Summary of Test Method4.1 These test methods involve allowing a loop of pressure-sensitive adhesive with its backing to be brought into con-trolled contact witha1in.2(25 by 25

10、mm) surface of stainlesssteel, with the only force applied being the weight of thepressure-sensitive article itself. The pressure-sensitive article isthen removed from the substrate, with the force to remove thepressure-sensitive article from the adherend measured by arecording instrument.4.2 Test M

11、ethod A (using a Tensile Tester) applies when aTensile Tester is used to measure loop tack and involves the useof a loop prepared from an 7 in. (175 mm) specimen strip.4.3 Test Method B (using a Loop Tack Tester) applies whena Loop Tack Tester is used to measure loop tack and involvesthe use of a lo

12、op prepared from a 5 in. (125 mm) specimenstrip.5. Significance and Use5.1 These test methods provide a quantitative measure ofthe pressure-sensitive tack property of an adhesive.5.2 These test methods are designed to measure the tackproperty of the adhesive mass. The tack of a given adhesivevaries

13、depending on the backing (generally, stiffer backingslead to higher values).1These test methods are under the jurisdiction of ASTM Committee D14 onAdhesives and are the direct responsibility of Subcommittee D14.50 on Hot Melts,Pressure Sensitives, and Archival Adhesives.Current edition approved Apri

The specimen forms a tear drop shapedloop with the adhesive surface facing out.9.8 Fasten the ends of the loop together, using a strip ofmasking tape 1 in. (25 mm) wide (Fig. 4). The masking tapecovers the ends of the loop, preventing contamination of t

Activate the tensile tester sothat the crosshead moves downward. The mid-section of t

34、hespecimen loop must contact the center of the stainless steelportion of the test fixture. When the crosshead reaches itsminimum position, it will immediately switch direction andmove upward. When the crosshead is at its minimum position,the specimen loop will completely cover the 1 in. (25 mm) area
