Apparatus is used to determine the Heat Deflection Temperature or the Vi cat Softening Point. All the specimens are charged
with a constant load and immersed in a bath, where temperature is increased at a standard velocity. The attained heat resis-
tance rate of plastic materials is a widely required parameter for product characterization, for quality control, as well as for
evaluating their conformity to the previewed applications.
The optional software system enables to produce graphs showing the deformation of each specimen and
temperature increase versus time. This tester may be used for tests conforming to the following standards: ISO 75, ISO 306,
ASTM 0648, ASTM 0 1525, G81T 1633, G81T 1634. Housing made of steel. Stainless steel inner bath. The designed volume
ensures a very good thermal exchange.
