Summary of Test Method4.1 Procedure AThe pressure-sensitive tape is mountedon a rigid panel. The adhesive side is exposed.

8、 A strip oflinerboard, which represents the fiberboard, is placed againstthe tape adhesive with controlled pressure. The area of contactis specified. The panel is mounted in a horizontal position. Aspecified mass is fastened to one end of the linerboard. Themass acts to peel the linerboard away from

9、 the adhesive at anangle of 90. The time required to peel the linerboard from thetape is measured.4.2 Procedure BIn this procedure, the fiberboard or thelinerboard representing it is adhered to a rigid panel and thetape peeled from it. In all other respects, the procedure is thesame as Procedure A.5

10、. Significance and Use5.1 This test method is designed to show the adhesion of apressure-sensitive tape to fiberboard when the tape is under aconstant stress. Test data from this test method for some typesof packaging tape relates to tape performance on fiberboardbox closure.5.2 Procedure A should b

11、e used when comparing tapes to anestablished requirement. The requirement may be establishedusing either the standard linerboard or another linerboardrepresenting a specific fiberboard.5.3 Procedure B should be used to rank tapes as to theirability to adhere to fiberboard.6.

Procedure10.1 Procedure A:10.1.1 Adhere the double-coated tape to the firm fingerpressure and remove the liner.10.1.2 Lightly sand the backing of the test tape on the rollfor approximately 250 mm 10 in. with 300-grit sandpaper toremove the easy unwind treatment. Start timing with the

28、 stopwatch. Immediately unwind 300 to 450 mm 12 to 18 in. oftape from a freely rotating roll at a rate of 500 to 750 mm 20to 30 in./s.10.1.3 Center the sanded area of this strip, adhesive side up,on the panel, aligning the long edges parallel with the panellong edges. Trim it to the panel dimensions

Do not allow anyobject to contact the adhesive.10.1.4 Place a mask at the center of the specimen so that the24-mm 1-in. dimension of the hole in the mask lies parallel tothe long dimension of the specimen edges (see Fig. 1). Rubagainst the mask to assure that the tape specimen is welladhered to th

Avoid touchingthe adhesive.10.1.5 At 90 6 5 s, position the linerboard strip (endopposite the hole) to span the mask and enter it lengthwise onthe specimen adhesive. Assure that the correct side of thelinerboard is placed against the specimen adhesive. Do notapply

35、f the panel. Handle the fiberboard only at the edges andcorners so that an area at least 35 mm 1.5 in. square at itscenter is absolutely free of contamination.10.2.3 Place a clean sheet of paper (6.14) on top of thefiberboard. Rub against this to assure that the fiberboard is wellbonded to the doubl

Immediately un-wind 300 to 450 mm 12 to 18 in. of tape from a freely,rotating roll at a rate of 500 to 750 mm 20 to 30 in./s.10.2.5 From the center of this strip, cut a spe

Do not allowadhesive to contact any object.10.2.6 Lay the specimen, adhesive side up, on the work bench and tape the ends down to hold the specimen flat.10.2.7 Apply a mask at one end of the

38、 specimen so that the24-mm 1-in. dimension of the hole lies parallel to the longedges of the specimen (see Fig. 2).10.2.8 Apply the chipboard square to the exposed adhesiveat the other end of the specimen (see Fig. 2).10.2.9 Cut away the taped ends of the specimen. Punch ahole for the hook of the ma

Do not apply any finger pressure to the specimen.Continue timing.10.2.11 Roll the specimen lengthwi

41、e from the roll), add the 200-g mass so that no shock loadis imparted to the specimen and start the timer. Allow the testFIG. 2 Preparation of Specimen for Procedure BD 2860/D 2860M 043to continue until the specimen has peeled free from thefiberboard (see Fig. 3).10.2.14 Void all tests where the fib

When thisoccurs, repeat the test, assuring that the panel, double-coatedtape, and the fiberboard are well bonded together.11. Calculation11.1 To determine the test resul

43、t for each roll of tape,convert each of the five specimen test results to its logarithm.Obtain the arithmetic mean of all logarithms and then convertthe arithmetic mean logarithm back to time by obtaining itsantilogarithm. This final step gives the test result for the roll oftape under consideration

Precision and Bias13.1 SummaryThe

47、difference between two single obser-vations should not exceed 27.7 % of the average of the twoobservations in transformed units in 95 out of 100 cases whenboth observations are taken by the same well-trained operatorusing the same piece of test equipment and specimens ran-domly drawn from the same s

48、ample of material. Largerdifferences may occur under all other circumstances. The truevalue of adhesion to fiberboard at 90 angle under constantstress can only be defined in terms of a specific test method.Within this limitation, Test Method D 2860/D 2860M has noknown bias.
