Description
H.D.T. Heat Deflection Tester is suitable for material which is still hard at 27℃. The specimen, placed at the simple beam for testing, is given a flexion stress of 0.445MPA or 1.82MPA at the center. The ambient temperature of the test in increased by 2 degrees Celsius per minute. When the specimen’s center undergoes a deflection of 0.254mm (ASTM), 0.32mm (ISO edgewise), 0.34mm(ISO flatwise) the temperature is determined as the specimen’s deflection temperature.
The tester is able to test both H.D.T heat and Vicat heat by exchanging the specimen holde.
