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, the temperature is determined as the specimen’s deflection temperature. The tester is equipped with touch screen that guides users step by step. During the process, the specimen holder and the weight frame automatically rise and descend to facilitate specimen’s installment and load calculation required by the test. A user-friendly interface and standardized process are designed to orientate users in the shortest possible and to reduce test errors. The display shows specimen temperature and LVDT displacement at each station. The temperature record stops when it reaches deflection value and the tester starts cooling down. Smart testing process is time-saving and requires only a minimum of testers.
This test is suitable for material which is still hard at 27℃. The specimen is 127mm long, with error value±0.13cm. It is 13mm thick and 3-13mm wide.
