The NF X41-002-2019 standard specifies a Measuring method for static shear adhesion of self-adhesive tapes, which is designed to evaluate the adhesion performance of self-adhesive tapes under static load. This test determines the adhesion Stability and durability of self-adhesive tapes by fixing them to the surface of a standard substrate under specific conditions, applying shear force and testing them for a specified time. Static shear adhesion testing can effectively reflect the adhesion performance of tapes during long-term use, especially under temperature changes or pressure. This method is suitable for quality control and Product Research & Development of various self-adhesive tapes, and is widely used in Encasement, electronics, construction and other industries to ensure the Reliability and performance of tape products in practical applications.
