6、ionsMany of the terms in this test method aredefined in Terminology D 907.4. Significance and Use4.1 In selecting or developing a carpet adhesive, it is criticalto have knowledge regarding how well the adhesive will bondto the desired underlayment. Shear loading simulates a com-mon failure mode.4.2

14、Procedure9.1 Hold the trowel at a 45 angle and spread sufficientadhesive to cover the bonding areas.9.2 Wait 10 min and place three pieces of duck clothperpendicular to the trowel pattern, each covering a 6-in.2or3 3 2-in. (38.7 cm2or 51 3 76 mm) area of the adhesive (Fig.1).9.3 Place a 2 3 3-in. (5
15、1 3 76 mm) underlayment sectionon top of each duck cloth piece for dead weight distribution(Fig. 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 t
16、est panel to dry 24 h at standard conditions.9.7 Place the test panel in a 122F (50C) oven for 72 h.9.8 Remove the test panel from the oven and allow it to coolat standard conditions for 3 h.9.9 Test the specimens in tension shear using a calibrateduniversal testing machine, aligning the upper and l
17、ower jaws asperpendicular as possible. Set the test speed at 1 in. (25.4 mm)/min. The test area will be 6 in.2(38.7 cm2).9.10 Record the three shear values in pounds-force.10. Calculation10.1 Calculate the shear strength (psi) of the individualspecimens as follows:S 5SV6(1)where:S = shear strength (
18、psi), andSV = shear value reading from the universal test machine.10.2 Calculate the average shear strength of the individualspecimens as follows:SAVE5(S3(2)where:SAVE= the average shear strength (psi) of the three shearstrength values.11.
