Simulating DTUL (ASTM D 648) Experiments with the TMA 943 or TMA 2940.
简介:Heat Deflection Temperature (HDT) and Deflection Temperature Under Load (DTUL) are equivalent terms that reflect

the temperature at which a material subjected to a three-point bending load deforms to a pre-determined position. The
actual force applied to the sample and the amount of deflection required depend upon the sample geometry. ASTM D648
defines a standard set of these parameters. However, alternative arrangements such as the TMA flexure probe configuration
(Figure 1) can be used to simulate this ASTM method, using the procedure described below.详细>
