8、st 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) for testing. P
9、reparation 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 t
10、hat 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 i
11、n 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 Procedu
12、reTest each specimen immediately after thespecified conditioning period in accordance with Test MethodsD 6511. If any specimen fails to meet the minimum valuesspecified in Table 1, report the material as failing the lapstrength.6.3 Peel Strength:6.3.1 Test each specimen immediately after the specifi
