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)’. 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)Heat Deflection and Vicat Softening Temperature tests are essential for evaluating the thermal behavior of plastics under heat and stress. The HDT Vicat Testers, used for determining both the Heat Deflection Temperature (HDT) and Vicat Softening Temperature, help manufacturers ensure their materials meet stringent thermal performance requirements.

the standard test specimen and the temperature is raised at a uniform rate. Note: When ISO 75 is used the result is referred to as the Heat Distortion Temperature or Heat Deflection Temperature (HDT). Real Life Performance Any test is only an approximation of the real life behavior. Tests are naturally accelerated toTraditional HDT Vicat test methods use silicon oil as the heating medium, but silicon oil has a high-temperature limit of 300°C. This temperature is not high enough to test new families of materials known as techno-polymers, which .In contrast, for the heat distortion temperature, the temperature at which a specified amount of displacement is reached is determined by gradually heating (120℃/hr)in a state in which a constant load (according to ISO 72, the low .

The heat distortion temperature test is determined by the following test procedure outlined in ASTM D648. The test specimen is loaded in three-point bending in the edgewise direction. Heat distortion temperature This material test assesses the dimensional stability of plastics as a function of temperature. It determines the temperature at which a specified deflection occurs .
The ISO 306, ASTM D1525, ISO 75 and ASTM D648 standards describe the determination of heat deflection temperature (HDT) and Vicat softening temperature (VST). The heat deflection temperature and Vicat softening temperature are characteristic values, which under comparable conditions, provide an indication of the maximum service temperature of a plastic. The test specification for the Vicat softening temperature testing is ASTM D1525 and ISO 306. Compared with the Heat Deflection Temperature (HDT), Vicat softening temperature test measures the temperature at which the specimen loses its stiffness and softens. HDT test measures the temperature at which the specimen loses its load bearing .The automotive heat deflection-Vicat softening point tester (model XWR-300) supplied by Jingjian Testing Instru-ment Co. Ltd. (Chengde, China) was used in this work to measure the heat distortion temperature of the blend and composites. The heat distortion temperature tests were conducted according to ISO75-2 standard, the heatingISO 75 Plastics -- Determination of temperature of deflection under load ISO 306 Plastics -- Thermoplastic materials -- Determination of Vicat softening temperature (VST) ISO 2507 Thermoplastics pipes and fittings -- Vicat softening temperature ASTM D648 Standard Test Method for Deflection Temperature of Plastics Under Flexural Load in the Edgewise Position .
