148-HD HEAT DISTORTION TESTER


This Heat Distortion Tester is used for evaluation of the heat resistance of plastic or polymer. By loading specified bending stress to the test specimen while increasing the test temperature of the oil bath at a certain rate, the instrument will measure the temperature at which the test specimen reaches standard deflection or deformation. This parameter is called heat distortion temperature or heat deflection temperature (HDT, HDTUL, or DTUL). The tester is also used for conducting the VICAT softening temperature test and the ball pressure test. This instrument is also in comply with International Standards: JIS-K7191-1, JIS-K7206, ASTM-D648, ASTM-D1525, IEC-335-1, ISO-75-1, ISO-306

There are various models available with 3, 4 or 6 testing stations.
