The CSI Torsion Tester is used for measuring the relative low temperature stiffening of flexible polymeric materials and coated fabrics. The test procedure is used as a pass-fail test for specified temperature of test.
These test methods may be used to determine the subnormal temperature stiffening of flexible polymers or fabrics coated with flexible polymers. Temperatures at which the low temperature modulus is a specified multiple or ratio of the modulus at room temperature are interpolated from the twist versus temperature curve. These specified ratios of low temperature modulus to room-temperature modulus are called relative moduli. These temperatures at the relative moduli encompass the transition region between the glassy and rubbery states of the materials tested.Standard features include: Torsion Head Assembly
