HDT Vicat Testing Instrument​

HDT/Vicat Tester – Precise Heat Resistance Analysis for Plastic Materials
ZwickRoell's HDT/Vicat testers, available through ZRS Testing Systems, are used to determine the properties of plastic materials heat deflection temperature (HDT) and Vicat softening temperature (VST) in accordance with ISO and ASTM standards. A fully automated test sequence ensures consistent and repeatable results – regardless of the carrier.

The system measures according to:

• ISO 75 / ASTM D648 for HDT in thermoplastics, thermosets, and fiber-reinforced materials

• ISO 306 / ASTM D1525 for VST on thermoplastics and pipes

• Also creep behavior under bending stress can be analyzed

The testers are available with 2, 4, or 6 parallel test stations and cover temperatures up to 300 °C, making them suitable for both standard materials and higher-performance plastics. They can be operated independently via a touchscreen or integrated with testXpert software for comprehensive data analysis and traceability.

Applications:
Perfect for research and development, receiving goods, production monitoring, and technical training. Its intuitive design and robust mechanics make the system a reliable tool in laboratories with high demands for temperature-tolerance data.

ZRS supplies, installs, services, and calibrates the entire product line—so you can ensure quality in every sample.
