Designation:D6753/D6753M02(Reapproved 2016)Standard Specification forCoal Tar Adhesive1This standard is issued under the fixed designation D6753/D6753M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers coal tar adhesive with orwithout polymer modification suitable for brush,spray,squee-gee and trowel application to coal tar built up and coal tarmodified bitumen membrane roofings and flashings.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 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 requirements prior to use.2.Referenced Documents2.1 ASTM Standards:2D903 Test Method for Peel or Stripping Strength of Adhe-sive BondsD6511/D6511M Test Methods for Solvent Bearing Bitumi-nous Compounds3.Classification3.1 Type IBrush,squeegee,or spray consistency intendedfor use in the application of field sheet membranes.3.2 Type IIHeavy brushing or trowel consistency intendedfor use in the repair of coal tar roofing and flashings andinstallation of flashings.4.Materials and Manufacture4.1 Coal tar adhesive shall consist of a processed coal tarbase,volatile solvents,mineral stabilizers,with or withoutpolymer modifiers excluding asbestos,mixed to a smoothconsistency.5.Physical Requirements:5.1 The material shall conform to the requirements pre-scribed in Table 1.5.2 UniformityA thoroughly stirred sample shall show noseparation of solvent or settling that cannot be overcome bymoderate stirring after standing for 72 h at room temperature ina closed container.6.Sampling and Test Methods6.1 Test Methods D6511/D6511M:6.2 Strength of LapTest Methods D6511/D6511M asmodified below:6.2.1 Three sets of four specimens shall be prepared,conditioned,and tested at three different temperatures for lapshear strength.6.2.2 Temperatures are to be 10,25,and 60C 50,77,and140F,for conditioning and 10,25,and 32C 50,77,and90F for testing.Preparation of specimens shall be done at alaboratory temperature of 23 6 1.8C 73.4 6 3.6F.6.2.3 Test Specimen and Sample:6.2.3.1 Use a sample of the actual roofing membraneintended for use with the adhesive.6.2.3.2 For each specimen,cut a 1-by 12-in.25-by305-mm transverse strip of membrane that includes theselvage;then cut this strip in half so that one piece contains theselvage and the other is plain.6.2.3.3 Spread the amount of coal tar adhesive recom-mended by the manufacturer evenly over the selvage and thenplace the reverse side of the plain half over the adhesive coatedselvage in the same manner as a field lap would be made.6.2.3.4 Place a 10-lb 4.5-kg mass over the lap.The massshall be large enough to cover the area containing adhesive.After 2 min,remove the mass and condition the specimens asprescribed in Table 1.Use care when handling or movingsamples.6.2.4 ProcedureTest each specimen immediately after thespecified conditioning period in accordance with Test Methods1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing and is the direct responsibility of Subcommittee D08.05on Solvent-Bearing Bituminous Compounds for Roofing and Waterproofing.Current edition approved May 1,2016.Published May 2016.Originallyapproved in 2002.Last previous edition approved in 2009 as D6753/D6753M 02(2009).DOI:10.1520/D6753_D6753M-02R11.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D6511/D6511M.If any specimen fails to meet the minimumvalues specified in Table 1,report the material as failing the lapstrength.6.3 Peel Strength:6.3.1 Test each specimen immediately after the specifiedconditioning period in accordance with Test Method D903.Specimens prepared as in 6.2.3.If any specimen fails to meetthe minimum values specified in Table 1,report the material asfailing the peel strength.7.Inspection7.1 Inspection of the material shall be as agreed uponbetween the purchaser and the supplier as part of the purchasecontract.8.Rejection and Resubmittal8.1 Failure to conform to any of the requirements prescribedin this specification may constitute grounds for rejection.
