Roll the

43、 sheet as describedin 8.4.2.2. Place the second sheet (with release film partiallypeeled off only to expose bottom coating to cover just theselvage) over the selvage positioned in a way to allow 25 mm1 in. 65 % of the salvage below to be exposed per Fig. 1 andD7530/D7530M 103press down the edges of

44、the sheet manually with fingerpressure just hard enough to keep them from lifting. Roll overthe lap as specified in 8.4.2.2. The top sheet must only beadhered over the selvage, and must be loose over plywood pastthe selvage area.8.6.3.2 Cut the bottom out of a 4-L 1-gal can with a canopener and cent

45、er it, bottom side down, on the membranecentering it with the inner edge of the salvage. Apply a 6-mm0.25-in. bead of silicone sealant completely around theoutside rim of the can to bond it to the membrane. As shown inFig. 1, apply the bead of caulk around all three edges of theupper membrane until

46、the end of the salvage area. Allow 2 hfor the sealant to set, then apply another bead around the insiderim of the can.8.6.3.3 After waiting 24 h at ambient temperature for thesealant caulking to cure, fill the can to a depth of 125 mm 5in. with deionized or distilled water. Set the test assembly ove

47、ra container capable of catching all the water in case there is aleak. Place the entire assembly in a refrigeration unit main-tained at 4 6 1C 40 6 2F for a period of three days.8.6.3.4 At the conclusion of the test, remove the testassembly from the refrigeration unit, pour the water from thecan and

48、 blot the inside dry. Peel the can from the sheet then liftthe top sheet, and inspect the underside for any signs of water.8.6.4 ReportObserve and report whether or not water isfound between the plywood and the sheet.
