Automatic Softening Point

ASTM D36, IP 58, ISO 4625

The softening point is the temperature at which a disk of the sample held within a horizontal ring is forced downward a distance of 25.4 mm under the mass of a steel ball as the sample is heated at a prescribed rate in a water or glycerine bath.

The instrument is a benchtop model which houses the components and a touch screen interface. A software running under Microsoft Windows embedded permits to select the test method and the test parameters, run the test automatically, store, retrieve and print data, diagnose and calibrate the instrument.
