Rubber. Determination of viscosity and stress relaxation using a rotorless sealed shear rheometer
| Published By | Publication Date | Number of Pages |
| BSI | 2012 | 26 |
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 strain and temperature test in which the torque decrease can be determined.
