Summary of Test Method4.1 Procedure AThe pressure-sensitive tape is mounted on a rigid panel. The adhesive sid
9、e is exposed. A strip of linerboard,which represents the fiberboard, is placed against the tape adhesive with controlled pressure. The area of contact is specified. Thepanel is mounted in a horizontal position. A specified mass is fastened to one end of the linerboard. The mass acts to peel theliner
10、board away from the adhesive at an angle of 90. The time required to peel the linerboard from the tape is measured.4.2 Procedure BIn this procedure, the fiberboard or the linerboard representing it is adhered to a rigid panel and the tapepeeled from it. In all other respects, the procedure is the sa
11、me as Procedure A.5. Significance and Use5.1 This test method is designed to show the adhesion of a pressure-sensitive tape to fiberboard when the tape is under a constantstress. Test data from this test method for some types of packaging tape relates to tape performance on fiberboard box closure.1

Procedure10.1 Procedure A:10.1.1 Adhere the double-coated tape to the panel with firm finger pressure and remove the liner.10.1.2 Lightl
31、y sand the backing of the test tape on the roll for approximately 250 mm 10 in. with 300-grit sandpaper to removethe easy unwind treatment. Start timing with the stop watch. Immediately unwind 300 to 450 mm 12 to 18 in. of tape from afreely rotating roll at a rate of 500 to 750 mm 20 to 30 in./s.10.
32、1.3 Center the sanded area of this strip, adhesive side up, on the panel, aligning the long edges parallel with the panel longedges. Trim it to the panel dimensions. Do not allow any object to contact the adhesive.10.1.4 Place a mask at the center of the specimen so that the 24-mm 1-in. dimension of
33、 the hole in the mask lies parallel tothe long dimension of the specimen edges (see Fig. 1). Rub against the mask to assure that the tape specimen is well adhered tothe double-coated tape on the panel. Avoid touching the adhesive.10.1.5 At 9065 s, position the linerboard strip (end opposite the hole
34、) to span the mask and enter it lengthwise on the specimenadhesive. Ensure that the correct side of the linerboard is placed against the specimen adhesive. Do not apply any finger pressureto the specimen. Continue timing.10.1.6 Roll the linerboard against the specimen lengthwise twice each way at a
35、rate of 10 6 0.5 mm/s 24 6 0.5 in./min usingthe rubber-covered roller.10.1.7 Immediately set the panel, specimen side down, into the test stand, assuring that it will remain in a horizontal planethroughout the test.FIG. 2 Preparation of Specimen for Procedure BD2860/D2860M 17310.1.8 At 180 6 5 s (3
36、min from unwinding the tape from the roll), add the 200-g mass so that no shock load is imparted tothe linerboard, and immediately start the time. Allow the test to continue until the linerboard has peeled free from the specimenadhesive.10.1.9 Void all tests where the tape (test specimen) has pulled
37、 away from the panel (either the specimen from the double-coatedtape or the double-coated tape from the panel). When this occurs, repeat the test assuring that the panel, the double-coated tape,and the test specimen are well bonded together.10.2 Procedure B:10.2.1 Adhere the double-coated tape to th
38、e panel with firm finger pressure and remove the liner.10.2.2 Superimpose the fiberboard (or linerboard) on the double-coated tape, exposing the correct side and assuring that themachine direction is at a right angle to the long dimension of the panel. Handle the fiberboard only at the edges and cor
39、ners sothat an area at least 35 mm 1.5 in. square at its center is absolutely free of contamination.10.2.3 Place a clean sheet of paper (6.14) on top of the fiberboard. Rub against this to assure that the fiberboard is well bondedto the double-coated tape on the panel. Do not rub the fiberboard surf
40、ace with the paper or fingers.10.2.4 Start timing with the stop watch. Immediately unwind 300 to 450 mm 12 to 18 in. of tape from a freely, rotating rollat a rate of 500 to 750 mm 20 to 30 in./s.10.2.5 From the center of this strip, cut a specimen 24 6 0.25 mm 1.0 6 0.01 in. wide and at least 180 mm
41、 7 in. in length.Handle this strip by its ends only. Do not allow adhesive to contact any object.10.2.6 Lay the specimen, adhesive side up, on the work b ench bench and tape the ends down to hold the specimen flat.10.2.7 Apply a mask at one end of the specimen so that the 24-mm 1-in. dimension of th
42、e hole lies parallel to the long edgesof the specimen (see Fig. 2).10.2.8 Apply the chipboard square to the exposed adhesive at the other end of the specimen (see Fig. 2).10.2.9 Cut away the taped ends of the specimen. Punch a hole for the hook of the mass in the chipboard.10.2.10 At 90 6 5 s, posit
43、ion the specimen lengthwise on the fiberboard, adhesive down, so that the 1 by 1-in. 24 by 24-mmadhesive area is approximately centered on the fiberboard. Do not apply any finger pressure to the specimen. Continue timing.10.2.11 Roll the specimen lengthwise twice each way at a rate of 10.060.2 mm/s
44、2460.5 in./min, using the rubber-coveredroller.10.2.12 Immediately set the panel, specimen side down, into the test stand, assuring that it will remain in a horizontal planethroughout the test.10.2.13 At 180 6 5 s (a total of 3 min from unwinding the tape from the roll), add the 200-g mass so that n
45、o shock load isimparted to the specimen and start the timer.Allow the test to continue until the specimen has peeled free from the fiberboard (seeFig. 3).10.2.14 Void all tests where the fiberboard has pulled away from the panel (either the fiberboard from the double-coated tapeor the double-coated
46、tape from the panel). When this occurs, repeat the test, assuring that the panel, double-coated tape, and thefiberboard are well bonded together.NOTE 1Fix panel securely in a horizontal plane.FIG. 3 Test Assembly for Procedure BD2860/D2860M 17411. Calculation11.1 To determine the test result for eac
47、h roll of tape, convert each of the five specimen test results to its logarithm. Obtain thearithmetic mean of all logarithms and then convert the arithmetic mean logarithm back to time by obtaining its antilogarithm. Thisfinal step gives the test result for the roll of tape under consideration. No s
48、ingle specimen value shall be considered asrepresentative of the roll under test.12.
