Advanced HDT VICAT Testing Machine for Precise Plastic Vicat
Softening Temperature Determination
Equipment introduction:
Vicat Softening Temperature (VST) Definition
The Vicat Softening Temperature (VST) is defined as the temperature
at which a flat-ended needle with a 1 mm² circular cross-sectional
area penetrates a thermoplastic specimen to a depth of 1 mm. This
test is conducted under a specified perpendicular load (force) and
at a selected uniform rate of temperature rise—consistent with
international testing standards (e.g., ISO 306, ASTM D1525).
Core Operational & Data Processing Functions
The Vicat Testing Machine adopts PC-based control, integrating
high-precision measurement and intelligent operation features:
- Equipped with digital micrometers for high-accuracy deformation
measurement, ensuring reliable test data acquisition.
- Supports real-time curve plotting, enabling visual monitoring of
the penetration process and temperature-deformation relationship.
- Test data can be directly subjected to secondary processing on the
PC; it is also exportable to Microsoft Office software (Word,
Excel) for further editing, typesetting, and report generation.
- The sample frame is designed with automatic lifting functionality,
which enhances operational efficiency, reduces manual intervention,
and ensures consistent specimen positioning—optimizing test
repeatability.
