This standard specifies a method for determining the disbonding gluing performance of self-adhesive tapes, which is applicable to various types of self-adhesive tape materials. Through the disbonding test, the adhesive strength of the tape after contact with the standard test substrate is evaluated. This test method can effectively reflect the parameters such as the initial adhesion force and disbonding force of the tape by measuring the force value required when the tape is disbonded, and then evaluate its adhesion ability in actual use. The standard is widely used in Encasement, Label, Construction and Automotive industries to help ensure the mass, Reliability and application effect of self-adhesive tapes, providing an important basis for product design, quality control and performance verification.
