1、Designation: D 6753/D 6753M 02 (Reapproved 2009)Standard Specification forCoal Tar Adhesive1This standard is issued under the fixed designation D 6753/D 6753M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revisi

2、on. 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 a

3、pplication 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 indepe

4、ndently 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 an

5、d health practices and determine the applica-bility of regulatory requirements prior to use.2.

Materials and Manufacture4.1 Coal tar adhesive shall consist of a proc

7、essed coal tarbase, volatile solvents, mineral stabilizers, with or withoutpolymer modifiers excluding asbestos, mixed to a smoothconsistency.5. Physical Requirements5.1 The material shall conform to the requirements pre-scribed in Table 1.5.2 UniformityA thoroughly stirred sample shall show nosepar

8、ation 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 D 6511:6.2 Strength of LapTest Methods D 6511 as modifiedbelow:6.2.1 Three sets of four specimens shall be prepared,

9、con-ditioned, and tested at three different temperatures for lap shearstrength.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

10、.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 th

11、e 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. Th

12、e 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 Met
