1、Designation: D 6753 02 (Reapproved 2008)Standard Specification forCoal Tar Adhesive1This standard is issued under the fixed designation D 6753; 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

2、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 coal tar adhesive with orwithout polymer modification suitable for brush, spray, squee-gee and trowel application to co

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

9、) 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 str

10、ip 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
