This standard specifies in detail the test method for evaluating the peel resistance of adhesive tapes under constant load, providing a unified technical basis for the research and development, production quality control, and performance evaluation of adhesive tape products. Its core principle involves suspending standard weights vertically or at specific angles to simulate the sustained static stress that adhesive tapes experience in practical use, thereby determining their dynamic durability against progressive peeling. In practice, the test is typically conducted using an electronic tensile testing machine or static load testing machine equipped with specialized peeling fixtures. These instruments can precisely control the test load and monitor the relationship between peel displacement and time in real time, ensuring the accuracy and repeatability of the test results.
