Heat Deflection Temperature & Vicat
Measurement of the heat deflection temperature (HDT) is actually a 3-point bending measurement performed with a temperature rise ramp defined by the standard.
Can be applied to:
Test method standards:
ISO 75, ISO 306
The sample is placed on the device and the entire device is placed in an oil bath with a regular rise of temperature.
The softening point (Vicat) of a thermoplastic is the temperature at which a calibrated needle penetrates 1 mm into the material when it is subjected to a rise in temperature.
