Determination of heat deflection temperature to ISO 75 & ISO 306

► Heat deflection temperature determination to ISO 75 and ISO 306 ◄

The Amsler HDT/Vicat Allround instrument is designed for convenient testing in research and development, goods inwards checks and production monitoring. Depending on the requirement, the instrument can be equipped with two, four or six measuring stations.


► Determination of Heat Distortion and Vicat softening temperature with the Amsler HDT/Vicat Allround ◄

In addition to determination of the heat deflection temperature (HDT), the new Amsler HDT/Vicat is also ideally suited for determination of the Vicat softening temperature (VST) and the determination of creep behavior.

Determination of heat distortion temperature (HDT)
♦ To ISO 75 Parts 1 to 3, and ASTM D648 on thermoplastics, hard rubber, as well as fiber-reinforced plastics and filled thermosetting plastics.

Determination of Vicat softening temperature (VST)
♦ To ISO 306 and ASTM D1525 on thermoplastics.

Determination of creep behavior
♦ Under flexural load


► Advantages ◄

♦ With use of a digital measuring system, high accuracy with standardized calibration can be achieved for the HDT and Vicat.
♦ Operation is simple due to the automatic test sequence. The test is started only once. No further interaction is necessary.
♦ The safety device, including interlocking, provides maximum operator protection
♦ Operation is stand-alone via an integrated capacitive touch display.
♦ Upgrade to testXpert III testing software provides powerful functionalities, such as measured value and control graphics, result determination, data storage, and export functions.
♦ The weights to be applied are automatically determined and displayed for the operator.
♦ Motorized lowering of measuring stations
♦ Motorized application of test weights
♦ Electronic oil level monitoring
