1 Scope

This document describes the procedures for determining the mechanical, electrical, thermal and other properties of thermosetting molding compounds at elevated temperatures. method. This method is used to determine the relative performance temperature (RPT) of thermoset molding compounds. RPT is useful for describing the short-term nature of materials at high temperatures can be necessary. Combined with long-term performance evaluation of polymeric materials, RPT provides designers and engineers with a more complete understanding of the performance of materials used at high temperatures. expected performance of the material. This document applies to thermosetting molding compounds.
