Since the revision of the calculation standard EN1591 (2014 version), pressure has strongly increased to improve certain parameters by the manufacturers of PTFE sheets and gaskets. The revised version of this standard demands substantially improved mechanical material properties for successful flange calculations. In particular, the flow behavior
