Describes the principles and procedures for estimating the life-time and maximum temperature of use of vulcanized or thermoplastic rubbers, using an Arrhenius plot. Is suitable for different tests on rubber, but for tests under stress or deformation (creep, relaxation, etc.) physical (viscoelastic) changes of material cannot easily be separated from any chemical change . Then the Arrhenius equation is no longer the only possible model, and the Williams, Landel, Ferry (WLF) equation may be more suitable to represent the change in the material as a function of time.
