This standard specifies the test method for the warping performance of adhesive tapes, which is applicable to the evaluation of the warping performance of adhesive tapes by the winding method. Warping refers to whether the end of the adhesive tape will separate from the surface after being bonded to a certain surface of curvature. This standard is divided into two cases of overlapping bonding and non-overlapping bonding for determination. In the overlap bonding test, the degree of warping of the end of the adhesive tape is evaluated after the adhesive tape is wound to form an adhesive greater than 360 °; in the non-overlapping bonding test, the adhesive tape is wound to form an adhesive not greater than 360 ° for evaluation. This test helps to evaluate the Reliability and Stability of the adhesive tape in practical applications.
