This standard specifies a test method for determining the adhesive strength of an adhesive between two flexible materials, such as plastic films, rubber, etc., with the aim of evaluating the T-peel resistance of bonded specimens under specified conditions. The standard provides detailed requirements for specimen preparation, conditioning, testing procedures, and result processing. The core equipment for performing this test is a peel strength tester, commonly referred to as an electronic peel testing machine. This instrument applies a T-peel force to the specimen at a constant rate (e.g., as recommended by the standard, 100 millimeters per minute) and accurately records the changes in force during the peeling process, thereby calculating the average peel strength.
