This International Standard describes a method for the determination of the viscosity and stress relaxation of raw or compounded rubber under specified conditions.<\/p>\n
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.<\/p>\n
The determination of stress relaxation consists of a constant static strain and temperature test in which the torque decrease can be determined.<\/p>\n
