In stock
More info
Description / Abstract:
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.
