A. Introduction:
H.D.T. Heat Deflection testing specimen is placed on the simple beam of structure and main function is test of center position 0.445MPA or 1.82MPA of bending stress. The Heat Deflection testing environment temperature increase 2℃/min. To measure specimen center of deformation in 0.25mm temperature value as deformation temperature.
This Heat Deflection test is suitable for the material at 27℃ which still as hard material. The specimen length 127mm, the deviation between is 0.13mm. The thickness is 13mm and width 3mm to 13mm.
A wide range of accessories such as grips, fixtures, chambers and high travel extensometers are available to match most applications and test samples.
H.D.T. Heat Deflection Tester confirms to ASTM D648, ISO 75-1 Standard
