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.Heat Distortion Tester HDT is used for heat distortion test / heat deflection test as well as VICAT Softening Temperature test of plastic / polymer. HOME; ABOUT US; . with the ability to measure heat distortion temperature (HDT), VICAT softening temperature, and ball pressure. . LMS Scientific Solution Sdn Bhd (708381-T) D10-3-G, Block D10 . 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 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.
Traditional 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 have HDT values of up to 500°C. Aluminum oxide is an alternative heating medium for high-temperature applications.HDT/Vicat testing enabled Powered Raise/Lower of test stations Advanced microprocessor control 3/6 sample test stations Automatic Station Lift (6 Station option only) Digital temperature control Temperature range to 300°C .
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 heatingThis can be divided into Vicat softening temperature and HDT (heat deflection temperature). In both methods an oil-bath is heated at a defined rate and the temperature is recorded at a deflection or indentation depth specified by the .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.

Vicat softening temperature und heat distortion temperature - data @inproceedings{Kotter2014VicatST, title={Vicat softening temperature und heat distortion temperature - data}, author={Ina Kotter and Wolfgang Grellmann . 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 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)Distributor of SKZ Industrial SKZ144B Vicat Heating-distortion Temperature Meter (~300℃, PC type) Jinuosh, Cell Instruments, HAIDA, TONYHK, Yasuda, SKZ Industrial, TQCSheen, Uby Tech, Lonroy, Hongdu Call for best price
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 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 .
Feature . 1. Using meter to measure distortion and temperature controller to set temperature. 2. S pecimen stand can automatically go up and down and test 3 specimens in one time.. Standard: ASTM-D1525, ASTM-D648, DIN53460,DIN53461,ISO-306,ISO-75JIS-K7191-1, K7206, ASTM-D648, D1525, IEC-335-1, ISO-75-1, ISO-306. This tester is used to evaluate the heat resistance of plastic. By loading specified bending stress to the test specimen while increasing the test temperature of the oil bath at a certain rate, the operator is to report the temperature at which the test specimen reaches standard deflection.
