11、selvage 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 ov
12、er 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
