- Scope
- This document describes a test method for measuring the viscosity and stress relaxation of raw and mixed rubber under specified conditions. The determination of viscosity is carried out under the condition of constant strain, temperature and frequency, and the elastic shear modulus and loss shear modulus in the complex shear modulus can be determined during the test. The determination of shear stress relaxation is carried out under the condition of constant static strain and temperature, and the drop of torque can be measured during the test.
