Torsional Testing

Smithers Rapra have a wealth of experience in determining the low temperature properties of vulcanized and thermoplastics rubbers.

The low temperature stiffening procedure, known as the Gehman test, measures the torsional stiffness of test pieces as a function of temperature, starting from a low temperature of approximately -70°C. The technique yields torsional and relative modulus values as well as an apparent torsional modulus of rigidity value.

Standards and Accreditation

Smithers Rapra are ISO 17025 accredited to test rubber materials to ISO 1432.
