Vicat softening temperature is determined and the heat deflection temperature under load on plastics and thermoplastics, available with 3 or 6 testing stations.
Test specimens are charged with a constant load and immersed in a bath, where the temperature is increased at a standard velocity. The attained heat resistance rate of plastic material is a widely required parameter for product characterization, for quality control and for evaluating the conformity to the previewed applications.
The unit consists of a temperature controlled oil bath with three testing stations, each of which may be configured for either HDT or VICAT test methods. The inner bath is constructed in stainless steel and the designed volume ensures a good thermal exchange. The rod and frame members have the same linear thermal expansion coefficient. The weight loading mechanism automatically lowers and raises weights. Test specimens are lowered and raised automatically into/from the oil bath.
With the optional software system it is possible to produce graphs showing the deformation of each specimen and temperature increase versus time.
The system is robust and suited for use in industrial environments as well as laboratory layouts. The HDT Vicat tester complies with the standards ASTM D 1525, ASTM D 648, ISO 306 and ISO 75.
