GB/T 7760-2003 stipulates the use of 90 ° disbonding method to determine the adhesive strength of vulcanized rubber or thermal plasticity rubber and hard plates. The standard specifies the applicable rubber type and range of plates, elaborates the requirements for sample preparation, and specifies the equipment such as Tensile machine. Specifies the operation process of 90 ° disbonding test, including tensile rate control, data collection, etc., and also explains the calculation and representation of the results. Adhesive strength is related to product mass and service life. This standard provides a unified method for gluing performance testing of rubber and plates, helping enterprises to control product mass and promote industry standardization.
