The HDT Vicat tester (Model Vicat A6060) manufactured by Bayerteq is an advanced thermal deflection testing system engineered for determining the Heat Deflection Temperature (HDT) and Vicat Softening Temperature (VST) of raw polymers, rigid plastics, and pipe fittings. Designed in strict accordance with international standards including ISO 75, ISO 306, ASTM D648, ASTM D1525, and ISO 2507, this high-precision instrument delivers reliable thermal characterization for material qualification, compounding, and certification laboratories.
Heat resistance is a critical operational parameter for polymers used in automotive, plumbing, and structural engineering. The Bayerteq HDT Vicat tester heats a methyl silicone oil bath at precise, standardized heating rates (50 °C/h or 120 °C/h) while applying calibrated flexural stresses (Method HDT A, B, C) or indenter needle loads (Vicat A50, A120, B50, B120), continuously recording the exact temperature at which standard deflection or 1 mm needle penetration occurs.
HDT Vicat Tester Architecture & Station Capabilities
The Vicat A6060 series is engineered with heavy-duty automated mechanics and high-resolution digital sensing:
- Multi-Station Modular Capacity (3 to 6 Stations): Available with 3, 4, 5, or 6 test stations. Each station features an independent temperature measuring sensor directly adjacent to the specimen, guaranteeing uniform thermal monitoring across all positions.
- Ultra-Low Thermal Expansion Specimen Frames: Manufactured from advanced low-expansion alloy materials limiting frame thermal drift to just 0.005 mm per 100 °C, eliminating measurement distortion under thermal ramps up to 300 °C.
- Motorized Automatic Lifting & Weight Loading: Test stations lift and lower automatically into the oil bath via motorized drives. Calibrated test weights load and offload automatically during the lifting cycle to minimize operator handling.
- High-Resolution Digital Micrometers: Electronic digital deformation gauges with dedicated communication interfaces deliver displacement measurement accuracy within 0.005 mm.
- Environmental & Thermal Protection: Integrated forced smoke exhaust ventilation extracts oil fumes safely from the testing bay, backed by an independent secondary thermal circuit that halts heating if bath temperature exceeds permissible thresholds.
Operated via an integrated color touchscreen or connected PC with Bayerteq software, this HDT Vicat tester logs real-time temperature-deflection curves and exports compliance test certificates automatically.

Key Operational & Engineering Advantages
Dedicated Sensor per Station
Each individual station is equipped with its own dedicated RTD temperature sensor positioned at the sample, eliminating thermal gradients across the bath.
Minimal Frame Thermal Drift
Specially developed frame metallurgy restricts thermal expansion to 0.005 mm / 100 °C, preventing false deflection readings during heating.
Motorized Station Lifting & Loading
Automated electric lifting mechanism lowers and raises the test frames smoothly, with automatic weight placement during the loading process.
Automatic Smoke Exhaust Fan
Integrated vapor extraction hood captures silicone oil fumes at elevated temperatures, maintaining clean, safe air quality in the laboratory.
Digital Micrometer Accuracy
High-precision digital micrometers with electronic communication provide 0.005 mm accuracy, delivering repeatable data even under the lightest loads.
Dual Protection Safety Loop
Independent secondary hardware temperature circuit cuts heater power immediately if oil bath temperature exceeds programmed limits.
