c. Adhesiveness test:

Testing conditions: This test shall be performed in an atmosphere maintained at standard conditions as specified in TAPPI method T

402. The test paper shall be conditioned to equilibrium with these conditions prior to testing. The tape specimens shall not be conditioned prior to testing.

Test:� Cut four (4) 12� X 6� specimens of standard reference material, as specified in ASTM D 3654²^/, two each in machine direction (MD) and cross direction (CD). Cut and completely moisten 4 randomly selected tape test specimens 12 inches long by the full tape width, utilizing an automatic dispenser conforming to CID A-A- 79. Fold over one inch of the tape end so that the adhesive sides are together to form a one inch tab to facilitate tape removal efforts. At the end of 15 seconds, apply each tape specimen to the test paper, 2 in MD and 2 in CD of the standard reference material. Roll the tape once in each direction with a soft rubber covered hinged iron roller, weighing 16 pounds + 1/4 lb., 3-1/2 in. + 1/8 in. wide and having an overall diameter of 5 in. + 1/8 in. at a rate of 12 inches/min. Within 5 seconds after the tape is applied on the paper, gently lift the tab to expose not more than 3 inches of the tape (one MD and one CD) and observe the tackiness of the gum. The gum shall show, a pronounced tackiness. (The portion of the specimens lifted to observe tackiness shall not be reapplied.) After twenty-

Pour hours elapsed time, determine the ease of removal of the specimens (2 MD and 2 CD). The adhesive quality shall be considered satisfactory if:
