This standard specifies a test method for the determination of adhesion between vulcanized rubber or thermal plasticity rubber and rigid substrates using the 90 ° disbonding method. The 90 ° disbonding method is a commonly used technique for the measurement of Adhesive strength of rubber materials and substrates, by applying disbonding force and measuring the force value during the disbonding process. This method is widely used in the automotive, electronics, Encasement and other industries to help ensure the adhesion performance and durability of rubber materials in practical applications.
