A recurrent concern in the design and safety analysis of packaging for the transportation of radioactive material is to characterize the leaktightness of elastomeric gaskets at low and high temperatures.

Indeed, most gasket suppliers specify minimum and maximum allowable temperatures but they do not specify what are the acceptance criteria, the seal life of the gaskets at these temperatures and how these minimum and maximum temperatures are determined. Based on this type of data, it is difficult to guarantee the leaktightness of gaskets submitted to fluctuating temperatures in industrial applications.
