Rubber - Determination of viscosity and stress relaxation using a rotorless sealed shear rheometer
|Publication Date:||15 September 2012|
|ICS Code (Rubber):||83.060|
This International Standard describes a method for the determination of the viscosity and stress relaxation of raw or compounded rubber under specified conditions.
The viscosity determination consists of a constant strain, temperature and frequency test in which the elastic and the loss components of the complex shear modulus can be determined.
The determination of stress relaxation consists of a constant static and temperature test in which the torque decrease can be determined.
