1.1 These test methods cover the determination of the adhesion strength between plies of fabric bonded with rubber or the adhesion ofthe rubber layer in articles made from rubber attached to other material. They are applicable only when the adhered surfaces are approximately plane or uniformly circular as in belting, hose, tire carcasses, or rubber-covered sheet metal.
1.2 When the adhered surfaces contain sharp bends, angles,or other gross irregularities that cannot be avoided in preparing test specimens, special test methods must be employed for evaluating adhesion.
