Description

The specimen is given a fixed 10N force (or 50N) at the center with a standard Ø1.13 mm pin, and the temperature should increase by 50 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. 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.
The test is suitable for material that is hard at room temperature. The specimen is 3 to 6.5
mm thick and the dimension is at least 10 x 10 mm or Ø10mm.

Specimen preparation

At least two flat, smooth, parallel specimens with thickness 3 to 6.5mm and area 10 x 10 mm2 or Ø10mm are needed.
If the specimen is thicker than 6mm, reduce it by half on one side and keep the other side unchanged.
If the thickness is below 2.5 mm, stack the specimen with less than 3 other materials and make the combination at least 3 mm thick.
