Rubber — Determination of viscosity and stress relaxation using a rotorless sealed shear rheometer ISO 13145:2012

Publication date:   Sep 20, 2012

Scope

ISO 13145:2012 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.
