Vicat Heat Deflection Tester
Confirm to ASTM D648 ISO 75-1 Standard
The specimen is given a fixed 10N force (or 50N) at the center with a standard Ø1 mm pin, and the temperature should increase by 50 (or 120) degrees Celsius per hour. When the penetration depth of specimen reaches 1mm, the temperature is determined as the Vicat softening temperature VST. The tester is equipped with touch screen that guides users step by step. A user-friendly interface and standardized process are designed to orientate users in the shortest time possible and to reduce test errors. Each working station is equipped with temperature and deflection sensor. During the test, the display shows real-time temperature and deflection on each specimen. When it reaches deflection value, it will record the temperature and stops and start cooling system. Smart testing process is time-saving and requires only a minimum of testers.
