(38.7 cm2or 51 3 76 mm) area of the adhesive (Fig.1).9.3 Place a 2 3 3-in. (51 3 76 mm) underlayment sectionon top of each duck cloth piece for dead weight distribution(Fig.
16、2).9.4 Place a 10-lb weight on each 2 3 3-in. (51 3 76 mm)dead weight distribution underlayment section.9.5 Remove the weights and the dead weight underlaymentsections from the test panel.9.6 Allow the test panel to dry 24 h at standard conditions.9.7 Place the test panel in a 122F (50C) oven for 72
