This standard specifies the method for determining the shear modulus of vulcanized rubber or thermal plasticity rubber and its gluing with rigid plates, which is tested by the quadruple shear method. Shear modulus is an important parameter to measure the deformation ability of rubber under shear force, while gluing with rigid plates directly affects the durability and performance of Rubber. The standard tests the shear modulus of rubber materials and the strength of adhesion to rigid surfaces by the quadruple shear method to ensure the Stability and Reliability of rubber materials under different working conditions.
