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