Rubber-like materials are widely used in the industry, aeronautic or automotive. In these applications, fatigue damage must be taken into account, which requires very long and costly experimental campaigns. One of the main goals of the research on this kind of materials is to improve the prediction of fatigue life with shorter and cheaper tests. This paper describes the first part of an ongoing research about the study of the fatigue behavior of dumbbell specimen made of polychloroprene with infrared thermography. It deals with the definition of two new thermal parameters for the fatigue behavior analysis. The first one is the heating rate and is defined in the first 1500 cycles giving a linear relationship with the stabilized temperature of the specimen. The second thermal parameter is the number of cycles until the stabilization of the surface temperature of the sample. Changes in the thermal behavior observed during
