The heat distortion temperature is the temperature at which a piece of PVC, placed in the heat medium with a bending load applied onto it, reaches a specified deflection as temperature rises. The Vicat softening temperature is defined as the temperature where the needle shaped penetrator sinks into the test piece to a specified depth.
The Heat Deflection Temperature (HDT), or Heat Distortion Temperature, is a measure of a polymer’s resistance to alteration under a given load at an elevated temperature. It is also known as the ‘deflection temperature under load’ (DTUL) or ‘heat deflection temperature under load (HDTUL)’.
Discover the 3 & 6 Station Heat Distortion & Vicat Softening Point Apparatus, providing the highest quality of testing equipment. . Each test station is fitted with a PT100 platinum resistance thermometer which accurately records the temperature next to the sample under test to 0.1°C and an electronic displacement transducer which measures . The HDT test determines the temperature where the material under test deforms 0.25 mm (0.010 inch) under load in a three point bending geometry. Figure 1. Loading geometry for ASTM D648 heat deflection temperature test. The load is calculated so that the specimen can be subjected to a fiber stress of: 0.455 MPa (66 psi) 1.82 MPa (264 psi)
