testing.8.Sample Preparation8.1 Cut the duck cloth into three 2 6-in.(51 127-mm)pieces.8.2 Cut one section of underlayment into a 16 5-in.(406 127-mm)section.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.70 on ConstructionAdhesivesCurrent edition approved Jan.1,2011.Published January 2011.Originallyapproved in 1996.Last previous edition approved in 2004 as D6004-04.DOI:10.1520/D6004-04R11.2For 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 Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/dodssp.daps.dla.mil.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 9.Procedure9.1 Hold the trowel at a 45 angle and spread sufficientadhesive to cover the bonding areas.9.2 Wait 10 min and place three pieces of duck clothperpendicular to the trowel pattern,each covering a 6-in.2or3 2-in.(38.7 cm2or 51 76 mm)area of the adhesive(Fig.1).9.3 Place a 2 3-in.(51 76 mm)underlayment section ontop of each duck cloth piece for dead weight distribution(Fig.2).9.4 Place a 10-lb weight on each 2 3-in.(51 76 mm)dead weight distribution underlayment section.9.5 Remove the weights and the dead weight underlaymentsections from the test panel.9.6 Allow the test panel to dry 24 h at standard conditions.9.7 Place the test panel in a 122F(50C)oven for 72 h.9.8 Remove the test panel from the oven and allow it to coolat standard conditions for 3 h.9.9 Test the specimens in tension shear using a calibrateduniversal testing machine,aligning the upper and lower jaws asperpendicular as possible.Set the test speed at 1 in.(25.4 mm)/min.The test area will be 6 in.2(38.7 cm2).
