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 0.25mm(ASTM), 0.32mm(ISO edgewise), 0.34mm(ISO flatwise) the temperature is determined as the specimen’s deflection temperature.
