Abstract
Deflection Temperature Under Load (DTUL) is an experimental value commonly used by designers to characterize a plastic in a high temperature environment. This value is currently measured by a standard test procedure specified by the ASTM D-648. A theoretical analysis of this test was made and computer programs were developed to calculate the Deflection Temperaure of Plastics Under Load based upon temperature dependent flexural modulus data and temperature dependent thermal properties of the plastics of interest. The results obtained from the theoretical analysis agree closely with the experimental values found in the literature for two resins. An analysis of the theoretical results clearly indicate that the experimentally determined DTUL value can be varied by selecting experimental conditions and part geometory.
