Tape Dynamic Fatigue Tester

The Tape Dynamic Fatigue Tester is designed for determining surface crack, and separation or break of reinforced layer of a specimen made from tyre tread, tyre sidewall, conveyor belt, rubber outsole, and vamp, diaphragm, tubing during repeatedly flexing and stretching. Shafts with different curvature diameters can be changed for determining different flexing strengths.

ASTM D430A Standard Test Methods for Rubber Deterioration—Dynamic Fatigue. The test methods cover testing procedures that estimate the ability of soft rubber materials to resist dynamic fatigue. No exact correlation between these test results and service is given or implied. This is due to the varied nature of service conditions. These test procedures do yield data that can be used for the comparative evaluation of rubber or composite rubber-fabric materials for their ability to resist dynamic fatigue.
